I have a question about hooking up my GPS to my VHF. This seems like a question for Kerry but others might know. The VHF calls for NMEA (+) from GPS and NMEA (-) from GPS, but the GPS only has one NMEA in and one NMEA out, SOoooo do I just hook up the NMEA out from the GPS to the NMEA (+) of the VHF and leave the other blanked off ??
GPS has ..
pin 1. 10 - 40 volts DC
pin 2. Ground
pin 3. NMEA out
pin 4. NMEA in
pin 5. No connection
pin 6. no connection
pin 7. Alarm low
VHF has ..
pin 1. Not used
pin 2. NMEA out (+) (not used)
pin 3. not used
pin 4. NMEA in (+) ( from GPS)
pin 5. NMEA in (-) (from GPS)
pin 6. NMEA out (-) (ground, not used)
pin 7. NAVBUS
pin 8. NAVBUS
Help ;D
