Crestron QM-RX QuickMedia™ Receiver
QuickMedia™ Receiver: QM-RX
Introduction
Features and Functions
The QM-RX is a QuickMedia™ (QM) receiver designed to provide costeffective RGB and video signal routing and control as part of a complete
MediaManager A/V presentation system. Using Crestron’s exclusive
QuickMedia transport, the QM-RX receives RGB and video signals over a
single inexpensive CAT5E or CAT6 cable from any QuickMedia Wall Plate,
FlipTop Box, QM-TX transmitter, QM Processor, or QM Distribution Center.
Mounted at the projector or plasma display location, the QM-RX breaks out
composite video, S-video, and RGBHV or component signals to feed the
respective inputs on the display device. All signal routing occurs automatically
under the command of the control system based upon the input source type
selected.
The QuickMedia transport supports the transmission of RGB signals with
resolutions up to 1600 x 1200 pixels at 60 Hz. Software-controllable frequency,
bandwidth, and skew compensation adjustments are provided to maximize
image quality with up to 22 nanoseconds (ns) of delay skew.
Functional Summary
• Programmable logic via SIMPL Windows, including SIMPL+®
• One bi-directional COM port with programmable serial drivers for
controlling devices over RS-232.
• One IR port - compatible with Crestron® ST-SPL IR Splitter, for IR-
control of up to five different devices, programmable via the hundreds
of IR device drivers available in the Crestron databases.
• One digital input port for direct connection of power sensor, pressure
sensor, door sensor, room occupancy sensor, etc.
• When used with Crestron RoomView™, provides remote power
control and management of A/V devices, including: monitoring lamp
life of projectors, device status to ensure proper equipment operations,

QuickMedia™ Receiver Crestron QM-RX
The QM-RX includes one bidirectional RS-232 port and one IR/serial port for
control of the display device. A digital input port is also included to enable
direct connection of a room occupancy sensor, power sensor, or any contact
closure device.
Wiring for the QM-RX is extremely simple requiring just one CAT5E or CAT6
cable and one Cresnet
®
control cable (available together as CresCAT-QM, sold
separately). Complete MediaManager systems can be configured easily to suit a
variety of applications using Crestron SystemBuilder™ software.
Block Diagram of the QM-RX
NOTE: The QM-RX 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
CRESCAT-QM Cable
®
cable in siamese jackets.
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.

● QuickMedia Receiver: QM-RX Operations Guide – DOC. 6333
Crestron QM-RX QuickMedia™ Receiver
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 the 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.
The QM-RX can compensate for a maximum of 22 ns (nanoseconds) of skew.
To determine the allowable maximum length of installed cable, the installer
must first perform a calculation based on the skew rating of the cable.
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. Refer to page 12 for
additional QuickMedia network wiring information.
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.

Crestron QM-RX QuickMedia™ Receiver
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.
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.
