VSW2VGAA • User Guide
The Extron VSW2VGAA is a compact and economical two-input, one-output VGA
switcher with unbalanced stereo audio and 300 MHz (-3 dB) video bandwidth. It
accepts two VGA-UXGA, RGBHV, RGBS, RGsB, RsGsBs, component video, or
HDTV component video inputs. The switcher has two unbalanced stereo audio
inputs and one unbalanced stereo audio output. It also features a buffered local
monitor output for Input 1. A front panel toggle switch, a contact closure controller,
or the autoswitching option can be used for input selection.
This guide contains information about the Extron VSW2VGAA switcher. The
terms “VSW2VGAA” and “switcher” are used interchangeably in this manual.
The Extron VSWIAAP interface, an optional accessory used when several
VSW2VGAA switchers are daisy chained together, is also discussed.

Application Diagram
Up to 10 VSW2VGAA switchers can be daisy chained
together with each switcher input separately fed and
controlled by an optional accessory interface, the VSWIAAP.
Figure 1 is an example of how several such switcher-interface
combinations can be daisy chained together in a boardroom
environment.
By default, all switchers are set to input 2 as the active input.
Therefore, in a daisy chain of switchers the VGA and audio
signals ow from one switcher to input 2 of the next switcher
in the chain. The switchers are daisy chained in this fashion
until the last switcher in the daisy chain outputs to a projector
and audio amplier.
Up to ten switchers can be daisy chained together without
any degradation in picture quality. One power supply powers
up to ve switchers.

• Autoswitching —
NOTES:
• Autoswitch mode must be disabled when daisy chaining VSW2VGAA switchers. If the autoswitch mode is
enabled, the switchers cannot be daisy chained.
• RGsB and RsGsBs inputs and outputs occur in manual mode only.
• Autoswitching requires TTL level sync on pin 13 of the 15-pin HD connector.
Pins 1, 2, and Ground when jumpered and shorted together (as shown at right) turn the autoswitching mode on.
When the autoswitching mode is on, the switcher automatically switches to the input that has an active sync
signal.
If both inputs have an active sync signal present, input 2 is selected, and the input 2 LED indicator lights. If no
active sync signal is present, the input 1 LED indicator still lights to indicate that the unit is still powered on.
NOTE: When autoswitch mode is active, both daisy chaining and the front panel input toggle switch are disabled,
and the input cannot be manually switched. Any attempt to toggle the switch while the switcher is in this
mode results in the flashing of the currently active input LED indicator. Contact closure is also disabled while in
autoswitch mode.
Setting the VSW2VGAA Jumpers
NOTE: If you plan to use the VSWIAAP and create a daisy chain configuration, you must configure the switchers before
installing them in a rack or furniture and making connections.
Daisy chaining VSW2VGAA switchers requires you to check, set or both internal jumpers in the switcher.
1. If applicable, disconnect all power to the switcher and any attached devices.
2. Remove the two screws on each side of the switcher (see figure6). Remove the four connector nuts on the front panel of the
switcher. Lift the top cover off of the switcher.

Mounting the VSW2VGAA
ATTENTION: Installation and service must be performed by authorized personnel only.
ATTENTION : L’installation et l’entretien doivent être effectués uniquement par un électricien qualié.
NOTE: If you are going to daisy chain two or more switchers with VSWIAAP control panels, identify the revision of the
VSW2VGAA board (for configuring the VSWIAAPs) and configure the switcher jumpers before mounting the switchers
(see Setting the VSW2VGAA Jumpers on page4).
The VSW2VGAA can be mounted in a rack, or under or through furniture, using an optional mounting kit available at
www.extron.com. When mounting the switcher, take cabling and power availability into consideration. Follow the appropriate
mounting procedure on the following pages.
Rack Shelf Mounting
UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the VSW2VGAA in a rack.
1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient temperature. Therefore, install the switcher in an
environment compatible with the maximum ambient temperature (Tma = +122° F, +50° C) specied by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air ow required for safe operation of the
equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven
mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might
have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
13
10
VSW2VGAA • User Guide (Continued)
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply
connections other than direct connections to the branch circuit (e.g. use of power strips).
Rack mounting instructions
1. If feet were installed on the bottom of the switcher, remove them.
2. Mount the VSW2VGAA on a rack shelf. On the standard rack shelf, the switcher mounts in one of four locations to the rear
of the rack or in one of four locations to the front of the rack.
3. Attach the switcher to the rack shelf using two 4-40 x 3/16 inch machine screws. Insert the screws from the underside of the
