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
PT-PSW-52can be controlled via web-based GUI.
Step9. Connect control device (e.g. PC) to the RS232 port of the PT-PSW-52or the
HDBaseT Receiver (bi-directional RS232 control, either end is available).
Step10. Connect IR receiver to the IR EYE port, the PT-PSW-52can be control via IR
remote. For more details, please refer to 4.2.IR Control.
Step11. Both the PT-PSW-52and 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 PT-PSW-52connects 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 PT-PSW-52and
the HDBaseT Receiver.
Step12. Connect DC24V power adaptor to the power port (HDBaseT Receiver can
be powered by the PT-PSW-52with PoH function).
Note: If the power adapter is connecting with HDBaseT Receiver, the PT-PSW-52can’t be
powered from HDBaseT Receiver.

3.4 Microphone Connection
The PT-PSW-52 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.

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.

4. System Operation
4.1 Button Control
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 PT-PSW-52have 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.

User Manual
PT-PSW-52

Signal removing
Once removing the current display signal, the PT-PSW-52will 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 Adjustment
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.
