Operations & Installation Guide – DOC. 6269
The Crescat-QM cable contains one CAT5E cable and one Cresnet
siamese jacket. If you choose to use Belden MediaTwist or other CAT5E for the
AV signals, then you need to install a separate Cresnet cable for control and
power.

The pin assignment is based on the EIA/TIA 568B RJ-45 Jack standard.
To determine which pin is number 1, hold the cable so that the end of the eight
pin modular jack is facing you, with clip down and copper side up. When
looking down at the copper connections, pin 1 is on the far right.

The total accumulated skew from QM transmitter to QM receiver must not
exceed 15 ns (nanoseconds). Crestron recommends a cable with a rating of less
than or equal to 15 ns over its entire length. For example, if using a cable with a
rating of 15 ns/100 meters (100 meters = 328 feet), connecting the QM-
WMC/QM-WMIC QM transmitter with 150 feet of cable to a QM-MD7x2
switcher, and then using another 150 feet to connect the QM-RMCRX receiver,
the accumulated skew over the entire 300 feet should not exceed 15 ns.
