The Interface Settings Page allows you to choose from 
different input/output serial data formats. This feature is 
used when connecting to external  NMEA devices, a DGPS 
beacon receiver, a personal computer, etc. Effective use of 
this feature requires a working knowledge of these formats:
Garmin - The proprietary format used to exchange 
waypoint, track, and map data with a PC.
Garmin DGPS - Allows DGPS input using a Garmin 
beacon receiver and a standard RTCM SC-104 and DGPS 
tuning.
NMEA In/Out - Supports the input and output of stan-
dard NMEA 0183 version 3.0 data.
Text Out - Allows ASCII text output of location and veloc-
ity information without input capabilities.
RTCM In - Allows DGPS input using a standard 
RTCM SC-104 format without output capabilities.
RTCM In/NMEA Out- Allows DGPS input using a 
standard RTCM SC-104 format and supports the output of 
standard NMEA 0183 version 3.0 data. 
RTCM In/Text Out- Allows DGPS input using a standard 
RTCM SC-104 format and simple ASCII text output of 
location and velocity information. 
None - Provides no interfacing capabilities.
If ‘Garmin DGPS’ or ‘RTCM in/NMEA Out’ format is 
selected, additional fi elds are provided to control a Garmin 
differential  beacon receiver (e.g. GBR 21 & GBR 23) 
directly from your unit. Tuning is automatic with ‘Scan’ 
or you can enter the beacon frequency and bit rate when 
you select ‘User’ from the Beacon list to manually tune the 
receiver. Refer to the beacon receiver instructions.
To select a serial data format:
1.   Highlight the Serial Data Format fi eld and then press 
in on the THUMB STICK to display options. 
2.   Highlight an option and then press in on the THUMB
STICK to activate it.
