Introduction

Introduction, cont’d

Introduction

The Extron MAV Series switchers are broadcast quality matrix switchers that distribute any video and/or audio input to any combination of outputs. The MAV switchers can route multiple input/output configurations simultaneously. There are four matrix sizes available, each with unique features or optional capabilities:

• MAV 84 RCA (eight inputs by four outputs)

• MAV 128 RCA (twelve inputs by eight outputs)

• MAV 168 (sixteen inputs by eight outputs)

• MAV 1616 (sixteen inputs by sixteen outputs) The MAV 84 and MAV 128 input and output audio on RCA connectors.

Audio models in the MAV 168 and MAV 1616 series input and output audio on

3.5 mm, 5-pole captive screw terminals. The MAV 168 and MAV 1616 are available in models that can switch three video planes (component video), two video planes (S-video), or one video plane (composite) video, each with or without an audio plane. An audio-only matrix switcher is also available in the MAV 168 and MAV 1616 series.

MAV component video switchers can also route RGsB and RsGsBs video signals. 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.

MAV S-video switchers 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.

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

The MAV Series switchers are single-box solutions to simple 150 MHz (-3dB) routing applications (figure 1-1, figure 1-2, figure 1-3, and figure 1-4). Each input and output is individually isolated and buffered, and any inputs can be switched to any one or all outputs with virtually no crosstalk or signal noise between channels.

Turn on the input and output devices.

The image from each input device should appear on the output devices, and

you should be able to switch from one input device to another. If this does not happen, double check steps 3 through 5 and make adjustments as needed.

Mounting the Switcher

The MAV component video models are housed in rack-mountable, 4U high, 17” wide metal enclosures. The MAV S-video models are housed in 3U enclosures. The MAV composite and audio-only models are housed in 2U high, enclosures. The appropriate rack mount kit is included with each switcher. To rack mount the switcher, do the following:

1. Insert the switcher into the rack, aligning the holes in the mounting bracket

with those in the rack.

2. Secure the switcher to the rack using the supplied machine screws.

Cabling and Rear Panel Views

All connectors are on the rear panel. The switcher can connect to up to as many as 16 component video, S-video, composite video and/or stereo audio devices, depending on the model. The switcher can output to as many as 16 video and/or audio outputs, depending on the model. Figure 2-1 shows a MAV 1616 component video and audio switcher. Figure 2-2 shows a MAV S-video and audio switcher. Figure 2-3 shows a MAV 1616 composite video switcher without audio. MAV 168 switchers are housed in the same 2U, 3U, or 4U enclosures as their MAV 1616 counterparts of the same video and/or audio type, but have fewer output connectors to accommodate the different matrix sizes they provide. Figure 2-4 shows a MAV 1616 audio switcher. Figure 2-5 shows a MAV 128 RCA switcher.

Some devices, such as VCRs, can be connected to both input and output connectors of the switcher. Others, such as tape players or CD players, can be connected only to the audio input connectors. An audio device and a separate video device can share an input; the switcher is capable of switching video and audio separately (audio breakaway).

MAV Series Switchers • Installation2-4

The component video and S-video MAV 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 MAV 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. Ensure that the captive screw connector is plugged into the desired input or output.

Audio input connections

MAV 128 RCA — Each input has a pair (left and right) of RCA connectors. MAV 168/1616 — Each input has a 3.5 mm, 5-pole captive screw connector for

balanced or unbalanced stereo audio input. Connectors are included with each MAV Series switcher, but you must supply the audio cable. See figure 2-6 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

When making connections for the MAV Series Switcher from existing audio cables, see figure 2-7. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve. The ring, tip, and sleeve wires are also shown on the captive screw audio connector diagrams, figure 2-6 and figure 2-8.

The audio level for each input can be individually set, via the front panel or RS-232/RS-422, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

By default, the audio output follows the video switch. Audio breakaway, which is commanded via the front panel (see chapter 3) or under RS-232/422 control, via the SIS or Windows-based control program, allows you to select from any one of the audio input sources.

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 MAV 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 switcher switches between inputs, the resulting change in image should be seamless, or clean. Video models of the MAV 1616/168 Series switcher 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 2-9 shows a basic external sync configuration. The Ext Sync In connector receives a timing signal. The Out connector allows the signal to be passed on to another video device, if required.

MAV SERIES SWITCHER

COMPOSITE VIDEO

MAV SERIES SWITCHER

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 — Consists of one or more 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 sixteen

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

MAV Series Switchers • Operation3-2

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

Input 1 through 16 buttons and LEDs — The input buttons have two

independent functions: to select and identify an input and to select or identify a preset. A more detailed explanation of the two functions is included in Front panel operations, beginning on pages 3-4.

Output 1 through 16 buttons and LEDs — The output buttons and LEDs

select and identify outputs. As a secondary function 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 pages 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 (7) and (8)], press the desired input button (1), press the desired output buttons (2), 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. 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 (1) 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.

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 (7) and Audio (8) buttons.

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 pages 3-11 through 3-14.

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 lights for two seconds 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 pages 3-11 through 3-14.

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.

3-3MAV Series Switchers • Operation

Operation, cont’d

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 on audio models, 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 (5) and Esc (6) buttons. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on pages 3-11 through 3-14.

Front panel I/O label windows

Input and output label windows — These translucent panels can be removed

and replaced to insert labels behind the panels. To remove a panel, insert the Phillips-head end of an Extron tweaker or small Phillips-head screwdriver into the hole in one end of the panel, and gently slide the tab on the edge of the panel out of the recess in the switcher housing.

Input and output labels can be created easily with Extron’s Button Label Generator software, which ships with every Extron Matrix Switcher, or with any Brother P-Touch labeler. Each input and output can be labeled with names, alphanumeric characters, or even color bitmaps for easy and intuitive input and output selection (figure 3-3). See Chapter 5, Matrix Software, for details on using the label software.

Front Panel Operations

The following paragraphs detail the power up process and 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.

Rack DVD (DVS 100)

INP

7 8

MAV Series Switchers • Operation3-4

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 Hotline.

Creating a configuration

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

1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs

that may be on.

2. Select to configure video, audio, or both by pressing the Video and/or Audio

buttons.

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: 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.

Viewing a configuration

The current configuration can be viewed using the front panel buttons. The viewonly mode prevents inadvertent changes to the current configuration. View-only mode also provides a way to mute video and audio outputs (see Muting and unmuting video and/or audio in this chapter.

To view the current configuration, do the following:

1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs

that may be on.

2. Press and release the View button.

3. Select video, audio, or both to view by pressing the Video and/or Audio

buttons.

4. Select the desired input or output(s) for which ties need to be viewed by

pressing the input and output buttons.

1. To see all ties of the current configuration, press and release each input and output button, one at a time, with the Video and Audio LEDs on.

2. In view-only mode, you can view video and audio, video-only, or audioonly ties. Pressing and releasing the Video and Audio buttons toggles each on and off.

3. If, when you view video and audio ties, the Audio LED blinks and the Video LED is on after you select an input or output, the LEDs indicate that the audio ties are not the same as the video ties for that input (audio breakaway is active). Toggle the Video LED off by pressing and releasing the Video button.

4. When you enter view-only mode, the output LEDs turn on for all outputs without ties. Likewise, when an output button for which there are no ties is pushed, the output LEDs turn on for all outputs without ties. The blinking Audio LED indicates audio breakaway for one or more of those outputs.

Example 4: Viewing video and audio, audio only, and video only ties

See figure 3-8, figure 3-9, figure 3-10, and figure 3-11 and the following steps for an example of viewing the video and audio, audio-only, and video-only ties in the current configuration.

Using presets

The current configuration (configuration 0) can be saved as a preset in any one of 16 preset memory addresses.

Example 6: Saving a preset

See figure 3-13 and the following steps for an example of recalling a preset to become the current configuration.

1. Only the audio and video ties are stored and recalled; audio gain settings are not saved, and they do not change when a preset is recalled.

2. Presets cannot be viewed from the front panel unless recalled as the current configuration. Presets can be viewed using Extron’s Windowsbased control program. See Chapter 5 for more details.

3. The current configuration and all presets are stored in non-volatile memory. When power is removed and restored, the current configuration is still active and all presets are retained.

4. When a preset is recalled, it replaces the current configuration, which is lost unless it is also stored as a preset. The recalled preset overwrites all of the current configuration ties in favor of the preset configuration ties.

Troubleshooting

This paragraph gives recommendations on what to do if you have problems operating the MAV series switcher, 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

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.

Sales & Technical Support Hotline if necessary.

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 3-17 and use one for each preset configuration. The forms accommodate all of the MAV models. Cross off all unused or inactive inputs and outputs. Use different colors for video and audio.

Worksheet example 1: System equipment

Figure 3-19 shows a worksheet for a MAV 1616 in a fictional organization with the system hardware annotated. Inputs 10 and 11 and output 7 have no connections in this organization, so they have been crossed out on the worksheet.

Inputs include video cameras, audio tape and CD players, laser disc players, VCRs, and a VTG 200. Output devices include monitors, front and rear projectors, a stereo, and several VCRs.

Note that VCRs 1, 2, 3, and 4 are connected to inputs 13 – 16 and also to outputs 13 – 16. This arrangement is convenient for video editing applications. Connecting the VCR inputs and outputs to the same inputs and outputs on the switcher is not a requirement. They can be separated and spread around in any configuration

The Extron VTG 200 video test generator connected to input 12 enables a video test pattern to be sent to one, several, or all output devices for problem isolation or adjustment purposes. An audio test tape or CD could be used in a similar manner to check out the audio components.

Figure 4-1 — MAV switcher RS-232 connector pin arrangement

The MAV 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.

The RS-232/RS-422 connector on the MAV Series switcher is a 9-pin D female connector with the following pin assignments.

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.

MAV Series Switchers • Programmer’s Guide4-2

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

If an error occurs during powerup, 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. 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)

Matrix Software

Two software programs accompany the MAV Series switchers:

• The Extron Matrix Switcher+ 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 MAV 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 for details.

• The Extron Button-Label Generator allows you to design and print labels for the MAV 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).

This chapter describes both programs.

Matrix Switchers 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:\MTRX50 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 MAV Series switcher.

Using the software

Overview

This section is an overview of the Extron Matrix Control Program. The help function contains additional information. See Using the help system 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 for details.

The Extron Matrix Switcher+ Control Program window (figure 5-1 and figure 5-2) displays the current configuration of the attached matrix.

3. To set up audio in follow mode (audio and video have the same tie

configuration), select the Follow box at the bottom of the window. To set up audio in breakaway mode (audio and video have different tie configurations), deselect the Follow box.

Hardware Procedures

This appendix describes how to perform hardware upgrade procedures such as 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 (figure B-1).

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 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.

7. Attach the power cord to the switcher and to the AC power source. Ensure

the switcher is working properly.

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

switcher to the rack, and reconnect the power cord.

9. Reconnect the input and output cables.

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 for removing the

top cover, including the instructions for removing 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-2). 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 (see figure B-2).

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-3). Orient the IC to match the key and pin 1 (indicated by the arrow), and carefully press the IC in place.

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

9. Reinstall the cables that were removed in step 2 and 3. Ensure that the

RS-232/RS-422 ribbon cable is plugged into the proper receptacle for either RS-232 or RS-422, as appropriate.

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: a. Connect the power cord to the AC power source. b. Press and hold the Enter button while you connect the power cord to the

switcher.

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

To replace the AC fuse, do the following:

1. Follow the instructions in Opening the switcher on page B-2 for removing the top cover.

2. Locate the fuse on the power supply board (see figure B-2), and remove the fuse 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 as described in Closing the switcher on page B-3.

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.

Button Labels

Eight sets of button labels are provided on the next page. Feel free to cut them out of the manual, write button information in each button area as desired, and put them in the switcher’s label window.

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.
