    1. Overview 2. Wiring FIGURE 1. GPS16-HVS GPS Receiver The GPS16-HVS is a complete GPS receiver manufactured by Garmin International, Inc. The GPS16-HVS has been configured by Campbell Scientific (Canada) Corp. (CSI) to work with CSI dataloggers. The CR1000, CR3000, CR800, and CR850 dataloggers use serial input instructions and string handling functions to read, parse and store GPS data.

    CR850 dataloggers. These dataloggers use several instructions to read GPS output, which is asynchronous serial data. As shipped from Campbell Scientific, the GPS receiver will output data once a second, 1200 baud, 8 data bits, no parity, and 1 stop bit. Only the GPGGA string is output. See Section 3 for details on the GPGGA string.

    Appendix A. CR23X/CR10X Programs A.1 Programming A.1.1 Program Execution Interval A.1.2 Reading GPS Data Program instruction 15 (P15) is used to read the NEMA $GPGGA string of time and position data. Each iteration of P15 can either read the numeric fields or read everything.
  • Page 15 Appendix A. CR23X/CR10X Programs P15 parameters 4, 5, and 10 are somewhat variable. When using a CR23X, parameter 4 can be set to 05, 06 or 07 depending on what control ports are used. A CR10X can use control ports 1 through 6. Wiring of the communication cable depends on the selection for parameter 4.
  • Page 16 NOTE Communication cable wiring for: CR23X/Example A-1 — PPS to C8, GPS transmit to C5. CR10X/Example A-2 — PPS to C8, GPS transmit to C2. A.1.3 Filters Filters can be used to make sure P15 reads the correct data string. Filters also ensure P15 starts to read the string at the beginning of the string.
  • Page 17 Appendix A. CR23X/CR10X Programs GPS quality number to verify your data. P15 will write to fifteen input locations if everything works correctly. If P15 fails to read the GPS data, only the first input location is written to. The GPS quality number will be unchanged.
