SCP power and control connectors — These two female
5-pole 3.5 mm captive screw connectors function identically
to each other and can be used interchangeably.
Connect an MLC 104/226 or a System 5 IP to either of these
connectors. On an SCP 226, you can connect an MLC or
System 5 IP to one connector, and an IR Link, another SCP, or
a control module such as an IRCM to the other connector.
The SCP can receive power from the MLC or System 5 IP
through pins A and B of either of these connectors. Wire the
connectors as shown in
System 5 IP, and Control
c
IRCM/RCM connector (SCP 226 only) — Attach an Extron
Control Module to this female 3-pole connector. A maximum
of four IRCM or RCM addresses can be used.
The maximum distance between the MLC or System 5 IP and
the farthest SCP in the chain is 200 feet (61 m). The SCP can
receive power through these connectors from the MLC or
System 5 IP, or from a 12 VDC external power supply.

SCP 104 and SCP 226 • Installation and Operation
NOTE: The SCP must be in standalone mode for
communication via SIS commands (see the
"Remote
on page 31).
Switch 2 — Sets the addresses for the SCPs
when two are connected. Ensure that this
switch is set to opposite positions on the
two SCPs. For example:
If switch 2 is set to Off (down) on the first SCP, set
•
switch 2 on the second SCP to On (up).
If switch 2 is set to On (up) on the first SCP, set switch

2 on the second SCP to Off (down).
Switch 3 — Not used
Switch 4 — Selects the SCP 104 operating
mode. Set this switch:
Off (down) if the SCP 104 will be

control modules on the SCP must be addressed
identically to the MLC or System 5 IP control
modules. See your IRCM or RCM user guide to
