Now you are ready to connect your system to power, your NMEA 0183 loran/GPS (for
the Nav Repeater Mode) as well as interface it to other instruments on your boat, if
desired.
The power cable comes out of the junction box
and should be connected as
follows:
1. Connect the red wire to a +12V DC power source* which is fused (1 amp). There is
no internal fuse in the Sailcomp 103AC to protect it from current overloading.
5. Connect the
black wire
in the power cable to Ground.
There is also a cable coming out of the sensor with 4 wires. These wires connect the
Sailcomp to your NMEA 0183 loran or GPS so that you can activate the Nav Repeater
Mode and also connect to your other electronics that take NMEA 0183 so that they can
access the Sailcomp's heading data. The NMEA lines are used only for interfacing.
Note: Any wires that are not used should be clipped back and insulated from one
another.
The wiring is as follows:
Nav Repeater Mode:
brown
NMEA 0183 In(-)
blue
NMEA 0183 In(+)
NMEA 0183 output to instruments that require heading information:
green
NMEA 0183 Out(+)
orange
NMEA 0183 Out(-)
shield
not used(clipped back)
white
not used(clipped back)
red
not used(clipped back)
black
not used(clipped back)
1. The
brown and blue wires
are for connecting a NMEA 0183 loran or GPS to your
Sailcomp 103AC so that your Sailcomp 103AC doubles as a nav repeater. If these
wires are not used they should be clipped back and wrapped with electrical tape.
To connect the Sailcomp 103AC to your NMEA 0183 loran or GPS:
The configuration of the signal wiring will vary depending on the brand of loran or
GPS that you have and what parts come with it.
