Chapter 2: Overview
2. Overview
2.1 Introduction
The 4- and 8-Port VGA Switches enable users to quickly and easily share a single
VGA display with several sources from your device inputs to one output device
(monitor, projector, or TV). You can select the desired input source via the remote
control within the range of 15 feet (5 m) or by using a push button on the switch.
Because you don’t need to plug and unplug video sources, it’s more convenient,
more affordable, and more efficient to use your A/V equipment.
The built-in serial interface on the AVSW-VGA4X1A and AVSW-VGA8X1A also
enables users to control the unit via an RS-232/serial device.
2.2 Features
• Switch between (4) or (8) sources.
• Switch audio and video.
• Use front-panel buttons for easy switching.
• Supports IR remote control.
• Supports serial remote control.
• LEDs show the status of input video and audio.
• Supports VGA monitors at resolutions up to 1920 x 1200.
2.3 What’s Included
Your package should contain the following items. If anything is missing
or damaged, contact Black Box Technical Support at 724-746-5500
or info@blackbox.com.

Chapter 3: Installation
3. Installation
Before installation, power off all devices that will be connected to this system.
Make sure that all devices you will connect are properly grounded.
Place cables away from fluorescent lights, air conditioners, and machines that are
likely to generate electrical noise.
NOTE: If no screen displays, follow these steps:
1. Make sure the device cables are correctly and firmly attached.
2. Set your display device’s input source as VGA.
3. Check the PC BIOS configuration for the video output settings.
4. Connect your computer to the display DIRECTLY to check if the video signal
gets through.

2 Video output Connects to the display.
3 Video source (input) Connects to the video source.
4 Serial connector Plug the serial cable in here.
3.2 Installation Steps
1. Use a video cable (VGA) to connect the display to the video output port on the
back of the switch. Plug a set of audio jacks from the speaker to the switch’s
speaker port.
2. Use a video cable (VGA) to connect the source device to the video input port
on the switch. Use an audio cable to connect the speaker port from the input
side of the unit to the corresponding output port on the source device.
3. Plug the power supply into the switch and power on the switch.
4. Turn on the display (monitor, projector, or TV) and then power on the source
device(s).
NOTE: For both AVSW-VGA4X1A and AVSW-VGA8X1A, each video source is
powered on, make sure it has a display pointing to it for EDID
communication. If a source does not have a display pointing to it, a video
image might not display.
