Section 10. CRBASIC Programming Instructions 10.12 Satellite Systems Programming Instructions for GOES. Refer to satellite transmitter manuals available at www.campbellsci.com. 10.12.1 GOES The CR295 and CR295X dataloggers support communication through Campbell Scientific’s TX312 or HDR GOES satellite transmitters. The CR295(X) has an extra 9-pin serial port. The CR295 requires a special operating system and does not support radio telemetry or calculation of evapotranspiration and is not CE compliant. The CR295X has the same operating system and expanded capabilities as other CR200(X) series dataloggers. CRBASIC instructions used by the CR295(X) are: GOESData Sends data to a CSI GOES satellite data transmitter. Syntax GOESData (Dest, Table, TableOption, BufferControl, DataFormat) GOESGPS Stores GPS data from the satellite into two variable arrays. Syntax GOESGPS (GoesArray1(6), GoesArray2(7)) GOESSetup Programs the GOES transmitter for communication with the satellite. Syntax GOESSetup (ResultCode, PlatformID, MsgWindow, STChannel, STBaud, RChannel, RBaud, STInterval, STOffset, RInterval) GOESStatus Requests status and diagnostic information from a CSI GOES satellite transmitter. Syntax GOESStatus (Dest, StatusCommand) 108
Section 11. Programming Resource Library 11.1 Remote Sensor Interface The CR200(X) is frequently used as a remote sensor interface for a “Host” datalogger. Typically, the host datalogger and the sensor(s) (CR200(X)) will have programs that will enable the sensors to operate with the minimum quiescent current drain (110 µa). These programs synchronize the CR200(X) sensors so that they are reporting back the data in designated time slots. For applications demanding more frequent communication, the get/set variable instructions in the host datalogger can be used with CR200(X) sensors that are configured for higher current drain (250 µa for 8 second response; 20 ma for 1 second response). In the lowest power, synchronized mode, the CR200(X) always initiates communication. Except when it wakes up to send data, its radio is off, drawing no power. The host datalogger’s radio will be in a fully on position during the period of expected sensor communication, ready to receive and respond instantly. CRBASIC EXAMPLE 16. Const MT = 20 Const Port = 1 Const RouterAddr = 1 Const HostAddr = 1 Const NumVals = 8 Const Security = 0 Const NumControl = 4 Example Wireless Sensor Program For CR200(X) 'Measurement Time (secs) SDI-12 in this Case takes 20 seconds '1 = Radio, 2 = RS-232 To send out data 'the PakBus address of a router, in this Case the same as Host 'the PakBus address of the Host datalogger '8 Measurements 'use non zero If Host datalogger has Security set Public Measurements(NumVals) 'sensor values To send Public Control(NumControl) 'Control values returned from Host BeginProg Scan(1, sec) If TimeUntilTransmit(Port)=MT Then 'If it Is time To measure start Measurement 'applicable Measurements that take MT seconds inserted here EndIf NextScan EndProg TimeUntilTransmit(port) is a function that returns the number of seconds before it is time to communicate. It will use information retrieved from the datalogger to determine the time remaining before its communication time slot. SendGetData will output an array of measurements to the Host datalogger and retrieve a time slot, a clock setting, and optionally an array of data from the Host 109
