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.
Switch to "48V" | Condenser Microphone
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:
- Unbalanced connection: “+” and “⏚” connect to ground, and “-” connects to signal. “-” and “⏚” connect to ground, and “+” connects to signal.
Dynamic Microphone connection diagrams
- 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:

- Unbalanced connection: “+” and “ ” connect to ground, and “–” connects to signal.

- “–” and “ ” connect to ground, and “+” connects to signal.

Application
The PT-PSW-52 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.

Button Control
Front panel buttons can be used for switching operations and volume adjusting.
Manual Switching
Press 1-HDMI/MHL, 2-HDMI, 3-HDMI, 4-DP, 5-VGA on front panel to select the corresponding input source.
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-52 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, the PT-PSW-52 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.
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.
IR Control
IR Remote
Connect IR receiver to IR EYE port, the PT-PSW-52cans be controlled by using IR remote. As CEC function, it is able to use the IR remote to turn on/off the HDMI source or Display.

CEC Function
The PT-PSW-52 supports CEC, it can be turned on/ off by sending RS232 commands or OSD menu operations. The default setting is ON.
Commands pertaining to CEC: 50686% (enable CEC) and 50687% (disable CEC)

HDMI INPUT ports 1~3 support CEC, if the connected source devices also support CEC and their CEC are on, users can control the source device and display via the IR remote of the PT-PSW-52.

| Situation | Working Status |
|---|---|
| CEC: on, Standby: on | Press STANDBY button on IR remote, the PT-PSW-52 enters in standby mode, so do all HDMI source devices and display. Press STANDBY button again on IR remote, the PT-PSW-52 exits standby mode, the previous selected HDMI input source device and display start working too. |
| CEC: on, Standby: off | Press STANDBY button on IR remote, the PT-PSW-52 enters in standby mode, HDMI 1~3 source devices and display keep on. |
| CEC: on | Use [▲] [▼] [◀] [▶] and [OK] buttons on IR remote to control HDMI source device. |
| CEC: off | Unable to control HDMI source device and display through IR remote |
IR Receiver and connections for HDMI input sources (DVD) and output (HDTV)
RS232 Control
As RS232 can be transmitted bi-directionally between the PT-PSW-52 and the HDBaseT Receiver, so it is able to control a third party RS232 device from local or control the PT-PSW-52 from remote. The baud rate support 2400, 4800, 9600 (default), 19200, 38400, 57600 or 115200.
RS232 Control Software
Here take the software docklight as an example.
- Installation Please download the latest Software Version from the link below: https://docklight.de/download/Docklight.zip Then follow the installation wizard for installation on Windows 7 and 10. After the installation, Docklight can be run for the first time and should look like the below screen shot: Registration is not necessary unless you wish to save settings on exit, so unless you wish to register click on "OK" to close the window.

Click "OK" to close this
The next pop-up window can also be closed with "Continue". An empty project is enough to send and receive commands easily (The default setting is always "Start with a blank project / blank script")

Click "Continue" to close this window.
Now you are in the main view, where commands are sent and feedback is received.
The next step is to select the correct COM port of the PC. To do this, double-click on "COM1" in the corresponding setup window.

Double click on "COM1" to change to the right COM port.
In the following window, select the drop-down menu labeled "Send / Receive on Comm Channel", select the appropriate COM port and then click on "OK" at the bottom right corner.
All other settings can be left at default for most applications, but refer to device RS232 settings to be sure.
Select the right COM port.
- In order to be able to send commands, open communication with the device by clicking on "Play".
- Then the keyboard function must be activated, so that commands can be written in the "communication window".
