Damn, that's an old computer...most new ones don't have an RS-232 port on them. It sounds like you've got the right pin outs..since the NMEA Data out + should connect to the RS-232 RX Data pin (2 in a DB9 connector).

Don't forget to set the parity and stop bits properly. It should be 38400, 8 N 1. IIRC.

Is that correct?

Specifically, I want to connect a Standard Horizon GX2100 AIS VHF unit to my PC so that Seaclear can display the AIS data. The GX2100 manual states that the brown wire is NMEA HS (AIS) data and the green wire is NMEA common (ground). So all I need to do is connect the brown to DB9 pin 2 9 (received data) and the green to DB9 pin 5 (signal ground). The AIS data is at 38400 baud.

Is that correct or am I missing something?

Thanks,
Barry

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
