The MLC’s pull-up resistor to 3.3 VDC must be
activated (the MLC’s switch 2 closed). Refer to the
MLC 226 product manual.
The flex I/O port on an Extron IP Link ™ Ethernet
Control Interface can be used in place of the MLC 226
and its digital input port.
Bezels
The HSA 822MS ships with RJ-45/RJ-11 connector bezel plug-
ins in a variety of colors and a black, blank
bezel.
To change to a different color RJ-45 connector
bezel or if an RJ-45 connector is not needed or
desired, replace the connector bezel plug-in on
the AAP/RJ-45 panel with a bezel of a different
color or a blank plug-in. See Replacing the Bezels
in chapter 3.
If no RJ-45 connector is desired, snap
the interior RJ-45 cable onto the rear of
the blank bezel plug-in (shown at
right) to hold it conveniently out of the
way. Retain the removed connector
bezel plug-in for any possible later
use.
