Garmin 16-HVS GPS Receiver 3. GPS Data The Garmin16-HVS has several data formats available. The Garmin16-HVS is configured to output the NEMA $GPGGA time and position string. It is possible to configure the Garmin16-HVS to output other NEMA strings including the $GPVTG track made good and ground speed string. See Appendix D for details.

Garmin 16-HVS GPS Receiver 4.1.4 SerialClose The SerialClose instruction is used to close the serial port. Once closed, the SerialOpen command must be used before more data can be read. 4.2 Parsing and Data Storage Options The CR1000, CR3000, CR800, and CR850 can store data as a string or as a number.

Garmin 16-HVS GPS Receiver 5. Troubleshooting Testing and evaluation of serial communications is best done by reducing the whole system to small manageable systems. Usually some portions of the whole system are working. The first steps involve finding what is working.
Appendix A. CR23X/CR10X Programs A.1 Programming 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. When reading the numeric fields, such as time, latitude, longitude and elevation, P15 requires non-numeric delimiters between data points.
Page 14
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.
Appendix A. CR23X/CR10X Programs 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. To use a filter, follow P15 with instruction P63 (extended parameters). P63 is used to define the filter.
Appendix A. CR23X/CR10X Programs GPS fix. A better approach is to overwrite the GPS quality location with zero before executing P15. Use P30 to overwrite one input location. If the GPS time is used to set the datalogger clock, the GPS time must be parsed into three input locations: Hour, Minutes, Seconds.
Page 17
Appendix A. CR23X/CR10X Programs Additional input locations used in the example program are: 18) Orig_TM, Copy of original time 19) Int1, Place holder for math 20) Hours, formatted hours 21) Minutes, formatted minutes 22) Seconds, formatted seconds 23) remainder, place holder for math Before writing any datalogger code, it’s best to enter all the input locations needed.
