Physical Description
The MD4x2 is housed in a black enclosure with labeling on the front and rear panels.
Twelve buttons with accompanying light emitting diodes (LEDs) on the front panel
are used for local control of source and destination signal switching. The source and
destination selection buttons can be custom-labeled with Crestron Engraver software
and 100-pound paper. Two LEDs on the front panel indicate power and network
activity. All QM, Cresnet
® , and power connections are made to the back of the unit.
A pushbutton on the rear panel with an accompanying LED is used to set the
MD4x2’s network ID. Refer to the following illustrations of the front and rear panels
and the physical views.
Two mounting ears are provided for rack mounting, and four square rubber feet are
supplied for stability and to prevent slippage in tabletop placement or stacking
configurations.
