input signal is active or inactive. The switcher reports changes in the status of each input (active to inactive or inactive to active) on the RS-232 port.

Autoswitching mode — When autoswitching is enabled, the switcher

automatically switches to the highest-numbered input with video sync pulses present. If video is absent from all inputs, input 1 is selected.

External sync input and output connectors — Allow the switcher to use a black

burst (genlock) signal to synchronize switching during the vertical interval. This ensures glitch-free switching among multiple timed sources.

Audio switchers

Captive screw connector (A) models

Inputs — These switchers input 4, 6, 8, or 12 balanced or unbalanced stereo audio

signals, on 3.5 mm, 5-pole captive screw terminals.

Outputs — The selected audio input is split, buffered, and output as 2 balanced or

unbalanced audio signals, on 3.5 mm, 5-pole captive screw terminals.

RCA connector (A RCA) models

Inputs — These switchers input 4, 6, 8, or 12 unbalanced stereo audio signals on

left and right RCA connectors.

Outputs — The selected audio input is split, buffered, and output on 2 sets of

connectors.

• One balanced or unbalanced audio signal, on a 3.5 mm, 5-pole captive screw terminal.

• One unbalanced stereo audio signal on left and right RCA connectors.

All audio models

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

attenuation (-18 dB to +24 dB) via the RS-232 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) and for the best headroom and signal-to-noise ratio. This function also eliminates the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

SW AV Series Switcher • Introduction1-4

Audio follow — If the switcher is also a video model, audio can be switched with

the corresponding video input. Audio follow switching can be done via front panel control or under RS-232 remote control.

Audio breakaway — If the switcher is also a video model, audio can be broken

away from its corresponding video input signal. Audio breakaway switching can be done via front panel control or under RS-232 remote control.

Executive mode (front panel security lockout)— All switchers that route audio

have an executive mode that locks out the I/O (video/audio/video and audio) selection button, toggling between autoswitch and normal mode, and all audio gain and attenuation adjustments at the front panel. If a switcher is installed in an open area, where operation by unauthorized personnel may be a problem, the switcher can be placed in executive mode. When the front panel is locked, a special button combination is required to unlock the front panel controller before audio gain and attenuation can be adjusted locally.

When the front panel is locked out, audio gain and attenuation is still available via the RS-232 link.

All switcher models

Operational flexibility — The operator can select the input, set the audio gain and

attenuation for each input, set the switch mode, and toggle executive mode on and off using:

• Front panel controller — The SW AV series front panel controller supports

touch-of-a-button input selection, audio gain and attenuation control, switch mode selection, and executive mode selection.

• RS-232 control — The switcher’s RS-232 link on the RS-232 (SW 8 and SW 12

models) or Remote (SW 4 and SW 6 models) port. The RS-232 link allows remote control via a PC or control system.

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.

Simple Instruction Set (SIS™) — The Simple Instruction Set program

lets a host computer control the switcher with simple commands. Optional infrared remote control — The operator can also control the

switcher using Extron’s IR 102 Universal remote control kit (part #70-224-01) connected to the RS-232 or Remote port.

• Contact closure (4-input and 6-input models only) — The operator can

remotely control the SW 4 and SW 6 switchers using a contact closure keypad connected to the Remote port. The switcher’s contact closure link on the Remote port.

Rack mount — Rack-mountable in any conventional 19" wide rack with the

included rack ears.

Power supply — Includes an internal 100 VAC to 240 VAC, 50/60 Hz, 15 watts,

autoswitchable power supply, which provides worldwide power compatibility.

Installation Overview

To install an SW AV Series switcher, do the following:

Turn off the input and output devices, and unplug their power cords.

If desired, mount the switcher in a rack or under furniture (see Mounting the

Switcher below).

Connect the input and output devices to the switcher (see Cabling and Rear

Panel Views on page 2-3).

(SW 8 and SW 12 models) If desired, connect a computer or an RS-232

control system to the RS-232 connector (see Remote connection on page 2-6).

(SW 4 and SW 6 models) If desired, connect a computer, an RS-232 control system, an IR device (such as the IR 102 remote control kit), or a contact closure device (such as a KP 6 Keypad Remote Control) to the Remote connector (see Remote connection on page 2-6).

If desired, connect a black burst (genlock) signal to the external sync

connectors (see External sync connection on page 2-6).

Plug the switcher and, if appropriate, the input devices and output devices

into a grounded AC source.

Turn on the input and output devices.

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

you 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

Tabletop use

For tabletop use, affix a self-adhesive rubber foot to each corner of the bottom of the switcher.

Rack mounting the switcher

The SW AV switcher models are housed in rack-mountable, 1U high, 17" wide metal enclosures. The appropriate rack mount kit is included with each switcher. Rack mount the switcher as follows:

1. If feet were previously installed on the bottom of the switcher, remove them.

2. Attach the rack mount brackets to the switcher with the eight #8 machine

screws provided (figure 2-1).

3. Insert the switcher into the rack, align the holes in the mounting bracket with

those of the rack.

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

Furniture mounting the switcher

The SW AV switcher models can be mounted under a table or other horizontal surface with an optional Extron MBD 129 Through-Desk Mount Kit, part #70-077-02.

1. Secure the optional table/wall mounting brackets to the switcher with the

eight machine screws provided in the mounting kit (figure 2-1).

2. Hold the switcher with attached brackets against the underside of the desk or

other furniture. Mark the location of holes for screws on the underside of the desk.

3. Drill 1/4" (6.4 mm) deep, 3/32" (2 mm) diameter pilot holes in the table or

desk at the marked screw locations from the underside/inside (concealed side) of the furniture, where the switcher will be located.

4. Insert the four wood screws into the pilot holes. Fasten each screw into the

installation surface until just less than 1/4" of the screw head protrudes.

5. Align the installed screws with the slots in the mounting brackets, and place

the switcher against the surface, with the screws through the bracket slots.

6. Slide the switcher slightly forward or back, then tighten all four screws to

fasten it in place.

Cabling and Rear Panel Views

All connectors are on the rear panel. The switcher can be connected to up to 12 S-video, composite video and/or stereo audio devices, depending on the model. All switcher models output two parallel video and/or audio outputs. S-video models encode one of the two video outputs as composite video. RCA audio models output one of the stereo audio outputs, unbalanced or balanced, on captive screw connectors and the other audio output, unbalanced, on RCA connectors.

Figure 2-2 shows an SW 4AV composite video and audio switcher. Figure 2-3 shows an SW 12SVA RCA S-video and audio switcher. All of the switchers are housed in the same 1U enclosures, but have more or fewer input connectors to accommodate the different configurations they provide. The two switchers shown have all of the connector types that are available in the SW AV product family covered in this manual.

Some devices, such as VCRs, can be connected to both video input and audio input 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, although the switcher is capable of switching video and audio separately (audio breakaway).

Audio input and output connections (audio models only)

The audio level for each input can be individually set, via the front panel or RS-232, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, and chapter 4, Remote Control for details.

By default, the audio follows the video switch. Audio breakaway, which is commanded via the front panel (see chapter 3) or under RS-232 control via the SIS or Windows-based control program, allows you to select from any one of the audio input sources. See chapter 3, Operation, and chapter 4, Remote Control for details.

CAUTION

Balanced or unbalanced audio input connections (captive screw connector

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 (A) models only) — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each SW AV Series switcher, but you must supply the audio cable. See figure 2-4 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

SW AV Series Switchers • Installation2-4

Figure 2-4 shows three methods of wiring the captive screw audio connectors for input and figure 2-5 shows two methods of wiring the connectors for output. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve. If wiring a captive screw connector from an existing unbalanced audio cable, the white insulated wire is typically the left channel (tip) and the red insulated wire is typically the right channel (sleeve). There is no reliable standard for existing balanced audio cables.

RS-232/Remote connector — Connect a host device, such as a computer or

touch panel control, or an IR remote control or a remote contact closure device (SW 4 and SW 6 models only) to the switcher via this 9-pin D connector (figure 2-6) for remote control of the switcher.

For RS-232 control and IR control, use a control cable with only pins 2, 3, and 5 connected. Otherwise, either cut the wires to the other pins in hard-shelled connectors or remove the unneeded pins from molded plugs. See chapter 4, Remote Control, for definitions of the SIS commands and details on how to install and use the control software.

For contact closure, use a control cable with pins 2 and 3 NOT connected. Otherwise, either cut the wires to these pins in hard-shelled connectors or remove these pins from molded plugs. See chapter 4, Remote Control, for information on how to make a remote contact closure device.

Female

The cable used to connect the RS-232/Remote port to a computer, control system, contact closure device, or IR control kit may need to be modified by removing pins or cutting wires. If unneeded pins are connected, the switcher may hang up.

External sync connection

When the switcher switches between inputs, the resulting change in image should be glitch-free, or clean. Video models of the SW AV 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.

Sync In connector — Connect an external genlock signal to this BNC

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

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 2-7 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.

Audio switchers have audio gain and attenuation adjustments. In executive mode, front panel adjustment of the audio level is locked. The level cannot be adjusted from the front panel until the panel is unlocked. See Executive mode in this chapter.

Audio gain and attenuation adjustments are still available via the RS-232 link when the switcher is in executive mode.

Mode button — The Mode button is used with the Executive mode button to

toggle executive mode on and off. See Executive mode (front panel security lockout) in this chapter.

This button is a secondary function of the Input 1 button.

Executive Mode button (unlabeled) — The Executive mode button is an

unlabeled secondary function of the Input 4 button. Executive mode is used with the Mode button to toggle executive mode on and off. See Executive mode (front panel security lockout) in this chapter.

Executive Mode LED — The Executive Mode LED indicates that the switcher

is in executive mode, and that the front panel I/O button and all audio gain and attenuation adjustments are locked.

This LED will never light on audio-only switchers.

Front Panel Operations

The following paragraphs detail the power up process and provide sample procedures for switching inputs, viewing and adjusting the audio level, changing between normal and autoswitch mode, and toggling executive mode on and off.

Power

Plug in the switcher. On all switcher 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 Auto Switch Active, Executive Mode, Video, Audio, and Input LEDs on or off in the same configuration as they were when power was last removed.

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.

Plug in all system components and turn on the input devices (such as DVD players, laserdisc players, VCRs, and DSS receivers) and the output devices. Set the input devices to output video using each device’s own operating instructions. Select an input. The image should appear on the screen. If no image appears, see Troubleshooting — If No Image Appears, in this chapter.

Switching inputs

An input can be selected for output using the front panel buttons. In switchers with both video and audio, the audio input can switch with the video input (audio follow) or either can be switched separately (audio breakaway). Select an input as follows:

Adjusting audio gain and attenuation (audio switchers)

Audio switchers have audio gain and attenuation adjustments. The audio level of each input can be adjusted through a range of -18 dB to +24 dB to ensure that there is no noticeable volume difference among sources and to eliminate the need for separate preamps or attenuators when used with professional (higher line level) and consumer (lower line level) audio equipment.

The audio level can be adjusted from the front panel or by using Extron’s Windows-based control program.

Video switchers must be in normal mode.

Switch mode

Video switchers support autoswitch mode. In autoswitch mode, the switcher automatically switches to the highest-numbered input with video sync signals present. Input selection, by the front panel buttons or the RS-232/Remote port, is blocked while in autoswitch mode. However, the front panel LEDs remain functional and the Input 1 through Input 3 buttons can be used to view or change the mode.

Turn autoswitch mode on as follows:

1. Press and hold the Mode (Input 1) button.

2. Press and release the Auto (Input 3) button. The Auto Switch Active LED

Executive mode (front panel security lockout)

Audio switchers have an executive mode that limits the operation of the SW AV switcher from the front panel. When the switcher is in executive mode, the I/O button (video/audio/video and audio selection), toggling between autoswitch and normal mode, and all of the front panel audio gain and attenuation functions are disabled.

Toggle executive mode on and off as follows:

1. Press and hold the Mode (Input 1) button.

2. Press and release the Input 4 button. The Executive Mode LED changes state.

If executive mode was off, the LED turns on to indicate that the switcher has entered executive mode.

If executive mode was on, the LED turns off to indicate that the switcher has left executive mode.

3. Release the Mode button.

Memory

Audio and mode settings are saved in nonvolatile memory. When the switcher is powered off, the settings are retained. When the switcher is powered on, the saved memory settings are active. The selected input is not a saved value; when the switcher is powered on it, defaults to input 1.

If a video switcher is powered off in auto mode, it automatically switches to the highest-numbered input with video sync pulses present when it is powered back on. If no input has video present, all input select LEDs are off (only the Power LED is on, if equipped).

Optimizing the Audio (Audio Switchers)

Each individual input audio level can be adjusted within a range of -18 dB to +24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows:

1. Connect audio sources to all desired inputs and connect the audio outputs to

output devices such as audio players. See Audio input and output connections (audio models only), in chapter 2, Installation. For best results, wire all of the inputs and the outputs unbalanced.

2. Power on the audio sources, the switcher, and the audio players.

3. Switch among the inputs (see Switching inputs, in this chapter), listening to the

audio with a critical ear or measuring the output audio level with test equipment, such as a VU meter.

4. As necessary, adjust the audio level of each input (see Adjusting audio gain and

attenuation (audio switchers), in this chapter) so that the approximate output

level is the same for all selected inputs.

SW AV Series Switchers • Operation3-12

Troubleshooting — If no Image Appears

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 on the switcher or that the switcher is in

autoswitch mode.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

Simple Instruction Set Control

Host-to-switcher communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the switcher to the host end 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.

SW AV Series Switchers • Remote Control4-2

Switcher-initiated messages

When a local event occurs, such as a front panel operation, loss or restoration of an input signal, or an error condition, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below:

powers on. Vx.xx is the firmware version number. Cn identifies the currently selected input, where n is the input number (input 1 is the power-up default in normal mode). The switcher also sends the Cn input is changed using the front panel buttons.

Sig n n n n n n A video switcher initiates this message when there is a change in the status of a

video input. Each n indicates an input (1 through last, from left to right). n = 1 indicates video signal present, n = 0 indicates video signal not preset. There are as many ns in the switcher-initiated message as the maximum number of inputs for the models (4, 6, 8, or 12).

Reconfig

The switcher initiates the Reconfig message when there is a change in an audio model’s audio gain setting.

Error responses

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

E01 E10 E13 E14

– Invalid input channel number (out of range) – Invalid command – Invalid parameter (out of range) – Illegal command for this configuration

Windows-Based Program Control

The Universal Switcher Control Program, part #29-031-01, is compatible with Windows 3.1, 3.11, 95/98, and above, and provides remote control of the following:

• Input selection (including audio breakaway for models with video and audio)

• Audio gain and attenuation adjustments (audio models)

• Front panel switch mode selection (autoswitching models)

Updates to this program can be downloaded from the Extron Web site (http://www.extron.com).

Installing the software

The program is contained on two 3.5" diskette and must be installed and run from the hard drive.

To install the software on the hard drive, run setup.exe from floppy disk #1 and follow the screen instructions.

By default, the Windows installation creates a C:\UNIVSW folder and places two icons (Universal Switcher Control Program and Universal Switcher Help) into a group named “Extron Electronics”.

Using the software

1. To run the software, double click on the Universal Switcher Control Program

icon in the Extron Electronics program group.

2. Click on the comm port that is connected to the switcher’s RS-232 port.
