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.
FCC Class A Notice
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part15 of the
FCC rules. The ClassA limits provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used
in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause interference. This interference must be corrected at the expense of the user.
NOTES:
• This unit was tested with shielded ables on the peripheral devices. Shielded cables must be used to ensure I/O c
compliance with FCC emissions limits.
• For more information on safety guidelines, regulatory compliances, EMI/EMF compatibility, accessibility, and related
topics, see the on the Extron website.

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.

Installation Overview
To install and set up the VSW2VGAA for operation, follow these steps:
1. Turn all of the equipment off. Make sure that the video and audio sources (computers, stereos, DVD players, or other
devices), the VSW2VGAA, the output devices (projectors, speakers), and the contact closure control device are all turned off
and disconnected from the power source.
2. 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 conguring the VSWIAAPs) and congure the switcher jumpers (see on
Setting the VSW2VGAA Jumpers
page4).
3. If desired, mount the switcher (see on page9).Mounting the VSW2VGAA
4. Attach the cables (see Front Panel Features below and on the next page).Rear Panel Features
5. Connect power cords and turn on the devices in the following order: output devices, contact closure controller, VSW2VGAA
switcher, and input devices.
6. Select an input using the front panel input toggle switch or the contact closure controller.
7. The image should now display, and sound should be audible. If not, ensure that all devices are plugged in and receiving
power. Check the cabling and make adjustments as needed. Select a different input to check for a picture and sound.
