Garmin GPSMAP 175 - Manual (Page 73)

The Input/Output submenu lets you control interface settings for
connecting external NMEA devices, a DGPS receiver or a personal computer.
The ‘Input/Output Format’ field, at the top of the page, lets you specify one of
seven interface options:
Data Transfer is a proprietary interface that allows you to exchange data
such as waypoints, routes and track logs between GPSMAP units or a
GARMIN
PCmate PC-Kit.
No In/NMEA Out provides navigation information to a compatible NMEA
device such as an autopilot or radar. NMEA 0180, 0182, 0183 v.1.5 and
0183 v.2.0 output options are available. (See Appendix B for additional
NMEA sentence information.)
No In/No Out provides no interfacing capabilities.
RTCM In/NMEA Out allows DGPS beacon receiver input and also
provides selectable NMEA output.
RTCM In/No Out allows DGPS beacon receiver input, with no output
capabilities.
NMEA In/No Out allows input from a NMEA compatible external device,
such as a Yeoman© Plotter, with no output capabilities.
NMEA In/NMEA Out provides the same input capabilities as NMEA IN,
with selectable NMEA output.
When the ‘Data Transfer’ option is selected, you’ll need to specify what
information to request or send to the remote unit through the Transfer Mode
field. The ‘slave’ setting lets you control all data transfer from the “external”
GPS receiver, or PC while the other settings request or send specific data from
the primary unit.
