Digital input at the MLC is triggered by a digital output from a motorized
Extron HSA 822M.
A closure to ground (switch 1) occurs when a certain condition is met on the
HSA. This closure to ground triggers the MLC.
The MLC must have the pull-up resistor to +5.0 VDC activated (switch 2 is
enabled/closed).
