The end connecting to the VS482 should have a 9-pin male connector. Connect this to the serial interface on the rear of the VS482. Refer to number 5 on the previous diagram.

Note:

To configure the controller serial port, see page 15.

Chapter 3 Operation

Overview

The 4-Port Dual View HDMI Switch offers easy and flexible source device selection with either the front panel pushbuttons, remote control, or through the

RS-232 serial interface, and system settings via OSD menu.

Note: 1. Whenever the VS482 is powered on and there is no video input source connected, it automatically selects Port 1 as the active port (i.e., the

Port 1 LED lights up). You may choose one of the methods outlined below to select a different port as your active port.

2. The VS482 takes about 10-20 seconds to boot up and apply system configuration settings when first powered on.

Manual Port Selection

To select an HDMI source device, press the pushbutton on the front panel that corresponds to the port to which the device is connected.

Note: The Port LED (green) light indicates which port is currently selected.

Remote Control Selection

To select a source device with the remote control, press the number button that corresponds to the port which the HDMI device is connected.

See IR Remote Control , page 6 for more details.

Note: Aim the remote control at the IR receiver located on the front panel of the VS482. For optimum performance, make sure there is a clear lineof-sight between the remote control unit and the IR receiver.

VS482 User Manual

Switch Mode

You can choose how the VS482 behaves when a new input source is connected.

The switch modes can be set via RS-232 commands (see Switch Mode

Commands , page 18) by connecting a computer or hardware controller to the

VS482’s RS-232 port. If you are using a computer you can download the RS-

232 AP GUI from our website to configure these additional settings. There are three Switch Modes as follows:

 Default – The switch behaves normally without automatic switching operation.

 Next – Switch priority is placed on the next port that has a new source connected to it (default).

 Auto – Places priority on a selected port so that when a source is connected to the said port, the VS482 automatically switches to it, and the port can not be changed until the source is unplugged or auto switching is disabled.

In addition, the Go To function, which can be turned On or Off via RS-232 commands, enables the VS482 to switch to the next port with a powered on source device when the current input source is off. Refer to

Switch Mode

Commands , page 18 for more details.

Chapter 3. Operation

Audio Return Channel (ARC)

Audio Return Channel (ARC) allows an HDMI source device that receives content via air waves (such as a TV or STB connected to a satellite antenna) to send audio “upstream” to your HDMI display devices using only one HDMI cable.

Initial Setup

The VS482 supports dual HDMI outputs for HDTVs and/or audio/video receiver (AVR) applications, as shown in the following diagram.

HDMI Sources or

Audio Output or

HDMI Displays

The audio/video coming from the HDMI sources (Blu-ray, DVD, etc.) are received by the VS482 and then passed on to the HDMI displays (TV, projector or AVR).

However if the HDMI audio or video is coming from the TV (through a satellite antenna or STB), you can enable ARC so that audio is sent to the AVR/

HDMI receiver through the HDMI cable or the device(s) connected to the

audio output port(s). See p. 14 for the diagram.

Note: 1. Without ARC, you must connect another cable, specifically for passing audio, from the TV to the AVR or the device(s) connected to the audio output port(s).

2. The ARC function requires an HDTV built-in ARC function and must be connected to the correct HDMI output port. Check your HDTV’s user manual for this information.

VS482 User Manual

Enabling ARC

With ARC enabled, the TV can act as the HDMI source and send audio

“upstream” to the AVR or speakers connected to the HDMI output ports of the

VS482.

Note: The HDMI output port 1 is also the ARC input port, depending on

whether the ARC feature is enabled or disabled. See ARC Commands , page 23 for more information.

In the following diagram, audio from the TV goes to the VS482 through the

ARC Input port, and is then passed on to the AVR via the HDMI cable or the audio devices connected to the HDMI output ports. A user can also connect to an audio device (receiver) using an optical or coaxial audio connector.
