[Music]  you  [Music]  so before we start on troubleshooting  let me just give the Machine a warm up  here I'm gonna pass this around this is  now this is not a commercial grade you  know fluke multimeter super expensive oh  my god  I'm a pro this is sort of like I want a  multimeter with a clamp-on ammeter you  know light use right my technicians  don't have this they're geeking out and  they're going with more expensive models  because they're doing it that's their  trade it's their livelihood right but in  terms for a boater someone that is using  a multimeter for light use this  multimeter with a clamp on right so you  don't even have to disconnect a circuit  to see what the apps going through the  circuits are going or doing you can just  literally clamp on it you can literally  see is my win lists drawing too much  power as my inverter drawing too much  what's my fridge doing is it  it's my fridge on is it drawing any  power I think I can't hear the  compressor but is it drawing any power  you can literally put that around a  single conductor right the positive or  the negative and you will actually be  able to see if a device is drawing power  or you might be curious which I  encourage everyone to be curious is good  you might be saying I actually want to  know what my loads are drawing on my  boat I don't know like how much is my  fridge draw right how much does  something draw you're just you want to  know you don't have a battery bank  monitor and you don't know what the amps  are and you're kind of curious like how  much does your anchor light draw you'd  be shocked if you don't have an LED one  it is like oh my god you could lose on a  sailboat running that anchor light no  joke a third of your battery you're 1/3  to 1/4 of your battery usage in a day  could be your anchor like that's crazy  just in context that's crazy like your  fridge is 60% some my anchor light on my  Catalina was over almost close to 2 amps  2 amps for 10 hours that's 20 amp hours  my fridge is 60 a third of my daily a  power consumption on my boat  for my fridge was my anchor light I  changed it to LED it literally is a  factor of 111th the anchor light could  stay I mean I don't feel it I mean and  now it's point it's nothing it's a joke  so my anchor light on my boat is on all  the time well you come in in Anchorage  and you see no anchor light there I  don't think it's because people forget  to turn in anchor light probably 50% of  boats don't have anchor lights at least  60 70 % and all of these people don't  know what an anchor light is I'm gonna  assume that they know but let's see why  would they not turn it on I think  they're making a decision they're like  you know what I can't afford to turn it  on I can't so I'm just hoping that  someone's gonna see me at night and I  figured that nobody comes in in  Anchorage at night but this would tell  you if you have a problem you could  measure it quantify it and say you know  what I think next time I'm gonna have a  rigger or someone go up the mast I'm  gonna change my anchor light to an LED  version right and I'm gonna say same  literally gonna draw down my power  consumption by a factor of 90 percent  down that's substantial so I'm gonna  pass this around and that's the one I  would recommend you ball yeah you want  to make sure it's a navigation LED bulb  but yes like not all anchor lights not  all bulbs are the same but yes you can  buy navigation anchor light LED bulbs  right yeah go ahead  Oh anything doesn't matter every you  know this whole thing I didn't  understand like that's the one thing  about engineering is that it took the  mystery of the universe less mysterious  because I remember growing up I was like  why is it that people complain to living  under power lines and they're like oh  you know it's dangerous  magnetic field I'm like yeah the lines  are so far up like what does it matter  well the amps are so great even though  it's high voltage that every wire has  magnetic flux going through it there's a  magnetic field that comes through a wire  a way to offset that is actually  twisting the wire that's why some wires  are twisted twisted pair to offset that  magnetic flux but wires and cables are  so straight and so every wire has  actually a magnetic flux that goes  through it and the orientation of that  field  like this or like this will tell the  direction of if the current is a pull or  a draw a puller or charge I mean so you  can actually tell our my battery is  being charged or discharged they will  actually give you polarity on the  current not just the amount of current  going through but actually am I getting  a charge or am I getting a discharge so  I mean that device is I'm not sure  online I can't remember a hundred and  eighty-nine u.s. or Canadian one hundred  and eighty nine dollars Canadian I don't  know if someone says hired a pro to work  on their boat but the labor rates are  will make that device pay itself pretty  quickly and most of the so-called  experts that work self-proclaim experts  that work on your boat won't have one  because again they're fortunate they're  infused with knowledge and generally  their advice when something's broken is  replace it right they don't diagnose  they don't isolate a problem it's too  hard right and their advice I hear it  all the time someone told me my GPS my  char plotters or my GPS has failed it's  time to replace the char power I'm like  you mean your radar your sounder your  chart plotter all those multiple of  thousands of dollars you're gonna  replace because your external GPS  antenna that's an internal battery has  failed we're gonna just throw it all  away well that's what my advice was I  was told I'm like okay well you could do  that or we could simply replace the  external GPS and everything's still  gonna work so that's what you do with  stuff like that right you isolate a  problem and then you decide as a boat  owner you say okay do I want to spend  more money than I need to because I want  to have a new navigation system or am I  just gonna do what I need to do to  repair what's broken all right so we're  gonna get started about troubleshooting  theory okay troubleshooting is the  endgame in life in terms of technical  skills that's it  you could be an amazing installer an  incredible electrician in terms of doing  something you could be a god the fastest  you understand  but when it comes to troubleshooting  it's a completely different approach  I have technicians who are really great  at installing that might not be so good  at troubleshooting and I have people  that are terrible at installing they  don't have good hand coordination  they're not good but they're great at  troubleshooting because troubleshooting  is a conceptual thing it's a it's about  understanding how things work you don't  need to be a doer to troubleshoot you  need to be someone that understands how  things work once you understand that you  can actually provide direction to  yourself or to others to resolve a  problem but it all comes down to  understanding how something works ok so  just going at it  is not going to help you have to  understand how something works to be  actually effective at troubleshooting  first point is UPS of course with  troubleshooting and I mention that a  little bit earlier generally the problem  is going to be on the interconnections  between devices on your boat that failed  right something powering the device  something feeding the device generally  it can happen the device might have  failed but your first time should be  it's probably not getting what it needs  to work right that should be your first  hunch so that means start working  through the circuit next is what are the  typical problems on boats right you  don't have power to device that's really  pom popular and that's or common and  that's what we talked about electrical a  little bit this morning because that's  an essential skill to know are you am I  getting some sort of voltage at that  device so it can actually work the other  one which is a really good point is  battery voltage is too low remember what  I talked about earlier I said is  everything working when you're on shore  power you have your battery charger  connected and it's powered and  everything works if it works at thirteen  point three thirteen point five volts if  your boat voltage is about twelve then  that means that oh okay good so it's  probably a connection issue that means  that there's so much resistance down the  line that when your battery voltage gets  to twelve the appliance voltage is  maybe ten point five nine point five so  battery voltage is don't ever assume  that what's that the battery is that of  the appliance far from it  you could lose one volt when I've seen  one volt 2 volts 3 volts and it could  get worse and worse I had saw once a  fridge on a boat that had sunk where the  boater had been giving wrong information  that a boat that sink wasn't a really  big deal and he was told to that he  could easily repair it by just changing  the panel and that's the only thing he  had to do was worry about changing the  connectors of the panel now that was  some seriously bad advice that's an  understatement  and we came on board this is after  someone had just changed the panel and  the fridge would never work but there  was 12 volt at the fridge if you  disconnected the wire 12 volt at the  fridge under no-load as soon as you  apply a load if you were able to put  your multimeters on the wiring under  load meaning when the fridge would turn  on the volts would drop the two the  connection was so corroded that as soon  as a small load like a fridge doesn't  draw a lot it's 5 amps 3 amps 4 amps as  soon as that 4 amp load would be applied  the voltage were dropped all the way  down to 2 volts the connections that the  fridge had never been redone the boat  had sunk the fridge had been replaced  but the connections of the fridge had  never been redone and they were corroded  the boat had sunk in salt water  corrosion on the terminal or the  connector right a broken wire can happen  but in my experience and it's extremely  rare wires don't break other than if a  fuse blows or if a terminal gets undone  you know those god-awful Spade  connectors that you we see on our boats  that some builder thought was a really  good idea because it takes too long to  undo a nut and to put a ring connector  on  right you see that on a lot of panels  like they'll actually have push on Spade  connectors right they're not a fork  they're not a ring you likely push them  on and you can pull them out starters  are like that believe it or not I have  that on my boat hotham sound harmony  islands 2006 inaugural trip I'm on the  boat I'm systems engineer I have an  electrical engineer and I have another  electrical engineer we hang around  together of course didn't understand  what the hell was going on fresh out of  school right I know nothing school  doesn't teach you much other than maybe  you can figure it out later  and our starter wouldn't start whether  the issue was the Spade connector on the  starter solar no was loose as soon as  you'd actually apply the starter button  there's a little bit of load to run the  solenoid the voltage would drop and the  starter would barely click but not  enough to be engaged to let the current  go through the solenoid to actually the  starter I didn't understand that didn't  have a clue nobody could figure it out  well we certainly couldn't I don't know  what the hell I was doing but that was  because of a Spade connector right same  thing on the back of the panel those  little connectors can actually come off  or what happens is over time they  they're not as friction right they're  actually they've opened up and you put  them in there they're loose and they  vibrate off right because your boat  doesn't live in a garage where there's  no vibration it's in the water sometimes  the waves you're actually dropping off a  face of a wave all right there's forces  there right so don't worry so much about  a broken wire it can happen but it's  extremely extremely rare it's generally  a connection issue that that you're  gonna find safe wire is definitely a  problem also a little bit rare it's sort  of another break it does happen does  happen if you're going offshore shafe is  a real problem because your boats moving  24/7 everyday all the time there's no  such thing as being a tanker like  there's not a lot of anchors in British  Columbia like you go anywhere else 360  Anchorage's don't exist right I mean we  were in bomb-proof Anchorage's  everywhere here you go in the Caribbean  there's no bomb-proof Anchorage's like  we have here there's very few right and  so at night you're constantly moving and  as you're moving if the wires are not  proper  tied down their chafing right and that  rubbing eventually could cause a short  and that I have to say is a blown fuse  or breaker it's got to be top of your  list remember back when I said the  beginning you got to know where your  fuses are well that's essential because  if you're looking for a fuse or you  decide that you're gonna put your fuses  in your boat sporadically everywhere  throughout the boat as you see fit  you're not gonna put them at the  beginning of this circuit or at the end  of the circuit because you might have a  fuse for the wire and then have a fuse  for the appliance like on my boat I've  decided that I'm gonna fuse all my  appliances with one fuse at the  beginning of the circuit that is both  there to protect the wire and the  appliance all my fuses are at the start  of the circuit even though the appliance  is far away I'm fusing everything at the  beginning of the circuit you could put a  fuse for the wire at the beginning and  then a fuse for the appliance but then  you've got two fuses in their circuits  and I'm not putting them randomly we  talked about that yesterday  I'm putting the fuses at the beginning  of the circuit and it's not a choice  it's a half - okay black and white and  you can't absolutely use your meter to  test an entire circuit in sequence right  and you would do that to continuty or  volts you just chase it down  is there volts here volts there volts  there are no volts why what happened  between here and there  okay so this is a typical enemy a zero  one a three Network I call it old  English I call it Latin it's the way  that things used to communicate with one  another for electronics okay definitely  still out there 1983 so when it was  started nothing came out that we took a  while like May 2000 didn't come out in  2000 k much much later but that's when  it's got start spearheaded  the challenge with this type of topology  and by the way pretty much every single  one of you have that on your boat if you  don't know you do you do devices all  have enemy is there 183 very few have  enemy in 2000 only and all older devices  prior to probably 2007-2008 are gonna be  0 183 only or C talk which is a  proprietary bus network that's owned by  Reimer ena the challenge with this type  of topology when you're trying to  troubleshoot and we're going to talk a  little bit about that your  troubleshooting systems is that this  system is sort of like human  communication there's a talker and  there's a listener and the talker and  the listener are on separate so when I  talk to someone they listen and when  they talk right it's on a different  Channel so it's not a single channel  communication you'll have one wire where  I talk they receive another wire where  they talk and then I receive so a talker  listener okay sender receiver everything  is about who's doing the talking and  who's doing the listening and then it  gets more complicated  I can talk to many people in a room but  not many in the room can talk to me at  the same time right because there would  be too much noise so then you have to  start making decisions I am for example  a multifunctional display or a GPS I  will send my GPS information to multiple  places that want to listen to it  chartplotter maybe a radar a VHF right  but then the VHF might only communicate  on one port to the chartplotter  on autopilot might be sent and receive  only for routing information it might  receive GPS information for route and it  might send its heading to two places and  might send it to the radar and it might  send it to the tar plotter  so you have to constantly and what I  would say when we do  with enemies there 183 and there's a  reason why they went to 2,000 if I'm  losing you it's because it gets intense  and this is a simple Network like we do  some networks that have 20 devices 30  devices and this is where you got to  draw it out  bravado has no place with electronics if  you think you're smarter than everyone  else and you're just gonna do it  congratulations your life will be  definitely more complicated and it needs  to be I would say if you have anything  enemy a what you want to do is you want  to remember that everything is contacts  driven and especially we get this all  the time because most of our VHF Sarn on  enemy a mm but they want to receive an  enemy 0 1 a3 signal for GPS position  right because otherwise that DFC  functionality is not going to work but  if you're actually interconnecting the  wires on the wrong position you're  having a talker talk to a talker and a  receiver to a receiver nothing is going  to go through right  that's why enemy's n1 a3 has its  limitations and why enemy 2,000 which is  a bus topology is much better here's I'm  not trying to scare you but this is  where it gets interesting is now this is  what it gets to on the bigger boats you  know on those trawlers on those big  boats that had older technology that  we're trying to integrate everything  these are all these sort of devices you  know to gps's are going to one device  then you got multiplexers then you might  even have sometimes what you're gonna  have to happen is you're gonna we talked  about it there's so much information  coming I need to start prioritizing  information from one place over another  place then you literally have to go into  a laptop and say I don't want these  sentences to go through I know you've  got all this information but I don't  care I want you to block 99 of them and  I only want you to let one through so  you're actually starting block info  you're letting it through so folks that  have maybe this starts happening around  50 footer 50 55 60 70 80 footer at that  range you're starting to have a network  like that and then that way where it's  not easy because there's a lot of pieces  in the puzzle that are actually trying  to make it all work and that all happens  at enemies there 183  so if you're troubleshooting in enemies  in 183 just remember to go very slowly  look at the color codes and remember  when someone says I'm a talker and  receiver the other one you don't connect  talker to talker and receiver to  receiver a talker talks to receiver  right and the talker here talks to  receiver down below  everything is context driven I see this  all the time people are connecting  talker to doctor receiver to receiver  and nothing goes through and this most  simplest simplest example would be VHF  radios right that's the normal way that  people interconnect their VHF radios for  GPS is over enemy 1 0 183 if you're  lucky and have to have an amias nmea  2000 Network then it makes your life  much easier because it's a bus topology  you don't have to worry about any of  that any questions before I leave any a  0 183 on a boat yeah that's another good  question how would you see so you've  done the work and and you want to figure  out a lot of MFDs will actually have  you'll go into a port you'll go and  start going the menu so now you're going  you're putting your hat on you're like  we're going deep they'll go through a  menu you're gonna go Communications  enemies there 183 and you're gonna go  buffer or something you're gonna have  some sort of seal and they're gonna a  stream of consciousness Meijin remember  the matrix that's what it is and it's  going to start showing you all these  lines and then you can start it and stop  it because it's constantly going like  just start filling up the buffer start  stop and then you go through the lines  and you can start seeing all the  sentences that are Rafi received which  don't make any sense you they're not  saying like depth depth receive is 48.4  no it's a little bit more cryptic than  that and then you go through and you're  like oh yeah I'm looking for for example  we're troubleshooting an auto pilot  we're saying is the autopilot sending  heading we're losing heading on the  chart plotter so we go into the buffer  on this chart plotter and we're looking  and we're seeing where's the heading  sentence I'm not seeing it and sometimes  what happens this is overcrowded there's  too much information happening on a  multiplexer there's so much information  coming in it's getting lost and then so  when you do is the process of  elimination let's remove all variables  let's turn everything off let's just  have autopilot only talking to chart  plotter oh then it starts slowing down  you're like okay it's there as soon as  we turn one thing okay that's fine  you turn another and it's we're losing  turn and that fourth one then it starts  to be sporadic you're like Oh  overloading of information on that bus  and that's where then you go can we  increase the bus speed oh yeah if we're  not using a is it's only forty eight  hundred we could go to thirty-eight  hundred thirty-eight thousand four  hundred let's increase the bus speed go  faster now does it work yeah higher  throughput no problem so you do the  Diagnostics on your probably  multifunctional display you're never  going to be able to do that on an op  eyelet or an instrument or if you  totally geek out then you would have a  device like this and some of them will  actually have a USB port and you can  then go with software and then you're  talking like full geek you're looking at  the sentences and everything else and  now that's not probably for the light of  heart you know that the rule is and  honestly I'm the same like I'm good up  to a certain level but I've got a few  guys on my team that are way better than  I am and everything has a pay grade  right like I I'm a concept guy but I'm  not out in the field like some of my  technicians some some of them every time  it gets really really really intense I'm  like congratulations you're paid to  think  all right I'm considering you my little  Navy SEAL right you're making the big  bucks  so I'm putting you drop dropping you  right in there and you're gonna figure  it out and then they ask me how much  time you give me I'm like we've got to  go ahead four hours eight hours whatever  you go in there and start scratching  your head and if you want to  put up a chat channel we'll put up  multiple people you want someone else  let us know and then everyone at one  points get to a top level and I get to a  top level too and sometimes my  technicians it gets well one of them  maybe not but most of them get to top  level and like okay who can we talk to  ask a friend ask an engineer ask a  colleague in another business right then  you start relying on other people your  the point is with troubleshooting you're  always gonna find a limit to your own  skill set and then you start bringing in  experts right so those are sort of the  limitations of enemies and zero one  eighty three and as we started all of us  adding more and more and more electronic  devices on our boats right because  remember before it was like you had a  depth sounder maybe a VHF and then okay  you went crazy you had to win instrument  okay then it got really crazy you  decided to add a GPS right but then it  just started going past that right it  was like then it's like a GPS and then I  want a is then I'm having like multiple  sensors then I'm like for example here  you've got some of those modules we're  doing engine integration and enemy is  there 183 right now I'm one information  it just it just went full crazy and so  it wasn't enough and so then what they  did they invented this now this is a  Garmin view of an enemy a two thousand  backbone but doesn't matter we're gonna  talk about Garmin for uno everyone plays  nice an enemy 2000 so what you have here  are T's okay by the way this was not  invented by the marine industry this was  actually invented by Bosch this is used  in robotics and they simply adapted this  technology to go on boats okay it's a  control network can you have one single  backbone that backbone has a maximum  length but for most of us it's not going  to be a challenge on a big big boat like  a hundred footer  then it starts being a challenge as  you've got to go multiple levels up on a  boat but on a normal boat like a 50 60  20 30 40 unless you get this super nice  super yacht but like I'm big big boat  you're not gonna have a big challenge  with this backbone length the in  seneschal key and again remember this is  something people ask me this all the  time now because we've got people I've  got people calling me and I'm  troubleshooting problems from everywhere  now like not even in the continent and  they're like Jeff I would like you to be  here but how do I go about finding  someone locally and I always think about  how I do and I find someone myself I'm  like first thing is you never ask  someone a simple question where they're  gonna know the answer and then tell you  what you want to hear because everyone  in general there might not be as honest  or forthcoming about their  troubleshooting skills because they  simply want the work so it's not good  enough to say to someone oh do you know  any me mm how many people are gonna say  no the good people are gonna say no if  they don't know but there's a subset of  people that will say yes and they don't  know and so what you want to do is you  want to suss out are they really  qualified or they pretending to be  qualified and why I bring that up is  this is pretty straightforward to  install an enemy mm backbone but I  cannot tell you how many enemy mm  backbones I've seen installed by so  called people that know that is wrong  it's crazy right because people are just  amateurs and they just trying it and  they don't educate themselves like my  technicians myself I went through an  enemy 2000 certification right sort of  what you're doing I'm also curious I'm  like okay show me how it works  I want to know so the essential thing  and this is not going to be the case on  many of your boats a lot of people  thinks these are endcaps these are  called you see here it's hard to see  female resister male resister these are  absolutely essential and there can only  be two on a lot of boats what they're  doing is they don't understand that  there's a backbone of a thing or these  are just plugs plug it and what they're  doing is they're not having a backbone  to the boat they're actually having  branches and everything else and it's  not one continuous backbone it actually  they have Spurs and it goes everywhere  and they don't understand that  you need only one resistor at the end  and another resistor at the end of the  backbone so that's a big problem with  enemies they're on a zero mm is that the  person installing it doesn't draw it out  right because if you draw it out you see  right away that there's a problem or  even if the Installer didn't know you'd  look at it you're like it looks like  nothing I've ever seen before  and like well that looks wrong and then  you know enough to say well maybe I  should call someone who might know more  than whoever did my system oh you do  absolutely absolutely you do absolutely  there is voltage drop ish and that's why  there's a maximum number of nodes and  that is why the power cable should be in  the middle  if the backbone is so big what you'll  end up having is multiple power supplies  that are actually isolated from one  another on big boats like I've done  boats that have three decks you know  we're doing a whole boat digitizing  everything like these are massive  projects thousands and thousands of  hours we'll have multiple power supplies  like that where the power supplies are  actually completely separate they're not  overlapping on one another like one does  you know port one does star Burt and  then it will have even separate networks  and then you start bridging them that  gets in the stupid realm again  anything's possible remember but we're  going to keep it vanilla simple right  let's keep it simple  so what you would do on a normal boat is  if you're installing a backbone and  you're going from you know first deck  started from the engine room you go down  go up into the fly bridge the pilot  house maybe go to the fly bridge go up  to their arch right you're probably  gonna want to install this power supply  Midway so maybe you put it in for  example in the pilot house right it's  kind of halfway on the circuit but again  you've got to draw it out so you see how  drawing it out makes it easy because  you'll see right away if you don't think  you have a problem then just show it to  someone right and I've got people that  do that all the time with design we do  this stuff design remotely people like  Jeff I've got an idea of an enemy mm  backbone I'm doing can you guys provide  consultation I just want you to tell me  where I got it wrong ask questions  and then they'll send me their diagram  I'm like okay here there that this that  like thank you and then they go and  install an implement so you can actually  have these backbone extension cable you  can have them everywhere or what we end  up doing too is will end up doing  service loops because you can actually  do what are called feel service ends so  maybe you've got nothing in the engine  room you need now but maybe one day you  will will actually route the cable  thinking okay well maybe they'll want a  battery monitor sensor maybe they'll  want a temperature sensor in the bilge  maybe they'll want a fire alarm in the  bilge and they want nmea 2000 to relay  that information to the bridge  so we'll put basically loops in places  where we think we might need to cut the  cable and install the T later on because  the beauty of an enemy mm backbone is  that you can actually interconnect all  these different drops onto the backbone  and that information goes any to any  it's a bus when you're troubleshooting  one of these networks besides actually  figuring out that you actually have the  right resistance and that your backbone  is intact what you'll probably end up  doing is actually turning everything off  and then turning things one at a time  right it's all about disconnect so you  physically to turn them on you'll  actually have to disconnect them and say  okay I only have one device does it work  I putting a second one does it work  everything is about incremental change  it's very hard to diagnose something if  you're trying to do it all at once now  there is actually merit Ron sells a  diagnose device you can have a laptop  with a software with an enemy a 2002 USB  gateway so I've got three of my  technicians that have that they'll go in  but then you're starting to be like this  tech right you're going in the network  you're putting a T in you're diagnosing  you're seeing the bus your not gonna be  able to do that most of you right you're  gonna take a more simple approach you're  gonna be like well let's find a fault is  there a faulty device on the network  that's causing my bus to go down right  and then you'll start doing it one at a  time and then try to see if there's  one that's miss misbehaving that's  taking the whole network down but that's  how you troubleshoot nmea 2000 Network  any questions on enemy 2000  troubleshooting yeah go ahead correct  yeah  yeah there's a good point but it depends  yeah that's a that's a great question  you you'd have to balance both  so it's both every one of those devices  is known by what's called a Len like  what the hell is a land a Len is an  acronym for load equivalent number every  Len is five milliamps they're only  allowed to ever draw more than five amps  a twenty Len which is one app from the  backbone meaning if you have for example  a intelligent transducer that has no  other power coming from anywhere else  this device can get power from the  backbone only if it draws no more than  one app a fuel sensor same thing now  your chartplotter here is not drawing  power from the backbone it's two big  strong three four amps it's got its own  power supply and effectively it's not  drawing anything from the backbone your  instrument here could be enemy 82,000  powered only or it could be enemy in  2000 connectivity and then power comes  separately so it you have to think  you're like Oh am i drawing anything  what's the Len load on this Oh  okay where is it what's the distance  merit Ron makes an amazing app online  where you can actually start dropping  all of this and actually do what's  called it configurator like you'll  actually build your enemy 2000 online  build it all out and then you can start  figuring out if you're loading it too  much these cables have maximum distances  they're only good to 6 meters you can  never have your backbone further away  than 6 meter from any appliance so  that's why the backbone has to snake  throughout the boat right and then when  you snake it you have to think okay what  are the potential things that one day  I'm going to want to bring to that  backbone because the beauty of this is  that think about right now on about your  gauges on your fly bridge or wherever it  is it could be on your sailboat they  need there's multiple wires that are  leaving the engines coming back to one  or another help right the beauty of this  is you decide that now you want you've  run an Emmy mm backbone in your engine  room you've brought it to a pilot house  you brought in to fly bridge you brought  it to your arch and now one day you have  a GPS on your arch you're like you know  what it'd be nice to have a weather  station really nice now the only thing  you have to do is install the weather  station put a tee in the arch the cable  is already there and suddenly the  weather station information is going to  appear on any device that chooses to  display weather information it could be  an instrument in the half cockpit it  could be in a pilot house or it can be  in the flybridge now the other could be  true - what if you want to have a smoke  detector and you don't want to run wires  from your smoke detector because you  can't hear the smoke detector because  it's in your engine room and you want to  have it on your flybridge well you would  install an enamine mm smoke detector in  your engine room plug it in and suddenly  the device on your fly bridge would be  able to see an alarm from a smoke  detector without having to run a wire  that's why it's called the bus it can  carry a lot of info yes yeah 183 that's  correct  your the point is could one of these  devices actually bring the whole network  down yes it's possible  yeah it's true extremely rare though  extremely rare to be honest  the challenge was zero on a three it's  such a mine scratcher  I think it's so involved most people can  get it and I guy by the way it's great  for me by the way like selfishly as a  business owner I love zr1 83 I love it  it's I mean it's great I get hours I  mean it's awesome I can do it I try I  failed I get it all the time okay sure  send a Navy SEAL down no problem we'll  do it no problem I love it  the challenge is that the implementation  of a zero 183 Network is extremely hard  and by the way does not allow for any  redundancy right  on this network we don't show a GPS but  I can actually go in and I can say GPS  one is your primary GPS two is a  secondary GPS three is a third and I can  actually have five GPS as on the network  all online and if I lose one the  secondary picks up I can say you know  what that's secondary on the arch that's  a good one the third that's in the  flybridge that's kind of for that we've  got a little bit of occlusion and it's  not great that one out actually have as  my third so you can start having backups  this takes people out of the equation I  much rather deal with equipment failure  than human involvement in a network  sorry but we're mostly we're always the  problem right I mean let's be honest yes  no zero one eight three would be  connected through and I do this all the  time this is how you integrate old and  you remember when I saying or you can  have an old autopilot and you have a new  complete system you do that through a  converter and that converter sorry is  something like this this is hard to see  here because it's so white it's an enemy  2002 as an amazing 183 I put that device  i buy that device in like boxes like  crates and then it's going to connect to  enemy 2000 yeah it will go to a team  yeah yeah what the output of that is a  drop and that drop connects to a team  right yes question yeah so the question  is why I'm trying I'm going to try to  repeat the question just so everyone can  hear it is if you've got an M use there  183 Network on your boat do you convert  in multiple places and then bring it to  a bus or do you just leave the network  alone and then convert it in one  location is that correct  you'll most likely convert in one  location unless your boat is so big that  you have multiple locations of enemies  there 183 oh yes absolutely what I do  work on a boat not myself I mean our  outfit I'm always looking to the future  right and I know that I don't know what  we're gonna do five years 10 years 15  years down the road so when I put a 10  mm backbone I put a 10 mm back belt and  I basically strongly encourage someone  to look into the future and make their  life easy by not having to run another  cable ever again from the engine room  you imagine the cost savings if my job  was if everything was Wireless on a boat  my labor revenue would go down by a  factor of probably 80 to 85% everything  about a boat is how do I go from here to  there it is crazy that takes so much  effort right so much effort when you  install an enemy mm backbone you're  saying I'm gonna go through that pain  once right and then every time I add a  device unless your boat is super huge  and you're getting to this crazy point  where you have too many nodes but you  won't you'll run it once and every time  you just add a drop and then that  information shows up and everywhere and  by the way there is no limit like after  that you just bridge networks and on the  big boats we don't run one backbone  cable we run two we'd actually go  redundancy right like we're thinking  that cable took us five days to run  through the boat I'm not gonna run five  days cable and say oh we have a break  one day what can I do I'm like no I run  everything twice like literally at the  one time I'm like you're pulling two  cables same thing with IP when we run  Ethernet cables for IP cameras I don't  say oh it's gonna take us like 12 hours  to run from a wing station down to the  engine room  we're gonna run one cable and if it  breaks well we'll just run another one  I'm like Ethernet cable is free you run  too and you have a backup there and sure  enough one day cable fails you're like  no problem there's a backup right there  plug it in and works the engineers that  are onboard those boats are like oh my  god thank you I'm like you're  welcome right redundancy any other  questions on MA mm I'll get you just one  second yeah so PGN is that perimeter  group number I think is what it is  something like that  it's sort of like a unique identifier  for enemy mm there's so much information  like what's depth right so it has a PGM  everything has sort of like a variable  right what is that variable and he's  right I mean the question is well maybe  this outputs information but does this  device able to see it yeah okay but  honestly unless you're right off field  and you're going super deep into really  weird sensors a deaf PGN is gonna be  pretty much shown by every instrument  right like these are now called these  marina instruments are sort of like  unlike in the past you were thinking  about a Raymarine you know that wind  instrument that was an analog it only  showed one thing now you buy a Garmin GM  i-20 or you buy a Raymarine instrument  that device can do multiple things it's  a portal to your data network now it  will not do all p.g ends and that's true  if it gets too technical like for  example we did a boat where we converted  the whole boat to everything on the  engines got converted to digital the  owner wanted to know everything  digitally because the upper helm didn't  have enough information on the gauges it  was kind of limited and so we did  digitize the whole engines everything on  the engine we digitized now knowing  boost pressure or if your turbo  temperature what it is that's not going  to show up on a GM at 10 or GMI 20 right  like if you on that engine we had 20  variables for the engine like we put  sensors everywhere like the guy went  let's get out together I'm like let's do  it like I'm loving this right like god  this is where I'm paid to be an engineer  and I'm like this is amazing sure you're  not going to  see that on your Garmin chartplotter at  one point the Garmin sharp line goes  really like like I'd never even thought  of that so then that's where you need  sort of a proprietary screen like a  marathon screen that goes I do  everything for you and then you  configure that on a merit Rahn screen  right so there are limitations but for  most of us and honestly that's 99% of us  most of us are not going to encounter  that problem most of us are doing pretty  common things I'm always thinking about  gosh and distribution like most of us  are right in the middle there's people  at the end I'm off the spectrum clearly  like I geek out and I'm away three three  standards of deviation off and I'm  probably all by myself but most people  are in the middle and most of the  equipment will do what everyone wants to  do if you can't then you have to spend  more money on a more expensive screen  from a you know someone like Mara Tron  that basically I'll do everything for  you question do you have a question in  the back I have can you tell me what  navigation system you have oh yeah they  do that that's for the instrument that's  only for the instruments no that's for  yeah that's only that's only for  instruments yeah your charger still  standalone though yeah well though  they're gonna be connected via any me mm  thick there will be completely but  there's standalone pieces I'll show you  another device later on I'll show you a  little bit what that looks like I'll  bring that up yeah yeah rhe Marines  awesome memory marine basically calls if  everyone says Bravo they're like alpha  everyone says up there like oh no up is  actually she you should call it down  there like it's like all about confusion  I get this all the time people are like  oh my god I have a Raymarine system on  my boat and I'm thinking of upgrading my  electronics I think I can only ever have  Raymarine forever on my boat because my  boat came from the factory from  Raymarine and I've been led to believe  that Raymarine is the only thing  that will ever work on my boat how am i  yeah I know they want to make it sticky  but it's not that sticky like so of  course when they Garmin the side plane  eyes they're like oh it's called an  amine mm oh we're not going to change  the name and we're gonna call it MEA mm  we marine on the other hand they're like  oh no it's not  enemy mm we're gonna call it sea talk ng  C talk next generation it's actually  enemy mm but they change the connectors  they're like oh no no it wouldn't work  then you buy a pig tail that goes early  from enemy in 2002 see talkin G so it's  all about creating confusion so that the  people that do it themselves  look at them they're like oh this is too  hard I'm not going down that path I'm  just gonna buy Raymarine always forever  and then my life is gonna be easy but  they do that to confuse the masses  anybody who does electronics they're  like yeah come on excuse Li that's the  roadblock you're gonna have to try  harder right it's not because you call  something a different name that I'm like  really gonna lose it I can translate all  right so again sorry for the whitewash  with the projector it looks awesome on a  screen but this is an example of a  marathon here and you can actually see  you know we've got a temperature this is  actually pretty cool like this is a  depth sounder that actually calculates  depth and we use this all the time on  tons of boats as a redundant transducer  that actually calculates depth inside  the transducer and then it outputs depth  literally on that cable so any device on  the network that can read depth will get  it  so trawlers people that go up north or  people that are going up to Queen  Charlotte's and they're like I've got  only one depth transducer I'm like okay  maybe you have one let's install another  one on a different frequency make it  smart any device can see it it's not a  you're not gonna see bottom imaging but  you're gonna get it depth so I do that I  just did that on a hundred footer like  we put one in and we're like putting a  second one it's $200 why not have two  depth transducers depth is useful like  it's right up there there's propulsion  steering which is kind of one in the  same there's a VHF radio and then  there's depth sorta in that order is  your top three things on your boat for  safety  so having an intelligent transducer you  can do that with enemy mm they're not  expensive it's not like a $5,000 line  item $200 right put one in the boat the  code is you see they're always showing  back to that question where's the ma mm  cable is it in the middle right most of  the time it is assuming the network is  balanced right you got a GPS antenna  here remember I was talking about before  the radar that doesn't radar really that  doesn't work because there was no  heading smart heading sensor that's this  solid-state compass Merritt Ron does one  Sam rod does one everybody does one  Garmin makes two variations an expensive  one not expensive one then you've got  this another one this is the display  that shows everything Merritt Ron has  them now they're starting to become  pretty competitive in their screen  pricing you can buy some that are just  instruments which is nice as well right  and then this device that pretty much  every one of my technicians have or if  you have a laptop on your boat and you  want to see all the information off your  enemy mm backbone you're gonna get a USB  to enemy a 2000 converter this is just a  more stuff of basically this right  simpler more and then it just gets more  and more and more and more custom is a  strong word it's tailored but you can  build one in yourself like honestly most  of us are gonna have a reasonable boat  you could draw it even up to 30 40 50  feet you can draw this out by yourself  you just run a snake around your boat  and then you say what are the things in  that boat that you're gonna want to  connect to right it's not that  complicated but again it's the back to  the thing draw it out don't do anything  without a plan and I just want to  emphasize this how many great things in  life have worked out without a plan they  didn't make it to the moon by just  trying there is a little bit of work  that happened before that anything of  significance a house a building anything  starts with a concept  like okay let's figure this out put it  on paper and then share it with someone  oh look I'm doing this what do you think  are your missing if you do it on your  boat and you're like oh I did it enemy  mm backbone on my boat what do you think  all the inputs gonna be a phenomenal you  can't see it it's everywhere hidden well  I think it's great I mean where do you  what is someone what kind of feedback  and you possibly have if you're doing  something that can't be seen  yeah you you can you depends if you have  a point there where two wires were  joined a male and female were joined  because the cabling can comes in lengths  if you have already a joined there you  would undo the joint put a TN now in  some situations you don't have you never  thought you would have one there you can  literally cut the cable and you would  put what's called a field service  terminal right like Ethernet cables I  know we buy them at Future Shop or Best  Buy and they have ends on the end right  rj45 but you can actually cut a cable  and put your own end on it same thing  with this there are field service  terminals that you can put for any me mm  so you can retrofit things no it's got  five strands five strands a shield a  pair for power and a pair for comm  communications okay by the way I could  do an enemy 2000 presentation for a  weekend like you want to geek out like  that I could do I mean I'd love I'd love  to do a university course you could  spend a year just geeking out on every  single topic it could be multi-day  courses just on every single one but I  don't think I'd have a large audience  I'm really glad that you're here share  my enthusiasm for this I'm surprised the  room is this full to be honest alright  any other questions on any of mm before  we start looking at other things here  okay all right I just want to talk  because we're going to talk a little bit  about navin then we're going to do a  little bit of electrical for  troubleshooting as well so we're gonna  do about another about  minutes of nav here's a high-level  overview of the world today I want you  to remember that any day in 2000 isn't  really something that has a significant  enough baud rate or ability to  communicate large files if you're  streaming video images cameras Sounders  radars these are large that's a lot of  data that will never be on an enemy  a2000 backbone that is not enemy in 2000  is for small data like depth temperature  wind speed a is little tidbits of  information right not big so you look at  this the blue line here on this example  from Garmin is enemy mm meaning all  these devices are sharing enemy mm  information but it's low volume it's not  a lot of data the baud rate is still  within the land of the reasonable once  you go to high amount of data you have  to have now of course Garmin called it  the Garmin marine network but ultimately  it is literally Ethernet that's what it  is like we have at home at the office  the world runs on this all of this is  Ethernet so that means a radar sounder  your chart plotters other chart plotters  all those devices that have high amount  of data are going to be over a Ethernet  network so on modern navigation systems  when you're talking from one device  through the other and this has been  around since 2004 probably when two  devices are talking and sharing data  then I'm thinking Raymarine CSeries and  where you would configure one as a  master and the other one is slave they  would be sharing radar imaging you know  one one screen would have the radar and  then that radar would be sent the image  to the other screen that was done over  Ethernet of course Ray Marina in ecology  through net they have its own name but  at the end of the day it's a Ethernet  network right all the companies are  giving them no names to make it  complicated but it's Ethernet so you  have two net  now on a boat you have and realistically  probably three you have Ethernet you  have enemy 2004 those legacy pieces of  equipment that you haven't changed gme  2000 there's enemies 0 183 and then you  have proprietary networks like c talk  which is another bus topology network  there are a marine zone and you can go  from c talk to enemy 2000 via converters  so on my boat my instruments are all sea  talk miry marine instruments and i'm  converting all those instruments c talk  to enemy 2000 via converter and that  converter is not expensive it's about  one hundred and fifty dollars hundred  dollars and so i'm converting c talk  information to enemy 2000 so it's sort  of like languages there's all different  sort of languages in the world  you want translators right how do you  connect all these different systems on  your boat and again draw it out because  if you have a if you have wind on sea  talk and you're wondering why your  chartplotter  is not seeing wind anymore well where  could it be is it because you don't have  wind or is that you still have win on  your sea talk network but their  translator the device that converts sea  talk to me in 2000 has failed it's not  getting powered the fuse blew and got  disconnected right so it's about drawing  things out that's how you get to be a  good troubleshooter you have to know how  things are connected otherwise it's just  magic  just magic it's like well I don't know I  just don't know and then you do what  most people do which but I'm trying to  train is you call someone delegate the  responsibility and that's probably 40%  of our businesses there's people are  just on fire call it's like you don't  know what you're doing tomorrow but  there's gonna be a call tonight I know  I'm gonna get a call and somewhere  tomorrow you're gonna go solve a problem  we don't know what the problem is but  it's gonna happen and your job is to go  solve a problem that nobody has called  us yet for so break fix right service  but you can make your life easier if you  know what's on your boat and the  technicians life easier too if they know  I've beside other wise they're going to  have to figure it all out and that is it  expensive and frustrating because  getting something to work is not as  satisfying as putting something new on  your boat alright so here's another  example of what a typical topology looks  like right you've got you know  instrument an autopilot a VHF and a is  transponder enemy 2000 all on a bus and  then that bus is talking also to char  plotters and then you have a switch  which talks char plotter chartplotter  sounder radar and on some boats you'll  have two radars right you'll have two  Sounders some boats we did a boat  powerboat they had six seven sharp  laughter's all right it just starts  adding and then you've got cameras that  come in there so you could also start  having IP cameras that can come in these  devices notice this transducer is  connected to the back of this sounder  box very important to know where's my  transducer connected on my boat does it  go to a black box does it go to an  instrument or does it go directly to in  MFD a device that have a black box  capability built into it right because  if it comes to the black if it comes  right to your display that's easy to  troubleshoot right you start seeing the  settings a lot of times what happens is  an owner goes in the settings playing  with the sounder changes the transducer  type stops working then we go in there  we reach ange it the way it used to be  starts working but maybe the black box  died you know there was a bad batch of  black boxes now from one manufacturer  shall name on shall name nameless for a  period of time and the black boxes would  just die they stopped working so we'd  have to find the black box get it get it  a refurbished one and you one change the  black box and now the transducer would  work or if your network completely goes  down why does nothing talk to one  another oh well maybe the switch went  out maybe the power to the switch right  now that's would be the only thing that  would explain that this device this  device this device and this device don't  see one another how could all devices  what's the single point of failure right  are the networks which win down on  bigger boats you have multiple network  switches and on top of it what's  interesting is nowadays what they tried  is they make it easy  now they'll have some of these devices  will have three network ports built-in  so some devices are actually a switch  built into them to make connective it  easy so you can have it displayed in  your house have a radar connected to it  another chart plotter right beside and  have the sounder connected to the back  of it no switch needed they're trying to  make it easy but you have to draw it out  any questions on a generic kind of nav  system that you could encounter in a  boat  alright we're powering through everyone  we're good we're good here all right  remember rule number one nothing's ever  easy is that's what it looks like you  got to be okay with it and notice the  power to write power is a big issue for  troubleshooting here's an example and I  decided to bring this in because this is  a typical Raymarine had a huge market  chair in the past and this is a C Series  II series right this is a good example  of a network that I find on boats all  the time  I mean anybody's show of hands anybody  room here with sri marine c series or a  series on board one two three four five  six yeah pretty common I had on my boat  they had a huge market chair  big OEM base right installed at the  factory actually not a bad product line  not a bad product I really liked it so  you got your chart plotter you could  have multiple right you know they had a  C 70 C 80 C 120 and then they did an EI  de 120 challenge for upgrading was and  it's not their fault that's the world  that was built back then this chart  plotter is connected directly to a radar  via an analog wire right like multiple  strands today's today's radars are  actually digital meaning they have  Ethernet and separate power but if you  have a typical network system like this  on your boat when you change the chart  plotter you actually change the radar  because there's no more analog radar  connectivity so that's a big challenge  you literally have to change not only  the de radar the cable right so you  decide to change its sharp lauder you're  changing the radar and the cable and by  the way this is nice  everything's closed but on your boat  changing a radar cable if you have it on  the mast on your sailboat welcome to a  world of pain writing a radar cable from  the masts down to your chart plotter up  in the binnacle on a sailboat is not a  two-hour task if you do that you will be  seriously disappointed with your time  management skills it takes a long time  to route a cable from a mass to a  binnacle on a sailboat but that's the  pain you have because at the end of the  day back then it was non digital you'll  notice sea talk instruments this is what  I have on my boat right all here this is  common right you had the digital sounder  module that's that DSM module that black  box that converts a transducer to a  video image that other devices could see  so you would literally have and notice  here the radar is connected directly to  a chart plotter not to the switch right  on modern stuff that's connected to the  switch now this one is actually if it  doesn't if this is on there's no radar  here in here and notice also how that  screen is bigger than the other ones why  because back then they would make master  slaves right remote cameras you could  even do I had PC based navigation you  could actually have it was called Ray  marine navigation system 6.0 where I had  my laptop being a replication of this in  the cockpit not in the cockpit but in  the nav station so the reality is this  there is no generic playbook to solve an  electronic problem because an electronic  problem is specific to the equipment  that you have onboard and it's specific  in the sense of the topology changes  depending not only on the manufacturer  but the generation of the equipment if  this if you've got a Raymarine see  classic system it's not the same as  having a Raymarine current system you're  going to be looking at the problem  completely differently because they're  not networked the same okay  this is an example of a Garmin system  more modern and you'll notice there's no  switch on here right the garment is  directly connected to chart plotter  another chart plotter directly connected  to their notice the transducer goes  right into here then shares that  information up here and then over enemy  a2000 all this information is chair so  that's a common setup you know like we  do a lot of power boats lower house  upper helm will put a chart plotter with  a built-in tread sounder device called  the XS V down below and that's what that  is XS V right here we'll plug the  transducer into here the network cable  up there there and then a network cable  from here up to there now if this device  is off there's no sounder here or if  this is off there's no radar there right  so there's you know you gotta balance it  but it's all about balancing money time  right all those are variables remember  perfection is very hard to achieve and  expensive notice there's a camera coming  in they have built-in decoders now but  once you want more cameras you need a  separate decoder and then you feel it as  a video image they can do a couple of  cameras I think but some boats they want  four so they want eight so that's how  you would go you want to have your  layout think about your layout what is  connected to what how is it  communicating this is communicate via  ethernet right and then power is the big  one right make sure there's actually  power of the device but worrying about a  break in a cable to be honest it's such  an outlier it's so rare so rare  unless of course and I always ask the  question you know I got someone that's  got a radar arch has anybody been  drilling in your radar arch recently  right like you don't know canvas guy no  okay yes oh really  Oh interesting somebody was working up  on your Bimini beside your radar arch  they were mounting stuff sure enough one  boat went right through a cable drilled  create a short okay that's easy right  spec's expensive to fix but you know  what I can live with that because at  least we didn't look around too long to  fix it right to find out what the  problem was any questions on this is  probably a very vanilla standard auto  not all about navigation system on a  boat between anywhere between probably  25 to 50 feet any questions on what that  looks like or how you would go about  troubleshooting this any comments  feedbacks does that make sense  you got basically Ethernet here enemy  2000 over there so this is just simply  an extension of what we talked about  notice how there's an AIS 600 here right  that's pretty easy and they're just  showing one antennas but you can have  multiple GPS antennas on this now here's  where it yeah go ahead of course that's  that's that's called pain that's a lot  of pain has a lot of pain yeah it's  funny you know it's a weird world  yeah you just paying you go slowly map  it out it's like a flashlight imagine  yourself in a very very dark room you  just have a laser pointer and you're  like oh now I got two connectors they're  home wonder where those are put them on  a diagram question mark question mark  next time you open something else you  see oh that's there question mark erase  with eraser now that that you can I mean  unless you really want and that's hard  especially on the smaller boats you  don't have space a lot of this stuff is  so packed in there you know like you buy  a 35-foot or boathouse I'm not sure what  your size is but I one point you get you  get so much information and you go down  these bundles and you have no idea right  like even on a 50-foot boat sailboat  they're small to power boats is  different then you start having a little  bit more space but I work on you know  grainy white sir ocean or Boston whalers  they're 30 feet they have as much stuff  as their 45 foot trawler they're just a  smaller boat but everything's on that  boat and then the wiring is really tight  because you can't see anything and then  behind panels but you start mapping  taking pictures you know I like it  sometimes I meet these owners and we're  going through their system together we  do this sir  is called an electrical orientation it's  not electrical audit it's sort of like I  don't know anything on my boat I'm not  worried that it's not safe but can you  tell me how it all plays together and I  got this one owner once he had his iPad  and he's seeing pictures of everything  and then he's drawing with a PDF rider  on top what everything is he's like well  we don't know what that is and I'm like  I don't know I've never seen that before  but that has a question mark that's a  blank you got a wonder every time you're  looking through that I wonder what that  does  and then you start having these  open-ended questions that don't have an  answer but eventually will you'll never  be able to answer it all at once  you couldn't even it would be even to  delegate that tasks to someone would be  not days it would be a full like it's an  expedition it'd be like stay on my vote  and when you're done maybe at the end of  the summer we'll talk I mean you  couldn't it would take forever so you  just start slowly but what you do as an  owner is every time you tackle something  or you have someone tackle something  start documenting be curious any other  questions on this all right it gets  worse and this is not even that big  starting but it's not that bad  it looks bad but it's not crazy  right it gets you know it gets bad but  again you got a that's where at one  point when you're starting that level  you know when we get to that level what  you definitely need documentation  otherwise you are literally gonna make  your life complete health but same thing  you know you've got read/write for any  to me mm here you've got all these  multi-touch boxes right but they're  talking Ethernet right  they don't even actually sell they used  to not even sell their own hubs or  switches you would just put a  third-party switching through no wood  didn't make any later on a marketing  company you just don't bother with stuff  like that they're like just buy a switch  it's gonna work right and so you would  actually just buy a switch you can see  they've got a black box a is transponder  and fa-50 heading sensor really popular  right if your radar doesn't work you're  going to be able  well why is my radar overlay not working  but my radar works on the radar page Oh  probably in your heading sensor failed  this is a device you know if you got  junction boxes it's a way of aggregating  all this information translating that  information from you might have some  some devices there most devices will do  the translation between enemy a 2002  Ethernet to share to other devices on  the chart plotter itself right they're  gonna actually go okay I've got all this  information like for example a really  cool one is Vesper they're actually the  one I was talking about the AIS they'll  actually take all information be it zero  one eight three enemy in two thousand  they're gonna aggravate it and then  they're gonna take it and then if you  want you can actually see on your phone  it's a portal to not only things that  are AIS but all data on your boat like  depth wind speed speed on ground course  on ground sea tab whatever it is sort of  data and you're seeing all this data  right on your phone so it's a portal to  all your navigational or kind of data  you're not going to see a radar image  you're not going to see a chart plotter  but you're gonna see data on there all  right we're gonna take a small break and  then we're going to dive into electrical  troubleshooting all right
