Provides for tuning of the beacon receiver directly from the GPS V.NMEA Out—Supports output of standard NMEA 0183 version 3.0 data. No input.Text Out—Allows ASCII text output of location and velocity information. No input.RTCM In—Provides DGPS input using a standard RTCM SC-104 format. No output.RTCM In/NMEA Out—Allows DGPS input using a standard RTCM SC-104 formatand supports the output of standard NMEA 0183 version 3.0 data.RTCM In/Text Out—Allows DGPS input using a standard RTCM SC-104 formatand supports the output of simple ASCII text information for location and velocity.None—Provides no interfacing capabilities.To change an Interface Setup Page feature:1.
