vehicle. Other grounds may provide acceptable performance. Youshould minimize the overall length of the ground wire for bestperformance.2.3.6 Connecting the DGPS MAX To External DevicesThe DGPS MAX operates at the RS-232C interface level tocommunicate with external data loggers, navigation systems, andother devices. It features two data connectors on the rear panel,labeled ‘MAIN’ and ‘AUX’ to transmit and receive data (refer toAppendix B Interface Information).MAIN is the primary interface port for differentially corrected GPS data.The AUX port is a secondary port designed for input of external RTCMcorrection data. In the case that an external differential source isrequired, you may configure the DGPS MAX using the menu system toaccept the external correction data through the AUX port.Both data ports are located at the back panel of the DGPS MAX andare a DB9 socket connector. Table 2-2 and Table 2-3 provide pinassignmentinformation for the DGPS MAX MAIN and AUX serial portsrespectively.Table 2-2 MAIN Pin-out, RS-232C Interface LevelPin # Signal Description2 TXD DGPS MAX NMEA 0183 and binary output3 RXD DGPS MAX NMEA 0183 and binary input5 Sig.
