the MLC is set up) to control VCRs, DVD players, tape decks, a projector lift,
or screen control. Refer to the appropriate device’s user’s manual.

If outside factors such as fl uorescent light interfere with and affect the function
of the MLC, you can disable IR control of the MLC. Using a special function
SIS command (65#), you can turn off the MLC’s ability to receive IR signals
from IR signal repeaters and SCPs.
The control modules, IR signal repeater, and SCPs can be daisy chained, as
shown in the following diagram. Extron Comm-Link (CTL and CTLP) cable
is recommended for these connections. Use the following diagrams as wiring
guides.
