Garmin GPS III Pilot - Manual (Page 95)

Interface Settings
Format lets you control the input/output format used when connecting your GPS III Pilot
to external NMEA devices, a DGPS beacon receiver, or a personal computer, etc. Five for-
mat settings are available:
• Aviation In — allows the GPS III Pilot to communicate with a GARMIN
panel-mounted GPS. Flight plans (or GOTO destinations) selected on the
panel-mounted GPS will also appear on the GPS III Pilot.
• GARMIN — the proprietary format used to exchange waypoint, route, track log
data with a PC or with another GPS III Pilot.
• NMEA — supports the input/output of standard NMEA 0183 version 2.0 data.
• None — provides no interfacing capabilities.
• RTCM/NMEA — allows Differential GPS (DGPS) input using a standard RTCM
format and also provides NMEA 0183 version 2.0 output.
• RTCM In — allows DGPS input using a standard RTCM format, without any
output capabilities.
To select an input/output format:
1. Highlight the ‘Format’ field and press ENTER.
2. Select the desired setting and press ENTER.
3. If the ‘GARMIN’ format is selected, highlight the ‘Transfer Mode’ field and press ENTER. Select
the desired setting and press ENTER. The ‘Transfer Mode’ field allows you to specify what infor-
mation to request or send to a second GPS III Pilot. The ‘Host’ setting lets you control all data
transfer functions from the second GPS III Pilot or from a PC.
4. If an ‘RTCM’ format is selected, additional fields are provided to control a GARMIN differential
beacon receiver (such as GARMIN’s GBR 21) directly from your GPS III Pilot. You can enter the
beacon frequency and bit rate on the GPS III Pilot and the information will be used to tune the
beacon receiver. For more information, refer to the owner’s manual for your beaon receiver.
The ‘GARMIN’ option allows
the GPS III Pilot to exchange
data with a PC or another
GPS III Pilot. Use this setting
to perform database updates.
When transferring data to/
from another unit, select the
type of data and whether to
‘request’ it from or ‘send’ it to
the other unit.
