Cabling
For each SCP to be connected to a system switcher, set the rear
panel DIP switches, then follow these steps:
1.
If it hasn’t already been done when the wall box was
installed, cut a length of Extron Comm-Link cable to go
between the switcher and the SCP.
2.
Using the diagrams below as a guide, attach a 3.5 mm,
5-pole captive screw connector to each end of the cable.
Wire both ends of the cable identically (pin A to pin A,
pin B to pin B, etc.).

Connectors are included with each SCP, but the cable must
be purchased separately. See page A-4 for cable part
numbers. The cable should not exceed 300 feet
(91.4 meters) in length.

3.
Plug one end of the cable into one of the SCP’s
communications connectors, and plug the other end into
the switcher (System 5cr Plus or System 7SC).
4.
If you are using a System 7SC switcher, cut a cable and
attach connectors to it for each additional SCP that will be
connected in a daisy chain. Up to a total of 16 SCPs in any
combination of models can be daisy chained together and
connected to the System 7SC.
5.
Plug one end of the cable into the SCP’s other communica-
tions connector, and plug the other end into a communica-
tions connector on the next SCP closer to the switcher. The
illustration below shows several SCPs connected to a
System 7SC switcher in a typical daisy chain setup.

SCP 250
A daisy chain of SCPs connected to a System 7SC
The maximum distance away from the switcher that the
last SCP (or other device) in the daisy chain can be
placed is 300 feet (91.4 meters).
Each port of the System 7SC switcher provides up to
12VDC for powering the SCP control pads or other
devices. However, the total load for both ports combined
must not exceed 1 ampere. Each SCP uses 12VDC at
0.06 ampere (60 mA).
