Garmin GPS 120 - Manual (Page 53)

The last GPS 120 setup page is the I/O setup
page. This page lets you specify the interfacing for­
mats for connecting external devices. There are six
I/O options available: GRMN/GRMN, None/None,
None/NMEA, NMEA/NMEA, RTCM/None, and
RTCM/NMEA.

lowed by the output format. To select I/O format:

mat that lets you exchange information such as
waypoints, routes and track logs between two com­
patible GARMIN GPS units or a PC with an option­
al GARMIN PC kit. During data transfer, the num­
ber of packets being exchanged will be displayed
on screen. To select a transfer option:

NMEA data to compatible external devices without
