3. System Connection
3.1 Usage Precautions
1) System should be installed in a clean environment, which should have a proper
temperature and humidity.
2) All of the power switches, plugs, sockets and power cords should be insulated and
safe.
3) All devices should be connected before powered on.
4) System Diagram shown in this manual is for reference only; more specific schemes
depend on real-time applications.

3.3 Connection Procedure
Step1.Connect HDMI source devices (e.g. Blue-ray 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 amplifier to AUDIO OUTPUT port.
Step8.Connect control device (e.g. PC, control system) 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 connecting with the HDBaseT Receiver, the Scaler
Switcher can’t be powered from HDBaseT Receiver.

3.4 Connection of Microphone
The Scaler Switcher provides with one 3-level microphone input port, to accommodate
different microphone input modes, including 48V phantom power mode, MIC mode &
LINE mode.
➢48V phantom power Mode
48V phantom power input has a good frequency characteristic, high input impedance
and high sensitivity.
When switching to “48V”, the MIC input will provide a 48V phantom power. This is only
used for condenser microphone.
Connect the microphone in this way: “+” connects to positive, “-” connects to negative
and “ ” to ground.
➢MIC Mode
MIC input has a low frequency characteristics, and wide frequency response.
When switch to “MIC”, the microphone input is used for connecting with dynamic
microphone. There are two different connection methods:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.

KANEXPRO SW-HDSC51HDBT
14 | P a g e
2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”
connects to ground.
➢LINE Mode
LINE input has a low frequency characteristics, and wide frequency response.
When switch to “LINE”, the microphone input is used for connecting with line audio or
wireless microphone output. There are two different connection methods:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”
connects to ground.

3.5 System Application
The Scaler Switcher has an ideal use in lecture halls, boardrooms and conference
room set-ups where DisplayPort and HDMI based laptops and other devices can be
used for fast switching & scaling with legacy video formats such as VGA to one or more
displays over HDBaseT up to 70 meters.

4. System Operations
4.1 Front Panel Buttons
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 can 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 5-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 5-VGA. It will transfer the signal firstly
detected to be available to output devices.
Note:
When the DP signal is switched as input, the DP source device may not read the
EDID data from display device, at this point re-plug the DP source device to solve
this phenomenon.
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.
