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.

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
