GPS16X-HVS GPS Receiver 3. GPS Data The GPS16X-HVS has several data formats available. The GPS16X-HVS is configured to output the NMEA $GPGGA time and position string. It is possible to configure the GPS16X-HVS to output other NMEA strings including the $GPVTG track made good and ground speed string. -

Fix each subsystem before testing others. 5.1 GPS Setup and Function Test the GPS16X-HVS for proper operation including the baud rate and output string. Use a computer, terminal emulator software, a serial port (RS232), and a 9-pin to 9-pin serial cable. -

Pulse Per Second output. When the PPS signal is used to trigger the read data function (P15), the program table execution interval does not matter. Otherwise the timing between the GPS16X-HVS output and the datalogger read must be considered. Generally the execution interval can not be less than 2 seconds when the PPS signal is not used. -

This is a blank page. A.1.6 Troubleshooting The first step is to verify that it really does not work. With the GPS16X-HVS running and the datalogger program running, look at the input location for GPS Quality Number. This location will show a one when the GPS16X-HVS output is picked up by the datalogger. -
