[CA] [CA11] Matrix GX2100 to eS Series 128 NMEA 0183 wiring

[JimF]

PROBLEM: AIS targets are not displaying on the chart. I'm not sure the wiring is correct for port 1 and port 2 between the gx2100 and the eS128. I spoke to Standard Horizon and they advised:

-The 2100 receives GPS data on the Blue wire. This is an input to the radio. Connect the TX(+), Data Out wire of the GPS.

-The Green wire should be attached to TX (-), RX (-) and or ground. Connect this to the black ground wire or (-) wires on the GPS.

-The output of DSC will occur on the Gray wire at 4800 speed. Output leaving the radio. Connect this to the RX(+), Data In GPS wire.

-The output of AIS will occur on the Brown wire at 38400. Output leaving the radio. Connect to a different RX(+) than the one used above. The GPS needs to be setup for NMEA 0183 (38400 baud rate) in this installation. This must be a different input port than the one used for DSC.


Here's how the eS128 is currently wired:

GX2100 to eS128
Blue (TX+) to Yellow Receive + Port 1 4800 Baud
Green (TX-) to Brown Output - Port 1 4800 Baud
Green (TX-) to Green Input - Port 1 4800 Baud
Gray (Output) to White Receive + Port 1 4800 Baud
Brown (RX+) to Orange/White Receive + Port 2 38400 Baud

Is this wiring correct? Other than turning AIS on the eS128 and configuring ports 1 and 2 to the correct baud rates, are there other options that must be set to specific values to display targets on screen?

Thanks for the assistance from this group.
