The power cable has three wires; red, white, and black. Red is the
positive
lead, black is negative or
ground. Attach the in-line fuse holder
to the red lead as close to the
power
source as possible. For example,
if you have to extend the
power cable to the battery or power buss,
attach the fuse holder to the
battery
or power
buss. This will protect
both the unit and the
power
cable in the event of a short. The white
wire is for a NMEA interface. The Z-9500 sends data for an autopilot
or other electronic
navigation devices through this wire. If the white
wire is not
used, tape the end so that it cannot short.
To connect a device to the Z-9500's NMEA output, attach a shielded,
twisted
pair cable from the autopilot's NMEA intput
to the white wire on
the Z-9500's
power
cable. Solder the
ground conductor of the twisted
pair and the shield to the black wire on the power cable. Do not
connect the shield to the autopilot. See the other device's manual for
more
wiring instructions.
The ELC-1 supplied
with the 2-9500 has an
external ground lug. This is
useful if you have noise problems or if you're in an area with low
signals. See page 103 for
wiring instructions.
