The switchers are compatible with NTSC, PAL, and SECAM
video. If external sync is connected, video switching occurs
during the vertical interval, providing glitch-free switching.

The switchers allow the user to switch between devices, such as
a DSS receiver, a VHS or S-VHS VCR, a DVD player, or a
camcorder and output the image to one or two video recorders
or displays such as a data monitor or large screen projector
(figure 1-1).

The ½-rack width switcher can be mounted to a standard Extron
rack panel (part # 60-190-01). Each model has an internal
100VAC to 240VAC, 50/60 Hz, 10 watts, auto-switchable power
supply that provides worldwide power compatibility.

Each input has a 3.5 mm, 5-pole captive screw
connector for balanced or unbalanced stereo
audio input. Connectors are included with
each A/V 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.

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.

External sync connection

When the switching between inputs, the resulting image change
should be seamless, or clean. The A/V 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 2-7 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.

Select an input. The image should appear on the screen.

Selecting an input

To select an input using the front panel buttons, press and
release the button for the desired input (auto-sync detect
models must be in normal mode). The LED for the selected
input lights.

Input selection can also be done by an RS-232 device or a third
party contact closure device (see chapter 4, RS-232/Remote
Control).

Normal and auto-sync mode

The auto-sync detect model can operate in either normal
(manual switch) or auto-sync mode. Input selection by the front
panel buttons is blocked while in auto-sync mode. However,
the front panel LEDs remain functional and the buttons can be
used to view or change the mode.

Viewing the current switch mode

The current mode can be determined at any time by pressing
and holding the input 1/Mode button until either the
input 2/Norm or input 3/Auto LED blinks to indicate the
mode. Release the input 1/Mode button.

Conversely, if selecting input 1 and the input 1/Mode
button is held too long, the current mode is displayed
and input 1 is not selected.

Selecting normal mode

Press and hold the input 1/Mode and input 2/Norm buttons
simultaneously. The input 2/Norm LED blinks to indicate
normal mode. Release both buttons. The default input is
input 1, but if you release the input/Mode 1 button before
releasing the input 2/Norm button, the switcher may select
input 2.

When changing mode, if the input 1/Mode button is
released too soon (before the input 2 or 3 LED begins to
blink), input 1 may be selected.

Selecting auto-sync mode

Press and hold the input 1/Mode and input 3/Auto buttons
simultaneously. The input 3/Auto LED blinks to indicate auto­sync mode. Release both buttons. The highest-numbered input
with video sync pulses present is automatically selected for
output. If no sync is present, no input is selected.

When changing mode, if the input 1/Mode button is
released too soon (before the input 2 or 3 LED begins to
blink), input 1 may be selected.

Audio gain and attenuation

The audio level of each input can be displayed and adjusted
through a range of -15dB to +9dB to ensure that there is no
noticeable volume difference among sources. The audio level
can be adjusted from the front
panel or by using Extron’s
Windows-based control program.

1. Press and release an input

button to select an input.

Auto-sync detect models
must be in normal mode.

2. Press and hold the Audio

button until the Audio LED
begins to blink, then release
the Audio button. The audio
level for the selected input is
displayed in the input 1
through 5 LEDs and the
polarity (+ or -) is displayed
by the +dB and -dB LEDs.

Each input LED indicates 0dB
when off, 1dB when blinking
slowly, 2dB when blinking
quickly, and 3dB when lit.

The +dB LED on indicates a

To reset the audio level to 0dB for all inputs, press and hold the
Audio Conf./Save button for approximately 10 seconds. The
Audio LED begins to blink and then turns off. Release the
Audio Conf./Save button.

Memory

Audio and switch 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 an auto-sync detect model switcher is powered off in
auto mode, it automatically switches to the highest­numbered 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).

Troubleshooting — If no image appears

1. Ensure that all devices are plugged in and powered on.

The switcher is receiving power if the front panel Power
LED is lit.

2. Ensure an active input is selected on the switcher or that

the switcher is in auto-sync mode.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S3 Sales & Technical Support Hotline if

necessary.

Simple Instruction Set Control

Host-to-interface 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.

1#nI 1#tupnI

2#nI 2#tupnI

3#nI 3#tupnI
4#nI 4#tupnI
5#nI 5#tupnI
6#nI 6#tupnI

Switcher-initiated messages

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

(C) Copyright 1996, Extron Electronics AV Series, Vx.xx
Cn

The switcher issues the copyright message and input selected
message when it first 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 message whenever
the selected input is changed using the front panel buttons.

Reconfig
The switcher initiates this 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:

- Invalid input channel number (out of range)

E01
E06

- Invalid input channel change (auto-switch mode
active)

- Invalid function (mode) parameter

E09
E10

- Invalid command

- Invalid value (out of range)

Timeout

Pauses of 10 seconds or longer between command ASCII

Windows-Based Program Control

The Universal Switcher Control Program, part #29-031-01, is
compatible with Windows 3.1/3.11, Windows 95/98, Windows
NT, Windows ME, and Windows 2000 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 (auto-switching
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 a single 3.5” diskette and can be
run from the floppy drive, or it can be installed and run from
the hard drive.

To install the software on the hard drive, run setup.exe from the
floppy disk 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.

3. The Extron Universal Switcher Control

Program window (Figure 4-2) displays the
selected input, the audio gain for the selected
input, and the panel mode.

Figure 4-2 — Universal Switcher program window

Using the help system

For information about program features, you can access the help
program in any of the following ways:

• From the Extron Electronics program group, double-click on
the Signal Enhancement Products Help icon.

•From within the Windows-based switcher

control program, click on the Help entry on
the task bar.

•From within the Windows-based switcher

control program, press the F1 key.

Contact Closure Remote Control

The Remote connector also provides a way to select an input to
the switcher using a remote contact closure device. Contact
closure control uses pins on the Remote connector that are not
used by the RS-232 interface. The contact closure pin
assignments are shown in the table on page 4-2.

To select a different input number using a contact closure
device, momentarily short the pin for the desired input number
to logic ground (pin 5). To force one of the inputs to be always
selected, leave the short to logic ground in place. The short
overrides front panel input selections.

Shorting the contact closure pin to override the front
panel selection will work for all inputs on non auto­switching models. On auto-switching models, only the
contact closure pins for inputs 2 through 6 can be
shorted in this fashion. If pin 1 is connected to ground
for an extended period on an auto-switch model, input 1
is not selected. Rather, the LEDs alternately display the
previously selected input and blink the current front
panel mode.

Infrared Remote Control

The optional Extron IR 20 Universal SYS 4/8/10/AV consists of
the following components:

• System remote (hand-held remote control)

• IR detector with 6’ cable and RJ-11 connector

•IR-20 SYS 4/AV switcher remote adapter with 3’ cable and
RS-232 T connector

• External 9 VDC adapter power supply
