Room/relay control connections
4 Relay connector — This 3.5 mm, 6 pole direct insertion captive screw
connector provides three relays. Via the included software, these relays can
be set to control items in the room (such as lights, screens, and projector lifts)
when the display/projector is being powered up or down. They can also be
associated with other buttons. See chapters three (operation) and four (serial
communication) for details.
Use the software to specify momentary or latching contact. All the relays are
normally open, and the minimum rating is 24V, 1 A. See the following
diagrams of the relays and connector wiring, and refer to the screen,
projector lift, or AC controller manufacturer’s wiring guide
.

Accessory control connections
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. Refer to the Relay
Control Modules User’s Manual.
5 IR/RCM connector — Connect an optional IR Link signal repeater and/or
optional control modules (such as an Extron IRCM-VCR, IRCM-DVD,
IRCM-DVD+, IRCM-Tape, or an ACM,
or RCM control module) here. The
IR Link receives infrared signals from the MLA Remote and sends them
directly to the MLC, allowing the MLA Remote to be used out of the line of
sight of and/or at a greater distance from the MLC than would be possible if
the IR Link were not used.
