QuickMedia™ Transmitter:
QM-TX
Introduction
Features and Functions
The QM-TX is a Crestron® QuickMedia™ (QM) transmitter designed to provide
cost-effective RGB, video, and audio signal routing and control as part of a
complete MediaManager A/V presentation system. Using Crestron's exclusive
QuickMedia transport, the QM-TX transmits RGB, video and audio signals over
a single inexpensive CAT5E or CAT6 cable to any QuickMedia receiver.
The QM-TX accepts composite video, S-video, component video, RGBHV, and
audio signals. These signals are encoded and converted to the QuickMedia
standard and fed over a CAT5E or CAT6 cable to a QM receiver. All signal
routing occurs automatically under the command of the control system.
The QuickMedia transport supports the transmission of RGB signals with
resolutions up to 1600 x 1200 pixels at 60 Hz.

NOTE: The QM-TX 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, audios, 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 CAT5E or CAT6 UTP (unshielded
twisted pair) wire, simplifying installations.
Routing CAT5E or CAT6 UTP 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
standard CAT5E or CAT6 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
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.
CRESCAT-QM Cable

cable in siamese jackets.
The QuickMedia transport mechanism performs delay compensation on each
video input to compensate for signal skew, and frequency/bandwidth
2 • QuickMedia™ Transmitter: QM-TX Operations Guide - DOC. 6334
Crestron QM-TX QuickMedia™ Transmitter
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. In any case, the maximum aggregate cable length should
be limited to 328 feet to prevent loss of bandwidth.
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. To ensure sufficient bandwidth to support signal resolutions up to
1600 x 1200, the maximum aggregate cable length should not exceed 328 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 pin assignment is based on the EIA/TIA 568B RJ-45 Jack standard. The
following table illustrates how composite, S-video, and RGB video signals are
transmitted over the CAT5E wire. Refer to page 10 for additional QuickMedia
network wiring information.

Ports
The QM-TX ports are located on the rear panel and are illustrated and described
as follows.
Video and RGB Inputs
Five BNC type connectors are provided for video and RGB input.
Composite video is a type of video signal in which all information – the red,
green, and blue (horizontal and vertical sync) signals are mixed together.
S-video contains two separate components, luminance and chrominance (also
known as Y and C signals respectively). The luminance signal contains
brightness, intensity, and signal timing information. This signal contains all
picture information except for color. The chrominance signal contains only the
color information. You can see the complete black and white image, without the
chrominance, by only feeding the luminance signal into a monitor.
RGB is comprised of three analog video signals: red, green, blue and separate
horizontal and vertical syncs. Most computer monitors use RGB (usually called
VGA, SVGA, XVGA, etc.). RGBHV consists of red (R), green (G), blue (B),
horizontal sync (H) and vertical sync (V). Video sensing occurs on the H,
COMP, and Y connectors. RGsB format is RGB with sync on Green, and RGBS
is RGB with composite sync.
Component video contains three parts. The luminance signal (Y) contains the
black & white (brightness) information in the original RGB signal. The color
difference signal B-Y (P
) contains the blue information, minus the luminance
B
information. The color difference signal R-Y (PR) contains the red information
minus the luminance information. The color difference channels (B-Y and R-Y)
are algebraically recombined with the luminance channel to produce a full color
picture, recreating the green information through this mathematical process.
AUDIO (Input)
This 5-pin terminal block connector provides balanced/unbalanced left and
right audio signal input. Balanced audio inputs use (+) and (-) inputs and a
separate shield (ground). Unbalanced audio input uses L and R (+) inputs for
left and right signal and connects (-) to ground connector (G). Maximum line
level is 4 V

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, should 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: 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).
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure
to do so could cause equipment damage or void the Crestron warranty.
NOTE: When installing network wiring, refer to the latest revision of the
wiring diagram(s) appropriate for your specific system configuration, available
from the Crestron website.
When calculating the wire gauge for a particular Cresnet run, the length of the
run and the Cresnet power usage of each network unit to be connected must be
taken into consideration. If Cresnet units are to be daisy-chained on the run, the
Cresnet power usage of each 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 length of the run in
feet and the Cresnet power usage of the run should be used in the resistance
equation below to calculate the value on the right side of the equation.
Resistance Equation
The required wire gauge should be chosen such that the resistance value is less
than the value calculated in the resistance equation. Refer to the following table.
Wire Gauge Values
RESISTANCE WIRE GAUGE
4 16
6 18
10 20
15 22
13 Doubled CAT5
8.7 Tripled CAT5
NOTE: All 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.
Operations Guide – DOC. 6334 QuickMedia™ Transmitter: QM-TX • 9
QuickMedia™ Transmitter Crestron QM-TX
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 additional information on video connections over CAT5, refer to
the latest version of the Crestron CAT5 Wiring Reference Guide (Doc. 6137)
which is available from Crestron website (http://www.crestron.com/manuals).
NOTE: For larger networks (i.e., greater than 28 network devices), it may be
necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality
throughout the network. Also, for networks with lengthy cable runs or varying
types of network devices, it may be desirable to add a hub/repeater after only 20
network devices.
QM Network Wiring
For the QuickMedia transport, use CRESCAT-QM cable.
The aggregate cable length from transmitter to receiver cannot have a delay
skew of more than 22 ns for a given signal path originating at a QM transmitter
and terminating at a QM receiver. The aggregate cable length must not exceed
328 feet.
QM Network Topology
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.
Installer’s Toolbox
The Installer's Toolbox (a 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 Installer's Toolbox to:
• Observe system processes.
• Upload operating systems and firmware.
10 • QuickMedia™ Transmitter: QM-TX Operations Guide - DOC. 6334
Crestron QM-TX QuickMedia™ Transmitter
• 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 Installer's Toolbox allows you to perform these functions using simple
graphical views and click and drag methods.
Identity Code
Every 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. The Net ID of each unit must match an ID code specified in the SIMPL
Windows program. Refer to “Setting the Net ID in Device Settings” on page 22
for details of the SIMPL Windows procedure.
The Net ID of the QM-TX has been factory set to 1B. The Net IDs of multiple
QM-TXs in the same system must be unique. Net IDs are changed from a
personal computer (PC) via the Crestron Installer’s Toolbox.
NOTE: For detailed information on establishing communication between the
PC, control system, and the QM-TX, refer to “Communication Settings” on page
25. 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.
The Installer's 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.
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.
NOTE: You may also use SystemBuilder to perform Network ID setup. Refer
to page 19 for Network ID setup details using SystemBuilder.

First-time users will need to establish a user account.
Configuration is easy thanks to Crestron’s Windows-based programming
software. Crestron SystemBuilder software creates a complete project, with no
special programming required. SystemBuilder completes all necessary
programming for a base system including all touchpanel screens and the control
system program. The program output of SystemBuilder is a SIMPL Windows
program with much of the functionality encapsulated in macros and templates.
Once SystemBuilder creates the project, the system interfaces and program logic
can be customized in SystemBuilder or can be easily modified with Crestron
development tools, i.e., SIMPL Windows and Crestron VisionTools Pro-e (VT
Pro-e) software packages.
SystemBuilder comes with templates for all supported interfaces. If a user
wishes to create a touchpanel project using templates with a different look-andfeel, this can be accomplished by making a custom template. This custom
template can then be used by SystemBuilder to create the final project files to be
loaded into the panels. Alternatively, VT Pro-e can be used to tweak projects
created with the SystemBuilder or develop original touchpanel screen designs.

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 Viewport utility to accomplish
multiple system tasks, such as uploading the program to the control system and
performing diagnostic functions.
NOTE: The information in this section assumes that the reader has knowledge
of SIMPL Windows. If not, refer to the extensive help information provided
with the software.
QM-RMCRX System View
NOTE: The QM-RMCRX control system is used in the following descriptions.
This section describes a sample SIMPL Windows program that includes a
QM-TX.
Configuration Manager is where programmers “build” a Crestron control system
by selecting hardware from the Device Library. In Configuration manager, drag
the QM-RMCRX from the Control Systems folder of the Device Library and
drop it in the upper pane of the System Views. The QM-RMCRX with its
associated communication ports is displayed in the System Views upper pane.
The System Views lower pane displays the QM-RMCRX system tree (refer to
the following graphic). This tree can be expanded to display and configure the
communication ports.

Expanded QM-RMCRX System Tree
C2Net-Device Slot in Configuration Manager
To incorporate a QM-TX into the system, drag the QM-TX from the Cresnet
Control Modules | QM Series folder of the Device Library and drop it in System
Views. The QM-RMCRX system tree displays the QM-TX in Slot 5, with a
default Net ID of 1B as shown in the following illustration.
NOTE: The first QM-TX in a system is preset with a Net ID of 1B when its
symbol is dragged into the upper pane of System Views. Additional units are
assigned different Net ID numbers as they are added.
Setting the Net ID in SIMPL Windows
Double-click the QM-TX icon in the upper pane to open the “Device Settings”
window. This window displays QM-TX device information. The Net ID can be
changed in this window using the Net ID tab, as shown in the following figure.
22 • QuickMedia™ Transmitter: QM-TX Operations Guide - DOC. 6334
Crestron QM-TX QuickMedia™ Transmitter
“Device Settings” Window
NOTE: This procedure sets the Net ID for the QM-TX in the program only. It
does not automatically set the Net ID for the QM-TX 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 10.
QM-TX Symbol in Programming Manager
Programming Manager is where programmers “program” a Crestron control
system by assigning signals to symbols. Click the plus sign of the QM-TX to
reveal the available slot.
Open the QM-TX symbol in Detail View.
Detail View of QM-TX Symbol
The QM-TX symbol contains three digital detection lines for RGB, composite
and component video detection <RGB Detect>, <Composite Detect>, and
<Y Pb Pr Detect>.
The analog <AudioComp> input and feedback is the volume adjustment for the
program audio input, -10dB to +10dB (-100 to +100 input value). This control
originates on the QM transmitter and is sent over QM with auto-compensation to
the receiver.
Actual adjustment is performed at the receiving end (QM-AE, QM-RMCRX,
QM-MD7x2, etc.).

Example Program
An example program for the QM-TX is available from the “Example Program”
section of the Crestron website (http://www.crestron.com/exampleprograms).
Uploading and Upgrading
NOTE: Crestron recommends that you use the latest 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, projects and
firmware to the system and touchpanels 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 Installer’s Toolbox.

Crestron QM-TX QuickMedia™ Transmitter
The following sections define how one would upload a SIMPL Windows
program to the control system and upgrade the firmware of the QM-TX.
However, before attempting to upgrade or upload, 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.
The procedure in this section provides details for RS-232 communication
between the PC and the control system. If TCP/IP communication is preferred,
consult the latest version of the Crestron e-Control Reference Guide (Doc. 6052)
or the respective Operations Guide for the control system. These documents are
available from the Crestron website. Refer to the following figure for a typical
connection diagram when uploading files.
Typical Connection Diagram when Uploading
NOTE: Use a standard DB9 “Null-Modem” RS-232 cable when communicating
with a QuickMedia control processor. Use a straight through cable when
communicating with a 2-Series control processor.
Serial Connection
1. Ensure that all devices are connected to the control processor and the
control processor is connected via serial cable to the PC.
Operations Guide – DOC. 6334 QuickMedia™ Transmitter: QM-TX • 25
QuickMedia™ Transmitter Crestron QM-TX
2. Open Installer’s Toolbox and click Tools | Manage Address Book to
display the communications settings. Enter the new address name, and
then click RS-232 as the connection type.
3. The PC communication settings specified here should match the
protocol that the control processor expects. The usual settings are as
follows:
• Port = COM 1 through COM 8. Select the correct COM port on the
PC.
• Baud rate = 115200.
• Parity = None.
• Number of data bits = 8.
• Number of stop bits = 1.
• Hardware handshaking (RTS/CTS) enabled.
• Software handshaking (XON/XOFF) not enabled.
“Address Book” Window – Serial Settings
4. After setting the correct parameters, click OK to return to the
Installer’s Toolbox main window.
5. Click Tools | Network Device Tree to display the devices in the
system.
TCPIP Connection
1. Ensure that all devices are connected to the control processor. For
TCP/IP, use CAT5 straight through cables with 8-pin RJ-45 connectors
to connect the LAN port on the control processor and the LAN port on
the PC to the Ethernet hub. Alternatively, you can use a CAT5
crossover cable to connect the two LAN ports directly, without using a
hub. The following table illustrates pinouts for straight through and
crossover RJ-45 cables. Pins 4, 5, 7, and 8 are not used.

Troubleshooting Communications
Use the following checklist if communication cannot be established with the
control processor.
1. Verify that you are using the correct cables. As described previously,
an RS-232 connection to a QuickMedia control processor requires a
Operations Guide – DOC. 6334 QuickMedia™ Transmitter: QM-TX • 27
QuickMedia™ Transmitter Crestron QM-TX
null modem RS-232 cable. Serial connection to a 2-Series control
processor requires a straight through cable. Direct TCP/IP connection
requires a straight through CAT5 cable with 8-pin RJ-45 connectors.
2. With a serial connection, verify that the correct COM port on the PC
has been selected. Some computers have more than one COM port;
some may be internal (e.g., for a modem). Consult the manufacturer’s
documentation for further information about the COM ports on your
PC.
3. Remove and reapply power to the control system.
4. If communication still cannot be established, contact Crestron customer
service.

Crestron QM-TX QuickMedia™ Transmitter
Appendix - QM Auto Compensation
Each QM transmitter sends an ID number to identify itself to the QM receiver.
The ID number enables the QM receiver to recall the appropriate preset cable
compensation for the incoming signal received from a variety of sources. Each
preset recalls five parameters: three skew numbers for RGB, one for Peak, and
one for Boost. The QM receiver stores 254 presets.
At the transmitter, the ID number can be either the transmitter's Cresnet ID or an
arbitrary transmit ID number.
The console command for the transmitter’s ID is xmitid, and the default is off,
which means that the Cresnet ID is used. Normally, the command is xmitid is
followed by the ID number, or by the word “OFF”. If no parameter is supplied,
the device returns to the current state.
On the receiving end, the ID number selects the presets for that source (RGB
skew, peaking, boost, and microphone parameters).
NOTE: The QM cable compensation is disabled if auto compensation on the
receiver is disabled.
When auto compensation is enabled, the receiving device is allowed to use the
auto compensation data received from the transmitter. There is a digital join
EnableVideoAutoComp on each receiver, and a corresponding console
command QMDATARX ON/OFF.
NOTE: Because video auto compensation travels on the audio line, it does not
function when audio is split up from video as in the QM-MD4X2 or any QM
switcher with audio breakaway.
