Chapter 2: Overview
2. Overview
2.1 Introduction
The Presentation Switcher - HDBaseT, 4 x 1 is an advanced four-input, multi-format
converter, switcher, scaler, and extender with built-in 4K scaling, in a compact 1U
half-rack enclosure. It offers two HDMI inputs, one DP input, one VGA input with stereo audio, an HDMI with HDBaseT mirrored output to allow signal extension over CATx
cable to reach a remote display, or an additional HDBaseT signal management system.
One balanced stereo audio breaks out from HDMI output.
NOTE: Scaling is only supported on HDMI output. For scaling on HDBaseT output,
please use with VX-1003-TX scaling receiver.
The Switcher supports auto switching and has a built-in 4K @ 30 Hz scaler in HDMI
output, with rotary switch scaler adjustment, and allows seamless switching to enhance
presentations. Its built-in CEC controller automatically turns the display on/standby by
auto-detecting the input signal status. You can also control the Switcher via pushbuttons on the front panel, contact closures, and RS-232 API.
The Switcher simplifies classroom and small office system integration, for installation
beneath conference tables and in lecterns, to provide localized presentation switching
support.
2.2 Features
• Has (1) VGA + Stereo, (1) DP, and (2) HDMI inputs, and (1) HDMI and (1) HDBaseT
mirrored outputs.
• Supports HDMI and DP input up to 4K @ 30 Hz and HDCP 1.4, and VGA input up to
1920 x 120 0 @ 60 Hz.
• Provides HDMI out with a 4K @ 30 Hz scaler built-in and de-embedded balanced
stereo audio out.
• Mirrors out HDBaseT, and supports PoH with PSE module to power the remote
HDBaseT receiver.
• HDMI out supports seamless and fast switching within 2–3 seconds, and the last
frame is frozen.
• Switches automatically to the latest input when it detects that any input is connected
or disconnected.

Chapter 3: RS-232 Connection
3.2 Auto Mode
Auto Mode 1 (priority mode): VGA->DP->HDMI1->HDMI2
1. When you power on the switcher, it defaults to the VGA channel if no source is
active or connected. If some sources are already connected and then you power on
the switcher, it will detect their priority and auto switch to the active source with the
highest priority.
2. When you connect a new source after power on, the switcher might automatically
switch, depending on the priority. It will auto-switch to the new source if that source
has higher priority than currently selected source, otherwise, it will not auto-switch.
3. When the currently selected source is removed, the switcher might auto-switch,
depending on the status of other sources connected and their priority. It will auto
switch to the source active with highest priority, or remain on the current input
channel if no source is active.
4. Manual switching is also valid in Priority Mode. Press the button on the front panel to
switch among active sources. You can manually switch via contact closures or API
commands, depending on the source status. The unit will switch if the source manually selected is active, otherwise , an LED indicator will flash twice to indicate that a
source is not active and does not switch the source.
Auto Mode 2 (Last Connected):
1. When you power on the switcher, the VGA channel remains the default if no source
is active or connected. If some sources are already connected and then you power on
the switcher, it will detect their priority and auto switch to the active source with the
highest priority.
2. When you connect a new source after power on, the switcher will detect and autoswitch to this source.
3. When you remove a currently selected source, the switcher might automatically
connect to a source, depending on the status of other sources connected and
their priority. It will auto switch to the source active with highest priority, or remain
connected to the current input channel if no source is active.
4. Manual switching is also valid in Priority Mode. Press the front-panel button on the
front panel to switch among active sources. You can manually switch between
sources via contact closures or API commands depending on the source status. It will
switch if the source manually selected is active, otherwise, the LED indicator will
flassh twice to indicate the source is not active and does not switch.
