Appendix A. CRBasic Programming Instructions GPS Used with a GPS device to keep the CR3000 clock correct or provide other information from the GPS such as location and speed. Proper operation of this instruction may require a factory upgrade of on‐board memory. Syntax GPS(GPS_Array, ComPort, TimeOffsetSec, MaxErrorMsec, NMEA_Sentences) Note To change from the GPS default baud rate of 38400, specify the new baud rate in the SerialOpen() instruction. HydraProbe Reads the Stevens Vitel SDI‐12 Hydra Probe sensor. Syntax HydraProbe(Dest, SourceVolts, ProbeType, SoilType) LI7200 Communicates with the LI7200 open path CO2 and H2O sensor. Syntax LI7200(Dest, Reps, SDMAddress, Command) LI7700 Communicates with the LI7700 open path CO2 and H2O sensor. Syntax LI7200(Dest, Reps, SDMAddress, Command) TGA Measures a TGA100A trace‐gas analyzer system. Syntax TGA(Dest, SDMAddress, DataList, ScanMode) Therm107 Measures a Campbell Scientific 107 thermistor. Syntax Therm107(Dest, Reps, SEChan, Vx/ExChan, SettlingTime, Integ, Mult, Offset) Therm108 Measures a Campbell Scientific 108 thermistor. Syntax Therm108(Dest, Reps, SEChan, Vx/ExChan, SettlingTime, Integ, Mult, Offset) Therm109 Measures a Campbell Scientific 109 thermistor. Syntax Therm109(Dest, Reps, SEChan, Vx/ExChan, SettlingTime, Integ, Mult, Offset) 491
