nmea 0183 to RS232


I am interested in sending some nmea 0183 data to my computer. I believe that all I need to do is connect the correct nmea wires to the correct pins on a DB9 connector and then plug it into the serial port of my PC.

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 (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?
