Media & Computer Centers Crestron QM-WMC/WMC-VCC/WCC-2 aggregate cable length and delay skew between any QM transmitter (origination point) and QM receiver (endpoint) is 450 feet (137 meters) and 22 ns; a maximum of two QM midpoint devices may be inserted in a given QM signal path; exceptions apply, refer to each respective product manual for details. 10. The eight-pin RJ-45 QuickMedia transport port accepts CAT5E/CAT6 carrying audio, video and microphone signals.
Crestron QM-WMC/WMC-VCC/WCC-2 Media & Computer Centers Setup Network Wiring When wiring the Cresnet® network, consider the following: • Use Crestron Certified Wire. • Use Crestron power supplies for Crestron equipment. • Provide sufficient power to the system. CAUTION: Insufficient power can lead to unpredictable results or damage to the equipment. Please use the Crestron Power Calculator to help calculate how much power is needed for the system (www.crestron.com/calculators).
Media & Computer Centers Crestron QM-WMC/WMC-VCC/WCC-2 CresCAT-QM Cable CresCAT-QM Cable NOTE: Do not untwist the two wires in a single pair for more than 1/31/2” (8 - 13 mm) 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-WMC/WMC-VCC/WCC-2 and terminating at a QM receiver must not exceed 450 feet (137 meters). Video signals may experience a loss of quality over very long lengths of cable.
Crestron QM-WMC/WMC-VCC/WCC-2 Media & Computer Centers 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 diagram when configuring a QM network. NOTE: The aggregate length from transmitter to receiver cannot have a delay skew of more than 22 ns per 100 meters.
Media & Computer Centers Crestron QM-WMC/WMC-VCC/WCC-2 Installation NOTE: If the QM-WMIC is to be used, refer to the installation instructions in the latest revision of the QM-WMIC Operations and Installation Guide (Doc. 6245) which is available from the Crestron website. The QM-WMC/WMC-VCC/WCC-2 should be used in a well-ventilated area. The venting holes should not be obstructed under any circumstances.
