And when both engines are off, it will switch off as well.Raymarine SeaTalk 1 to SeaTalk ng & NMEA 2000 I guess it is just more convenient to use the dual power node because it means that whenever one of the engine keys is turned on, the network will be active and everything will work. So if you can add a switch to that 12 V accessories circuit connection, then that would be better.

However, there is nothing much really wrong with your current setup, except that its best to have the network power source on a switched source of power. This would work well with a dual engine setup as you can appreciate. If one turns off, it automatically changes to use the other. Tyler is possibly referrring to a dual power node - its just a special network power node that can connect to 2 power sources, it then selects one of those to use. If that is all the devices you have attached to your network, then the normal situation would be to get network power from one of the engine harness power connectors - but that of course would mean that the network (and thus the gauges and antenna) would only get power if that particular engine's key is turned on as you know. So, let me understand - the things below you listed are ALL that is on your network:

Should I look further for this "thing" that splits the network ? Anyone know what its called?.

Should I leave the network power on the accessories, which means the Suzuki gauges are powered up but have not input data when the key is off?.

Should I put the network only on the Suzuki harness power drops, in which case, they key needs to be on to get the GPS position (not ideal)?.

I should give him a call back but thought I would see how others have rigged their systems up. He mentioned that to maintain the one network I could consider splitting the NMEA network with a 'thing' that would allow two independent power supplies to each side of the network (one from general accessories for the Garmin gear and one for the Suzuki gear) but still allows the data to flow through this 'thing' - keeping all functions on the one network. Tyler at IMS mentioned that the Suzuki gauges should be powered from the power drops in the main engine harness to ensure power to gauges comes from the key.

At the moment, the power supply for the network comes from an 12V accessories circuit. The C10 gauges are on the NMEA network, along with my Garmin GPS antenna and Suzuki engine interface cables. I've just installed DF200APX's and 2 C10 gauges in my old Formula 233.
