QM-MD5x1

QuickMedia Wiring

The Crestron QuickMedia cable (sold under the name “Crescat-QM”) contains one
CAT5E cable and one Cresnet cable in siamese jackets. Installation of any QM
device is as simple as installing one set of QM 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 QM 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 an MD5x1 and then to the QM-RMCRX, the
total accumulated skew must not exceed 15 ns and the total cable length cannot
exceed 300 feet.

NOTE:

The length of CAT5/5E/6 cable that can be used can vary. However, the

total skew must be

≤

15 ns.

NOTE:

Longer lengths of cable may experience eventual loss of bandwidth when

viewing higher resolution sources.
