Connectors
Power/Data Cable Wiring
A 2m (6.5') power/data 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.
Red
DC positive
(+) (12-24 volts).
Ensure there is a circuit breaker or fuse rated at
2A (max) in the positive power connection. It is recommended to add a fuse if
necessary. If you must extend the power connections, it is recommended to use
high quality pre-tinned marine grade wire which is
at least 16 AWG
(1.5mm
2
).
Black
DC negative (-)
.
Gray
NMEA data output positive.
Connect this wire to the NMEA data input (A or +)
on another device such as a chart plotter or radar.
Yellow
NMEA data output negative.
Connect this wire to the NMEA data input (B or
-
)
on another device such as a chart plotter or radar.
Green
NMEA data input positive.
Connect this wire to the NMEA data output (A or +)
on another device, such as a heading sensor.
White
NMEA data input negative.
Connect this wire to the NMEA data output (B or
-
)
on another device, such as a heading sensor.
Blue
External alarm.
When the alarm is triggered and the external alarm is enabled
this wire will have the input voltage (from the red wire) applied. You can use this
to provide power to an external buzzer, light or other signal device.
Maximum current is 150mA. If your device requires more current then an
external relay must be used.
Others
All other wires are not used. Leave them unconnected.
