10.3 GPS NMEA-FORMATTED DATA CONNECTION
To obtain GPS NMEA-formatted serial data from the radio, Option Cable 14002-0174-50 is required.
Follow this procedure to complete the GPS NMEA-formatted serial data connections:
1. Obtain Option Cable 14002-0174-50. Each “leg” of this cable is approximately 65 inches long (166
centimeters).
2. Connect the cable’s 44-pin D-subminiature (DB-44) male connector to the DB-44 female connector on
the rear panel of the radio. Tighten the two jackscrews with a small flathead screwdriver. Do not over-
tighten.
3. Connect the cable’s DB-9 female connector to the computer’s serial port DB-9 male connectoreither
directly or extended via cable CA-013671-020 (a 20-foot-long cable). Tighten the screws firmly, and
then route the cabling as required. If the computer is not equipped with a DB-9 serial port connector,
the use of a suitable adapter is required, such as USB-to-RS-232 Adapter Cable CN24741-0001.
4. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio.
If the Option Cable is not available, a 3-wire serial cable can be field-fabricated. On the
radio end, this cable must interface to the three GPS-related signals of the radio’s 44-pin
I/O Cable connector (pins 7, 31, and 32).
Industry software to process GPS information through this interface is not supported by Harris.
