Chapter 3
Operation
Overview
The 4-Port True 4K HDMI Switch with Dual Output 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 VS482B 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 VS482B 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 VS482B. For optimum performance, make sure there is a clear line-
of-sight between the remote control unit and the IR receiver.

Switch Mode
You can choose how the VS482B behaves when a new input source is
connected. The switch modes can be set via RS-232 commands (see Switch
Mode Commands, page 19) 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 VS482B 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 VS482B 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 19 for more details.

receiver (AVR) applications, as shown in the following diagram.
The audio/video coming from the HDMI sources (Blu-ray, DVD, etc.) are
received by the VS482B 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.

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
VS482B.
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 24 for more information.
In the following diagram, audio from the TV goes to the VS482B 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.
Note: 1. The scenario above works only if the TV supports HDMI and has
ARC enabled.
2. The ARC LED (blue) lights up to indicate that the ARC function is
enabled. There is no audio output if your HDTV does not support
ARC function or if the ARC function is not enabled.
