These two 4-pin terminal block connectors, located on the bottom side of the
QM-FTMC, are for connection to the Cresnet network. One connector is used to
connect to the Cresnet network while the second connector can be used to connect
another Cresnet device. Cresnet power to the QM-FTMC is supplied through either
of these connectors. For more information, refer to "Network Wiring" on page 14.
QM
This eight-pin RJ-45 transport port, located on the bottom side of the QM-FTMC,
allows connection of the QuickMedia cable. It carries audio, video, and microphone
signals over CresCAT-QM cable to a QuickMedia receiver or switcher. For more
information on QuickMedia refer to page 3.
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: Always use Crescat-QM cable to make QuickMedia connections.
NOTE: Crescat-QM siamese cable includes four additional wires for making
Cresnet connections.
