#Nmea 2000 network power full
I hit the test button on my trolling motor and it read full charge.
#Nmea 2000 network power pro
I have the Cabelas Pro Series 20 Amp 3 bank charger which is made by ProMariner (same as their 20amp 3 bank) If I recall it would auto jump to the level of the charge once it was done analyzing. It was on red for a few minutes then when to 2 LEDs then 3 another 5 minutes later It did its "analyzing" then showed a red led instead of the greens. In this case you would power your nmea network by connecting one of your LMS or LCX unit power cables marked NMEA Power to a switched power source. This diagram below shows the network bus configured for networking 2 LMS or LCX units to one GPS module. I unplugged the charger and let it sit for an hour or so. Mar 10, Note HDS Models would require a Power node to supply power to the Network Bus. The more I think about this the more I think it's the charger not showing the information correctly. Just has an overall "Charging & maintaining (1 red when empty 2,3,4,5 greens indicating charge level, 5 being full) and then switches to maintaining. All 3 banks are independent of each other but it does not tell me which battery is full and which is charging. It could very well be the charger not showing me the information correctly.
#Nmea 2000 network power install
Looking for a clean install in the gauge cluster or at least on the panel. I do need to install an inline power switch for the network. I have since disconnected the NMEA system and the charger seems to be acting correctly again.ĭid I mess anything up? Everything "seems" to be working ok. It was like this for a little while before I realized my mistake.

I had hooked it to the + and - of one of the batteries in the 24v system. Motor started and turned over just fine.Īfter a few days of this I realized I put the NMEA 2000 power to the wrong battery. All the while the cranking battery seemed just fine. I would plug in the charger, sometimes only after a few hours of being unplugged and it would read in the red (dead battery) and start charging the batteries. I noticed the charger would read the batteries as dead after only a day or two unplugged. I have a 24volt trolling motor system and the 12v starter battery with accessories. It is currently connected to two devices and power. Longer term I may also use the same device with a SIM to let me check on wind speed at the boat from anywhere (the closest wind station only reports data every hour).Ok so I installed a NMEA 2000 network on the boat. I plan on updating my DIY wind instrument to NMEA 2000 and also creating a NMEA 2000 to WiFi device so that we can see transducer data from phones or tablets.

I'm not an expert in it by any means, I just started playing around with dumping network traffic to learn the format. There is a reverse engineering of it here: NMEA 2000 is a closed protocol and only documented to those who pay for it and get devices certified. Raymarine doesn't seem to have supported this for too long, on my network my X5 autopilot prevents device negotiation from working properly (and I don't have any duplicate devices to really experiment with). That eliminates duplicate IDs, but I think a different PGN is used to get all devices on the network to identify themselves (it looks like it might be 59904). NMEA 2000 is build on J1939, and that is described pretty well here: Raymarine has an arbitration mechanism to handle multiple devices of the same type on NMEA 2000, but I don't know if this is a generic part of the spec or something proprietary. Two transducers outputting different data and intermixing longer messages (greater than one packet) would cause confusion but wouldn't "crash the bus". I asked because of "Message IDs must be unique on a single CAN bus, otherwise two nodes would continue transmission beyond the end of the arbitration field (ID) causing an error." Sounds like it's not an issue for N2k.ĭepth (PGN 128267) and speed messages (PGN 128259) are both one packet long, so there is no potential for confusion. It will either cause confusion with both reporting, or the system will continue to pay attention to the original one depending on the exact equipment used. ^^^ Is is likely that sticking two of the same type of node on the bus at the same time would crash the bus? Just wondering how critical it would be for the OP to switch out his old speed/depth/ before switching in the new.
