Sense
The Sense Port allows a contact closure to trigger IR or RS-232 sequences
programmed in VIA!TOOLS. For example, use a motion sensor to activate
a contact closure and cause automated actions such as system power on,
drapes closed, and lights dimmed.
Connect SENSE and GROUND to a contact closure device as shown in
Figure 3.6
