The MD7x2 contains two QM input ports for connecting QM sources. These ports
are designated as inputs 6 and 7. Each QM port has an RJ-45 port for QM signals and
a corresponding 4-position mini-terminal block connector for Cresnet control signals.
For wiring information, refer to “QuickMedia Wiring” on page 15 and “Network

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:
Use Crescat-QM, or good quality CAT5E / CAT6 cable to make QM
connections. The cumulative skew over the entire length must be less than 15 ns.
Refer to “QuickMedia Wiring” on page 15 for cable specifications.
NOTE:
When using Crescat-QM wiring, four additional wires are included for
making Cresnet connections. Refer to “QuickMedia Wiring” on page 15 for cable
specifications.
