CM/IR/SCP (Comm-Link) port
— For remote control of the MLC 104 IP Plus Series
controller or other items, you can connect up to four Extron control modules (IRCMs,
CMs), one Extron infrared signal repeater (IRL 20), and/or up to two Extron SCP 104
control panels to this port. A maximum of seven devices can be connected to this port.
See the figures on pages
NOTE:
The SCP must have firmware 1.01 or greater and DIP switch 4 in the
On (up) position to operate with the MLC 104 IP Plus. See the
SCP 104 User’s
Manual
for more details.
The SCP 104 replicates the front panel controls of the MLC. The SCP and the IR signal
repeater can receive IR signals from a remote control and send them to the controller.
Control modules can be used (once the MLC is set up) to control VCRs, DVD players,
tape decks, a projector lift, or screen control. See the user guide for the appropriate
device for details.
NOTE:
If outside factors such as fluorescent light interfere with and affect the
function of the MLC, you can disable IR control of the MLC. Using a special
function SIS command (
, see page 107), you can turn off the ability of the
MLC to receive IR signals from IR signal repeaters and SCPs.
The control modules, IR signal repeater, and SCPs
can be daisy chained. Wire the connections as
shown in the diagrams on the following pages.
Before inserting wires in the connectors, strip the
cable and apply heat shrink as shown at right.
NOTE:
The
maximum distance between
the MLC and a connected device is
200 feet (61 m).
NOTE:
The Comm-Link port provides up to
12 VDC for powering the SCP control
panel or other devices. The automatic
current protection circuit for this port
limits the draw to 0.5 amperes.
NOTE:
SCP control panel or control modules (CM, IRCM) used with the MLC
are
affected by front panel security lockout (executive mode) status changes.

TIP:
Comm-Link (CTL
and CTLP) cable,
shown at left, is
recommended
for these
connections. For
best results and
to avoid short
circuits, use
shielded wires
or wires insulat-
ed using heat
shrink (instead
of bare wires) for
the common/
drain wires.
