12 Vdc negative is blue 12 Vdc positive is brown NMEA common: Yellow/green; NMEA Data: black NMEA via RS232: The standard RS-232 connector is a 25 conductor DB-25, although many units now use a 9 pin DE-9 which is different from a DB-9. Serial Port Connections Computer (DTE) Modem DB-25 DE-9 Signal Direction DB-25 2 3 Tx Data - 2 3 2 Rx Data - 3 4 7 Request to send - 4 5 8 Clear to send - 5 6 6 Data Set Ready - 6 7 5 signal ground 7 8 1 Data CarrierDetect - 8 20 4 Data Terminal Ready - 20 22 9 Ring Indicator - 22 For NMEA-0183 you are only concerned with Rx data, the signal ground (and possibly Tx Data, if we want the Navico to talk to the GPS) I believe the European standard is 4800 baud for this type of equipment. You may have to play with that a little. |
