FlipTop Data Center Crestron QM-FTDC
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.
QM-FTDC Block Diagram
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.
2 • FlipTop Data Center: QM-FTDC Operations & Installation Guide - DOC. 6312A
Crestron QM-FTDC FlipTop Data Center
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).

))
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
Operations & Installation Guide – DOC. 6312A FlipTop Data Center: QM-FTDC • 13
FlipTop Data Center Crestron QM-FTDC
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.

Identity Code
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

Configuring with SystemBuilder
The easiest method of
rogramming, but does not
offer as much flexibility as
SIMPL Windows.
Crestron SystemBuilder offers automatic programming for such residential and
commercial applications as audio distribution, home theater, video conferencing, and
lighting. The interface of this tool guides you through a few basic steps for
designating rooms and specifying the control system, touchpanels, devices, and
functionality. Crestron System Builder then programs the system, including all
touchpanel projects and control system logic.
Crestron SystemBuilder is fully integrated with Crestron's suite of software
development tools, including SIMPL Windows, VT Pro-e, Crestron Database,
User IR Database, and User Modules Directory. Crestron System Builder
accesses these tools behind the scenes, enabling you to easily create robust
systems.
NOTE: Modifications to the program that are made outside of SystemBuilder
(for example, in VT Pro-e or SIMPL Windows) are not preserved when you
reenter SystemBuilder.
SystemBuilder
After entering the appropriate information in each step, SystemBuilder creates
the control system logic and touchpanel pages, ready to upload to the controller.
NOTE: Crestron SystemBuilder version 2.0 or higher is required.

SIMPL Windows is the Crestron graphical, Windows®-based development tool
for programming control systems. The SIMPL Windows interface provides two
workspaces: the Configuration Manager, for configuring the control system,
touchpanels, and controlled network devices; and Program Manager, for
designing the logic and functionality of the control system.
In addition, you can use the powerful Crestron Toolbox utility to accomplish
multiple system tasks, such as uploading the program to the control system and
performing diagnostic functions. Together with the Crestron Database, these
tools provide you with the essential components you need to program the
QM-RMCRX-BA and QM-FTDC. Crestron software is available from the
Crestron website, registration is required for downloading.

NOTE: This procedure sets the Net ID for the QM-FTDC in the program only.
It does not automatically set the Net ID for the QM-FTDC itself. SIMPL
Windows automatically changes Net ID values of a device added to a program if
a duplicate device or a device with the same Net ID already exists in the
program. Always ensure that the hardware and software settings of the Net ID
match. For Net ID hardware setting details, refer to “Identity Code” on page 15.
Symbols in Programming Manager
Three symbols make up the QM-FTDC: Basic Controls, Microphone Controls,
and Buttons. These symbols may be opened in Detail View. Following each
symbol, a table lists the symbol input and output signals, respectively, and their
functional description.
Basic Controls
The Basic Controls module is built into slot 01 of the QM-FTDC.
• The QM-FTDC provides one RGB video input labeled COMPUTER,
which accepts one computer or component video source.
• The QM-FTDC provides one stereo line-level input labeled
COMPUTER AUDIO.
• In addition to the stereo audio, the QM-FTDC provides two
microphone/line-level inputs.
• The QM-FTDC provides one QM output that transmits the RGB or
component video together with the program audio and one or both
microphones via CresCAT-QM.

Microphone Controls
The Microphone Controls module is built into slot 02 of the QM-FTDC. The
unit provides two microphone/line level inputs labeled MIC 1/LINE 1 and MIC
2/LINE 2, with muting, phantom power, noise gating, and level monitoring. In
addition, auto-compensation models provide four bands of equalization (160Hz,
500Hz, 1.2kHz, and 3kHz).
The microphone audio is routed to the MIC 1 and MIC 2 channels of the QM
output together with video and stereo program audio.
QM-FTDC Symbol – Detail View of Microphone Controls
Operations & Installation Guide – DOC. 6312A FlipTop Data Center: QM-FTDC • 35
FlipTop Data Center Crestron QM-FTDC
The parameters that are associated with QM inputs are stored in the transmitter.
Input compensation and Mic EQ are examples of this. This information is then
transmitted along with the digital audio. The DSP that does the compensation
and EQ are in the receiver, but the settings now travel with the audio signal.
When you have switchers in-between the transmitter and receiver, the program
does not have to keep track of the routes and recall the preset in the receiver for
these functions. Now the receiver automatically gets this information when the
route is made, with no programming required. In addition we send the Cresnet
ID (or a user defined number for systems with multiple Cresnets), which will be
used by the receiver to automatically recall the video peaking/gain/skew
parameters.

Sets the threshold for gating. The noise gate is enabled
for as long as the <GatingEnable> input is high.
Valid gating values range from 0% to 100%.
Once the microphone audio rises above <GatingLevel>
the gate opens, allowing the signal to pass through.
If the <MicNominal> feedback pulses while the
<MicGate> feedback remains low, this indicates a
threshold that is set too high.
Indicates the gating level for the corresponding MIC/LINE
input.
Adjusts the gain of the MIC 1/LINE 1 or MIC 2/LINE 2
input.
Valid values range from 0% to 100%. This maps into the
following range:
Mic level input: -60dBV to -20dBV
Line level input: -28dBV to +12dBV
Indicates the gain being applied to the corresponding
MIC/LINE input.
Sets the time, in milliseconds, that it takes for the noise
gate to fully open after the signal exceeds the
<GatingLevel>. This prevents short spikes in the input
signal level, such as coughing, from opening the gate.
The attack time applies to both microphones.
Valid analog values range from 0d (0ms) to 100d
(100ms), with 10d to 40d being the most usable range.
Out of range values are ignored.
Indicates the attack time.
Sets the time, in milliseconds, over which the noise gate
will close. This prevents the sound from stopping too
abruptly—for example, during brief pauses in speech.
The decay time applies to both microphones.
Valid analog values range from 0d (0ms) to 5000d
(5000ms, or 5s), with 1000d to 3000d (1000s to 3000s, or
1s to 3s) being the most usable range.
Out of range values are ignored.
Indicates the decay time.
Sets the four MIC 1 EQ trims (at 160Hz, 500Hz, 1.2kHz,
and 3kHz).
Valid analog values range from -120d (-12dB) to +120d
(+12dB), adjustable in increments of 0.1dB (1d = 0.1dB).
A trim of 0d (0dB) means that the signal will pass

(www.crestron.com/exampleprograms). Search for QM-FTDC.ZIP.
Adjusting the QM-FTDC Microphone Inputs
Once a QM-FTDC is installed and configured, settings for gain, gating level,
attack time, and decay time should be set using the SystemBuilder finish tab.
NOTE: Crestron recommends that you use the latest software to take advantage
of the most recently released features. The latest software is available from the
Crestron website.
Definitions
The QM-FTDC allows for adjustments to be made to microphone input signals.
The following are definitions of terms that are commonly used when making
adjustments.
Attack Time
The time it takes (in milliseconds) from when an input signal rises above the
gating level until the microphone output signal is enabled.
Clipping
A condition in which a signal level exceeds the maximum level (the clipping
level) a circuit can handle. This is usually caused by improper gating parameters
and gain settings.
Decay Time
The time (in milliseconds) from when an input signal falls below the gating
level until the microphone output signal is muted.
40 • FlipTop Data Center: QM-FTDC Operations & Installation Guide - DOC. 6312A
Crestron QM-FTDC FlipTop Data Center
Gain
An adjustable amplification to accommodate varying input signal levels.
Gating
Gating is a function that mutes a microphone signal when the input sound level
is below a user-set threshold (gating level).
The following diagram demonstrates clipping, attack time, decay time, and
gating level.

Setting Microphone Gain
The QM-FTDC provides variable gain on the microphone inputs. The following
procedure is used to set the optimal gain for a microphone input.
Use the Realtime Mode in SystemBuilder to control phantom power, gain and
gate settings, and to monitor the gate, normal, and clip level indicators. For
information on using SystemBuilder software, refer to the extensive help
information provided with the software.
NOTE: The input gain is independent of the system’s output volume level.
1. To adjust the input gain, set the gain and noise gate to their lowest
settings. Disable the “Mute” function by removing the check from the
Mute checkbox.
2. Connect a microphone and enable phantom power if required.
3. Increase the gain while providing a “normal” sound level input to the
microphone. When the “Norm” indicator shows fairly consistent
activity, you’ve reached a good signal level for the QM-FTDC.
NOTE: The "clip" indicator shows that the signal is clipping. Let your ears be
the judge, but when the clip indicator is active, you are approaching or have
reached distortion in your QM-FTDC signal. Occasional clip indications on loud
input are expected, but constant clip indicator activity is a sign that the gain may
be set too high.
4. Set the system output volume to a desirable listening level and verify
the gain settings by listening to the system output. Some minor gain
adjustment may be required for the “best sound” in any specific
configuration.
Setting the Gating Level
The QM-FTDC provides an input level gating function that will mute a
microphone signal when the input sound level is below a user-set threshold. This
function can be enabled or disabled via software commands.
Use the Realtime Mode in SystemBuilder to control phantom power, gain and
gate settings, and to monitor the gate, normal, and clip level indicators. For
information on using SystemBuilder software, refer to the extensive help
information provided with the software.
The following procedure sets the optimal “gate level” for the microphone inputs:
1. Follow the “Setting Microphone Gain” procedure on page 42 to set the
gain for each microphone input.
2. Set the noise gate level, attack and decay times to minimum. Disable
the “Mute” function by removing the check from the Mute checkbox.
3. While providing a level to the microphone that is equivalent to the
background noise that should be gated out, increase the noise gate level
until the Gated indicator turns off. When the input sound levels are at
or below the established noise gate level, the microphone output signal
will be gated off.
4. Set the “attack time” to the minimum level and the “decay time” to the
maximum level. These settings provide the shortest time to enable the
microphone output when an input is above the gating level, and the
longest time before disabling the microphone after such an input.
42 • FlipTop Data Center: QM-FTDC Operations & Installation Guide - DOC. 6312A
Crestron QM-FTDC FlipTop Data Center
NOTE: The “attack” and “decay times” are applied to both microphone inputs.
5. Set the system output volume to a desirable listening level. While
providing realistic voice input and background noise levels, adjust the
gating level and attack/decay times to eliminate undesired input while
providing the best content quality.
Uploading and Upgrading
NOTE: Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most recently
released features. Please check the Crestron website
(http://www.crestron.com/updates) for the latest versions of software and
firmware. New users are required to register to obtain access to this site.
Assuming a PC is properly connected to the entire system, Crestron
programming software allows the programmer to upload programs and projects
to the system and touchpanel and firmware to the wall plates after their
development. However, there are times when the files for the program and
projects are compiled and not uploaded. Instead, compiled files may be
distributed from programmers to installers, from Crestron to dealers, etc. Even
firmware upgrades are available from the Crestron website as new features are
developed after product releases. In those instances, one has the option to upload
via the programming software or to upload and upgrade via the Crestron
Toolbox.
The following sections define how one would upload a SIMPL Windows
program to the control system, or upgrade the firmware of the QM-FTDC.
However, before attempting to upload or upgrade, it is necessary to establish
communications.
Communication Settings
NOTE: For laptops and other PCs without a built-in RS-232 port, Crestron
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices
with good results:
Belkin (large model) F5U103
I/O Gear GUC232A (discontinued)
Keyspan USA-19QW (discontinued)
Other models, even from the same manufacturer, may not yield the same results.
NOTE: Even with these recommended models, results may vary on the
computer being used.
Establishing communications is an essential step when setting up the control
system. Once communications are established with the control system, you can
upload programming, update firmware, and use all the diagnostic tools available
in Crestron Toolbox.
Communications can be established using a serial (RS-323) connection, or by
using a TCP/IP connection. For additional connection details, refer to
“Establishing Communications with the Control System” in the latest version of
the 2-Series Control Systems Reference Guide, Doc. 6256.

Appendix B: QuickMedia Installation and
Compensation
Installation Notes
You must pass audio through from transmitters to receivers even if you are not
using the audio signal. The information required for auto-compensation is
transmitted along with the audio. In addition, the QM Link signal indicates that
the QM cable is connected and that an audio signal is present on the cable. If a
unit does not receive an audio signal, the QM Link signal will not go high, and a
valid QM Link connection cannot be detected (video can still be displayed if
auto compensation is not used).
Certain devices terminate and re-initialize the audio path within the unit;
however, they pass on the video untouched. This creates different path lengths
for the video and audio. This difference in path length creates different peak and
boost levels for audio and video. When audio-breakaway is implemented, the
audio and video paths are likely to be different.
Compensation
Inherently, twisted pair cables experience a loss of bandwidth and signal
strength over distance. When the loss is within certain limits, the reduced signal
can be restored through peak and boost compensation adjustments. The amount
of required compensation is directly dependent on the length of the cable.
Therefore, each device in a network requires a specific amount of compensation.
Manual Compensation
In a manual compensation system, the compensation parameters, along with
microphone equalization settings, are stored in the receiver in a preset file.
When the program switches to a new transmitter, the program recalls the
compensation settings associated with the new transmitter. In large systems
containing multiple transmitters and receivers, these parameters must be stored
in multiple locations, creating a complex arrangement.
Auto Compensation
In a system utilizing auto compensation, the peak and boost values are stored in
a preset file at the receiver. The transmitter stores the input compensation and
microphone EQ settings. When the program switches to a new transmitter, the
transmitter ID, input compensation, and microphone EQ settings are sent over
the audio channel of the QM cable to the receiver. The receiver is equipped
with a hunt algorithm to search for the proper peak and boost settings. Once the
receiver acquires a QM Link signal, it can receive the audio signal containing
the transmitter ID, input compensation, and microphone EQ settings. After
receiving the transmitter ID, the receiver recalls the peak and boost preset and
uses these values to properly adjust the video signal.
NOTE: If auto compensation is used in your QM system, all QM devices must
use it. If it is not used in your QM system, it must not be used for any of the QM
devices.
54 • FlipTop Data Center: QM-FTDC Operations & Installation Guide - DOC. 6312A
Crestron QM-FTDC FlipTop Data Center
Auto Compensation with a Self-Peaking Receiver
Crestron's innovative self-peaking audio circuit eliminates the need to peak the
audio signal.
Without self-peaking the same peak and boost values are applied equally to the
video and audio signals. When these signals travel the same path, this
arrangement is satisfactory. However, when video and audio travel to a receiver
from different paths, unequal cable lengths are created. The self-peaking feature
eliminates the need to hunt for peak and boost values by allowing the receiver to
read the ID, input compensation and microphone EQ from the audio channel
regardless of the peaking and boost values applied. Then using the transmitter
ID, the receiver recalls the preset containing the proper peak and boost settings
for the video, and implements the correct input compensation and microphone
EQ settings.
NOTE: QM devices that do not have self-peaking include:
● QM-RMCRX
● QM-MD7x2
● QM-MD5x1
● TPMC-15-QM
● TPMC-17-QM
Switchers
The QM-MD7x2 and the QM-MD5x1 terminate and re-initialize the audio path
within the unit, however, they pass on the video untouched. This creates
different path lengths for the video and audio. This difference in path length
creates different peak and boost levels for audio and video. In the initial QM
receivers the video and audio circuits, peak/boost have the same settings for the
audio and video. The initial QM receivers cannot accommodate different
settings, and may experience difficulties resolving the signals.
The QM-MD8x8 and QM-MD4x2 are simply analog switches. When audiobreakaway is implemented, the audio and video paths are likely to be different.
For receivers without self-peaking audio, a probable conflict exists. For
receivers with self-peaking, auto compensation is still problematic when audiobreakaway is done since the transmitter ID is that of the audio source and the
video source is from a different device with a different transmitter ID.
The self-peaking audio circuit resolves the problem of unequal cable lengths.
Because no audio setting is required, the video can have an independent
peak/boost as set by the program.
QM-AE Audio Extractor
The QM-AE is an audio-only device. The QM cable loops through the QM-AE
from the input connector to the output connector. The QM-AE taps only the
audio signals of the QM cable. The QM-AE is a self-peaking receiver, so
peaking is not required.
Operations & Installation Guide – DOC. 6312A FlipTop Data Center: QM-FTDC • 55
FlipTop Data Center Crestron QM-FTDC
Compatibility Charts
Under certain circumstances, the audio and video may be acceptably peaked
even though the audio and video path lengths are different. Because the audio
signal is digital, and more forgiving than the video signal, it may be possible to
peak the video and have functioning audio. It is difficult to predict outcomes
because it is dependent on the difference in cable lengths, the video rates, and
acceptable video quality.
The following Auto Compensation and Audio Breakaway compatibility charts
are arranged with transmitters listed on the left and receivers listed across the
top. The QM cable exits the transmitter and the QM cable enters the receiver.
NOTE: The cable exiting the QM-AE is a loop-through and is not listed as a
transmitter.
NOTE: QM wallplates and fliptop boxes are not included because the audio and
video cable lengths are always equal.
KEY: 9 = Good operation.
1. = Operation depends on video rates and if the audio and video cable lengths are closely matched.
2. = In these cases, if the audio and video (although from different sources), switch together consistently,
the system will operate normally. If the audio and video switch inconsistently, operation then
depends on the video rates and how closely the audio and video cable lengths match.

Return and Warranty Policies
Merchandise Returns / Repair Service
1. No merchandise may be returned for credit, exchange, or service without prior
authorization from CRESTRON. To obtain warranty service for CRESTRON products,
contact the factory and request an RMA (Return Merchandise Authorization) number.
Enclose a note specifying the nature of the problem, name and phone number of contact
person, RMA number, and return address.
2. Products may be returned for credit, exchange, or service with a CRESTRON Return
Merchandise Authorization (RMA) number. Authorized returns must be shipped freight
prepaid to CRESTRON, 6 Volvo Drive, Rockleigh, N.J. 07647, or its authorized
subsidiaries, with RMA number clearly marked on the outside of all cartons. Shipments
arriving freight collect or without an RMA number shall be subject to refusal.
CRESTRON reserves the right in its sole and absolute discretion to charge a 15%
restocking fee, plus shipping costs, on any products returned with an RMA.
3. Return freight charges following repair of items under warranty shall be paid by
CRESTRON, shipping by standard ground carrier. In the event repairs are found to be
non-warranty, return freight costs shall be paid by the purchaser.

accidental damage, modification, or improper installation procedures. Furthermore, this warranty
does not cover any product that has had the serial number altered, defaced, or removed.
