34ReferenceSystem Setup‘Interface’ Settings PageSerial Data Format OptionsSerial Data Format Page for aGARMIN Beacon Receiver.When set for ‘Scan’ the unitwill stop at the first receivedbeacon signal. When set for‘User’ you must enter thefrequency of the desired beaconand adjust the bit rate. The‘Status’ field provides advisoryinformation about the beaconstatus and a message willappear if the beacon signal isnot being received.(See Appendix C)Interface SettingsThe ‘Interface’ Settings Page allows you to choose fromseven different input/output serial data formats, or none at all.This feature is used when connecting your eMap unit to externalNMEA devices, DGPS beacon receiver, a personal computer, etc.It is necessary to have a working knowledge of these applica-tions. Below is a description of each format:GARMIN - the proprietary format used to exchangewaypoint, track, and map data with a PC.GARMIN DGPS - Allows DGPS input using aGARMIN beacon receiver and a standard RTCMSC-104 format and DGPS tuning.NMEA - supports the input and output of standardNMEA 0183 version 2.3 data.Text Out - allows simple ASCII text output oflocation and velocity information, without anyinput capabilities.RTCM In - allows DGPS input using a standardRTCM SC-104 format without any output capabilities.RTCM In/NMEA Out - allows DGPS input using astandard RTCM SC-104 format and supports theoutput of standard NMEA 0183 version 2.3 data.RTCM In/Text Out - allows DGPS input using astandard RTCM SC-104 format and simple ASCII textoutput of location and velocity information.None - Provides no interfacing capabilities.Select the desired Serial data Format from the list. If‘GARMIN DGPS’ or ‘RTCM In/NMEA Out’ format isselected, additional fields are provided to control aGARMIN differential beacon receiver (e.g. GBR 21) directlyfrom your eMap unit. Tuning is automatic with ‘Scan’ oryou can enter the beacon frequency and bit rate when youselect ‘User’ from the Beacon list to manually tune thereceiver. For more information, refer to instructionssupplied with the beacon receiver.When selecting, ‘Text Out’, ‘RCTM In’, and ‘RCTM In/Text Out’ formats, a Baud field with a list of options willdisplay.
