Power Connections
This unit operates from a 12-volt battery system. For the best results,
connect the power cable to the in-line fuse holder and attach it directly to
the battery. The power cable can be attached to an accessory or power
buss, however there could be problems with electrical interference using
this method. Therefore, it’s better from a noise standpoint to attach the
power cable and fuse holder directly to a battery. If the cable is not long
enough, splice 16-gauge wire onto it.
The power connector has two cables attached to it. One cable has the
power and ground wires, the other is for the NMEA/DGPS interface. See
below for NMEA/DGPS wiring instructions. The power cable has two wires
- red and black. The black wire connects to the battery’s negative termi-
nal. The red wire is the positive wire. Connect it to the fuse holder supplied
with the unit. Connect the other end of the fuse holder to the positive side
of the battery. Make certain to attach the fuse holder directly to the bat-
tery. This will protect the both cable and the unit in case there is a short
circuit. Use a 6-amp fuse.
IMPORTANT!
Do not use this product without a 6-amp fuse connected to the power
cable! Failure to use a fuse will void your warranty.
