Functional Summary (continued)

• Auto Compensation automatically recalls microphone EQ settings,

The MD5x1 is a QuickMedia™ (also known as QM) signal routing device used for the mixing, switching, and routing of audio, video, microphone, and QM signals within a QM system. Audio and video input signals can be switched to the QM/linelevel output port. The presence of an MD5x1 in a system does not necessarily improve or degrade QM signal quality, nor does it increase or decrease the length of QM cable that can be used. An MD5x1 can be connected to another MD5x1 or other QM switcher (such as the QM-MD8x8, QM-MD7x2, or QM-MD4x2) to provide additional switching capabilities.

Switching

Audio and video input signals are independently switched to the output port.

Any of the five video input signals can be switched to the QM output. The five audio inputs can be switched to the QM output and mixed into the program audio or speech channels of the local audio output.

Mixing

The MD5x1 has built in mixers for the mixing of microphone and program audio signals.

Microphone Mixing

The QM input can carry up to two microphone channels from a remote QM transmitter.

The microphone signals are fed into a microphone mixer while four bands of equalization are applied to each microphone signal. The output is routed to the microphone channel of the QM output and the speech and program audio mixers of the local audio output.

Program Mixing

A mixing stage is provided at the line-level output. The microphone mix described previously, and the selected audio input is fed to this mixer. The mixer mixes the program audio and the microphone signal into two outputs, program (stereo) and speech (monaural). The microphone mix can be mixed into the stereo program and the stereo program can be mixed into the speech. After mixing, volume, equalization and tone control can be applied.

 Reorient or relocate the receiving antenna.

 Increase the separation between the equipment and receiver.

 Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

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: 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 (www.crestron.com/calculators needed for the system.

14 • QuickMedia™ Matrix Switcher/Mixer: QM-MD5x1 Operations Guide - DOC. 6300

) to help calculate how much power is

Crestron QM-MD5x1 QuickMedia™ Matrix Switcher/Mixer

CAUTION: Possible equipment damage if miswired.

NOTE: When installing network wiring, refer to the latest revision of the wiring

diagram(s) appropriate to your specific system configuration, available from the Crestron website.

NOTE: Do not power up system until all wiring is verified. Care should be taken to ensure data (Y, Z) and power (24, G) connections are not crossed.

When calculating the wire gauge for a particular Cresnet run, the length of the run and the Cresnet power usage of each Cresnet 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 network unit to be daisy-chained must be added together to determine the Cresnet power usage of the entire chain. The length of the run in feet and the Cresnet power usage of the run should be used in the following resistance equation to calculate the value on the right side of the equation.

Resistance Equation

R <

40,000

L x P

Where:

R = Resistance (refer to the following table). L = Length of run (or chain) in feet. P = Cresnet power usage of entire run (or chain).

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 table after this paragraph.

Wire Gauge Values

RESISTANCE (R) WIRE GAUGE

10 15 13

20 22

Doubled CAT5

Tripled CAT5

NOTE: All network wiring must consist of two twisted pairs. One twisted pair is the +24V conductor and the GND conductor. The other twisted pair is the Y and Z conductors.

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 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.

QuickMedia Wiring

The Crestron QuickMedia cable (sold under the name “Crescat-QM”) contains one CAT5E cable and one Cresnet cable in siamese jackets. Installation of any QM device is as simple as installing one set of QM wires from the output of one device to the input of another. Installations are flexible, affordable, and fast.

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 QM transport mechanism (receiver) uses frequency compensation on each twisted pair video input to maintain high resolutions (1600 x 1200) with CRESCAT-QM cable (which contains both Cresnet and CAT5E wiring) and most good quality CAT5E and CAT6 cables (where skew rating is ≤ 15 ns / 100 meters). The total accumulated length of the cable determines the actual skew. For example, when connecting the QM-WMC to an MD5x1 and then to the QM-RMCRX, the total accumulated skew must not exceed 15 ns and the total cable length cannot exceed 300 feet.

NOTE: The length of CAT5/5E/6 cable that can be used can vary. However, the total skew must be ≤ 15 ns.

NOTE: Longer lengths of cable may experience eventual loss of bandwidth when viewing higher resolution sources.

Identity Code

All equipment and user interfaces within the network require 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.

Refer to the note on page 54 for a definition of Viewport.

The Net ID of the MD5x1 has been factory set to 1D. The Net IDs of multiple MD5x1s in the same system must be unique. Net IDs are changed from a personal computer (PC) via the Crestron Viewport.

NOTE: For detailed information on establishing communication between the PC and control system, refer to “Communication Settings” on page 54. If communication cannot be established, refer to the “Troubleshooting Communications” section in the respective Operations Guide for the control system.

There are two different methods—Method A or Method B—for setting the Net ID:

Method A (Cresnet address-settable ID), described on the below, applies to devices in a Cresnet system with a 2-Series control system that require a single unit be the only network device connected to the control system.

Method B (Touch Settable ID or TSID), which begins on page 19, applies to all TSID-ready devices in a Cresnet system with 2-Series control system upgrade file (CUZ) version 3.029 or later. TSID functionality makes it possible for the control system to recognize a network device via its serial number, which is stored in the device’s memory. This method does not require that any devices be disconnected from the network; Net IDs may be set with the entire Cresnet system intact. This method requires the use of the Crestron Viewport version 3.35 or later.

Use the appropriate method to set the Net ID.

Method A (Cresnet address-settable ID)

1. Ensure that the device requiring a Net ID change is the only unit connected to the control system.

2. Open the Crestron Viewport.

3. From the Viewport menu, select Functions | Set Network ID. The software checks the baud rate and then opens the "Set Network ID" window.

4. In the "Set Network ID" window, select the device requiring a Net ID change from the Current Network Devices text window.

5. Select the new Net ID for the device from the Choose the new network ID for the selected device (Hex): text box.

6. Click Set ID to initiate the change. This will display the "ID command has been sent" window.

7. In the "Command Complete" window, click OK.

8. In the Current Network Devices text window, verify the new Net ID code.

9. In the "Set Network ID" window, click Close.

18 • QuickMedia™ Matrix Switcher/Mixer: QM-MD5x1 Operations Guide - DOC. 6300

Crestron QM-MD5x1 QuickMedia™ Matrix Switcher/Mixer

NOTE: The new Net ID code may also be verified by selecting Diagnostic | Report Network Devices in the Viewport (alternately, select F4).

10. Repeat this procedure for each additional network device requiring a Net ID change.

Method B (Touch Settable ID)

Before using this method, you should have a list of all current network devices and their Net IDs, to avoid assigning duplicate IDs.

Set Net ID by TSID

These procedures are for TSID-enabled network devices during the initial configuration of a Cresnet system or when such devices are being added/replaced.

1. Ensure that all network devices are connected to the control system.

2. Open the Crestron Viewport version 3.35 or later.

3. From the Viewport menu, select Functions | Assign Cresnet ID by Serial Number. The “Set Net ID by TSID” window appears. The window is first displayed with the data fields empty.

4. Click on the Search for Touch Settable Devices button. The system searches the network and lists all TSID-enabled devices found. The list is similar to the report produced by pressing F4 (Report Network Devices); the first eight digits of each line constitute the TSID number (hexadecimal form of the serial number).

“Set Net ID by TSID” Window

Operations Guide - DOC. 6300 QuickMedia™ Matrix Switcher/Mixer: QM-MD5x1 • 19

QuickMedia™ Matrix Switcher/Mixer Crestron QM-MD5x1

5. Enter either the serial number or TSID number of the device that requires a change. The list scrolls to and highlights the device listing. The listing should show the device’s default Cresnet ID (a.k.a. Net ID).

6. Enter the Cresnet ID that the device should be set to and click OK. The number you enter should appear on the list.

CAUTION: This function does not prevent you from setting duplicate IDs. Be sure to check current assignments before entering the desired Cresnet ID number.

Serial Number to TSID Conversion

This utility is useful in a case where there are multiple devices of the same type on a network, you need to locate a particular one, you know the TSID but not the serial number, and your site installation list is based on device serial numbers. In this (or the reverse) situation, do the following:

1. Open the Crestron Viewport.

2. From the Viewport menu, select Functions | Serial Number  TSID Conversion Tool. The “Serial Number TSID Conversion Tool” window is displayed.

“Serial Number to TSID Conversion Tool” Window

3. Enter the serial number or TSID number as instructed; press the appropriate button to obtain the corresponding number.

NOTE: Enter serial numbers, including spaces, exactly as they appear on the unit label. Alpha characters in serial numbers or TSID numbers may be entered in upper or lower case.

Setup is easy thanks to Crestron’s Windows-based programming software. Crestron’s 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

SystemBuilder comes with templates for all supported interfaces. If a user wishes to create a touchpanel project using templates with a different look-and-feel, 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.

Once the program created by SystemBuilder is loaded into the control system, Digital Media Tools (DMT) Software can be used to tune the system for optimal performance. DMT software can be used to test the quality of audio and video signals as well as fine-tune audio and video settings.

Earliest Version Software Requirements for the PC

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.

The following are the earliest useable software version requirements for the PC:

• (Optional) SystemBuilder version 2.0 (due in first quarter of 2005) or later with SystemBuilder Templates version 1.0.1or later. Requires SIMPL Windows.

• SIMPL Windows version 2.05.22 or later with Library Update 320 or later. Requires SIMPL+ Cross Compiler version 1.1.

• Crestron Database version 16.4.1 or later. Required by SIMPL Windows, and Crestron Engraver.

• Crestron Engraver 2.3.0.0 or later.

Programming with SIMPL Windows

NOTE: While SIMPL Windows can be used to program the MD5x1, it is recommended to use SystemBuilder and Digital Media Tools software for configuring and tuning a QuickMedia system.

NOTE: The following are acceptable file extensions for programs that include a MD5x1, developed for specific control system types: .smw: projectname.smw (SIMPL Windows source file) .spz: projectname.spz (compiled file for 2-series) .usp: projectname.usp (source code module for SIMPL+) .umc: projectname.umc (user macro for SIMPL)

SIMPL Windows is Crestron's software for programming Crestron control systems. It provides a well-designed graphical environment with a number of workspaces (i.e., windows) in which a programmer can select, configure, program, test, and monitor a Crestron control system. SIMPL Windows offers drag and drop functionality in a familiar Windows

NOTE: In the following description, the QM-RMCRX control system is used.

This section explains how to create a SIMPL Windows program that includes an MD5x1.

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.

QM-RMCRX System View

The System Views lower pane displays the QM-RMCRX system tree. This tree can be expanded to display and configure the communications ports.

Expanded QM-RMCRX System Tree

C2Net-Device Slot in Configuration Manager

To incorporate an MD5x1 into the system, drag the QM-MD5x1 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-MD5x1 in Slot 5, with a default Net ID of 1D as shown in the following illustration.

Auto Compensation is a feature that is used to recall the stored source compensation settings on a QM transmitter. If Auto Compensation is to be used, all QM transmitters, midpoints, and endpoints in a program must use QM devices with Auto Compensation. Devices with Auto Compensation capabilities are listed in the Device Library along with devices that do not have Auto Compensation.

The MD5x1 symbol already has Auto Compensation installed. There is no MD5x1 device without Auto Compensation.

QM devices with Auto Compensation can be used in a system that does not use Auto Compensation. However, the Auto Compensation feature will not be available. QM devices without Auto Compensation can be upgraded to include Auto Compensation via firmware upgrade.

When using SystemBuilder to build a system, parameters that would be managed by Auto Compensation are automatically programmed in SystemBuilder.

For more information on Audio Compensation, refer to “Slot 5: General Audio Controls” on page 47.

Setting the Net ID in Device Settings

Double-click the QM-MD5x1 icon in the upper pane to open the “Device Settings” window. This window displays the device information for the MD5x1. The Net ID can be changed in this window using the Net ID tab, as shown in the following figure.

“QM-MD5x1 Device Settings” Window

NOTE: This procedure sets the Net ID for the MD5x1 in the program only. It does not automatically set the Net ID for the MD5x1 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 18.

QM-MD5x1 Symbols in Programming Manager

Programming Manager is where programmers “program” a Crestron control system by assigning signals to symbols. The MD5x1 is broken down into five slots. Each slot contains a programming symbol for specific functions of the MD5x1.

26 • QuickMedia™ Matrix Switcher/Mixer: QM-MD5x1 Operations Guide - DOC. 6300

Crestron QM-MD5x1 QuickMedia™ Matrix Switcher/Mixer

The programming symbol in slot (Slot 1) is for programming the switching functions of the MD5x1. The second slot (Slot 2) is for programming the MD5x1’s microphone controls. Slot 3 microphone signals that are received from the QM input. Slot 4 contains the programming symbol for the audio output’s graphic EQ controls. Slot 5 is for programming the MD5x1’s general audio controls.

The following describes each of the symbols contained in the MD5x1 object in the SIMPL Windows Programming Manager.

Slot 1: Input Switching

The Input Switching module is built into Slot 1 of the MD5x1. It provides a 5-input, single-output audio/video crosspoint.

The MD5x1 provides the following local video inputs:

• Two sets of (three) BNC inputs labeled 1 and 2, which accept up to two composite, S-video or component video sources.

• Two RGB video inputs labeled RGB 3 and RGB 4, for computer sources.

The MD5x1 provides the following local audio inputs:

• Four stereo line-level unbalanced audio inputs labeled AUD 1 through AUD 4.

is for programming the mixer (EQ) settings for the

In addition to the local AV inputs, the unit provides a QM input labeled IN 5 that can receive video, stereo program audio and two channels of microphone audio (MIC 1 and MIC 2) from QM transmitters via CAT5.

The QM input is a QM audio receiver circuit that supports up to 254 "QM Link" presets for peaking and boost. The peaking and boost settings improve the transmission of the encoded audio signal over long cable lengths.

The MD5x1 provides the following audio/video outputs:

• One QM output labeled OUT.

• One stereo line-level program balanced audio output with mute relays

labeled AUDIO OUT PRG.

• One monaural line-level speech balanced audio output with mute relays labeled AUDIO OUT SP

The unit provides the following switching scheme:

• Any of the five video sources can be switched into the QM output.

• Any of the five program audio sources can be switched into the stereo

program channel of the QM output. The audio source that is switched to the QM output will also be routed to the mixing section of AUDIO OUT.

• The remote microphone pair from IN 5 can be switched and mixed into the MIC 1 channel of OUT. The same mic mix will be routed to the mixing section of AUDIO OUT.

The MD5x1 provides graphic and parametric EQ for each of the three AUDIO OUT channels. The graphic EQ portion can be programmed using either SIMPL Windows or Crestron Digital Media Tools (DMT) software. The parametric equalizer and fixed frequencies of the graphic equalizer can only be programmed using DMT Software.

The MD5x1 provides 12 filters for each output channel, with a maximum of 10 filters available for graphic EQ. The unit supports five modes of audio equalization (settable using DMT Software):

• 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. In this mode, the first three filters of the three channels are used to set up the fixed frequencies for graphic equalization, leaving filters 4 through 12 available for parametric EQ.

• 5 bands graphic + 7 bands parametric. In this mode, the first five filters of the three channels are used to set up the fixed frequencies for graphic equalization, leaving filters 6 through 12 available for parametric EQ.

• 5 bands graphic + 7 bands parametric, with speech optimization. In this mode, the first five filters of the three channels are used to set up the graphic equalizer within the frequency ranges of the human voice, leaving filters 6 through 12 available for parametric EQ.

In large networks that do not use Auto Compensation, presets for peak, boost, input compensation, and microphone equalization will need to be manually created, stored, and recalled on each receiver for each transmitter on the network.

When Auto Compensation is enabled, each transmitter automatically transmits an ID, input compensation, and microphone equalization presets for the selected input, and then embeds them in the audio data stream. When this data stream is connected to a receiver, the receiver automatically decodes the embedded parameters and then uses the ID to recall the proper preset for peak and boost to properly receive the signal.

In a network without Auto Compensation, when switching between QM transmitters, the receiver will not know which transmitter it is connected to. Therefore, it also does not know what peak and boost values to use to receive the settings embedded in the audio data stream. To overcome this problem, when Auto Compensation is enabled, the receiver will hunt for peak and boost values that will allow the receipt of the audio data stream. This hunt algorithm will not optimize the video, but will still be able find appropriate peak and boost settings to allow reading of the required parameters that are embedded in the audio data stream. The receiver will use the Net ID that is embedded in the data stream to recall the preset peak and boost values. Once the required peak and boost values are recalled, optimum audio and video settings are recalled by the receiver.

If Auto Compensation is NOT enabled, the MD5x1 supports up to 192 source gain compensation presets, which allow for normalization of audio levels between different sources. Each compensation preset applies to the cable connection between the MD5x1 and a specific QM transmitter. If Auto Compensation is enabled (via the EnableAudioAutoComp input), the audio compensation presets are not used. Instead, the audio compensation value stored at the QM transmitter for the selected audio source is propagated to the MD5x1.

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 and projects after their development to the system and network devices. 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 Viewport.

Operations Guide - DOC. 6300 QuickMedia™ Matrix Switcher/Mixer: QM-MD5x1 • 53

QuickMedia™ Matrix Switcher/Mixer Crestron QM-MD5x1

NOTE: The Crestron Viewport is available as a pull-down command from SIMPL Windows and VT Pro-e (Tools | Viewport) or as a standalone utility. The Viewport utility accomplishes multiple system tasks, primarily via an RS-232 or TCP/IP connection between the control system and a PC. It is used to observe system processes, upload new operating systems and firmware, change system and network parameters, and communicate with network device consoles and touchpanels, among many other tasks. Viewport can also function as a terminal emulator for generic file transfer. All of these functions are accessed through the commands and options in the Viewport menus. Therefore, for its effectiveness as a support and diagnostic tool, the Crestron Viewport may be preferred over development tools when uploading programs and projects.

The following sections define how one would upload a SIMPL Windows program or upgrade the firmware of the MD5x1. 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 Keyspan USA-19QW (Discontinued)

Results may vary depending on the computer being used. Other models, even from the same manufacturer, may not yield the same results.

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 Crestron 2-Series Control System Reference Guide (Doc. 6256). These documents are available from the Crestron website. Refer to the following diagram for a typical connection diagram when uploading files.

NOTE: When connecting a PC to the QM-RMCRX, use a standard DB9 female-tofemale “null modem” cable. To connect to other control systems refer to the Operations Guide included with the control system.

Adjusting Speech and Program Audio Levels

The volume levels of the Speech and Program Audio signals at the line-level outputs can be adjusted on the MD5x1’s front panel. The volume levels of the Speech and Audio Program can be adjusted individually or simultaneously for each output channel.

Before making any volume adjustments, the volume controls must be set to adjust the desired parameter. Repeatedly press the SELECT button to toggle between the four adjustment modes: None, Speech, Program Audio, or Speech + Program Audio. When neither of the LEDs are illuminated, the volume adjustment buttons will not function. When the SPEECH LED is illuminated, any changes in volume will be made to the Speech portion of the audio signal. When the PGM LED is illuminated, any changes in volume will be made to the Program Audio portion of the audio signal. When the SPEECH and PGM LEDs are illuminated, any changes in volume will be made to the Speech and Program Audio portions of the audio signal.

NOTE: Depending on the mixer setting of the MD5x1, the actual volume that is adjusted can be varied.

For example, if the program audio output contains program audio and speech components, then raising the program output volume will raise the volume of both components simultaneously.

Similarly, if the speech output contains program audio and speech components, then raising the speech output volume will raise the volume of both components simultaneously.

Appendix: Serial Protocol

All commands and responses are printable ASCII and are terminated with a <CR> (\x0D).

The serial commands listed here are grouped into front panel functions, verbose mode functions, and switching/routing functions.

Multiple serial commands cannot be strung together.

Front Panel Functions

Front Panel Lock Commands

COMMAND FUNCTION

L0\r Unlock front panel L1\r Lock front panel L?\r Get lock status

If the MD5x1 is in the local mode and the “Lock front panel” is sent, the MD5x1 will switch to the system mode and use the switching schema specified by the control system. If the MD5x1 is already in the system mode, the operating mode will not change.

When set via serial command, the front panel lock setting is not retained when power to the MD5x1 is recycled. To retain the panel lock setting, a digital signal must be used.

When the verbose mode is on and the lock state changes, or if the MD5x1 is polled for the status of the front panel lock, the MD5x1 replies with one of the responses listed in the following table.

Panel Lock Status Replies

MESSAGE DEFINITION

L1\r Front panel is locked L0\r Front panel unlocked

Verbose Mode Functions

The MD5x1 has a verbose mode, which can be turned on or off via serial commands only. The verbose mode is used to automatically report any changes made to the switching schema. The default setting for the verbose mode is off. If the verbose mode is on, whenever a parameter of the switch changes, a message is sent from the MD5x1 that indicates the new state of the parameter. If verbose mode is off, the MD5x1 will only send messages when queried.

The setting for the verbose mode is retained even after power to the MD5x1 is cycled.

Commands can be sent to the MD5x1 regardless of the status of the verbose mode.

Switching/Routing Functions

Switching/Routing Commands

COMMAND* FUNCTION*

IxO1A\r Switch input x to the QM output audio only*. IxO1V\r Switch input x to the QM output video only*. IxO1M\r Switches the remote microphone input to the

QM output. Where “x” can be equal to 0 (off) or 1 (QM5 microphone pair).

IxO1\r Switch audio and video input x, and the

microphone input on QM5 to the QM output *.

CA1V1M1\r

O1A?\r Get status of output A (audio). O1V?\r Get status of output V (video).

O1M?\r Get status of output M (microphone).

S?\r Get status of all output channels.

Switches all outputs. Where A1 is the audio input routed to the QM output, V1 is the video input routed to the QM output, and M1 is the remote microphone input (QM5) routed to the QM output. Each audio and video input value is 2 digits, and thus can range from 00 (for no source) to 05, corresponding to inputs 1 through 5. Acceptable microphone switching values are 00 (for no microphone) or 01 (for QM5 microphone. The "XX" (or "xx") specifier should be used to denote a "don't care" condition, in which case the respective output should retain its state. Refer to the example on page 66.

* Where “x” should equal 0 (for no source) through 5, corresponding to inputs 1

through 5;. Thus to route a digital audio source from IN 4 (RGB) to the QM output, set the Control$ input to “I4O1A\r”. Alternatively, the command string can consist of 2-digit values, e.g.,“I04O01A\r”.

Any switches made to the microphone or audio inputs will use the current mixer settings.

NOTE: If an input greater than “5” or “05” is sent, the command is ignored. If an output destination less than or greater than “1” / “01” is sent to the MD5x1, the command is ignored.

When the verbose mode is on and the routing status changes while the MD5x1 is in the system mode, or if the MD5x1 is polled for the status of an output, the MD5x1 replies with one of the responses listed in the following table.

Switching/Routing Status Replies

MESSAGE DEFINITION

IxO1A\r

IxO1V\r

SA1V1M1\r Current switching schema of all of the outputs

If a switch command is sent and an output is already at the new setting, serial feedback will not be provided for that output.

New audio route if audio route has changed where x will be a two-digit number from 00 to

05. New video route if video route has changed

where x will be a two-digit number from 00 to

05.

where a1 is the input routed to the QM output audio channel, v1 is the input routed to the QM output video channel, and m1 is the microphone input routed to the QM output microphone channel. Each number will be two digits.

NOTE: There is no serial feedback for any switches made while the MD5x1 is in the local mode, even if the verbose mode is on. Use the LocalMode-FB digital signal to signal when the device leaves local mode in order to trigger the “S?\r” command to query the MD5x1 for the current status of all outputs.

“Switch All” Example

The string “C020401\r” sends the following command:

• Switch Audio Input 2, Video Input 4 and no microphone signal to QM Out.

If polled for the status of all outputs (S?\r), the device response on Control-FB$ will be: “S020400\r”.
