Using Crestron's exclusive QuickMedia transport, the QM-TX transmits RGB, video and audio signals over a single inexpensive CAT5E or CAT6 cable to any QuickMedia receiver. The QM-TX accepts composite video, S-video, component video, RGBHV, and audio signals. These signals are encoded and converted to the QuickMedia standard and fed over a CAT5E or CAT6 cable to a QM receiver. All signal routing occurs automatically under the command of the control system. The QuickMedia transport supports the transmission of RGB signals with resolutions up to 1600 x 1200 pixels at 60 Hz. Functional Summary · · · · · · · Programmable logic via Crestron SystemBuilderTM, SIMPL Windows, and SIMPL+®. One set of video inputs consisting of five BNC connectors. Balanced/unbalanced stereo audio input. Supports RGBHV, component, composite and S-video formats. Two Cresnet® ports for loop-through connection and power supply. Auto-detection of video signals QuickMedia port for simplified A/V wiring and connection to QuickMedia receivers. Complete MediaManager systems can be configured easily to suit a variety of applications using Crestron SystemBuilderTM and SIMPL windows software. Operations Guide ­ DOC. 6334 QuickMediaTM Transmitter: QM-TX · 1 QuickMediaTM Transmitter Block Diagram of the QM-TX Crestron QM-TX NOTE: The QM-TX is compatible with 2-Series control systems only. QuickMedia Transport System Using a new, proprietary signal routing solution, signals such as composite video, S-video, RGBHV, audios, and microphone, are all transported using a single cable solution called QuickMedia (QM). The QM transport system port is capable of managing computer, video, and audio signals simultaneously through one CAT5E or CAT6 UTP (unshielded twisted pair) wire, simplifying installations. Routing CAT5E or CAT6 UTP cable is less expensive and much simpler than routing multi-colored, multi-conductor coax cable. All Crestron products using the QM transport system are capable of sending and receiving QM signals via standard CAT5E or CAT6 cable. Installation of any QM device is as simple as installing one set of QM wires from output to input. Installations are flexible, affordable, and fast. The Crestron QuickMedia cable "CRESCAT-QM" contains one CAT5E cable and one Cresnet® cable in siamese jackets. 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. CRESCAT-QM Cable The QuickMedia transport mechanism performs delay compensation on each video input to compensate for signal skew, and frequency/bandwidth 2 · QuickMediaTM Transmitter: QM-TX Operations Guide - DOC. 6334 Crestron QM-TX QuickMediaTM Transmitter compensation for cable length. Signal skew occurs when part of the signal is delayed with respect to other signal components. The amount of skew largely depends on the length and design of the wire. Because CAT5 consists of twisted pairs that are twisted together in the cable, unequal wire lengths are created. The maximum aggregate cable length from QM transmitter to QM receiver is limited by the loss of bandwidth over long distances and the amount of available skew compensation. A cable rated at 15 ns of skew per 100 meters (328 ft.) means that a cable will have no more than a 15 ns difference between the fastest and slowest RGB signals over 100 meters of cable. To determine the allowable maximum length of installed cable, the installer must first perform a calculation based on the skew rating of the cable. The use of low-resolution signals may allow increased cable length but must be tested with the sources to be used. In any case, the maximum aggregate cable length should be limited to 328 feet to prevent loss of bandwidth. Skew compensation is primarily relevant to RGB sources; however, any/all video or VGA 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 particular to either Crestron and/or QuickMedia systems. To ensure sufficient bandwidth to support signal resolutions up to 1600 x 1200, the maximum aggregate cable length should not exceed 328 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 pin assignment is based on the EIA/TIA 568B RJ-45 Jack standard. The following table illustrates how composite, S-video, and RGB video signals are transmitted over the CAT5E wire.
