Introduction
Overview
SCA31TGB is an advanced switching extender set featuring four inputs and
UHD scaler. The included transmitter offers two HDMI inputs and one VGA
input with stereo audio, and the receiver offers an HDMI input, enabling an
additional AV source to be connected at the display location. The transmitter
supports HDBT output up to 230ft/70m at 1080P and up to 131ft /40m at
4K@60Hz (YUV 4:2:0) over a CATX cable. The receiver supports the stereo
audio de-embedding output from the HDMI output and connection with the
audio system, such as an amplifier. Built-in scaler with resolutions up to
4K@60Hz YUV 4:4:4 ensures the optimal image quality for video signal output,
and matches the native resolution of the display.
This extender set allows automatic and manual button switch among all inputs.
It features CEC controller to automatically turn on/off the display by
auto-detecting signal input. It also supports RS232 control to power on/off the
display such as projector, and relay control to turn on/off projection screen via
API commands. Its one way PoH enables the transmitter to receive power from
the power-on receiver; only one power supply is needed.
SCA31TGB simplifies system integration in classrooms and small offices, and
facilitates installation under conference tables and in lecterns, providing
localized presentation switching support over long distances.

Connections and Installations
1. Connect the VGA (such as PC) and HDMI sources (such as Blu-ray player,
Apple TV, 4K media player, etc) to the VGA IN, AUDIO IN and HDMI IN
ports of the transmitter respectively.
2. Connect the HDBT OUT of the transmitter to the HDBT IN of the receiver
via a qualified CAT5e/6/6a/7 cable.
3. Connect an HDMI source (such as BYOD system) to the HDMI IN port of
the receiver.
4. Connect the HDMI display device (such as projector) to the HDMI OUT of
the receiver.
5. Connect an audio receiver to the AUDIO OUT of the receiver.
6. Connect the projection screen to the RELAY1 and RELAY2 of the receiver
to control the screen.
7. Connect a PC to the LAN port of the receiver for Telnet control.
8. Connect the included DC 12V power supply to the receiver. One-way PoH
enables the power to be sent from receiver to transmitter along a single
CATX cable, and no additional power adapter is required at the
transmitter.

Input Source Switch
This extender set supports auto and manual button switch between the
HDBT and HDMI inputs.
Auto Switch
Press AUTO button, auto switch function will be activated immediately.
Priority: HDMI 1 > HDMI 2 > VGA (for transmitter); HDBT > HDMI (for
receiver).
1. When multiple sources are inserted, power on all devices, the input in
top priority will be selected.
2. When a source is removed, the input will be switched to the source in
top priority automatically.
3. When a new source is inserted, the input will be switched to the new
source automatically.
Note: The auto switch function will be activated by default once all devices
are powered on.
Manual Button Switch
Users can manually switch to specific inputs among the multiple sources by
pressing the corresponding buttons on the rear panel of both units (see
buttons in red frames above). When the manual switch function is triggered,
the auto switch function will be inactivated simultaneously.

API Command Control
SCA31TGB support API command control via RS232, FW UPDATE and LAN
ports.
Example:
To power on/off the connected display like projector in real time via API
commands, here list the following steps for users’ reference.
1. Connection
Control at transmitter
Connect a PC to the RS232/FW UPDATE port of the transmitter, and
connect a projector to the RS232 port of any other HDBT receiver.

2. Set serial port parameters
Suppose the RS232 control codes for your connected projector are as
follows,
Baudrate: 9600
Power on: 50 57 52 20 4F 4E 0D 0A
Power off: 50 57 52 20 4F 46 46 0D 0A
First, open your serial debugging tool in the PC, set the UART baudrate
to 9600.
Control at transmitter: enter command “SET UART_INFO 9600 tx”
and end it up with CR/LF, click “Send”.
