Step8. Connect a reset button to the SIG 5V port as needed, the button can be used as
a video source selector.
Step9. Connect the included IR Receiver to the IR IN port, the Switcher can be
controlled through the IR remote. While connect an IR Emitter to the IR OUT
port of HDBaseT port, the third party device connected to HDBaseT Receiver
also can be controlled via IR remote.
Step10. Connect control device (e.g. PC) to the RS232 port of the Scaler Switcher or
HDBaseT Receiver (bi-directional RS232 control, either end is available). The
Scaler Switcher can be control by sending RS232 commands via PC.
Step11. Connect DC12V power adaptor to the power port (HDBaseT Receiver is able
to get power from the Scaler Switcher with PoH function).
Notice: The Scaler Switcher supports unidirectional PoH, i.e., If the power adapter is
connecting with the Switcher, HDBaseT Receiver can be powered through HDBT port; but
when the power adapter is connecting with HDBaseT Receiver, the Switcher cannot be
powered by the HDBaseT Receiver.
3.4 Application
The Scaler Switcher has a good application in various occasions, such as computer
realm, monitoring, conference room, big screen displaying, television education,
command & control center and smart home etc.

4. System Operation
4.1 Button Control
Front panel buttons can be used for source selections, there are 4 sources for choose
in total, including HDMI, DP, DVI, VGA. Video signals support auto-switching and
manual switching (factory default).
4.1.1 Manual Switching
Press to SOURCE/AUTO button select one source, press again to select next source,
switching sequentially between HDMI, DP, DVI and VGA.
4.1.2 Auto Switching
Press and hold for SOURCE/AUTO button for 3 seconds or more to enter in
auto-switching mode. In this mode, the Scaler Switcher will follow these rules to
select input source automatically.
New input:
Once detecting a new input signal, the Scaler Switcher would switch to this new
signal automatically.
Rebooting device
The Scaler Switcher have the ability to save the last configuration before losing
power. If the last switching mode is auto-switching, once rebooted, the Scaler
Switcher will automatically enter auto-switching mode, and then detect all inputs
and memorize their connection status for future rebooting using. If the last
displayed signal is still available, the unit will output the signal. If not, the unit will
detect all the inputs signals with priority from HDMI to VGA. When detected the
first signal, it will transfer to output.

Signal removing
Once removing the current display signal, the Scaler Switcher will detect all input
signals with priority from HDMI to VGA. When detected the first signal, it will
transfer to output.
Notice:
In manual-switching mode, if you set the signal format of VGA/DVI input to
C-video or YPbPr, the system will not be able to enter Auto-switching mode.
In auto-switching mode, if the signal format of DVI input is C-video/YPbPr, the
Scaler Switcher can’t detect the DVI input, the command 50686% should be sent
via PC to convert C-video/YPbPr into digital signal format, and then the Scaler
Switcher will enter
In auto-switching mode, select input source via front panel button is not
available, but RS232 command and IR remote are able to switch mode.
4.2 IR Control
4.2.1 Control the Scaler Switcher
Firstly, connect IR Receiver to IR IN port;
