• Text Out—allows the unit to output simple text data that
includes, data, time, location, and velocity. The Baud can be
set to 1200, 2400, 4800, or 9600.
• None—provides no interfacing capabilities.
If you select GARMIN DGPS or RTCM In/NMEA Out format,
you can control a differential beacon receiver directly from your
GPSMAP 296 using the Com 1 or Com 2 sub tabs. You can have
the unit automatically scan for the DGPS beacon signal, or you
can enter the beacon frequency and bit rate on the unit, and the
information is used to tune the beacon receiver. If you use a DGPS
receiver, WAAS capability is automatically turned off.
