Section 11. Programming Resource Library Either the output array or the input array or both can be specified as 0 meaning no data flow in the corresponding direction. The HostAddr parameter is the PakBus Address of the master of the network, the destination of the sensor’s data. The RouterAddr is the PakBus Address of a router if the distance is too far to reach the Host directly. Typically a router will not be present so this address with be identical to the HostAddr. If it is 0, then the system will automatically find a neighbor it can route through. All communication with the host datalogger (CR800, CR1000 or CR3000) takes place through the SendGetData() instruction. When SendGetData() is included in the CR200 CRBASIC program, the CR200 calls the host approximately every 60 seconds with a random time into interval setting to establish the first connection. At first connection, the CR200 sends a variable array to the host, retrieves a variable array from the host, and retrieves a call time slot and a clock synchronization setting. Thereafter, the CR200 calls at the appointed time slot. 11.2 Radio Power Minimization Power settings on the CR200(X) radio are used to optimize the current drain of the system. The radio can be set to be always on, power up once a second or every 8 seconds, or be turned on by the CR200(X) program. When the status table field RF_ForceOn is set true under program control, the radio is on only as long as necessary for data transmission and receiving. This provides the lowest power usage by the radio. RF_ForceOn can be controlled with table access syntax (SetStatus(Rf_ForceOn,1) for example) or it is controlled by the instruction SendGetData() as shown in the following example p. 111. A CR1000 datalogger with PakBus address 2 and a RF401 radio is configured as the “master”. It sends a Network() command every 5 minutes to synchronize the radio transmission. A CR206X datalogger with PakBus address 3 measures its sensors every 15 minutes and runs a countdown using TimeUntilTransmit(). When the countdown reaches zero, the CR206X powers its radio and transmits data to the CR1000 as well as receiving the CR1000 battery voltage. The radio address and hop sequence of the CR206X must match the same settings in the RF401. 110
