Interface SettingsFormat lets you control the input/output format used when connecting your GPS III Pilotto 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 GARMINpanel-mounted GPS. Flight plans (or GOTO destinations) selected on thepanel-mounted GPS will also appear on the GPS III Pilot.• GARMIN — the proprietary format used to exchange waypoint, route, track logdata 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 RTCMformat and also provides NMEA 0183 version 2.0 output.• RTCM In — allows DGPS input using a standard RTCM format, without anyoutput 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. Selectthe 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 datatransfer 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 differentialbeacon receiver (such as GARMIN’s GBR 21) directly from your GPS III Pilot. You can enter thebeacon frequency and bit rate on the GPS III Pilot and the information will be used to tune thebeacon receiver. For more information, refer to the owner’s manual for your beaon receiver.The ‘GARMIN’ option allowsthe GPS III Pilot to exchangedata with a PC or anotherGPS III Pilot. Use this settingto perform database updates.When transferring data to/from another unit, select thetype of data and whether to‘request’ it from or ‘send’ it tothe other unit.87REFERENCESetup: Interface
