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

NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2”
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-TX2-CC/MC 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
Operations Guide – DOC. 6777B Transmitter Computer & Media Centers: QM-TX2-CC & QM-TX2-MC • 13
Transmitter Computer & Media Centers Crestron QM-TX2-CC & QM-TX2-MC
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-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.

Identity Code
The Net ID of the QM-TX2-CC/MC has been factory set to 90. The Net IDs of
multiple QM-TX2-CC/MC devices in the same system must be unique. Net IDs are
changed from a personal computer (PC) via Crestron Toolbox™ (refer to
“Establishing Communication” on page 21).
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.

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) to
ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the QM-TX2-CC/MC; refer to the
Crestron Toolbox help file for details. There is a single method of communication:
indirect communication.

Check Network Wiring
Use the Right Wire
Calculate Power
In order to ensure optimum performance over the full range of your installation
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 daisychained on the run, the Cresnet power usage of each network unit to be daisychained must be added together to determine the Cresnet power usage of the entire
chain. If the unit is home-run 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
Strip and Tin Wire
Add Hubs
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)
2
2
L <
40,000
Where:
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).
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.
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).
