Interface Settings (Input/Output)
The ‘INTERFACE’ Settings Page allows you to use your Geko 301 with external NMEA
devices, DGPS beacon receivers, a personal computer, etc. You can choose from seven differ-
ent input/output serial data formats, or none at all. Below is a description of each format:
• GARMIN - default setting that allows you to update software and communicate with
MapSource (transfer waypoints, routes, and tracks).
• GARMIN DGPS - allows DGPS input using a Garmin beacon receiver and a standard
RTCM SC-104 format and DGPS tuning.
• NMEA - supports the output of standard NMEA 0183 version 3.0 data.
• TEXT OUT - supports the output of ASCII text location and velocity information.
• RTCM IN - allows DGPS input using a standard RTCM SC-104 format without any
output capabilities.
• RTCM/TEXT- 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.
