This Cresnet® device uses QuickMedia™ technology to facilitate an
uncomplicated connection of audio, video, and computer equipment. All media
and control signals are routed via a single QuickMedia cable for simple
installation. A complete integrated room solution is created with the addition of
a QuickMedia receiver (such as the QM-RMCRX-BA) and optional keypads or
touchpanels.
NOTE: The QM-FTDC is compatible with 2-Series control systems only.

QuickMedia Transport System
Using a new, proprietary signal routing solution, signals such as composite
video, S-video, RGBHV, audio, and microphone are all transported using a
single cable solution called QuickMedia (QM).
The QM transport system port is capable of managing computer, video, and
audio signals simultaneously through one CresCAT-QM cable, simplifying
installations.
Routing CresCAT-QM cable is less expensive and much simpler than routing
multi-colored, multi-conductor coax cable. All Crestron products using the QM
transport system are capable of sending and receiving QM signals via
CresCAT-QM cable. Installation of any QM device is as simple as installing one
set of QM wires from output to input. Installations are flexible, affordable, and
fast.
The Crestron QuickMedia cable “CresCAT-QM” contains one CAT5E cable
and one Cresnet® cable in siamese jackets.
CresCAT-QM Cable
NOTE: Do not untwist the two wires in a single twisted 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 QuickMedia transport mechanism performs delay compensation on each
video input to compensate for signal skew, and frequency/bandwidth
compensation for cable length. Signal skew occurs when part of the signal is
delayed with respect to other signal components. The amount of skew largely
depends on the length and design of the wire. Because CAT5 consists of twisted
pairs that are twisted together in the cable, unequal wire lengths are created.
The maximum aggregate cable length from QM transmitter to QM receiver is
limited by the loss of bandwidth over long distances and the amount of available
skew compensation. A cable rated at 15 ns of skew per 100 meters (328 ft.)
means that a cable will have no more than a 15 ns difference between the fastest
and slowest RGB signals over 100 meters of cable.
To determine the allowable maximum length of installed cable, the installer
must first perform a calculation based on the skew rating of the cable. The use of
low-resolution signals may allow increased cable length but must be tested with
the sources to be used. To ensure sufficient bandwidth to support signal
resolutions up to 1600 x 1200, the maximum aggregate cable length should not
exceed 328 feet.
Skew compensation is primarily relevant to RGB sources; however, any/all
video or VGA 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 particular to either Crestron and/or QuickMedia
systems.
The total accumulated skew from QM transmitter to QM receiver must not
exceed 15 ns (nanoseconds). Crestron recommends a cable with a rating of less
than or equal to 15 ns over its entire length. For example, if using a cable with a
rating of 15 ns/100 meters (100 meters = 328 feet), connecting the QM-FTDC
transmitter with 150 feet of cable to a QM-MD7x2 switcher, and then using
another 150 feet to connect the QM-RMCRX-BA receiver, the accumulated
skew over the entire 300 feet should not exceed 15 ns.

Setup
Network Wiring
CAUTION: 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 as a result 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
(http://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 a 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
40,000
Where:
L <
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 drawing 20 watts should not
have a length of run more than 333 feet.

L = Length of run (or chain) in feet.
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM
P = Cresnet power usage of entire run (or chain).
2
))
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.
NOTE: 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.
NOTE: For larger networks (i.e., greater than 28 network devices), it may
become necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal
quality throughout the network. Also, for networks with lengthy cable runs, it
may be necessary to add a Hub/Repeater after only 20 devices.
QM Network Wiring
When connecting multiple QM devices, the route between a QM origination
point (e.g., QM-FTDC) and a QM endpoint (e.g., QM-RMCRX-BA) cannot
have more than two midpoints (e.g., QM-MD7x2 or other QM switchers). Refer
to the following diagram when configuring a QM network. Refer to Appendix B
on page 54 for additional QuickMedia installation information.
QM Network Topology
Crestron Toolbox
The Crestron Toolbox (replacement for Crestron Viewport, you may continue to
use Viewport if desired) is a broad-based software package that accomplishes
multiple system tasks, primarily using an RS-232 or TCP/IP connection between
a PC and one or more Crestron control systems.
You can use the Crestron Toolbox to:
• Observe system processes.
• Upload operating systems and firmware.
• Upload programs and touchpanel projects.
• Set or change device Network IDs.
• Change serial numbers.
• Run scripts to automate tasks.
• Perform system diagnostics, and much more.
The Crestron Toolbox allows you to perform these functions using simple
graphical views and click and drag methods.
Every piece of equipment and user interface within the network requires a
unique identity code (Net ID). These codes are two-digit hexadecimal numbers
from 03 to FE (Net ID 02 is reserved for master control units). The Net IDs
reside within all Cresnet devices (hardware) and must match the Net ID as
specified in the software (SIMPL Windows) that runs the system. Refer to
“Setting the Net ID in Device Settings” on page 33 for details of the SIMPL
Windows procedure.
The Net ID of the QM-FTDC has been factory set to 1A. The Net IDs of
multiple QM-FTDCs in the same system must be unique. Net IDs can be
changed from a personal computer (PC) using SystemBuilder
Toolbox.
NOTE: For detailed information on establishing communication between the
PC and control system, refer to “Communication Settings” on page 43. If
communication cannot be established, refer to the “Troubleshooting
Communications” section in the latest version of the 2-Series Control System
Reference Guide (Doc. 6256), which is available from the Crestron website
(http://www.crestron.com/manuals).
The Crestron Toolbox provides several methods to easily set or change device
Net IDs for any device on the network. The following method permits you to
change the Net ID of any device in the network through the “Network Device
Tree” window.
™
or Crestron
NOTE: This method prevents you from setting duplicate IDs.
This method permits you to manually set the Net ID for any device in the
network, can be used to set any known Net IDs that may require changing, and
may also be used for non-TSID equipment. This method will not permit you to
choose an ID already in use by another device. A warning message will appear
if you attempt to use an ID that is already in use.
Duplicate Net ID Warning Message
This method does not change the Net ID as assigned in SIMPL windows. Refer
to page 33 for the SIMPL Windows ID change procedure.
NOTE: You may also use SystemBuilder to perform Network ID setup. Refer
to page 29 for Net ID setup details using SystemBuilder.
