Seatalk is working. There's a GPS 130 that's feeding the network, data shows up and works on both i70's, and the a65 sees it when the internal gps is turned off. These are connected to a 5 port adapter block, which feeds a blue network cable over to an itc5, which gets wind, and that works. The Actisense NGW-1 has a stNG-2000 adapter cable and is plugged into the white (spur) plug on the itc5, and the 0183 end is cabled out to a Standard GX2150. The blue from the itc5 goes to a T that has a (white) DST 800, and that works. Network is terminated properly.
Network works, AP works, compass and inputs work. GX2150 does not get GPS, and Actisense starts properly, negotiates serial speed as it should then does the "housekeeping flashing" as it should when no data is there.
Substituting a T for the ITC 5 does not change this, BUT, unplugging the white from the itc5 did a couple of times today cause it to "wake up" and suddenly there's data. Data does update as the boat swings on the mooring, and the data matches whats on the i70s. Turn off the network, turn it back on and it's right away back to non operational.
We had an unforeseen "brownout" of biblical proportions (don't ask) that fried a NoLand RS11, and this started. The only things that have not been removed are the two 5-pin adapters. I'm going to collapse it down as close to the GPS and the Actisense, and I suspect that it'll work as expected. This is not a new installation, it's been working just fine for a number of years, but something is not happy.
