Step4.Connect audio source device to the audio input port with audio cable.
Step5.Connect a HDMI display device to HDMI output port with HDMI cable.
Step6.Connect HDBaseT Receiver to HDBT output port with twisted pair.
Step7.Connect speaker, headphone or AV amplifier to AUDIO OUTPUT port.
Step8. Connect control device (e.g. PC) to the TCP/IP port, the Scaler Switcher can
be controlled via web-based GUI.
Step9. Connect control device (e.g. PC, control system) to the RS232 port of the
Scaler Switcher or HDBaseT Receiver (bi-directional RS232 control, either end is
available).
Step10. Connect IR Receiver to the IR EYE port, the Scaler Switcher can be
controlled via IR Remote. For more details, please refer to 5. IR Control.
Step11. Both the Scaler Switcher and HDBaseT Receiver have IR IN and OUT. When
one model is connected with IR Receiver, the other model should connect with an
IR Emitter.
For example: When “IR IN” of the Scaler Switcher connects with an IR Receiver,
the IR Emitter must connect to IR OUT of HDBaseT Receiver.

corresponding input source.
4.2 Auto-Switching
Press AUTO to enter in auto-switching mode, and the auto-switching mode abides by
the following principles:
New input
Once detecting a new input signal, the 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 switcher will
automatically enter auto-switching mode, 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 input signals
wit priority from 1-HDMI/MHL to 6-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 1-HDMI/MHL to 6-VGA. It will transfer the signal firstly
detected to be available to output devices.
Note: Auto-switching function works only when inputting new signal, removing a signal
or power rebooting. With any VGA port set to C-video or YPbPr, the system will be not
able to enter in Auto-switching mode.
4.3 Volume Adjusting
Press Volume knob to select MIX or Source audio to adjust, the corresponding LED will
turn green and keep on, and then move the volume knob in clockwise or anti-clockwise
direction to turn up/down sound volume.
