Comm (Communications) Tab

The Communications tab controls the input/output format used

when connecting your GPSMAP 192C to external NMEA devices,

such as an external Sonar Module, a DGPS beacon receiver, a

personal computer, or another Garmin unit.

NOTE: If a DGPS receiver is used, WAAS capability is

automatically turned to Off. See page 99 for wiring and NMEA

version information.

The unit supports two input/output ports.

Port 1

• Garmin Data Transfer—is the proprietary format used

to upload/download MapSource data, exchange waypoint,

route, track, almanac, and proximity data with a PC or

another Garmin unit. When you select Garmin Data Transfer,

there are 11 Transfer Modes to choose from: Host, Request

Almanac, Request Proximity, Request Routes, Request

Tracks, Request Waypoints, Send Almanac, Send Proximity,

Send Routes, Send Tracks, and Send Waypoints.
