Interface Setup
The GPS II’s interface page lets you specify the formats for connecting external
devices. There are six options: GRMN/GRMN, None/None, RTCM/None,RTCM/NMEA,
NMEA/NMEA, and None/NMEA. Each option lists the input format first, followed by
the output format.
To select I/O format:
1. Highlight the I/O field, and press ENTER.
2. Select the desired setting, and press ENTER.
The GRMN/GRMN setting is a proprietary format that lets you exchange informa-
tion such as waypoints, routes, and track logs between two GARMIN GPS devices or a
GARMIN GPS and a PC. There are eight data transfer options: send alm, send wpt,
send trk, send rte, request alm, request wpt, request trk, request rte.
To select a transfer option:
1. Highlight ‘HOST’, and press ENTER.
2. Select a desired setting, and press ENTER.
To disable all interfacing capabilities, select the None/None setting. If you want to
output NMEA 0183 data without any differential input capability, select ‘None/NMEA.’
During data transfer, the num-
ber of packets being exchanged
will be displayed on screen.
