NMEA/DGPS Wiring
To exchange NMEA or DGPS data, the IntelliMap 480 has one NMEA
0183 version 2.0 communication port. Com port one (Com-1) can be
used to receive NMEA format GPS data or DGPS data. The com port
can also transmit NMEA format GPS data to another device.
The three wires for the com port are combined with the two power
wires to form the power/data cable. Com-1 uses the yellow wire to
transmit, the orange wire to receive and the shield wire for signal
ground.
Com-1 wiring to receive DGPS position information
from a DGPS receiver.
Com-1 wiring to receive NMEA position information
from some other GPS receiver.
Com-1 wiring to transmit NMEA position information
to another NMEA-compatible device.
Mounting the Unit: Bracket, In-Dash or Portable
You can install the IntelliMap 480 on the top of a dash with the sup-
plied gimbal bracket. It can also be installed in the dash or mounted on
a portable power supply.
If you use the supplied bracket, you may be interested in the optional R-a-
M

bracket mounting system. This converts the unit's gimbal bracket to a
swivel mount, which can be used on the dash or overhead mounting posi-
tions. Installation instructions are supplied with the R-a-M mounting kits.
