Radiocommunications Compliance Labelling.
Operations Guide – DOC. 6260A 8X8 QuickMedia™ Switcher: QM-MD8X8 •9

8X8 QuickMedia™ Matrix Switcher Crestron QM-MD8X8
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
 Consult the dealer or an experienced radio/TV technician for help.

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
(http://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 21.
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
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.

8X8 QuickMedia™ Matrix Switcher Crestron QM-MD8X8
Identity Code
The Net ID of the QM-MD8X8 has been factory set to 06. 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. 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.
Hardware Hookup
Ventilation The QM-MD8X8 should be used in a well-ventilated area. The venting holes should
not be obstructed under any circumstances. If the QM-MD8X8 is hot to the touch,
consider using forced air ventilation and/or incrementing the spacing between units.
To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. 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.
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
detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
by the screws in step 1.
12 •8X8 QuickMedia™ Switcher: QM-MD8X8 Operations Guide – DOC. 6260A

Crestron QM-MD8X8 8X8 QuickMedia™ Matrix Switcher
3. Secure the ear to the unit with three screws from step 1, as shown in the
following diagram.
Ear Attachment for Rack Mounting
USE COVER SCREWS
4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the
opposite side.
Connecting the Device Make the necessary connections as called out in the illustration that follows this
paragraph. Refer to “Network Wiring” on page 11 before attaching the 4-position
terminal block connector. Apply power after all connections have been made.

NOTE: For optimum performance, Crestron strongly recommends using
CRESCAT-QM cable, available from Crestron. Other high-quality/low skew
CAT5e/CAT6 wiring may also be used with varying performance.
The required 24 VDC power for each group of QM inputs and QM outputs can be
supplied in a variety of ways. The following wiring diagram suggests one method of
applying 24 VDC power to the QM ports. In this configuration, the C2N-SPWS300
can supply up to 75 watts of power to each group of QM ports to ensure that
sufficient power is available for QM devices that are connected to the QM-MD8X8.
The C2N-SPWS300 can also supply the power required by the QM-MD8X8.

NOTE: The QM-MD8X8 can only be powered by the 4-position terminal block
connector labeled “NET”.
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.
Labeling 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.

8X8 QuickMedia™ Matrix Switcher Crestron QM-MD8X8
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the QM-MD8X8, it is
recommended to use SystemBuilder and Digital Media Tools software for
configuring and tuning a QuickMedia system.
SIMPL Windows is Crestron’s premier software for programming Crestron control
systems. It is organized into two separate, but equally important “Managers”.
Configuration Manager Configuration Manager is the view where programmers “build” a Crestron control
system by selecting hardware from the Device Library.
• To incorporate the QM-MD8X8 into the system, drag the QM-MD8X8
from the Cresnet Control Modules | QM Series folder of the Device Library
and drop it in the System Views.
Locating the QM-MD8X8 in the Device Library
• The system tree of the control system displays the device in the appropriate
slot with a default Net ID of 06 as shown in the following illustration.
