Connectors are included with the IR Link, but the cable
must be purchased separately. See appendix A for cable
part numbers.
3. Plug the 5-pole connector into one of the IR Link’s
communications connectors.
4. Cut a length of cable and attach 5-pole connectors to both
ends of it for each additional MediaLink control module
that will be connected in a daisy chain. Wire both ends of
the cable identically (pin A to pin A, pin B to pin B, etc.).
Up to a total of 4 control modules in any combination of
models and one IR Link can be daisy chained together and
connected to the MLC as long as each control module has a
2-9
unique address Refer to the Control Modules User’s Manual
and the Relay Control Modules User’s Manual for details on
addresses and DIP switches.
5. Plug one end of the cable into the IR Link’s remaining
communications connector, and plug the other end into a
communications connector on the control module. The
photo below shows an IR Link and control modules (IRCMs,
ACMs, RCMs, and/or CMs) connected to an MLC in a
typical daisy chain setup.
Do not connect more than one IR Link (either in parallel
or in series) to an MLC. Also, do not connect more than
four control modules to an MLC.

6. Connect one Extron IR Emitter to the MLC’s Display/
Source Control IR connector for each control module that
is part of the system, or connect an Extron IR Broadcaster
instead.
