Using Events, Logic, And IR
This example assumes that the microphone is already part of the system and
now the logic inputs and outputs will be manually added to the existing sys-
tem. If this is a new system, then use the logic input and logic output modes
on the edit channels control to automatically add the logic inputs and outputs
and associated events when the microphone input is defined.
Step 1: Add the logic input button.
Use the edit logic button to add a digital logic input.
As with other examples, check the wiring page to confirm that the logic input
is on the desired logic input pin.
