Wiring examples
Refer to the Quick Start Guide for more wiring examples.
1 Analog/pulse terminal 1 example: wiring for a 213 mast head unit
2 Analog/pulse terminal 2 example: wiring for a speed (paddlewheel) sensor, and three congurable analog sensors
3 Alarms terminal example: wiring for an overboard button input with audible alarm
¼Note: Wire colors depend on your sensor. Refer to the documentation for your sensors.

Connect the power cable
If required, strip the ends of the supplied power cable to expose three insulated wires,
and separate the drain wire from the cable shield at one end.
At the power connector on the PCB, terminate the bare (drain) wire at the screen
pin (1). Terminate the black and red wires at the negative and positive pins (2 and 3
respectively).
Connect a 3 A fuse to the positive terminal of a 12 V or 24 V DC power supply.
Connect the red and black wires in the power cable to the positive and negative
terminals of the power supply, respectively. The bare (drain) wire is not used at the
power supply end of the cable, and should be cut.
Optional: Earth-ground wire (blue)
The blue wire in the power cable can be used to create a bleed path for excess
charge. Connect the blue wire to both the Earth-ground connection point (C) on the
PCB, and. a point on the hull in electrical contact with the water. If you don’t require
the blue wire, cut back both its ends.
