I have installed a new VHF radio
Standard Horizon GX2000 and want to connect it to my AIS
GME AIST120 via NMEA1087. But no data appear on the GX2000. The Baud is configured to 38.400 Baud.
GX2000 <----------- AIST120
Yellow (RX+) <-----Brown (TX+)
White (RX-) <------ Blue (TX-)
The proAIS2 diagnostic show that the right information is transmitted. The AIS
is also connected to my Plotter but via NMEA2000, this works fine.
If I connect a voltmeter to the Yellow and White it fluctuate between 0 and 2,2 Volt. I take this as some thing is transmitted.
Please suggest possible solutions
