IntroductionIntroduction
The QM-MD8X8 is an 8X8 QuickMedia matrix switcher designed to provide
versatile routing of up to eight inputs from QuickMedia Wall Plates and FlipTop
Boxes to any of eight QuickMedia Receivers. All signal routing is provided over
inexpensive CAT5e type cable* via Crestron's exclusive QuickMedia transport,
supporting the distribution of high-resolution RGB, video, stereo audio and
microphone signals up to a total of 450 feet end-to-end. Audio breakaway capability
allows audio signals to be routed independent of video signals.
Features and Functions
•Eight input by eight output QuickMedia matrix switcher
•QuickMedia technology carries high-resolution RGB, video, stereo
audio and microphone signals up to 450 feet using CresCAT-QM-P,

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” on page 24.
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.
CresCAT-QM Cable
CresCAT-QM
Cable
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.
The aggregate cable length of a signal path originating at a QM transmitter and
terminating at a QM receiver must not exceed 450 feet (137 meters). Video signals
12 •8X8 QuickMedia®Matrix Switcher: QM-MD8X8 Operations Guide – DOC. 6572A

Crestron QM-MD8X8 8X8 QuickMedia®Matrix Switcher
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, 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-MD8X8 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
or more than 22 ns.

Identity Code
The Net ID of the QM-MD8X8 has been factory set to 32. The Net IDs of multiple
QM-MD8X8 devices in the same system must be unique. Net IDs are changed from
a personal computer (PC) via the Crestron Toolbox™ (refer to “Establishing
Communication” on page 20).
When setting the Net ID, consider the following:
•The Net ID of each unit must match an ID code specified in the SIMPL™
Windows®program.
•Each network device must have a unique Net ID.
For more details, refer to the Crestron Toolbox help file.

Ventilation The QM-MD8X8 should be used in a well-ventilated area. The venting holes should
not be obstructed under any circumstances.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the rack environment may be
greater than the room ambient temperature. Contact with thermal insulating materials
should be avoided on all sides of the unit.
Rack Mounting The QM-MD8X8 can be mounted in a rack or stacked with other equipment. Two
“ears” are provided with the QM-MD8X8 so that the unit can be rack mounted.
These ears must be installed prior to mounting. Complete the following procedure to
attach the ears to the unit. The only tool required is a #1 Phillips screwdriver.
WARNING: To prevent bodily injury when mounting or servicing this unit in a
rack, take special precautions to ensure that the system remains stable. The following
guidelines are provided to ensure your safety:
•When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
•If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
To install the ears:
1. There are screws that secure each side of the QM-MD8X8 top cover. Using
a #1 Phillips screwdriver, remove the three screws closest to the front panel
from one side of the unit. Refer to the diagram following step 3 for a

NOTE: Cresnet data is fed through the NET connector that is internally wired to the
4-position mini-terminal block connector at each QM connector.
NOTE: In the configuration shown, the C2N-SPWS300 can operate in the “PWR
ON” position or the “PWR OFF SLAVE” position. For more information, refer to
the latest revision of the C2N-SPWS300 System Power Supply Operations Guide
(Doc. 8190).
NOTE: Power to the QM ports on the QM-MD8X8 can be applied using other
configurations. The total power usage of each port group must not exceed the port
group’s available input power. For example, if 75 watts is supplied to QM inputs 1
through 4, the total power consumption for those ports cannot exceed 75 watts.
Label the Buttons Use Crestron Engraver software to print custom labels for the QM-MD8X8’s front
panel buttons and LEDS. Crestron recommends printing on 100-pound paper. Paper
weighing less than 100 pounds will tend to crumple while sliding in, while paper
weighing more than 100 pounds may not fit.
Labels can also be created using a 3/8” label maker.
