Garmin GPS 92 - Manual (Page 61)

Interface Setup
The ‘Interface’ setup page lets you specify the inter-
facing formats 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
six formats (input first followed by output):
• ‘GRMN/GRMN’ is a proprietary interface that
allows you to exchange data such as waypoints,
routes and track logs with another GPS 92 or with
a personal computer using a GARMIN PC kit.
• ‘NONE/NMEA?’ provides navigation information
to a compatible NMEA device such as a PC-based
moving map program, an ARGUS display or radar
display. NMEA 0180, 0182, 0183 v. 1.5 and 0183
v. 2.0 output options are available.
• ‘NMEA/NMEA?’ allows input from a NMEA
compatible device, with selectable NMEA output.
• ‘RTCM/NMEA?’ allows DGPS beacon receiver
input and also provides selectable NMEA output.
•‘RTCM/NONE?’ allows DGPS beacon receiver
input without output capabilities.
•‘NONE/NONE?’ provides no interfacing
capabilities.
