Introduction

About the Matrix 50 Series Switchers

The Extron Matrix 50 Series Switchers are broadcast quality, upgradeable matrix switchers that distribute any video and/or audio input to any combination of outputs. The matrix switchers can route multiple input/output configurations simultaneously.

The modular Matrix 50 series are assembled from individual modules, each of which supports a discrete video or stereo audio plane, as follows:

• Composite video Matrix 50 switchers are assembled around one video module. The audio version of the composite video matrix requires a separate audio module.

• S-video Matrix 50 switchers are assembled around two video modules (one for the luma (Y) plane and one for the chroma (C) plane). The audio version of the S-video matrix requires a separate audio module.

Matrix 50 switchers with two video modules can also be used to switch two planes of composite video. If used in this way, the two planes cannot be broken away; both inputs must be routed to the same outputs.

• Component video Matrix 50 switchers are assembled around three video modules (one for the luma (Y) plane, one for the red minus luma (R-Y) plane, and one for the blue minus luma (B-Y) plane. The audio version of the component video matrix requires a separate audio module.

Component video Matrix 50 switchers can also route RGsB and RsGsBs video signals up to 150 MHz bandwidth. Switchers configured for component video can also route multiple composite video planes or S-video and composite video. If used in this way, the various planes cannot be broken away; all inputs must be routed to the same outputs.

• Audio only Matrix 50 switchers are assembled around one audio module for the stereo audio plane.

The video and audio modules are available with differing numbers of inputs and outputs to support four matrix sizes:

• Eight inputs by four outputs

• Eight inputs by eight outputs

• Twelve inputs by four outputs

• Twelve inputs by eight outputs

The audio switching can either be linked with the video (audio follow) or independent of the video (audio breakaway). Adjustable audio gain and attenuation compensates for level differences between audio inputs.

The Matrix 50 Series are expandable single box solutions to simple 150 MHz (-3dB) routing applications. Each input and output is individually isolated and buffered, and any input(s) can be switched to any one or all outputs with virtually no crosstalk or signal noise between channels.

The switchers are housed in rack-mountable, 2U high, 19” wide metal enclosures. The appropriate rack mounting kit is included with each switcher. Each model has an internal 100VAC to 240VAC, 50/60 Hz, 30 watts, auto-switchable power supply that provides worldwide power compatibility.

Figure 1- 1 — A typical Matrix 50 Series Switcher application

Inputs — These switchers offer 8 or 12 RGBS, RGsB, RsGsBs, HDTV, component

video, S-video, or composite video inputs on BNC connectors. Stereo audio can be balanced or unbalanced, on 3.5 mm, 5-pole captive screw

terminals (audio models).

Outputs — 4 or 8 RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or

composite video outputs are available on BNC connectors. Stereo audio, balanced or unbalanced, on 3.5 mm, 5-pole captive screw

terminals (audio models).

Bandwidth — Bandwidth is a minimum of 150 MHz (-3dB), fully loaded. This

high bandwidth allows the Matrix 50 switchers to switch everything from NTSC video to HDTV.

Operational flexibility — Operations such as input/output selection, setting of

presets, and adjustment of audio levels can be performed on the front panel or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote control via a PC or control system.

• QuickSwitch Front Panel Controller (QS-FPC™) — The Matrix 50 QS-FPC

feature supports touch-of-a-button input and output selection, preset creation and selection, and audio gain and attenuation control.

• Windows-based control program — Extron’s Windows-based control

program provides a versatile range of operational options with its graphical interface and drag-and-drop/point-and-click operation. The Windows-based

control program also has an emulation mode that lets you create a switcher configuration file at the home office and then download it for use by the switcher on site.

• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s SIS for easy programming and operation.

Audio gain/attenuation — Users can set the input level of audio gain or

attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front panel. Individual input audio levels can be adjusted so there are no noticeable volume differences between sources (figure 1-2).

Global memory presets — 12 global memory presets are a time-saving feature that

lets you set up and store input/output configurations in advance and then recall those configurations when needed with a few simple steps.

Switching flexibility — Individually buffered, independent matrix switched video

outputs with audio follow and audio breakaway for models with audio.

• Any input to any or all outputs

• Quick multiple tie — Multiple inputs can be switched to multiple outputs simultaneously. This allows all displays (outputs) to change from source to source at the same time.

• Audio follow — Audio can be switched with the corresponding video input. This feature allows any audio signal to be selected with any video signal simultaneously to one or all outputs in any combination. Audio follow switching can be done via front panel control or under RS-232/RS-422 remote control.

• Audio breakaway — Audio can be broken away from its corresponding video signal. Audio breakaway switching can be done via front panel control or under RS-232/RS-422 control.

Remote control — The Matrix 50 switchers are remote controllable, using the

MKP 1000 master control keypad and any combination of MCP 1000 slave control panels and/or MKP 1000 slave control keypads. The remote control devices are easy to use and provide tactile buttons for quick selection. Each MCP 1000 can be used for one-touch switching for a particular output and selecting global presets. Each MKP 1000 dedicated to an output can be used to select a different input for that output or to select a preset.

Matrix 50 Series Switchers • Introduction1-4

Labeling — Extron’s label software ships with every Extron matrix switcher. You

can create labels to place alongside the front panel input buttons and output buttons, with names, alphanumeric characters, or color bitmaps for easy and intuitive input and output selection. Alternatively, labels can be made with any Brother® P-Touch™ or comparable labeler.

Front panel security lockout — If a Matrix 50 Switcher is installed in an open area

where operation by unauthorized personnel may be a problem, a security lock-out feature can be implemented. When the front panel is locked, a special button combination is required to unlock the front panel controller before it can be operated.

Rack mounting — The switchers are mountable in any conventional 19” wide rack. Power — The internal 100VAC to 240VAC, 50/60 Hz, 30 watts, auto-switchable

power supply of the Matrix 50 Series provides worldwide power compatibility.

S-video outputs (two video module models only) — Connect S-video outputs to these BNC connectors for each output.

Composite video outputs (single video module models only) — Connect composite video outputs to these BNC connectors for each output.

The component video and S-video Matrix 50 Series switchers can also switch video lower on the video food chain by using only two or one BNC(s). If switching a different video format, ensure that the same video planes are used on the switcher output as on the input.

The Matrix 50 Series Switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

Audio input and output connections (audio models only)

The captive screw connector can easily be inadvertently plugged partially into one receptacle and partially into an adjacent receptacle. This misconnection could damage the audio output circuits. Exercise care to ensure the captive screw connector is plugged into the desired input or output.

Connections for balanced and unbalanced audio inputs — Each input has a

3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each Matrix 50 Series switcher, but you must supply the audio cable. See figure 2-5 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

If desired, attach an MCP 1000 remote control panel master unit to the switcher’s RS-232/RS-422 connector.

You can also connect an MKP 1000 remote keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to the MCP 1000 Remote Control Panel User’s Manual and the MKP 1000 User’s Manual for details.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and chapter 5, Matrix Software for details on how to install and use the control software.

The Matrix 50 Series Switchers are factory configured for RS-232 control. To use the switcher under RS-422 control, an internal cable must be moved. See appendix B for the procedure for shifting the cable.

External sync connection

When the switching between inputs, the resulting image change should be seamless, or clean. The Matrix 50 Series switchers can use an external signal to synchronize switching during the vertical interval. Without the external sync locking feature, switching between inputs can result in a brief rolling (sync loss) or a brief change in the picture size.

External Sync In connector — Connect an external sync signal to this BNC

connection for genlocking the video signal in broadcast or other sync-critical applications.

External Sync Out connector — Connect any downstream equipment that requires genlocking to this BNC connector to route the external sync signal throughout the system in broadcast or other sync-critical applications.

Figure 2-8 shows a basic external sync configuration. The Ext Sync In connector receives a timing signal. The Ext Sync Out connector allows the signal to be passed on to another video device, if required.

Figure 2-9 shows a configuration in which the timing source passes through three video cameras and a video scan converter before connecting to the switcher. This type of video camera is capable of synchronizing with the external timing source for video editing applications.

If no external sync timing source is connected to the switcher, switching occurs immediately.

Tie — An input-to-output connection. Set of ties — An input tied to two or more outputs. (An output can never

be tied to more than one input.) Configuration — May consist of one tie or one or more sets of ties. Current configuration — The configuration that is currently being used

(also called configuration 0). Global memory preset — A configuration that has been stored. Up to

twelve global memory presets can be stored in memory. The input buttons select the desired preset memory location to load or retrieve a preset. When a preset is retrieved from memory, it becomes the current configuration. One preset can be assigned to each input button.

Input buttons, output buttons, and LEDs

If the switcher has fewer inputs and outputs than input and output buttons and LEDs, only the applicable buttons and LEDs perform the function of selecting and identifying an input or output.

Input 1 through 12 buttons and LEDs — The input buttons have two

independent functions: to select an input and to select a preset. The input LEDs identify selected inputs. A more detailed explanation of the two functions is included in Front Panel Operations beginning on page 3-4.

Output 1 through 8 buttons and LEDs — The output buttons and LEDs

select and identify outputs. On audio models the output LEDs also display the user-adjustable audio level of the selected input. A more detailed explanation of the two functions is included in Front Panel Operations beginning on page 3-4.

Control buttons and LEDs

Enter button — The Enter button saves changes when you set up a new

configuration. To create a simple configuration, specify video, audio, or both [see I/O selection buttons ( press the desired output buttons (

Matrix 50 Series Switchers • Operation3-2

) and (8)], press the desired input button (1),

), and press the Enter button.

Preset button and LED — The Preset button saves a configuration as a

preset, or recalls and makes active a previously-defined preset. The Preset LED indicates save mode when it is blinking and recall mode when it lights steadily.

View button and LED — The View button selects a view-only mode that

allows the display of the current configurations and provides a way to mute and unmute video and audio outputs. The view-only mode helps prevent changing configurations by accident. The View LED indicates that the switcher is in view-only mode.

In view-only mode, pressing any input button (

) or output (2) button lights the LEDs for the input and all outputs that are a part of that set of ties. Pressing the button for any unassigned output lights only the LEDs for all of the unassigned outputs. No input LED is lit.

As a secondary function on audio models, the View button decrements the audio level of the selected input. In audio adjustment mode, the View LED indicates a negative (-) attenuation value. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on page 3-13.

Esc button and LED — The Esc button cancels operations or selections in

progress and resets the front panel LEDs. The Esc button does not reset the current configuration, the Video and Audio LEDs, any presets, or any audio gain/attenuation settings. The Esc LED flashes once after the Esc button is pressed and released to indicate the escape function.

As a secondary function on audio models, the Esc button increments the audio level of the selected input. In audio adjustment mode, the Esc LED indicates a positive (+) gain value. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on page 3-13.

I/O controls

When creating or viewing a configuration, you must specify whether the configuration applies to video, audio, or both. This is done with the Video ( and Audio (

)

) buttons.

Although present, the Audio button has no function on video only models.

Video button and LED — The Video button selects and deselects video for a configuration that is being created or viewed. The Video LED lights to indicate that video is available for configuring or for viewing.

Audio button and LED — The Audio button selects and deselects audio for a configuration that is being created or viewed. The Audio LED lights to indicate that the audio configuration follows the video configuration. The Audio LED blinks to indicate that the audio configuration is broken away from the video configuration.

As a secondary function, the Audio button selects the audio level display/ adjustment mode. Press and hold the Audio button until the Audio LED begins to blink. If the Video LED was lit, it turns off. Select an input. The current audio level setting for the selected input is displayed by the output LEDs. The audio level for the selected input can be increased and decreased by pressing the View (

) and Esc (6) buttons. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on page 3-13.

Front Panel Operations

The following paragraphs detail the power-up process and then provide sample procedures for creating ties, sets of ties, and configurations; changing a configuration; viewing ties, sets of ties, and configurations; muting and unmuting the video and audio; saving a preset; recalling a preset; and viewing and adjusting the audio level.

Power

On all models, power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test. An error-free power up self-test sequence leaves the Video and/or the Audio LED(s) on, depending on the model, and all other LEDs off.

The current configuration and all presets are saved in non-volatile memory. When power is applied, the last current configuration is retrieved. The previous presets remain intact.

If an error occurs during the self-test, the switcher locks up and will not operate. If your switcher locks up on power-up, call the Extron S Support Hotline.

Creating a configuration

The current configuration can be changed using the front panel buttons. To change the current configuration, do the following:

3. Select the desired input and output(s) by pressing the input and output buttons.

4. Press and release the Enter button.

5. Repeat steps 1 through 4 to create additional ties until the desired

configuration is complete.

1. Only one video input and one audio input can be tied to an output.

2. If a tie is made between an input and an output, and the selected output

was previously tied to another input, the older tie is broken in favor of the newer tie.

3. To indicate current ties, output LEDs light when an input is selected. To

clear unwanted outputs, press and release the associated output buttons.

4. If, when you configure video and audio ties, the Audio LED blinks and

the Video LED is on after you select an input or output, the LEDs indicate audio breakaway, meaning that the audio ties are not the same as the video ties for that input.

5. If an input with no tie is selected, only that input’s LED lights.

6. When the Video and Audio LEDs are on, if an input with an audio tie

but no video tie is selected, the input’s LED lights and the Audio LED blinks.

7. As each output is selected, the associated output LED blinks to indicate a

tentative tie. LEDs for output(s) that were already tied to the input light steadily. Outputs that are already tied can be left on, along with new blinking selections, or toggled off by pressing the associated output button.

Example 1: Creating a set of video and audio ties

See figure 3-3 and the following steps for an example in which input 5 is tied to outputs 3, 4, and 8 on a 12x8 Matrix 50 switcher with audio.

This example assumes that there are no ties in the current configuration.

Figure 3-3 — Example 1: Creating a tie

Press and release the Esc button. The Esc LED flashes once.

To select video and audio for the tie, if necessary, press and release the

Video and Audio buttons until the Video and Audio LEDs light.

System reset to factory defaults

To reset the switcher to the factory default settings, press and hold the Esc button on the front panel while AC power is being applied. Continue to hold the Esc button until the power-up sequence is completed (all LEDs turn off, the Video and Audio LEDs turn on, and the Esc LED blinks). System reset clears all ties and presets, and sets all audio gain levels to unity gain (+0dB).

Troubleshooting

This paragraph gives recommendations on what to do if you have problems operating the Matrix 50, and it provides examples and descriptions for some image problems you may encounter.

General checks

1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if one of the input LEDs is lit.

2. Ensure an active input is selected for output on the switcher.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

Sales & Technical Support Hotline if necessary.

Plasma display S-video problem

Extron has encountered a problem with the S-video output by some video conference codecs. Some codecs change the DC offset on the chrominance (C) so that it is very different from the level on the luminance (Y). This can cause a plasma display to come up in the wrong size mode.

With the matrix switcher taken out of the system, the plasma works fine. It looks like a Extron problem, but it is not. The matrix switcher boosts the bad codec output, which makes the plasma go to the wrong setting.

Solution: Try placing an Extron video DC block adapter, part #26-495-01, on the luminance (Y) input to the switcher from the codec.

Worksheets

Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-19 and use one for each preset configuration. The forms accommodate all Matrix 50 Series switcher configurations. Cross off all unused or inactive inputs and outputs. Use different colors for video and audio.

Programmer’s Guide

The switcher’s rear panel RS-232/RS-422 connector (figure 4-1) can be connected to the serial port output of a host device such as a computer, RS-232 capable PDA, or control system. This connection makes software control of the switcher possible.

Female

Male

Figure 4-1 — RS-232/RS-422 connector pin arrangement

The Matrix 50 Series switchers are factory configured for RS-232 control. To use the switcher under RS-422 control, an internal cable must be moved. See appendix B for the procedure for moving the cable.

The RS-232/RS-422 connector on the Matrix 50 Series switcher is a 9-pin D female connector with pin assignments as shown in figure 4-1.

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.

Host-to-Switcher Instructions

The switcher accepts SIS (Simple Instruction Set) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event such as a front panel operation occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below (underlined).

Vx.xx is the firmware version number. RECONFIG The reconfig message is initiated by the switcher when a front panel operation has

occurred, an audio gain adjustment has been completed, or a memory preset has been recalled.

RAM Test Failed ROM Checksum Failed EEPROM Reset (Presets/Attenuators) Serial EEPROM Reset (Current Settings) Invalid Jumpers

If an error occurs during power-up, the switcher initiates one or more of the messages listed above.

All Configuration Memory Cleared The memory cleared message is initiated by the switcher when a system reset has

occurred. See System reset to factory defaults in chapter 3.

Matrix 50 Series Switchers • Programmer’s Guide4-2

The switcher does not expect a response from the host, but, for example, the host program might request a new status.

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the switcher is unable to perform the command because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (too large) E10 — Invalid command E11 — Invalid preset number (too large) E12 — Invalid output number (too large) E13 — Invalid value (out of range) E14 — Illegal command for this configuration E17 — Timeout (only caused by direct write of global presets)

Using the Command/Response Table

The command/response table begins on the next page. Lower case letters are acceptable in the command field only where indicated. Symbols are used throughout the table to represent variables in the command/response fields. Command and response examples are shown throughout the table.

Matrix Software

Two software programs accompany the Matrix 50 Series switchers:

• The Extron Matrix Switchers Control Program (Extron part number 29-015-01), which communicates with the switcher via the RS-232/RS-422 port, provides an easy way for you to set up ties and sets of ties.

If your Matrix 50 Series switcher was previously set up for RS-232, and your computer comm port uses RS-422, you must change the switcher cabling to match the computer interface. See Appendix B, Reference Information for details.

• The Extron Button-Label Generator allows you to design and print labels for the switcher’s front panel buttons.

Both programs are compatible with Windows 95/98, Windows NT, Windows ME, and Windows 2000. Updates to these programs can be downloaded from the Extron Web site (http://www.extron.com).

Matrix Switcher+ Control Program

Installing the software

The program is contained on a set of 3.5-inch diskettes, and you should load and run the program from the hard drive.

To install the program from the floppy disks to the hard drive, run SETUP.EXE from the floppy disk and follow the instructions that appear on the screen. The program occupies approximately 3 MB (megabyte) of hard-drive space.

By default, the Windows installation creates a C:\MTRX directory, and it places two icons (Matrix Switcher+ Control Program and Matrix Switcher+ Help) into a group or folder named “Extron Electronics”.

The program was designed to control most Extron matrix switchers, but its operation will be limited to the features and configuration of your Matrix 50 Series switcher.

Using the software

Overview

This section is an overview of the Extron Matrix Switcher+ Control Program. The help function contains additional information. See Using the help system on page 5-5 for details.

1. To run the Matrix Switcher+ Control Program, double-click on the Matrix

2. Click on the comm port that is connected to the RS-232/RS-422 port of the

switcher. To set up the software without attaching the switcher to the computer, see Using emulation mode on page 5-5.

Hardware Procedures

This appendix contains procedures for performing hardware maintenance operations such as installing a Matrix 50 Option Kit, swapping the RS-232 and RS-422 ports, installing a new firmware update, and replacing the fuse.

Opening the switcher

Before you can perform any of the hardware upgrade procedures, you must open the switcher. To open the switcher, do the following:

1. Disconnect the power cord from the switcher.

2. If the switcher is rack mounted, remove the switcher from the rack and place

it on a clean workspace.

3. Remove the eight screws that secure the switcher’s top cover as shown in figure B-1.

receptacle, and press evenly until the receptacle tabs lock into place.

Self-latching receptacle

2. Place the top cover (and the front cover if a firmware upgrade was

performed) in place and replace all the screws that were removed in Opening the switcher on page B-2.

Installing and removing video and audio modules

The Matrix 50 Series switchers are field upgradeable. The following procedures guide you through the process of:

• Upgrading from composite video (one video module) to S-video (two video

modules) or HDTV/component video (three video modules)

• Upgrading from S-video (two video modules) to component video (three

video modules)

• Downgrading from any of the above configurations

• Adding or removing audio capabilities

• Changing to a different switching matrix configuration (from an 8 x 4

configuration to a 12 x 8 configuration, for example)

1. Audio modules are always installed on the bottom of the switcher chassis (figure B-2). Removing or installing an audio board cannot be accomplished with video modules in the way. If changing the audio configuration of your switcher, remove all video modules first.

2. Video planes in the Matrix 50 Series switcher are configured from the top down; if the switcher is configured for composite video, only the top video location is used; if configured for S-video, the top two locations are used.

3. When adding video modules, the new module(s) must be of the same matrix configuration (8 x 4, 8 x 8, 12 x 4, or 12 x 8) as the existing module(s).

Installing a firmware update

The IC that contains the firmware for the matrix switcher also contains the memory in which presets and audio levels are saved. When you replace the IC, these settings will be lost. You may want to record the presets and audio levels before you replace the IC.

To replace the firmware, do the following:

1. Follow the instructions in Opening the switcher on page B-2 to gain access to the interior of your switcher, including the instructions to remove the front panel.

2. Locate the RS-232/RS-422 ribbon cable that connects the front panel board to the rear panel RS-232/422 port (figure B-7). Note which receptacle on the front panel board that the cable plugs into, and remove the cable from its receptacle (see step 4 in Swapping the serial ports).

Do not touch the components inside the switcher without being electrically grounded. Electrostatic discharge (ESD) can damage ICs, even if you cannot feel, see, or hear it.

3. Unplug the power cable from the front panel board.

4. Place the front panel board, button side down, on a suitable workspace.

5. Locate IC U7 (figure B-7).

6. Use the PLCC IC puller to remove the existing firmware IC. Squeeze the tool

to align its hooks with the slots in opposite corners of socket

U7. Insert the hooks, squeeze gently, and pull the IC straight out of the socket. Set the IC aside.

7. Note the key (angled corner) of the new firmware IC and the dot on the underside that indicates pin 1 (figure B-8). Orient the IC to match the key and pin 1 (indicated by arrow) on the socket, and carefully press the IC in place.

8. Reinstall the power cable that was removed in step 3.

9. Reinstall the RS-232/RS-422 cable removed in step 2. Ensure the RS-232/ RS-422 ribbon cable is plugged back into the proper receptacle for the communications format desired (RS-232 or RS-422).

10. Reinstall the switcher’s front panel and cover. See Closing the switcher on page B-3.

If you choose to check for proper operation before putting the cover back on, ensure that tools and hands are outside the switcher and then perform step 11. After recognizing the new IC, the switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

11. Reinitialize the switcher to recognize the new IC as follows:

c. Observe that the Input, Output, Preset, View, and Esc LEDs all flash. d. Release the Enter button.

12. Ensure that the switcher is working properly.

13. If the switcher was removed from a rack, remove its power cord, reattach the

switcher to the rack, and reconnect the power cord.

14. Reconnect the input and output cables.

Replacing the AC fuse

The AC fuse on the power supply board is a user-replaceable component of the Matrix 50 Series switchers. To replace the AC fuse, do the following:

1. Follow the instructions in Opening the switcher on page B-2 to remove the top cover.

2. Locate the fuse on the power supply board (figure B-7), and remove it from its retaining clips.

3. If test equipment is available, you can check the fuse.

4. Place a new 2A/250V fast-blow fuse in the retaining clips.

5. Reinstall the switcher’s cover. See Closing the switcher on page B-3.

If you choose to check the switcher for proper operation before putting the cover back on, ensure that tools and hands are outside the switcher, and then connect the power cord to the unit and to an AC source. The switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

6. Attach the power cord to the switcher and to the AC power source. Make sure the switcher is working properly.

7. If the switcher was removed from a rack, remove its power cord, reattach the switcher to the rack, and reconnect the power cord.

8. Reconnect the input and output cables.

Setting the front panel jumper

If the front panel jumpers are set incorrectly (for example, if the matrix configuration was changed and the jumpers were not updated), when the switcher is powered up, it locks up and will not operate. If the switcher is connected to a PC or control system, it reports setting of the jumper as follows:

1. Follow the instructions in Opening the switcher on page B-2 to gain access to the interior of your switcher, including the instructions to remove the front panel.

2. Locate the front panel jumper (figure B-7).

3. Install the jumpers as appropriate to your Matrix 50 model (figure B-9).
