Inst allat ion 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 power.
· Check the cabling and make adjustments as needed. · Select a different input
that is known to work to check
for a display and sound.
M ount ing t he Sw it cher
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
before mounting the switcher. See “Identifying the Board Version and Setting
the SW VGA/Ars Jumpers” on page 2-10.
Rack m ount ing
UL guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the
installation of the switcher into a rack (figure 2-1).
1. Elevated operating ambient — 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. Reduced air flow — 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. Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — 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.
5. Reliable earthing (grounding) — Reliable earthing of rackmounted 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).

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 ( 6 on figure 2-3 and figure 2-4) and each VGA connector ( 2
and 4 on figure 2-3 and figure 2-4) on the rear panel of the switcher. Lift
the top cover off of the switcher.

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.

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

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:

Cont act Closure Rem ot e Cont rol
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.
