Input/Output Submenu
The Input/Output submenu lets you control interface settings for connecting
external NMEA devices, a DGPS receiver or a personal computer. The
‘Input/Output Format’ field, at the top of the page, lets you specify one of seven
interface formats:
Data Transfer is a proprietary interface that allows you to exchange data such as way-
points, routes and track logs between GPSMAP units or a GARMIN PC kit.
No In/NMEA Out provides navigation information to a compatible NMEA device such
as an autopilot or radar. NMEA 0180, 0182, 0183 v.1.5 and 0183 v.2.0 output options
are available. See Appendix A for additional NMEA sentence information.
No In/No Out provides no interfacing capabilities.
RTCM In/NMEA Out allows DGPS beacon receiver input and also provides selectable
NMEA output.
RTCM In/No Out allows DGPS beacon receiver input, with no output capabilities.
NMEA In/No Out allows input from a NMEA compatible external device, such as a
Yeoman© Plotter, with no output capabilities.
NMEA In/NMEA Out provides the same input capabilities as NMEA IN, with selec-
table NMEA output.
When the ‘Data Transfer’ option is selected, you’ll need to specify what informa-
tion to request or send to the remote unit through the Transfer Mode field. The
‘slave’ setting lets you control all data transfer from the ‘external’ GPS receiver, or
PC while the other settings request or send specific data from the primary unit.
