SW RGB and YUV A Switchers • Introduction1-2

Features

Audio switching models

Inputs — These switchers input 2, 4, or 6 stereo audio signals, balanced or

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

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

unbalanced, on a 3.5 mm, 5-pole captive screw terminal.

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, to
be compatible with a wide range of line level (from -20 dBV to +4 dBV).
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.

Introduction, cont’d

All models

Bandwidth — Bandwidth is 350 MHz (-3 dB). This high bandwidth allows the

switchers to switch all of the high-resolution video signals with no loss of
signal quality.

Input signal sensing — The switcher continuously monitors all inputs to sense

when the 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 continuously

monitors all inputs and automatically switches to the highest-numbered
input with video sync pulses present. If video is absent from all inputs, no
input is selected.

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

and attenuation for each input using the front panel buttons or via the
switcher’s Remote port RS-232 link. The RS-232 link allows remote control
via a PC or control system. The operator can select inputs via the switcher’s
contact closure link on the Remote port. The operator can also remotely
control the switchers using a contact closure keypad connected to the Remote
port or an Extron IR 102 Universal remote control kit (part #70-224-01)
connected to the Remote port.

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

supplied rack ears. The two SW2 models require an optional 1U Universal
Rack Mount Kit (part #60-190-01) for rack mounting.

Power supply — Includes an internal 100 VAC to 240 VAC, 50/60 Hz, 20 watts,

auto-switchable power supply, which provides worldwide power
compatibility.

7

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

Rack mounting the switcher

The SW2 switcher models are housed in half-rack width 1U high metal enclosures
that can be rack mounted with an optional 1U Universal Rack Mount Kit or 1U
Basic Rack Shelf (part #60-190-01 or 60-604-01). The SW4 and SW6 switcher models
are housed in rack-mountable, 1U high, 17" wide metal enclosures. The
appropriate rack mount kit is included with the SW4 and SW6 switchers. Rack
mount the switcher as follows:

SW2 models

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

2. Place the switcher on one half of the optional 1U (one unit high, 19" wide)

rack shelf (part #60-190-01). Align the front of the switcher with the front of
the shelf, and align the threaded holes on the bottom of the switcher with the
holes in the rack shelf (figure 2-1).

3. Secure the switcher to the rack shelf with the two provided 4-40 x 3/16"
machine screws. Insert the screws from the underside of the shelf, and
securely fasten them through diagonally opposite corners as shown in
figure 2-1.

4. Fasten the false front panel (provided with the rack shelf) to the unoccupied
side of the rack (as shown in figure 2-1), or install a second half-rack-width
device in that side by repeating steps 1 through 3.

5. Secure the rack shelf to the rack using four 10-32 x ¾" bolts. Insert the bolts
through #10 beveled washers, then through the holes in the rack ears.

SW4 and SW6 models

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

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

provided (figure 2-2).

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.

Switcher Operations

The following paragraphs detail the power up process and provide sample
procedures for selecting an input and viewing and adjusting the audio level.

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 LED for the previously selected
input lit and all other Input LEDs off.

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 computers
and scalers) 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

A new input can be selected using the front panel buttons. Select a new input as
follows:

3

Sales & Technical Support

1. Select the desired input by pressing the associated input button.

2. Observe that the LED for the selected input lights.

The switcher must be in normal (manual) mode.

An input can also be selected using an RS-232 device or a third party contact
closure device. See chapter 4, Remote Control. Separate video and audio inputs
(audio breakaway) can be established under RS-232 control. If audio is broken
away, the selected video input is indicated by a steadily lit input LED, and the
selected audio input is indicated by a blinking input LED.

Switching inputs on the front panel can only switch video and audio together
(audio follow). Even if audio was previously broken away, audio follows the
video on front panel input selection.

Audio gain and attenuation (SW2 RGBHV A, SW4 RGBHV A, and
SW6 RGBHV A only)

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.

The switcher must be in normal (manual) mode.

1. Press and release an input button to select an input.

Optimizing the Audio (SW2, SW4, and SW6 RGBHV A only)

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 Inputs and Output, in chapter 2,
Installation.

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.

Remote Control

The SW RGB and SW YUV A Series switchers can be remotely controlled via the
switcher’s rear panel Remote connector (figure 4-1). Remote control devices can
be:

• A host device (such as a computer or control system)

• An IR 102 Universal remote control kit

• A contact closure device such as an Extron KP 6 Keypad Control or a locally­constructed device.

Three remote control methods are available:

• Extron’s Simple Instruction Set

• Extron’s Windows-based control program

• Contact closure

Figure 4-1 — Remote connector pinout

The RS-232 protocol of the rear panel RS-232/Remote connector is a follows:

• 9600 baud • No parity

• 1 stop bit • No flow control

The cable used to connect the 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.

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 Simple Instruction
Set, for definitions of the SIS commands and Windows-Based Control Program 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 Contact Closure, for information on how to make
a remote contact closure device.

Simple Instruction Set

Host-to-switcher instructions

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 RGB and YUV A Switchers • Remote Control4-2

Switcher-initiated (unsolicited) 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 2002, Extron Electronics, SW6 RGBHV {or appropriate model}, Vx.xx
The switcher issues the copyright message when it first powers on. Vx.xx is the

firmware version number.

Inn•All
The switcher issues the Inn message when a front panel input selection operation

occurs. n is the input number.

Reconfig
The switcher initiates the Reconfig message when there is a change in an audio

model’s audio gain setting.

Sig•n•n•n•n•n•n
The switcher initiates the Sig message when there is a change in the status of an

input. n = 1 indicates a video signal is present, n = 0 indicates a video signal is not
preset. There are as many ns in the switcher-initiated message as the maximum
number of inputs for the models (2, 4, or 6). For example: Sig•1•1•1•0•1•0
which the input signal is present on inputs 1, 2, 3, and 5 and no signal is present on
inputs 4 and 6.

, in

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
E06
E09
E10
E13

- Invalid input channel number (out of range)

- Invalid input channel change (autoswitch mode active)

- Invalid function (mode) parameter

- Invalid command

- Invalid value (out of range)

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a
timeout. The command operation is aborted with no other indication.

Using the command/response table

The command/response table is on the next page. With the exception of the set
audio gain and attenuation commands (G and g) , the SIS commands are
sensitive. Symbols are used throughout the table to represent variables in the
command/response fields. Command and response examples are shown
throughout the table. The ASCII to HEX conversion table on the next page is for
use with the command/response table.

Windows-Based Control Program

The Universal Switcher Control Program, part #29-031-01, is compatible with
MicrosSoft 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)

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. Connect a serial cable between a PC and the switcher’s remote port. The
cable’s pin assignments are shown in figure 4-1 on page 4-2. Power up the PC
and the switcher.

2. To run the software, click on Start>Programs>Extron Electronics>Universal

Switcher Control Pgm.

3. Click on the COM port that is connected to the switcher’s RS-232 port.

4. The Extron Universal Switcher Control Program window (Figure 4-2) displays

the input signal status for each input (signal present or not present), the
selected input, and the audio gain for the selected input.

Figure 4-2 — Universal Switcher program window

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 Universal

• 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

The Remote connector also provides a way to select an input to the switcher by
using a remote contact closure device, such an Extron KP 6 Keypad Remote Control
or a locally-built 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.

Switcher Control Program Help icon.

Autoswitching models must be in normal (manual) mode.
