Default Stumped on AIS connection!

As part of my overall instrument suite, I am attempting to connect a West Marine AIS 1000 class B to my Raymarine C-120W. According to the indicators on the AIS, everything is working...but no AIS targets. I'm not at all sure I have the signals correct to the display. The unit is connected via an orange & black pair (on the AIS) to the 38.4k port on the display, which is also orn/gry on the display and labeled +/- input.

This is getting fairly confusing. Question is, has anyone done the same install on same or similar units? Does the C-120 have to be specially configured, i.e, AIS overlay?? configure port to 38.4? etc, etc.

I'll call Ray in the AM...it's late.
Tnx,

Is the AIS icon lit up on the C-series screen? If it is then everything is wired correctly. You probably just need to go into the presentation settings & turn the AIS overlay on.

NMEA Input cable color are green ( Ve in minus) and white( Ve in plus).
Assuming that it is fine, please check general NMEA0183 setting, it has to be switched to 38400.
Pls refer to manual Chapter 12 ( System Integration Setup -- NMEA Port Setting )
Also recommandable is to upgrade the firmware to V5.04 as faulty calculation to TCPA is corrected, if not done.
If you follow Chapter 11 Operation Manual it should work. I have a E120 with AIS which is simular to C120.
