    Figure 3-1. CR1000 to GPS16X-HVS connection Using with an A300 In 2014, Garmin changed the pulse-per-second (PPS) output of the GPS16X-HVS from 5 V to 3 V. Units with a serial number 1A4189318 or greater have a PPS output of 0 to 3 V. For those units, an A300 is needed to connect the PPS output to a CR800-series, CR1000, or CR3000 datalogger.

    The GPS16X-HVS has several data formats available. The GPS16X-HVS is configured to output the NMEA $GPGGA and $GPRMC 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. See Appendix A, Changing GPS16X-HVS Settings , for details.

    Fix each subsystem before testing others. Testing and Evaluating Serial Communications Test the GPS16X-HVS for proper operation including the baud rate and output string. Use a computer, terminal emulator software, a serial port (RS-232), and a 9-pin to pigtail cable (SC110/sockets). The computer and serial port can be the same as used to communicate with the datalogger.

    GPS16X-HVS GPS Receiver NMEAStrings Variable Populated, but Clock Not Setting Look at the GPSReady variable. It will increment from 0 to 10 when the datalogger has received good GPRMC strings and a synchronized PPS signal. Once GPSReady reaches 10, the datalogger will begin to use GPS time for clock setting.

    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 cannot be less than 2 seconds when the PPS signal is not used.
