8. Align the tabs on the MLC’s plunger with the notches on the diffuser plate.
Gently, but firmly, press the reassembled button into place in the MLC’s or
SCP’s front panel.
9. Repeat steps 1 to 8 as needed to relabel other buttons.
Moving a button cap to a different button
For ease of use in darkened rooms and by people with visual impairment, the
MLC’s buttons produce an audible click at each button press and
each button release. Also, the cap of one button features a small
tactile bump, much like the bumps on a computer keyboard’s “F”
and “J” keys. This cap is factory installed on the input 1 button,
but you can move it to a different button.
Wiring Peripherals to the MLC
Now that the MLC has been configured and the buttons have been labeled to match
the installation, you can cable equipment to the MLC at the installation site.
1. Install the wall box, mud ring, or other mounting hardware.
2. Run cables through the wall, floor, or furniture and out through the opening
where the MLC will be installed.
3. Remove cable jackets to about 7/8" from the end, then
strip wires no more than 3/16" (5 mm) from the end.
4. Install heat shrink around bare drain wires, and install
a larger heat shrink around the area where the outer
cable jacket ends and the inner conductors are exposed.
See the diagram at right for reference.
5. Connect wires to the MLC’s connectors and to
peripheral devices (display/projector, source devices,
optional Extron switcher, control devices, IRCMs,
SCPs). See chapter 2 for wiring details for each port.
6. For IP models, connect the network cable’s RJ-45
connector to the LAN port, and wire the included
12 VDC power supply to the MLC’s Power port, referring to chapter 2 of this
manual and the diagram below as needed
