14 GPS NMEA-FORMATTED SERIAL DATA
CONNECTION
To obtain GPS NMEA-formatted serial data from the radio, use of the Full-Data I/O Option Cable
1000022242-0001 is recommended. Follow this procedure to complete the GPS NMEA-formatted serial
data connections if using the Full-Data I/O Option Cable:
1.
Connect the Full-Data I/O Option Cable’s 44-pin male connector to the radio’s 44-pin female
connector. Tighten the two jackscrews with a small flathead screwdriver. Do not over-tighten.
2.
Connect the cable’s DB-9 female connector labeled “GPS” to the computer’s serial port DB-9 male
connector — either directly or with an optional MAMROS0055 serial cable — and tighten the screws
until firm. Route the cabling as required.
3.
Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio.
If the Full-Data I/O 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 4, 20 and 34). See Table 13-1 for additional
information.
Industry software to process GPS information through this interface is not supported by
M/A-COM.
