Mounting the Switcher
If you are going to connect VSW I AAP remote controls
to one or more inputs, identify the version of the
SW VGArs / Ars circuit board (to ensure that the
VSW I AAPs will work with this version) and configure
the switchers’ jumpers
. See “Identifying the Board Version and
Setting the SW VGA/Ars Jumpers” on page 2-10.
Rack mounting
UL guidelines
The following Underwriters Laboratories (UL) guidelines
pertain to the installation of the switcher into a rack (figure 2-1).
1 — If installed in a closed or
multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than
room ambient. Therefore, consider installing the equipment
in an environment compatible with the maximum 122 °F
(50 °C) ambient temperature (Tma) specified by Extron.
2 — Installation of the equipment in a rack
should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
3 — Mounting of the equipment in the
rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
4 — Consideration should be given to
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.
— Reliable earthing of rack-
mounted equipment should be maintained. Particular
attention should be given to supply connections other than
direct connections to the branch circuit (such as the use of
power strips).
Installation Overview
To install and set up the SW VGArs / Ars Series switchers,
follow these steps:
1
Turn all of the equipment off. Ensure that the video and
audio sources (computers, stereos, tape decks or other
devices), the SW VGArs / Ars switcher, the output devices
(projectors, speakers), and contact closure control device
are all turned off and disconnected from the power source.
2
If you are going to connect VSW I AAP remote controls to
one or more inputs, identify the version of the
SW VGArs / Ars circuit board (to ensure that the
VSW I AAPs will work with this version) and configure
the switcher’s jumpers. See “Identifying the Board
Version and Setting the SW VGA/Ars Jumpers” on
page 2-10.
3
Mount the switcher. See “Mounting the Switcher” on the
next page.
4
Attach the cables. See “Rear Panel Features and
Connections” later in this chapter.
5
Connect power cords and turn on the devices in the
following order:
• Output devices (projectors, monitors, speakers)
• SW VGArs / Ars Series switcher
• Contact closure/RS-232 controller
• Input devices (computers, audio sources)
6
Select an input using the front panel buttons, or the
contact closure or RS-232 controller.
7
The picture should now appear and sound should be
audible (SW VGA Ars models). If not:
• Ensure that all devices are plugged in and receiving

Identifying the Board Version and
Setting the SW VGA/Ars Jumpers
If you plan to use the switcher with VSW I AAP remote
controls, you must configure the switcher. It is more
convenient to do this before installing it in a rack or
furniture and making connections.
Using the SW VGA/Ars switcher with VSW I AAP control
panels requires you to set internal jumpers in the switcher.
When you open the switcher, you can also check the circuit
board installed in the switcher to ensure that it is compatible
with the VSW I AAP control panels.
On the VSW I AAP remote control, ensure that
jumper J6 is installed. Refer to the VSW I AAP manual
for details.
1. If applicable, disconnect all power to the switcher and any
attached devices.
2 Remove the eight screws from the switcher (three on each
side of the switcher and two on top) (figure 2-8). Remove
the two connector nuts from the Remote connector (

Configuring the switcher
There are six jumpers on the circuit board, numbered JMP5,
JMP7, JMP9, JMP11, JMP 13, and JMP15, that control connection
with one or more VSW I AAP control panels (figure 2-9 and
figure 2-10).
OPEN CLOSED
All jumpers are set open (removed) by default.
The jumpers in the table below must be set closed
(installed) when a VSW I AAP is connected to the

These jumpers enable/disable VGA connector pin 5 (control) for
each input. Close (install) the jumper for a specific VGA input
to allow the VSW I AAP’s “show me” signal to select that input.
When an input is not connected via a VSW I AAP, that
input’s jumper should be in the default (open) position.
Each jumper, when closed (installed) allows the switcher to
receive the “show me” signal from the VSW I AAP on that
input’s VGA connector. When a jumper is open (removed) that
input cannot receive the signal.
Auto switch mode must be disabled when using the
switcher with one or more VSW I AAP remote controls.
If the auto switch mode is enabled, the input cannot be
selected using the “show me” function.

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.
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 SWy VGArs, 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 this message when there is a change in an
audio model’s audio gain setting.
Sig•n•n•n•n•n•n
The switcher initiates this message when there is a change in the
status of an input. n = 1 indicates the video signal is present,
n = 0 indicates the video signal is not present. 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, the
response Sig•1•1•1•0•1•0
shows that the input signal is
present on inputs 1, 2, 3, and 5, and that no signal is present on
inputs 4 and 6.
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 — Invalid input channel number (out of range)
E06 — Invalid input channel change (auto-switch mode
active)
E09 — Invalid function (mode) parameter
E10 — Invalid command
E13 — Invalid value (out of range)
E14 — Illegal command for this configuration

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 figure 4-1 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.
IR 102 Infrared Remote Control
The optional Extron IR 102 kit consists of the following
components:
• IR 102 handheld remote control unit
• VersaTools IR 102 remote receiver with 3-foot cable and
RS-232 connector
• IR detector with 6-foot cable and captive screw connector
• External 12 VDC power supply
Install and operate the remote control in accordance with the
IR 102 User’s Guide included with the remote.
