4x2 HDMI 2.0 Seamless Matrix Switcher
1. Product Introduction
Thanks for choosing the SCU42TS 4x2 multi-format seamless presentation
matrix switcher with one TPUH610SR receiver! The matrix switcher simplifies
meeting room and presentation space system integration by providing three
HDMI inputs, one USB-C input, one HDMI output and one HDBaseT output
with one HDMI loop output. It also provides external one audio input to be
embedded in the first HDMI input. Moreover, it provides one MIX audio input
and one MIC audio input for global audio.
The matrix switcher provides true 4K scaling up to 4K@60Hz@4:4:4. Both
inputs and outputs are capable of providing 4K@60Hz@4:4:4 signals. The
HDBaseT output provides an innovative solution 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 TPUH610SR receiver. 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 with HDMI
loop outputs based on TMDS activity signals sensing. It also allows users to
control system functionality via Web GUI, RS232, IR and CEC.
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.

4.3 RS232 Connection
The switcher supports RS232 local control and RS232 pass-through, and the
receiver supports RS232 pass-through. There are five modes of RS232 control
connection as described below:
1. Connect a PC to the switcher’s RS232 port to control the switcher by
sending RS232 commands. Please refer to chapter 8. RS232 Control for
more details.
2. Connect a PC to the receiver’s RS232 port to control the switcher by
sending RS232 commands.
3. Connect a PC to the switcher’s RS232 port to control, via RS232
commands, a far-end third-party device (e.g., projector) which is
connected to the receiver’s RS232 port.
4. Connect a PC to the receiver’s RS232 port to control, via RS232
16
4x2 HDMI 2.0 Seamless Matrix Switcher
commands, a local third-party device which is connected to the
switcher’s RS232 port.
5. Connect a third-party device to the switcher’s RS232. The third-party
device can be controlled by sending RS232 commands via the GUI’s
RS232 Control tab. Refer to section 7.7 RS232 Control Tab for more
details.
4.4 IR Connection
The switcher provides an IR EYE port for switcher control and provides IR
IN and IR OUT ports to be used together with the receiver’s IR In and IR Out
ports for source or display device control.
1. Connect the IR receiver to the switcher’s IR EYE port to control the
switcher via the IR remote.
2. Control the far-end display device: Connect the IR receiver to the
switcher’s IR IN port, then connect the IR emitter to the receiver’s IR Out
port. A display device that is connected to the receiver can be controlled
from the local switcher by its IR remote.
3. Control the local source device: Connect the IR receiver to the receiver’s
IR In port, then connect the IR emitter to the switcher’s IR OUT port. A
source device that is connected to the switcher can be controlled from
the far-end receiver by its IR remote.
5. Button Control
5.1 Manual Switching
When the switcher is in manual switching mode, the AUTO button’s LED
turns off. Follow these steps to select the output channel’s input source.
1. Press any one of the four input buttons to select the input source. The
corresponding button’s LED turns blue.
2. Press either the 1.HDMI or 2.HDBT output button to select an output
channel. The corresponding button’s LED turns blue.
3. Press the input button again to confirm the selected setting; otherwise, it
will automatically confirm after three seconds.
5.2 Auto Switching
Follow these steps to enable auto switching mode for 1.HDMI or 2.HDBT
output.
1. Press AUTO. The button’s LED will turn blue.
2. Press either the 1.HDMI or 2.HDBT output button. The corresponding
button’s LED will turn blue.
3. Press the AUTO button again to confirm the selected setting; otherwise,
17
4x2 HDMI 2.0 Seamless Matrix Switcher
it will automatically confirm after three seconds.
4. Repeat the preceding three steps to exit auto mode. The input source will
remain the current setting.
Note: The AUTO button LED illuminates blue when the 1.HDMI output is in
auto mode or the 2.HDBT output in auto mode.
When in auto mode, the switcher will switch according to the following rules:
• The switcher will switch to the first available active input starting at
input 1.
• New input: The switcher will automatically select the new input after
it detects a new input.
• Reboot: If power is restored to the switcher, it will automatically
reconnect to the input that was selected before the switcher was
powered off.
• Source removed: When an active source is removed, the switcher will
switch to the first available active input starting at the 1.HDMI input.
• In auto mode, the input source also can be switched by following the
manual switching steps.
5.3 Switching Status Query
• Press any input button to determine its corresponding output channel.
• Press any output button to determine its corresponding input channel.
Example: The 2.HDMI input is switched to HDMI OUT.
Press the 2.HDMI input button. The 2.HDMI source button and the 1.HDMI
output button will illuminate blue for 3 seconds.
Press the 1.HDMI output button. The 2.HDMI source button will illuminate blue
for 3 seconds.
