Product Introduction
Thanks for choosing the PT-PMS-42S 4x2 multi-format seamless presentation matrix switcher with one PT-HDBT-210-RX receiver! The matrix switcher simplifies meeting room and presentation space system integration by providing three HDMI inputs, one USB-C input, one HDMI output and one HDBaseT output with one HDMI loop output. It also provides external one audio input to be embedded in the first HDMI input. Moreover, it provides one MIX audio input and one MIC audio input for global audio.
The matrix switcher provides true 4K scaling up to 4K@60Hz@4:4:4. Both inputs and outputs are capable of providing 4K@60Hz@4:4:4 signals. The HDBaseT output provides an innovative solution allowing transmission of HDMI 2.0 signals over a CATx cable while ensuring very high, original image quality. It is designed for use with the PT-HDBT-210-RX receiver. The USB-C input is ideal for AV interfacing with newer MacBook, Chromebook, and Windows PC, as well as smart phones and tablets.
The matrix switcher supports auto switching on HDMI, HDBaseT with HDMI loop outputs based on TMDS activity signals sensing. It also allows users to control system functionality via Web GUI, RS232, IR and CEC.
The matrix switcher is designed to be the central component of AV system. It is ideal for applications where multiple signals with different resolutions must be optimized for displays. It is also suitable for presentation spaces where two displays are needed.

Connect the RS232 port to control device (e.g. PC) with RS232 cable. The switcher can be controlled by sending RS232 commands.
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.

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.
Click “OK” 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.
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.
Double click on “COM1” to change to the right COM port.

In order to be able to send commands, open communication with the device by clicking on "Play". (1)
Then the keyboard function must be activated, so that commands can be written in the "communication window". (2)
Finally enter the command, for example "50701%". This is then confirmed by pressing "Enter" to send. Any response from the connected device will appear in red. (3)
Select the right COM port.

RS232 Command
Communication protocol: RS232 Communication Protocol
Baud rate: 9600 Data bit: 8 Stop bit: 1 Parity bit: none
Note: All commands needs to be ended with “<CR><LF>”.
In the commands, “[”and “]” are symbols for easy reading and do not need to be typed in actual operation.
Type the command carefully, it is case-sensitive.
Click “Play” to open the communication.
