SERVER
Note c: If the NMEA instrument has only one output cable, put a ”bridge” cable on the
Server between pins 11 (INPUT B) and 12 (0V GND).
2.8 Connecting a NMEA instrument OUT from Server
Products receiving NMEA, for example:
Plotter, radar, Maxi repeaters, POWER Navigate.
Again you must know which 2 cables from your other NMEA instrument carry the
NMEA in signal. If you have trouble call the dealer you bought the NMEA instrument
from. He should know the wiring colour and will probably sell the ”plug set” which may
be required. We do not have this information.
Connect NMEA in signal from NMEA instrument to Server pin 3 (OUTPUT A). Connect
NMEA return signal from NMEA instrument to Server pin 4 (OUTPUT B). (For list of
NMEA transmit sentences, see 2.10.1.)
Connecting the power supply
1. Connect the red wire from the Server pin 1 (+12V) to +12V.
Connect the black wire from the Server pin 2 (0V) to 0V.
Protect the circuit with a 3 Amp fuse/circuit breaker on the 12V side.
