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.
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).
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.

QuickMedia™ Receiver Crestron QM-RX Physical Description The QM-RX is housed in a black enclosure with labels on the front and rear panels. There are three LEDs on the front of the unit for indicating the unit’s current status. All connections, except for the Cresnet and QuickMedia connections, are made on the back of the unit. There are four rubber feet on the base of the unit for stability and to prevent slippage. Refer to the following physical views.
Crestron QM-RX QuickMedia™ Receiver QM-RX Physical Dimensions Indicators The QM-RX front panel indicators are described as follows. PWR (Power) This green LED illuminates when the unit is connected to Cresnet and receives 24 VDC. NET This yellow LED illuminates when the QM-RX communicates with any device on the network. Operations Guide – DOC.
QuickMedia™ Receiver Crestron QM-RX Front Panel Ports The QM-RX front panel ports are illustrated and described as follows. 1 QM QM (Input) 8 The 8-pin RJ-45 QuickMedia transport port accepts CAT5E or CAT6 video and control signals. The QM input port conforms to the 568B wiring standard. Refer to page 2 and page 12 for additional QuickMedia wiring information. NOTE: To determine the location of pin 1 on an RJ-45 male connector, hold the connector with the cable down and the clip facing away from you.
Crestron QM-RX QuickMedia™ Receiver RGBHV is a computer signal that uses the standard High Density (HD-15) 15-pin connector. It 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.). S-VIDEO S-VIDEO One DIN type connector for S-video output.
QuickMedia™ Receiver Crestron QM-RX IR A 2-position terminal block connector is a mini-implementation of a single PRO2 IR port. The output is labeled S (signal) and G (ground). Infrared output is rated up to 1.2 MHz, at data rates up to 115k baud. Serial protocols include one-way RS-232. INPUT This 2-pin terminal block connector provides one software programmable digital input. The input is a Schmidt trigger type (nominal 2.5 V threshold) with 24 V input tolerance.
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.
QuickMedia™ Receiver Crestron QM-RX QM Network Wiring For the QuickMedia transport, use CRESCAT-QM. 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. 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.
Crestron QM-RX QuickMedia™ Receiver 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 26 for details of the SIMPL Windows procedure. The Net ID of the QM-RX has been factory set to 05.

Crestron QM-RX QuickMedia™ Receiver Configuring with SIMPL Windows NOTE: The following are acceptable file extensions for programs that include a QM-RX, developed for specific control system types: .smw projectname.smw (source file) .spz projectname.spz (compiled file for 2-Series) .usp projectname.usp (source code module for SIMPL+) .ir projectname.ir (user IR) .umc projectname.umc (user macro) .ush projectname.
QuickMedia™ Receiver Crestron QM-RX Expanded QM-RMCRX System Tree C2Net-Device Slot in Configuration Manager To incorporate a QM-RX into the system, drag the QM-RX 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-RX in Slot 5, with a default Net ID of 05 as shown in the following illustration.
Crestron QM-RX QuickMedia™ Receiver NOTE: This procedure sets the Net ID for the QM-RX in the program only. It does not automatically set the Net ID for the QM-RX 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 12.
QuickMedia™ Receiver Crestron QM-RX Detail View of Video Output Control The QM-RX provides integrated skew compensation, which corrects problems such as color separation that can occur when CAT5 cables have variations in the pair lengths. Delay skew is the difference in time (measured in nanoseconds) between the fastest and slowest pairs of a cable for a signal to travel from one end of the cable to the other.
Crestron QM-RX QuickMedia™ Receiver QM-RX Sub-Slot 01: Video Control Module Signals SIGNAL TYPE AND NAME DESCRIPTION Digital output Indicates that the connection with the transmitter is present and valid. The output will remain high for as long as the connection to the input is valid. This signal will indicate a failure if, for example, the QM cable is disconnected or damaged.

Crestron QM-RX QuickMedia™ Receiver Slot 2: C2I-RX-COM1-232 The C2I-RX-COM1-232 provides one two-way serial driver COM port for controlling serial devices over RS-232. NOTE: This port does not support RS-422 or RS-485. NOTE: C2N-NPA8 is not supported. NOTE: The [RESERVED] fields are left blank.
QuickMedia™ Receiver Crestron QM-RX To add an IR device, drag the device from the Crestron, Project, or User IR Database to the C2I-RX-IR1. The Crestron database contains hundreds of IR driver files, covering most IR devices on the market today. The IR port requires one IRP2 (infrared emitter probe) installed on each IR device. One end of the emitter is installed on or near the IR sensor window of the controlled device while the other end plugs into the port.
