Vesper not talking over seatalk ng

[weisbergj]

Hi Chuck,

I have hooked a Vesper 8000 AIS to my system via SeaTalk ng, using a DeviceNet adapter cable, but the GPM-400/G120 does not see the unit or receive AIS data.

I have tried connecting the vesper both to the Seatalkng hub using a spur cable, and using a t connector with terminator. In both cases, I was able to get the compact keyboard to connect, but not the AIS. I also checked the system diagnostics to see what ng devices were connected, but only the keyboard is seen.

I've updated the firmware on the GPM 400 to 4.66, the firmware in the vesper, rebooted everything, but nothing seems to work.

Any suggestions would be much appreciated.
