3. Longer lengths of CAT5/5E/6 cable can be used. However, the cumulative skew must be ≤ 15 ns for
the entire length of cable used between all QM devices. Longer lengths of cable may experience
eventual loss of bandwidth when viewing higher resolution sources. For more information, refer to
“QuickMedia Wiring” on page 16.

Physical Description
The MD5x1 is housed in a black enclosure with labeling on the front and rear panels.
Fifteen buttons with accompanying light emitting diodes (LEDs) on the front panel
are used for local control of source and destination signal switching and volume
adjustment. 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 audio, video, 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 MD5x1’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.
