Extron Electronics MLC 206 AAP EC User Guide - Manual (Page 17)

2-9 MediaLink Controllers • Installation
The control modules are Architectural Adapter Plate modules that can be
connected to the MLC to control devices such as VCR, tape, or DVD players,
or provide limited control of an optional MLS 306/506 Series switcher, or
other devices. Up to four control modules (in addition to the IR Link) can be
connected to the MLC, though the connector can hold wires for only 2-3 items
at a time, so you may wish to daisy chain the control modules together.
You must also set the control modules’ rear DIP switches so each control
module has a unique address number.
Wire the MLC’s IR/RCM 3.5 mm, 4-pole direct insertion captive screw
connector as shown in the following illustrations. Refer to the Control Modules
User’s Manual or the Relay Control Modules User’s Manual for information on
setting an address for each device. An Extron Comm-Link cable (see
appendix A for part numbers) is recommended.

CAUTION Polarity is important. If the IR/RCM connector wiring specified in the
diagram is not followed, the equipment may be damaged.
Connect a maximum of one (1) IR Link. Do not connect more than one
IR Link (either in parallel or in series). Also, do not connect more than four
(4) control modules to the MLC.
The MLC contains three relays, so you may install a maximum of one
RCM-SC or one RCM-SCLT in a system with an MLC.
The control modules are not hot swappable. When you add or remove a control
module, you must cycle (disconnect, then reconnect) the MLC’s power before
the MLC can recognize the new module and the configuration change.
