3. System Connection
3.1 Usage Precautions
System should be installed in a clean environment and has a prop temperature
and humidity.
All of the power switches, plugs, sockets and power cords should be insulated
and safe.
All devices should be connected before power on.
3.2 System Diagram
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.

Compact Scaler Switcher (with PoH)
GeMNeXT www.GeMNext.com
Step6.Connect HDBaseT Receiver (such as EXT-HBT70-R) 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, PS-5IN-SCALER can be
controlled via web-based GUI.
Step9.Connect control device (e.g. PC, control system) to the RS232 port of
PS-5IN-SCALER or HDBaseT Receiver (bi-directional RS232 control, either end
is available).
Step10. Connect IR receiver to the IR EYE port, PS-5IN-SCALER can be control via
IR remote. For more details, please refer to 4.2.IR Control.
Step11. Both PS-5IN-SCALER and 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 PS-5IN-SCALER 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 PS-5IN-SCALER
and HDBaseT Receiver.
Step12. Connect DC24V power adaptor to the power port (HDBaseT Receiver can
be powered by PS-5IN-SCALER with PoH function).
Note: If the power adapter is connecting with HDBaseT Receiver, PS-5IN-SCALER
can’t be powered from HDBaseT Receiver.
3.4 Connection of Microphone
PS-5IN-SCALER 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.

Compact Scaler Switcher (with PoH)
GeMNeXT www.GeMNext.com
➢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.
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.

Compact Scaler Switcher (with PoH)
GeMNeXT www.GeMNext.com
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 Application
PS-5IN-SCALER 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 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
PS-5IN-SCALER 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 5-VGA. When detected the first signal, it will
transfer to output.
➢Signal removing
Once removing the current display signal, PS-5IN-SCALER 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.
4.1.3 Volume Adjusting
Press Volume Knob to choose MIC/Source audio needed to be adjusted, the
corresponding LED will turn green and keep on.
Adjusting the Volume Knob in clockwise direction to increase sound volume.
Adjusting the Volume Knob in anti-clockwise direction to decrease sound volume.
