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 I/O cables on the peripheral devices. Shielded cables must be used to ensure

compliance with FCC emissions limits.

• For more information on safety guidelines, regulatory compliances, EMI/EMF compatibility, accessibility, and related

topics, see the Extron Safety and Regulatory Compliance Guide 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 Setting the VSW2VGAA Jumpers on

page4).

3. If desired, mount the switcher (see Mounting the VSW2VGAA on page9).

4. Attach the cables (see Front Panel Features below and Rear Panel Features on the next page).

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.
