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 aggregate cable length of a signal path originating at a QM transmitter and 
terminating at the TPS-12G/15G/17G-QM must not exceed 450 feet (137 meters). 
Video signals may experience a loss of quality over very long lengths of cable. This 
phenomenon is due to the added resistance and capacitance of longer cable lengths 
and is not peculiar to either Crestron and/or QuickMedia systems. To ensure 
sufficient bandwidth, the maximum aggregate cable length should not exceed 450 
feet. The use of lower-resolution signals may allow increased cable length but must 
be tested by the installer with the sources to be used. The QM pin assignment is 
based on the EIA/TIA 568B RJ-45 Jack standard. 
NOTE:  QM IN 2 does not have delay skew compensation (as does QM IN 1), so 
the maximum cable length varies based upon resolution and should not exceed 450 
feet (137 meters) for standard definition video. Refer to the QM Input #2 Maximum 
Cable Length table on that follows.

*  With CresCAT-QM cable, available from Crestron. Using other may adversely affect performance and 
is not recommended. 
NOTE:  When transmitting S-video, luminance uses the green video pathway and 
chrominance uses the red video pathway. When transmitting composite video, the 
signal is carried on the blue video pathway. 
NOTE:  When using CresCAT-QM wiring, four additional wires are included for 
making Cresnet connections. 
When connecting multiple QM devices, the route between a QM origination point 
(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints 
(e.g. QM-MD7x2 or other QM switchers). Refer to the following illustration when 
configuring a QM network. 
NOTE:  The aggregate length from transmitter to receiver cannot have a delay skew 
of more than 22 ns.
