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's late.
