Wiring
A 2m (6.5') cable with attached connector is supplied with the
AIS
WatchMate
. You may extend this cable as necessary. It is
recommended that any splices made in the cable be done in a
weather tight area to prevent corrosion and failed connections.
Consult a marine electronics technician if you have any difficulties
or concerns about installation.
Insert the connector into the back of the display firmly and
completely, fully engaging the locking ring to ensure a watertight
seal.
Brown
12 volts (10-16) DC positive
(+).
Ensure there is a
circuit breaker or fuse rated at 2A in the positive power
connection. It is recommended to add a fuse if
necessary.
Blue
12 volts DC negative (-)
.
Red
Serial port 1 ground.
If you are connecting this port to
a computer, use a female 9 pin DB9 connector and
connect this wire to pin 5. If you are connecting this
port to a NMEA device such as a GPS or chart plotter,
connect this wire to the ground wire on your device. If
your GPS or chart plotter has NMEA +/- (or A/B),
connect this wire to the DC ground wire, not the
NMEA-negative or NMEA B.
Pink
Serial port 1 data in.
If you are connecting this port to
a computer, connect this wire to pin 3 on a female DB9
connector. Otherwise, connect this to the data output on
your AIS or GPS receiver or transponder.
