Garmin 201 Guida Utente

30

The Interface Page allows you to connect and use devices such as computers and dif-

ferential GPS (DGPS) beacon receivers to the Geko 201. 

The ‘Interface’ Settings Page allows you to use your Geko 201 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.
