Chapter 2: Overview
2. Overview
2.1 Introduction
The 2- and 4-Port DisplayPort Switches enable users to quickly and easily share a
single DisplayPort display with a Blu-ray player, HD-DVD, Xbox®, Wii®, PS3, satellite
receiver, etc.) 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 meters) or push button on the switch. You don’t need to plug
and unplug video sources, making it more convenient, more affordable, and more
efficient to use your A/V equipment.
The built-in serial interface also enables users to control the Video Switch through
a PC, serial controller devices, or home theater system, integrating the whole A/V
environment (depends on model).

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 DisplayPort.
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.

5* Audio output Connects to the speaker.
6* Serial connector Plug the serial cable in here.
*Available for AVSW-DP2X1A and AVSW-DP4X1A models only.
3.2 Installation Steps
1. Use a Video Cable (DisplayPort) to connect the Display to the video output port
on the back of the switch. For models with the standard audio feature, plug a
set of audio jacks from the speaker to the Switch’s speaker port.
2. Use a Video Cable (DisplayPort) to connect the source device to the video input
port on the switch. For the models that support audio (AVSW-DP2X1A and
AVSW-DP4X1A), 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: When 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.
