Crestron QM-DA QuickMedia™ Distribution Amplifier
Setup
Network Wiring
When wiring the 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 ).
• For larger networks, use a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality.
For more details, refer to “Check Network Wiring” on page 13.
QuickMedia Wiring
The Crestron QuickMedia cable (sold under the name “CresCAT-QM”) contains one
CAT5E cable and one Cresnet cable in Siamese jackets. Installation of any QM
device is as simple as installing CresCAT-QM wires from the output of one device to
the input of another. Installations are flexible, affordable and fast. For more
information, refer to the latest revision of the Crestron MediaManager Applications
Guide (Doc. 6244), which is available for download from the Crestron website
(
www.crestron.com/manuals ).

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.
