3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. BluRay / DVD) to 1~3 HDMI
input ports with HDMI cable
Step2. Connect a DisplayPort source device (e.g. MAC MINI) to DP input
port with DisplayPort cable and DP audio input port with audio cable.
Step3. Connect a VGA source device (e.g. Laptop) to VGA input port with VGA
cable and VGA audio input port with audio cable.
Step4. Select MIC level and connect right microphone to MIC input port. MIC
audio will be transmitted to AUDIO OUTPUT port and mixed with source
audio.
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 amplier 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) to the RS232 port of the Scaler Switcher
or the HDBaseT Receiver (bi-directional RS232 control, either end is
available).
Step10. Connect IR receiver to the IR EYE port, the Scaler Switcher can be control
via IR remote. For more details, please refer to 4.2.IR Control.
Step11. Both the Scaler Switcher and the HDBaseT Receiver have IR IN and OUT.
When one model is connected with IR receiver, the other model should
connect with an IR transmitter.
For example: When “IR IN” of the Scaler Switcher connects with an IR
receiver, the IR transmitter must connect to IR OUT of HDBaseT Receiver.
The IR signal can be transmitted bi-directionally between the Scaler
Switcher and the HDBaseT Receiver.
Step12. Connect DC24V power adaptor to the power port (HDBaseT Receiver can
be powered by the Scaler Switcher with PoH function).
Note: If the power adapter is connected to an HDBaseT Receiver, the Scaler Switcher
can’t be powered from HDBaseT Receiver.

impedance and high sensitivity.
When switching to “48V”, the MIC input will provide a 48V phantom power. This
is only used for condenser microphones.
Connect the microphone in this way: “+” connects to positive, “-” connects to
negative and “ ” to ground.

Front panel buttons can be used for switching operations and volume adjusting.
4.1.1 Manual-Switching
Press 1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA on front panel to select the
corresponding input source.
4.1.2 Auto-Switching
Press AUTO to enter in auto-switching mode.
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 conguration 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 with priority from 1-HDMI/MHL to 5-VGA.
When the rst signal is detected, it will transfer to the output.
» Signal removing
Once removing the current display signal, the Scaler Switcher will detect all
input signals with priority from 1-HDMI/MHL to 5-VGA. It will then transfer the
rst detected available signal to the output devices.
