QuickMedia™ Matrix Switcher/Mixer
The following diagram illustrates how composite, S-video, and RGB video signals
are transmitted over the CAT5E wire.
Quick Media Video Signals on CAT5E
NOTE:
When transmitting S-video or composite video, luminance uses the green
video pathway, chrominance uses the red video pathway, and composite uses the
blue video pathway.
The pin assignments for Crescat-QM, CAT5, CAT5E, and CAT6 wiring are based
on the EIA/TIA 568B RJ-45 Jack standard.
RJ-45 QuickMedia Connector
Pin 1
To determine which pin is number 1, hold the cable so that the end of the eight-pin
modular jack is facing you, with the clip down and the copper side up. When looking
down at the copper connections, pin 1 is on the far right. The following table lists the
pin assignments on the RJ-45 connector.
