NMEA Cable Connections
NMEA is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA inter-
face on the IntelliMap 502C and receive positioning information. The
IntelliMap 502C can exchange information with any device that trans-
mits or receives NMEA 0183 data, however, a communications cable is
not available for the unit at press time.
If you need to create a NMEA 0183 connection, consult customer serv-
ice. Service contact information is located in the back of this manual.
See the diagram on the preceding page for general wiring connections.
Read your other product’s owner’s manual for more wiring information.
NMEA Wiring
To exchange NMEA data, the IntelliMap 502C has one NMEA 0183
version 2.0 communication port. Com port one (Com-1) can be used to
receive NMEA format GPS data. The com port can also transmit NMEA
format GPS data to another device.
A data cable should contain three wires. 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 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 or Portable
You can install the IntelliMap 502C on the top of a dash with the sup-
plied gimbal bracket. It can also be mounted on a portable power supply.
If you use the supplied bracket, you may be interested in an 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. R-A-M offers permanent
mounts and temporary mounts suitable for many vehicle types. See your
