CD16AC (Source, Reps, SDMAddress)
The CD16AC instruction is used to control an SDM-CD16AC, SDM-CD16, or
SDM-CD16D 16 channel relay/control port device.
A port on an SDM-CD16xx is enabled/disabled (turned on or off) by sending a
value to it using the CD16AC instruction. A non-zero value will turn the port
on; a zero value will turn it off. The values to be sent to the CD16AC are held
in the Source array.
