Wall Mount Multimedia Interface
(QM-WMC & QM-WMC-VCC only)
The QM-WMC and QM-WMC-VCC install cleanly in a standard twogang electrical box using a decorator style faceplate (not supplied).
Individual video inputs are provided for composite, S-video
RGB/component signals, each with corresponding stereo audio, to accept
connections from portable AV devices and computers. A buffered
monitor pass-through connector is also provided to feed the RGB input
signal to a local monitor.
Connectivity for LAN and other signals can easily be added by ganging
the QM-WMC or QM-WMC-VCC together with other third-party wall
plate devices. A Crestron C2N-DB series Decorator Keypad may also be
installed for a truly complete multimedia interface and control solution.
Wiring for the QM-WMC and QM-WMC-VCC is extremely simple
requiring just a single CresCAT™QM cable (sold separately).

QuickMedia® Transport
Using Crestron’s revolutionary QuickMedia (QM) transport, all input
signals are transmitted from the QM-WMC/WMC-VCC/WCC-2 to any
QuickMedia Receiver or Distribution Center over a single inexpensive
CAT5e type cable. Computer resolutions up to 1920 x 1200 pixels at 60
Hz are supported over cable runs up to 450 feet (137 meters). Audio
signals are transmitted digitally with high performance 24-bit resolution.
QuickMedia dramatically simplifies system design and installation,
affording a higher level of performance at a lower overall cost.
NOTE: For QuickMedia wiring use CresCAT-QM, CresCAT-IM or
quality CAT5e/CAT6 cable with a delay skew of ≤ 15 ns per 100 meters;
the maximum 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.
MediaManager System Integration
Whether using just one Wall Plate Media or Computer Center or several,
complete system operation can be made transparent to the end user with
all signal routing occurring smoothly under the command of the
MediaManager control system. Complete MediaManager systems are

EDID Format Management (QM-WMC-VCC and QM-WCC-2
only)
The QM-WMC-VCC and the QM-WCC-2 allow for management of the
EDID (Extended Display Identification Data) information sent to the
connected source. Using Crestron Toolbox
resolution capabilities of each device can be assessed and managed through
the QM-WMC-VCC and the QM-WCC-2, ensuring reliable operation by

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
).
• For networks with 20 or more devices, use a Cresnet Hub/Repeater
(CNXHUB) to maintain signal quality.
For more details, refer to “Check Network Wiring” which starts on page
38.
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 from the Crestron website.

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. This phenomenon is due to the
added resistance and capacitance of longer cable lengths and is not
peculiar to either Crestron and/or QuickMedia systems. To ensure
sufficient bandwidth, the maximum aggregate cable length should not
exceed 450 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 QM pin assignment is based on the EIA/TIA 568B RJ-45 Jack
standard.
NOTE: When transmitting S-video or composite 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: When using CresCAT-QM wiring, four additional wires are
included for making Cresnet connections

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.

Uploading and Upgrading
Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most
recently released features. However, before attempting to upload or
upgrade it is necessary to establish communication. Once communication
has been established, files (for example, programs or firmware) can be
transferred to the control system (and/or device). Finally, program checks
can be performed (such as changing the device ID or creating an IP table)
to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the

Check Network Wiring
Use the
Right Wire
Calculate
Power
In order to ensure optimum performance over the full range of your installat
topology, Crestron Certified Wire and only Crestron Certified Wire may be
used. Failure to do so may incur additional charges if support is required to
identify performance deficiencies because of using improper wire.
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
CAUTION: Provide sufficient power to the system. 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).
When calculating the length of wire for a particular Cresnet run, the wire
gauge and the Cresnet power usage of each network unit to be connected
must be taken into consideration. Use Crestron Certified Wire only. If
Cresnet units are to be daisy-chained on the run, the Cresnet power usage
of each network unit to be daisy-chained must be added together to
determine the Cresnet power usage of the entire chain. If the unit is homerun from a Crestron system power supply network port, the Cresnet power
usage of that unit is the Cresnet power usage of the entire run. The wire
gauge and the Cresnet power usage of the run should be used in the
following equation to calculate the cable length value on the equation’s left
side.
Cable Length Equation
L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 mm ))
or 1.6 Ohms (Cresnet HP: 12 AWG (4 mm ))
P = Cresnet power usage of entire run (or chain)

L <
Where:
40,000
R x P
Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run using 18 AWG
Crestron Certified Wire and drawing 20 watts should not have a length of
run more than 333 feet (101 meters). If Cresnet HP is used for the same
run, its length could extend to 1250 feet (381 meters).

Crestron QM-WMC/WMC-VCC/WCC-2 Media & Computer Centers
NOTE: All Crestron certified Cresnet wiring must consist of two twisted
pairs. One twisted pair is the +24V conductor and the GND conductor and
the other twisted pair is the Y conductor and the Z conductor.
Strip and Tin
Wire
Add Hubs
When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share
a pin on the network connector and tin the twisted connection. Apply solder
only to the ends of the twisted wires. Avoid tinning too far up the wires or
the end becomes brittle. Insert the tinned connection into the Cresnet
connector and tighten the retaining screw. Repeat the procedure for the
other three conductors.
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the
number of Cresnet devices on a network exceeds 20 or when the combined
total length of Cresnet cable exceeds 3000 feet (914 meters).
