Notes:

1.Power and ground wires require 18 AWG. All other wires require 22 AWG. Use 4-conductor, shielded wiring for runs over 30’ (9.1 m).

2.For runs over 30’ (9.1 m), the drain wire must be connected to the shielding of the extension run. Do not terminate the end of the shield drain wire.

3.The Orange wire must be pulled low (-) in order for the GSD 20 to power on.

Option 1: If the GSD 20 is wired to a circuit that is switched on the Red (+) wire, connect the Orange wire to ground. The GSD 20 and the GPSMAP 182/182C/192C/232 turns on/off when power is applied/removed to the Red wire.

Option 2: If the Red (+) wire is applied directly to a power source, install a switch between the Orange wire and ground. The GSD 20 turns on or off when ground is applied or removed to the Orange wire.
