So I have a very simple N2K network set up on my boat. It's a GPS
and a 3-function transducer hooked up to an Actisense NGW-1 which converts to NMEA 0183
and plugs into a computer. Everything was working fine but the GPS
would occasionally cut in and out. It never lost
signal for more than a second or two so I had just chalked it up to interference
or something. Then one day the computer stopped getting all signal from the N2K network. The Actisense would turn on but the LEDs would blink in the pattern that meant it wasn't getting signal from either side. I was still able to use the Actisense software
on the computer which would detect the NGW-1 and even send signals to it (which would make the 0183 LED blink normally for a few seconds) but nothing else.
All of that led me to think something was wrong with the NGW-1 so I emailed Actisense and one of the first things they asked me to check was that the N2K network was getting power and functioning. I turned everything on now the NGW-1 doesn't light up at all, like it's not getting power. I put a clamp meter on the N2K power cable where I could isolate one wire and it seems to be getting power there but I'm not sure how to check that there's power anywhere else. I also only have the computer as a display so I don't know how I could check that the rest of the network is working.
This is getting pretty frustrating so any help would be greatly appreciated! Thanks!
