Wall Plate Media Center Crestron QM-WMC
QuickMedia wires from the output of one device to the input of another.
Installations are flexible, affordable, and fast.
CRESCAT-QM Cable
NOTE: Do not untwist the two wires in a single pair for more than 1/3-
1/2” (0.84 – 1.27 cm) when making a connection. The twists are critical
to canceling out interference between the wires.
The QuickMedia transport mechanism (receiver) uses frequency
compensation on each twisted pair video input to maintain high
resolutions (1600 x 1200) with CRESCAT-QM cable (which contains
both Cresnet and CAT5E wiring) and most good quality CAT5E and
CAT6 cables (where skew rating is ≤ 15 ns / 100 meters). The total
accumulated length of the cable determines the actual skew. For example,
when connecting the QM-WMC to a QM-MD9x2 and then to the QM-
RMCRX, the total accumulated skew must not exceed 15 ns.
NOTE: The length of CAT5/5E/6 cable that can be used can vary.
However, the total skew must be ≤ 15 ns.
