QuickMedia™ Receiver/Processor Crestron QM-RMCRX-BA

The QM-RMCRX-BA processes standard video (i.e., DVD, VCR, camera video), RGB video and audio signals through its proprietary QuickMedia transport port.

The QuickMedia connection port is a revolutionary signal processing system that allows for transmitting and receiving any signal type (including video, audio, computer and microphone signals) via CAT5E type cable. A QuickMedia

Wall Plate (QM-WMC), QuickMedia FlipTop box, or QuickMedia Transmitter

(QM-TX) converts these signals from analog to digital and transmits them to a

QM-RMCRX-BA receiver using a CAT5E cable. The QuickMedia receiver performs frequency compensation on each twisted pair video input to maintain correct operation.

The QM-RMCRX-BA then converts each of those signal types back to standard analog signals for connection to a display (projector or flat-panel monitor), an audio amplifier, or if using the on-board amplifier, directly to speakers.

QM-RMCRX-BA outputs include:

• RGBHV

• Composite video

• S-video

• Two balanced/unbalanced line audio outputs or an balanced/unbalanced stereo (left & right) line output

• One balanced/unbalanced line-level speech output

• One 20-watt stereo output (10 W per channel), with built-in volume, bass and treble controls

The QM-RMCRX-BA QuickMedia Receiver/Processor features onboard professional digital audio processing, with volume and tone control, 12-band graphic/parametric equalization, and up to 40 ms of delay for speech audio.

The onboard mic mixer can mix the two remote microphones with stereo program signals in any proportion, so the sound is always precisely tailored to the listening environment.

All the audio features of the QM-RMCRX-BA are easily configurable using

Crestron SystemBuilder™ software. Using the sliders, you can adjust EQ filters and presets, input/output gain, and mixing levels. Select real time mode to hear the sound as it is adjusted and then create a configuration file ready to be uploaded to the QM-RMCRX-BA.

Video signals received by the QM-RMCRX-BA are applied to the display device via the RGBHV, S-video, and composite video ports. Each video output port is switched for signal selection to match the selected input source of the

QuickMedia transmitter (sold separately). The display device can also be addressed via the COM port to activate only the input of interest. Audio path routing is accomplished via mixer schemes. Refer to the following block diagram.

QM-RMCRX-BA QuickMedia Audio/Video Block Diagram

The QM-RMCRX-BA is an Ethernet control system that runs on the powerful

2-Series processor, based on Motorola’s 32-bit ColdFire ® technology. I/O options include two bi-directional COM ports, four digital inputs, two Cresnet ports, one IR port, and one 10/100 Ethernet port.

The QM-RMCRX-BA is shipped as a master controller, but may also be used as a slave. Refer to “Master-Slave Modes” in the latest version of the Crestron

2-Series Control Systems Reference Guide (Doc. 6256), available from the

Crestron website (http://www.crestron.com/manuals).

The QM-RMCRX-BA provides an integrated Web server with SSL, allowing users to control AV devices from any computer on the LAN, WAN, or even custom web pages designed using Crestron VisionTools ® Pro-e. With Crestron e-Control 2 XPanel technology, Web pages have the same look and feel as TPS


QuickMedia™ Receiver/Processor Crestron QM-RMCRX-BA touchpanel pages, with the same outstanding runtime performance. Crestron e-Control 2 also generates standalone XPanel programs that users can launch from their Windows ® desktop or from Windows PocketPC 2002 PDA devices and Windows Tablet PCs. With built-in support for SSL, users can feel confident knowing that their Crestron e-Control 2 connection to the control system is secure and private.

The QM-RMCRX-BA supports all Crestron e-Control power applications, including Crestron RoomView™ software. Using Crestron RoomView, organizations can monitor multiple room A/V controllers on an Ethernet network, in real time, from any network PC. Crestron RoomView and the

QM-RMCRX-BA can provide remote power control and management of A/V devices, including monitoring lamp life of projectors, device status to ensure proper equipment operations, room occupancy, equipment use log, and device and room security.

NOTE: DHCP (Dynamic Host Configuration Protocol) is a network protocol that enables a DHCP server to automatically assign an IP address to an individual computer’s TCP/IP stack software. DHCP assigns a number dynamically from a defined range of numbers (i.e., a scope) configured for a given network.

NOTE: DNS stands for Domain Name Service (or System). Its primary use is to translate, or resolve, the IP number for a computer (e.g., 129.79.5.208) from an alphanumeric name.

NOTE: SSL, or Secure Socket Layer, is the most commonly used protocol for

Web security. In addition to providing security for HTTP (Web hypertext) transactions, SSL works with other TCP/IP standards such as IMAP mail and

LDAP directory access. For a security standard such as SSL to work, the browser and the Web server must both be configured to use it. SSL works by creating a temporary shared “key” that only allows the devices on either end of a transmission, to scramble and unscramble information. To anyone between the sender and the receiver, the SSL transmission is indecipherable. SSL uses certificates to verify that a device, browser or server is authentic. In addition, all data sent over an encrypted SSL connection is protected with a mechanism for detecting tampering — that is, for automatically determining whether the data has been altered in transit. Crestron’s implementation of SSL supports selfsigned certificates and certificates issued by official Internet Certifying

Authorities combined with assignable security levels and password protection.

Crestron SSL integration uses the RSA 1024 bit Key Exchange Algorithm with a host of cipher suites.

The QM-RMCRX-BA also provides two isolated relays for controlling low voltage contact closure devices such as drapes, screens and lifts.

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 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


Crestron QM-RMCRX-BA QuickMedia™ Receiver/Processor 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 ® cable in siamese jackets.

CRESCAT-QM Cable

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.

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.

Refer to Appendix B on page 65 for additional QuickMedia 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.

Display Device Selection for a QuickMedia

System

QuickMedia fully integrates the display device with the system. Consequently, careful selection of a display device is required to take full advantage of this capability. A projector should support discrete video switching commands. This enables the QuickMedia receiver/processor to seamlessly pass along the three different video types to the display and alert the display to switch inputs.

In addition, the display device should support discrete power on and off commands. This enables a system “Room On” button function that will energize the display. If the display device has a toggle on/off power command, there is a possibility of getting out of sync with the room power. Most RS-232 display drivers in the Crestron database support discrete commands. Refer to the

Crestron Database in System Builder or the Dealer/Tech Resources | Whose

Products Do We Control? Section of the Crestron website for a list of products.

Reset Buttons

Two buttons are provided on the front panel of the QM-RMCRX-BA. Refer to the following descriptions.

HW-R

Pressing this button initiates system hardware reset. (Same effect as disconnecting and reconnecting power.)



SW-R

Pressing this button in combination with the HW-R button performs a system restart without loading the program (refer to “Establishing Console Mode on an

Ethernet Slave” on page 24). Press HW-R momentarily while pressing and

holding SW-R to reboot.

Pressing SW-R alone while the system is running restarts the program.

Serial console connection may be established if SW-R button is pressed and held about five to seven seconds during power up (wait for Toolbox to display some information), or if pressed and held at the same time HW-R is momentarily pressed. The serial console mode is also established if the processor is configured as a master, but has no program loaded. In this way, the console mode is enabled out-of-the-box and the user does not have to perform any special steps to initially configure the processor.

NOTE: The COM B LED will flash when in the console mode.

To terminate the console mode, press the HW-R button or cycle the power.

NOTE: Pressing <F10> (Program Reset) in Toolbox may cause errors if both the program and the console mode are using the same COM port.

Memory

The QM-RMCRX-BA has 36 MB of built-in memory (non-volatile and volatile). The total of 36 MB is specified as follows: 4 MB flash (non-volatile),

32 MB SDRAM (volatile), and 256 KB NVRAM (battery backed up). Flash memory contains the file system inside the 2-Series control engine. Non-volatile memory contains information that is retained after the loss of electrical power.

Volatile memory is lost after a power failure.

The 4 MB flash memory consists of approximately 1.5 MB used for firmware, and approximately 2.5 MB available for SIMPL, SIMPL+, and Web pages. The files that reside in flash conform to a flat directory structure.

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

4 16

6 18

10 20

15 22

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.

QM Network Wiring

When connecting multiple QM devices, the route between a QM origination point (e.g., QM-TX) 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. The aggregate length from transmitter to receiver cannot have a delay skew of more than 22 ns.

NOTE: Refer to Appendix B on page 65 for detailed auto-compensation

information.

QM Network Topology

Mounting

The QM-RMCRX-BA can be mounted using the included four mounting brackets. Attach the included brackets using the existing cover screws located on the sides of the QM-RMCRX-BA as shown in the following diagram.



Mounting Positions of the Four Included Mounting Brackets

NOTE: The MK-QM-RMCRX mounting kit is available for mounting the

QM-RMCRX-BA to a pipe. Details can be found in the latest version of the

MK-QM-RMCRX Installation Guide (Doc. 6247).

Hardware Hookup

Refer to the following hookup diagram and, aside from attaching power last, complete the connections in any order.

NOTE: To prevent overheating, do not operate this product in an area that exceeds the environmental temperature range listed in the specifications table.

Consideration must be given if installed in a closed or multi-unit rack assembly since the operating ambient temperature of the rack environment may be greater than the room ambient. Contact with thermal insulating materials should be avoided on all sides of the unit.

NOTE: The maximum continuous current from equipment under any external load conditions shall not exceed a current limit that is suitable for the minimum wire gauge used in interconnecting cables. The ratings on the connecting unit's supply input should be considered to prevent overloading the wiring.



Front Connections

Rear Connections

NOTE: COM B is shared for device control and serial console connection.

NOTE: Use either the internal amplifier (SPEAKER) output or the AUDIO left and right line outputs, but not both. Using both induces noise.



Ground Wire Connections

Proper grounding is required. Connect the ground from the QM peripheral (in this example a QM-WMC) to earth ground. Connect the Cresnet shield lead at the QM-RMCRX-BA control processor to the ground lead. The control processor chassis must also be connected to an earth ground (building steel).

Refer to the following grounding diagram.

Grounding Diagram

Power Supply

The QM-RMCRX-BA can be powered through the NET network connector

(Cresnet), or by the external PW-2420 power pack (50W) included but not by

both methods. Use the provided external power pack to provide power to peripheral Cresnet devices (via the Cresnet connector).

If additional power is needed, Crestron recommends its CNPWS-75 (75 watts) external power supply.

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do so could cause equipment damage or void the warranty.

NOTE: Use care in wiring installations to avoid applying 24 VDC power to

Cresnet wiring from an external power pack as well as from a system device that contains its own power supply. Although this condition should not cause any damage, Crestron does not recommend it.

NOTE: In larger system configurations that require more power than supplied by Cresnet, disconnect the +24 VDC wire from the QM-RMCRX-BA Cresnet connector and provide the +24 VDC power to the peripheral devices by an alternate Crestron power source.

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.

Communication Settings

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.

Crestron Toolbox - Text Console Open

Establishing Console Mode on an Ethernet Slave

Enter serial console mode by holding down the SW-R button while booting up.

The COM B LED will flash to indicate console mode.

Please be aware that doing this causes the processor to boot up in standalone mode, rather than Ethernet slave mode. You will notice that the Ethernet master shows this device as being off-line.

To put the processor back in Ethernet Slave mode and use the serial console, type: REBOOT at the console prompt. This will reboot the processor in slave mode, and enable the serial console.

NOTE: Booting up in serial console mode will render COM B useless to the program, as it is being used for the serial console.

To terminate the serial console mode, press the HW-R button, or cycle the power.

NOTE: Pressing <F10> (or selecting Functions | 2-Series | Hard Reset) in

Toolbox for the master control system may cause errors if both the program and the console mode are using the same COM port.

For more information on slave mode operation, refer to the latest version of the

2-Series Master/Slave Modes Reference Guide (Doc. 6164).

Troubleshooting Communications

Use the following checklist if communication cannot be established with the

QM-RMCRX-BA.

1. Verify that you are using the correct cables. As described previously, an RS-232 connection requires a null modem RS-232 cable with DB9 female connectors on both ends. TCP/IP connection requires a 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. Ensure that the COM B LED is flashing.



3. Ensure that you have a serial connection to Port B, and reset the control system as follows: a. In Toolbox, click Tools | Manage Address book to display the

“Address Book” window. Choose RS-232 as the connection type. b. Set the baud rate of the PC to 115200. c. Set the baud rate of the QM-RMCRX-BA control system to

115200, as follows:

- Press and release the HW-R button on the unit’s front panel.

- Press and hold the SW-R button for approximately three to five seconds. The Toolbox console should display the following message:

Toolbox Message

QM-RMCRX-BA>

Control Console

Changing to default Comm Specs. 115200 N81 RTS/CTS

Switch to new settings….

Bypassing Program Load!!!

- Ensure that the COM B LED is flashing. d. If communication still cannot be established:

- Remove power from the control system.

- Press and hold the SW-R button on the front panel of the

QM-RMCRX-BA.

- Reapply power to the control system while still holding the

SW-R button.

- The Toolbox console should display the message shown above.

- Ensure that the COM B LED is flashing.

Set Baud Rate in the Toolbox “Address Book” window (or press F8) and choose any baud rate. This will attempt to establish a connection at the indicated baud rate. If the connection is successful, both the PC and the control system will be set to the new baud rate. The QM-RMCRX-BA will return to its original communication settings when the program reinitializes. f. Reinitialize the unit by recycling the power or pressing the HW-R button while pressing and holding the SW-R button. If the connection is established, the Toolbox console should display some text and the QM-RMCRX-BA> prompt. g. If communication still cannot be established, contact Crestron customer service.



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.

Net IDs can be changed from a personal computer (PC) using SystemBuilder ™ or Crestron Toolbox.

The Net ID of the QM-RMCRX-BA has been factory set to 02, which designates the QM-RMCRX-BA as a master control unit.

In slave mode, the QM-RMCRX-BA operates as a 2-Series Cresnet or Ethernet device. For example, the QM-RMCRX-BA can be part of a larger master control system that includes: audio and video switching, IR, relay control, and Ethernet, using touchpanels to operate the QM-RMCRX-BA slave through the master

2-Series control system. To operate the QM-RMCRX-BA as a slave, the Cresnet

ID must be set to 03 or higher.

The hardware ID can be changed using Crestron Toolbox. The software ID must

match the hardware ID and is changed using SystemBuilder (page 36).

NOTE: When in slave mode, the QM-RMCRX-BA cannot address any Cresnet device on the operating network (only the controlled devices directly connected to the local ports of the slave, such as drapes, lifts, etc.). Only the master control system can address Cresnet devices.

NOTE: When operating in the slave mode, any program loaded in the

QM-RMCRX-BA will not run.

NOTE: When operating in the slave mode, The QM-RMCRX-BA is controlled by a 2-Series master control system only.

NOTE: When operating in the slave mode, Crestron Toolbox functions

(including firmware upgrades) can be used on the slave device.

NOTE: Ensure that the QM-RMCRX-BA is connected to your computer. For detailed information on establishing communication between the PC, control system, and the QM-RMCRX-BA, refer to “Communication Settings” on page

20. If communication cannot be established, refer to the “Troubleshooting

Communications” section.

1. Once communication is established, the System Info window opens and the Functions menu becomes available.



Crestron Toolbox – Functions Menu


3. Select the new Net ID from the pull-down list. Ensure that the new hardware ID agrees with the ID assigned in SystemBuilder and is not a duplicate.

Parametric Equalization

SystemBuilder provides parametric equalization for left, right and speech.

Specific filter types are available for low/high pass, bass/treble shelf and normal

EQ. The frequency, gain and bandwidth are selectable.

Parametric EQ

Video Settings

Video Settings

SystemBuilder software is also used to adjust the video peaking, boost, and skew of a QM system. Peaking, boost and skew are all used to compensate for cable length. The first bitmap (for Steps 1 and 2) consists of lines of black text on gray and white backgrounds, and lines of blue text on gray and white backgrounds. You may also browse for your own bitmap test image.



Step 1 – If the text is blurred and the text color persists (smears) into the blank space after the text, this is "black streaking" and you need to increase the peaking value. If you see white bands persisting after the text or you see small white areas after the text, you have "white streaking" and you need to decrease the peaking value.

Black and White Streaking

Step 2 – If you see "blooming" or pixel areas that appear larger than normal, you need to decrease the boost.

Step 3 – The QM skew bitmap consists of two sets of three vertical lines of red, green and blue positioned directly over one another. The amount of skew is determined by observing which line is shifted farthest to the right. The line farthest to the right has the most skew delay. Adjust the other two lines by increasing their skew so that they all line up. In the following example, increase red and blue to match green.

Step 4 – The crosshatch test pattern is displayed. Re-check your adjustments.

Lines should appear crisp and all white. If there are color outlines, return to the skew adjustment. If they are smeared, perform peak and boost again. If they are unstable, check for induced noise.

• If you see any color outlines, return to the skew adjustment.

• If the lines appear smeared, return to the peaking and boost adjustments.

• If the lines are unstable and exhibit some crawl, check the system for induced noise.

NOTE: An image that is not horizontally or vertically centered indicates that an adjustment of the monitor or projector is needed, and is not a problem with the

Crestron QM system.

NOTE: All presets are immediately stored to the QM-RMCRX-BA, even those on other screens. There is no need to explicitly save them.

NOTE: You may also use the browse button to load third-party video test patterns (if installed).

For additional details, download SystemBuilder from the Crestron website and examine the extensive help file.

Slot 09: C2I-RX-GRAPHICEQ

Slot 10: C2I-RMC-Front Panel (not programmable)

Slot 12: C2I-RX-RY2

NOTE: The QM-RMCRX-BA does not have a Slot 11.

Slot 1: C2I-RMC-IR1

The C2I-RMC-IR1 provides one IR output port for controlling devices via IR or one-way RS-232. (Depending on the control format, additional equipment such as IR emitters, splitters, receivers, and remote control transmitters may be required). No detail is required, and no symbol is shown.

To add an IR device, drag the device from the Crestron, Project, or User IR

Database to the C2I-RMC-IR1 port. 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 IR port on the QM-RMCRX-BA rear panel. This port can handle a single IRP2 that can be attached to a single IR device.

The ST-SPL resistor/divider can be used to split the one infrared (IR) port into five ports, and allow control of up to five devices via multiple STIRP Infrared

Probes. The five ST-SPL output ports can be connected to any combination of five IR probes (STIRP) and/or Master Blaster IR Sprayers (ST-MB/STI-MB).

The ST-MB (master blaster) IR sprayer can "spray" IR signals 90 degrees. It eliminates the need for IR probes and resistors, and can be positioned to reach all devices. It is designed to handle multiple IR codes so that only one sprayer is needed for many devices.

NOTE: The C2I-RMC-IR1 port does not support simultaneous IR and RS-232 control. That is, an IR driver cannot be stacked on the port together with a oneway serial driver. The control format must be of one type. Use only one 1-way serial driver or up to five IR drivers.

In addition, the IR port does not have negative voltage and thus may not provide the full voltage range required by some RS-232 devices (although nearly all

RS-232 devices will operate properly). In these cases the DB9 serial COM ports can be used instead.



Slot 2: C2I-RMC-DI4

Slot 2 provides four digital input ports: <i1> through <i4>.

Detail View of Digital Input Port

The C2I-RMC-DI4 provides four digital inputs for connection of external sensors or other contact closure devices. The <i> outputs are a logical high until it detects the presence of a low on the corresponding input.

The built-in port supports dry contact closure to ground.

Slot 3: C2I-RMC-COM2-232 - Port A and Port B

The C2I-RMC-COM2-232 provides two COM ports (A and B) for controlling serial devices over RS-232. Each COM port has a built-in two-way serial driver.

Use the console command comconsole on or comconsole off to enable or disable port B for serial communication.

NOTE: Does not support RS-422 or RS-485.

NOTE: COM B cannot be used to control a device when a PC is controlling the

QM-RMCRX-BA through the console on this serial port.

NOTE: The [RESERVED] field is left blank.

NOTE: C2N-NPA8 is not supported.

Slot 5: Cresnet: C2Net-Device

The C2Net-Device slot enables the QM-RMCRX-BA to control up to 252

Cresnet devices. Each Cresnet device is assigned a unique identifier called a Net

ID, which is a hexadecimal value ranging from 03 to FE.

To view the list of supported devices, expand the control system in the bottom pane of System Views and double-click the C2Net-Device slot, the desired Net

ID, or right-click and select Add Item from the submenu. Then select the device you want to add. Alternatively, you can drag the device from the Cresnet

Control Modules folder onto the Net ID. Supported devices include network control modules, lighting modules and a variety of Crestron wired touchpanels.

In Program Manager, the C2Net-Device symbol contains no signals; to program a controlled Cresnet device, expand C2Net-Device in Program View. Then drag each device to Detail View.



Slot 6: C2I-RXBA-VIDEO

The C2I-RXBA-VIDEO module is built into slot 06 of the QM-RMCRX-BA.

The QM-RMCRX-BA provides one QM input, labeled QM, which receives composite video, S-video and RGB video as well as digital audio from a

QuickMedia transmitter such as the QM-WMC or QM FlipTop box.

The QM-RMCRX-BA provides the following video outputs:

• One BNC output labeled VIDEO for composite video.

•

•

One mini-DIN output labeled S-VIDEO for S-video.

One RGB output labeled RGBHV for computer video.

The C2I-RXBA-VIDEO module can route any video source to the corresponding output for transmission to the display device.

The QM-RMCRX-BA supports up to 254 skew presets, where a skew preset consists of three RGB skew values together with peaking and boost. Each skew preset applies to the cable connection between the QM-RMCRX-BA and a specific QM transmitter.

During normal program operation the system will recall a pre-configured preset corresponding to the transmitter currently connected to the QM-RMCRX-BA. If automatic video compensation is NOT enabled, the program must supply the correct preset number using the <SkewPreset#> analog and recall the preset manually.

If auto-compensation is enabled (via the <EnableVideoAutoComp> input), then <SkewPreset#> is ignored and the QM-RMCRX-BA will automatically extract the correct preset number directly from the transmitter's QM signal.

Depending on how the transmitter is configured, the QM signal will be identified by a Transmitter ID (XMIT ID) or Cresnet ID. Auto-compensation mode thus allows for an easier way to recall presets during runtime.

Slot 7: C2I-RX-MIXER

The C2I-RX-Mixer module is built into slot 07 of the QM-RMCRX-BA

QuickMedia control system and audio/video receiver. It provides one QM input labeled QM that receives four channels of digital audio as follows:

• Two channels of stereo program audio, referred to as LEFT and

RIGHT.

Two microphone channels referred to as MIC 1 and MIC 2. •

The unit provides one 9-pin balanced/unbalanced line level audio output labeled

AUDIO, with three channels labeled L, R and SPCH.

The Mixer module can mix the four input channels into any output channel. In addition, an onboard four-band equalizer (160 Hz, 500 Hz, 1.2 kHz, and 3 kHz) for MIC 1 and MIC 2 applies equalization to the mic audio before mixing.

The Mixer module provides up to five mixer presets, where a mixer preset consists of 12 mixing levels (four mixing levels each for AUDIO L, R, and

SPCH).

In addition, the Mixer module supports up to 10 microphone EQ presets for

MIC 1 and MIC 2, where a microphone EQ preset consists of eight trim values

(four trims each for MIC 1 and MIC 2).

When audio automatic compensation is enabled (auto compensation models only), the microphone EQ presets are not used. Instead, the eight microphone

EQ values stored at the QM transmitter for the selected audio source are propagated to the QM receiver.

For the QM-RMCRX-BA, auto compensation is enabled via the

<EnableAudioAutoComp> input on the C2I-RX-GENAUDIO-AUTOCOMP slot.

Slot 9: C2I-RX-GRAPHICEQ

The C2I-RX Graphic EQ module is built into slot 09 of the QM-RMCRX-BA

QuickMedia control system and audio/video receiver.

The QM-RMCRX-BA provides graphic and parametric equalization for each of the three audio output channels: Program Left, Program Right and Speech audio

(Mic Mix Out). The parametric equalizer and fixed frequencies of the graphic equalizer can only be programmed using SystemBuilder.

The QM-RMCRX-BA provides 12 filters per output, with a maximum of 10 filters available for graphic EQ. The QM-RMCRX-BA provides five modes of audio equalization (settable using SystemBuilder).

• 10 bands graphic EQ + 2 band parametric EQ. In this mode, the first 10 filters of the three channels are used to set up the fixed frequencies for graphic equalization, leaving filters #11 and #12 available for parametric EQ.

• 3 bands graphic + 9 bands parametric

• 5 bands graphic + 7 bands parametric

• 5 bands graphic + 7 bands parametric, with speech optimization

• 12 bands parametric (0 bands graphic)



NOTE: Programming the graphic equalizer through SIMPL Windows may override the SystemBuilder software settings. For example, if the 12-band parametric equalizer mode is specified in SystemBuilder and the SIMPL

Windows program selects/recalls filter #2, the system will allow the change.

Filter presets can only be recalled from SIMPL Windows and not modified.

The QM-RMCRX-BA provides 10 trim presets, where a trim preset is the set of all available (maximum of 10) <TrimBand> values for the graphic EQ filters.

The <TrimBand> inputs adjust the gains of the graphic EQ filters. The gains are adjustable within a range of -12dB to +12dB. Valid analog values range from -120 (-12dB) to +120 (+12dB). 2-Series symbols such as the Analog Scaler with I/O Limits and Analog Ramp (Bounds Limited) are capable of handling range and sign mapping.

A <TrimBand> value of 0 (0dB) means that the signal will pass unaffected.

Values above and below 0 will boost or reduce the gain in increments of .1dB.

That is, changing the analog value by 1 signifies a boost or attenuation of 0.1 decibels.

All <Save> and <Recall> inputs are mutually exclusive and level sensitive.

Thus when <SaveTrimPreset> is driven high, the ten trim band values will be saved in the indicated <TrimPreset#>. Valid values for <TrimPreset#> range from 1 to 10.

Similarly, when <RecallTrimPreset> is driven high, the values stored in

<TrimPreset#> will be recalled and immediately propagated to the outputs.



Here the <TrimBand_F> feedback signals may have different values than their corresponding inputs.

If <RecallTrimPreset> goes high and <TrimPreset#> is set to an invalid value

(out of the 1 to 10 range) all trim settings will be cleared, and all signals will pass unaffected. This is the same as recalling a trim preset in which every trim band value is set to 0.

In addition to the 10 trim presets, the QM-RMCRX-BA provides five filter presets, where a filter preset is a set of six filters. A filter consists of the center frequency, gain, bandwidth and filter type (EQ, high/low pass, treble/bass shelf) for each of the three outputs channels. These values are only settable using

SystemBuilder software.

When <RecallFilterPreset> goes high and remains high, the current filter values stored in <FilterPreset#> (as set in the SystemBuilder software) will be recalled and applied to the outputs. Valid values for <FilterPreset#> range from

1 to 6.

If <RecallFilterPreset> goes high and <FilterPreset#> is set to an invalid value (out of the 1 to 6 range) all filters will be cleared, and all signals will pass unaffected. This is the same as recalling a filter preset in which every filter is set to 0.

Converting Programs and Modules Created for

Other Systems

A useful feature of SIMPL Windows is that you can convert a program created for another type of control system, simply by changing the target to a

QM-RMCRX-BA.

To do this you first open the program, and then replace the existing control system with the QM-RMCRX-BA. That is, drag the QM-RMCRX-BA from the

Control Systems folder onto the existing control system in System Views, and click Yes when prompted to confirm the replacement.

If the program contains SIMPL+ or User modules, the conversion might generate error messages. This is because modules and programs often contain symbols with “ambiguous” signals. For example, the inputs of the Serial to

Analog symbol can be defined as either analog or serial. Although X-Generation processors support ambiguous signals, the 2-Series processor requires all signal types to be strictly defined.

If the program you want to convert contains SIMPL+ or User modules, Crestron recommends that you first compile each module before converting the larger program. In this way, the compiler can resolve any ambiguous signals in the modules and minimize errors when the larger program is converted.

NOTE: Signals on digital I/O port may not transfer to digital input port on

QM-RMCRX-BA.

Converting SIMPL+ Modules for 2-Series

1. Open the SIMPL+ module you want to convert.

2. Choose the 2-Series processor as the target by clicking the toolbar button, as shown in the following illustration.

SIMPL+ Toolbar

NOTE: Note that you can select both X and 2-Series as the targets, so that the module works for both types of control systems. However, you are limited to

SIMPL+ keywords and functions that are supported on both systems. If you do not choose a target, then the module may or may not work, depending on the constructs that are used.

3. Save and compile the module by clicking the Save and Compile toolbar button; alternatively, click Save and Compile on the Build menu (or press F12).

Converting User Modules

1. Open the User module you want to convert.

You can select other types of control systems as well, but then you are limited to symbols that are supported by all of these platforms. The module may still work


Crestron QM-RMCRX-BA QuickMedia™ Receiver/Processor on unselected control systems so long as unsupported symbols are not used.

Selecting a control system means that you are requiring the module to work there.

“Module Header Information” Window

After you convert each module in a program, you can convert the program as described previously: drag the QM-RMCRX-BA onto the existing control system in System Views and click Yes to confirm the replacement.

For further information about compile-time errors and detailed explanations about working with modules, refer to the SIMPL Windows online help file.

Advanced Console Commands

The SIMPL Windows online help file provides a full listing of console commands that are valid for 2-Series control systems. You can access the

QM-RMCRX-BA console in a variety of ways: via a serial connection (RS-232) with a PC connected to port B, over Ethernet via the LAN port, or through

Telnet, among many other methods. It is also possible to issue console commands through logic, by adding a Console symbol to the SIMPL Windows program.

The Console symbol is only visible in the Symbol Library when “Special” is selected as the Symbol Set. Click Edit | Preferences. In the Symbol Set area of the General tab, select Special as shown in the following graphic.

Console commands are provided for advanced programmers. However, most functions and commands can be selected from the various Crestron Toolbox menus.



NOTE: For more information on console commands, refer to the 2-Series

Console Command Reference Guide (Doc. 6002). The latest version can be obtained from the Crestron website.

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.



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.



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.

* = Device with self-peaking.
