6. Datalogger Programming
In CRBasic, the SDMCD16AC instruction is used to control the SDM-
CD16AC. Dataloggers that are programmed with CRBasic include our
CR800, CR850, CR1000, CR3000, and CR5000.
Edlog Instruction 104 is used by the CR23, 21X, and CR10(X) to control the SDM-CD16AC, and Edlog Instruction 29 is used by the CR7. SDM-CD16AC outputs that are to be controlled by the datalogger must have the toggle switch in the AUTO position.

SDMCD16AC
Syntax
SDMCD16AC (Source, Reps, SDMAddress)
Remarks
A port on an SDM-CD16AC is enabled/disabled (turned on or off) by sending a value to it using the SDMCD16AC instruction. A non-zero value will enable the port; a zero value disables it. The values to be sent to the CD16AC are held in the Source array.
The SDMCD16AC instruction has the following parameters:
Source: The Source parameter is an array which holds the values that will be sent to the SDM-CD16AC to enable/disable its ports. An SDM-CD16AC has 16 ports; therefore, the source array must be dimensioned to 16 times the number of Repetitions (the number of SDM-CD16AC devices to be controlled). As an example, with the array CDCtrl(32), the value held in
