CHAPTER 1: HEADLINE
CHAPTER 2: OVERVIEW
2.1 INTRODUCTION
The 8 x 2 Video Matrix Switcher, 18G Seamless Switching, HDMI 2.0 4K 60 Hz 4:4:4 HDR simplifies meeting room and presentation space
system integration by providing one HDBaseT input, four HDMI inputs, one VGA input, one DP input, one USB-C input, one HDBaseT
output and one HDMI output. It also provides external audio inputs to be embedded in HDBaseT, HDMI and VGA video inputs respectively.
Moreover, it provides MIX audio input for global audio.
The matrix switcher provides true 4K scaling up to 4K @ 60 Hz @ 4:4:4. Both inputs and outputs are capable of providing 4K @ 60 Hz
@ 4:4:4 signals. The HDBaseT input and output provide an innovative solution with VLC technology, allowing transmission of HDMI 2.0
signals over a CATx cable while ensuring very high, original image quality. It is designed for use with the VX-HDB2-KIT extender kit. The
USB-C input is ideal for AV interfacing with newer MacBook, Chromebook, and Windows PC, as well as smart phones and tablets.
The matrix switcher supports auto switching on HDMI, HDBaseT and HDMI loop outputs based on TMDS activity signals sensing. It also
allows users to control system functionality via Web GUI, RS-232, IR and CEC. Additionally, users can control a relay device such as the
rise and fall of a projector screen over RELAY ports.
The matrix switcher is designed to be the central component of AV system. It is ideal for applications where multiple signals with
different resolutions must be optimized for displays. It is also suitable for presentation spaces where two displays are needed.

7.3.10 THIRD-PARTY DEVICE CONTROL
The switcher supports RS-232 pass-through control. A third-party device can be controlled by an RS-232 command, and the command
format is shown next.
TABLE 7-12. THIRD-PARTY DEVICE CONTROL
COMMAND FUNCTION COMMAND EXAMPLE
RS-232 mode selection:
• Y=0, Local Control: The RS-232 port of the switcher is used to connect a control
device (e.g. PC) to control the switcher.
• Y=1, HDBT Transmitter Pass Through: Establish RS-232 pass-through
UARTPassThrough:Y.
/+[X]/[Y]:xxx.
communication between the switcher and the HDBaseT transmitter (e.g. VXHDB2-TX). The RS-232 port of the switcher can be used to transfer commands to
control the third-party device that is connected to the HDBaseT transmitter.
• Y=2, HDBT Receiver Pass-through: Establish RS-232 pass-through communication
between the switcher and HDBaseT receiver (e.g. VX-HDB2-RX). The RS-232 port
of the switcher can be used to transfer commands to control the third-party device
that is connected to the HDBaseT receiver.
xxx: ASCII characters.
• Y: Represents the RS-232 port.
1. Y=1: The RS-232 port of switcher.
2. Y=2: The RS-232 port of HDBaseT receiver.
3. Y=3: The RS-232 port of HDBaseT transmitter.
• X: Represents the baud rate of the third-party device.
1. X=1, 2400
2. X=2, 4800
3. X=3, 9600
4. X=4, 19200
5. X=5, 38400
6. X=6, 57600
7. X=7, 115200
Send the command
“123456” to the third-party
device. The baud rate is
9600.
