MAIN MENU > SETUP TAB • GARMIN DGPS-used to connect the GPSMAP 196 with a Garmin DGPS beacon receiver. • NMEA In/NMEA Out-supports the input/output of standard NMEA 0183 version 2.3 data and sonar NMEA input support for the DPT, MTW, and VHW sentences. • Aviation In-the proprietary format used for connection to a Garmin panel-mounted GPS receiver. Allows the GPSMAP 196 to show a Goto or route selected on the panel-mounted GPS receiver. This eliminates the need to enter the destination on both units. • RTCM In-allows Differential GPS (DGPS) input using a standard RTCM format. • RTCM In/NMEA Out-allows Differential GPS (DGPS) input using a standard RTCM format and also provides NMEA 0183 version 2.3 output. • RTCM In/Text Out-allows Differential GPS (DGPS) input using a standard RTCM format and also outputs simple text data that includes, data, time, location, and velocity. • 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 196 using the Interface sub tab. 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. To have the unit automatically scan for a frequency: 1. With the unit set to GARMIN DGPS or RTCM In/NMEA Out, use the ROCKER to highlight the Beacon field, and press ENTER. 2. Highlight Scan, and press ENTER. The numbers in the Frequency field change as the unit scans from 284 kHz to 325 kHz, 200 bit rate, then 100, at 6-second intervals.
