Comm (Communications) Tab

The Communications tab controls the input/output format used

when connecting your GPSMAP 188/188C Sounder to external

NMEA devices, 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 pages 98 and 99 for wiring and

NMEA version information.

The unit supports two input/output ports.

Port 1

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.

standard NMEA 0183 data, and sonar NMEA input support

for the DPT, MTW, and VHW sentences.

beacon receiver.

RTCM format, without any output capabilities.

• NMEA In/NMEA Out—supports the input/output of

standard NMEA 0183 data, and sonar NMEA support for the
