Product Introduction

The PT-MA-HDBT42 is a four-input by two-output matrix switcher with two HDBaseT inputs, two HDMI inputs and two HDBaseT + HDMI outputs. The switcher transmits 4K video to distances up to 131 feet (40 meters) and 1080p video to distances up to 230 feet (70 meters) over a single CATx cable. The HDBaseT inputs and outputs support 48V Power over Cable (PoC) feature, allowing the compatible transmitters and receivers to draw their power from the matrix over the CATx cable.
The matrix supports downscaling so a 4K video input can automatically be downscaled to a 1080p output when connecting a display that only supports resolution up to 1080p. Moreover, the matrix switcher features comprehensive EDID management and advanced HDCP handing to ensure maximum functionality with a wide range of video sources. The switcher offers IR, RS232 and TCP/IP control options.

Features

• 4x2 matrix switcher with HDBaseT inputs and outputs.
• Fully compliant with the HDMI V2.0 and HDCP 2.2.
• Supports video resolution up to 4K@60Hz 4:4:4, HDR10, Dolby Vision.
• Supports auto-switching.
• Features two mirrored HDMI outputs for two HDBaseT outputs, and all outputs support 4K to 1080p down-scaling.
• HDBaseT inputs and outputs support 48V PoC, allowing the transmitters and receivers to draw their power from the matrix switcher over CATx cables.
• Visually lossless video de-compression and compression for HDMI signals transmission up to 40m at 4K and 70m at 1080p on HDBaseT inputs and outputs.
• Supports Stereo + SPDIF audio outputs for audio de-embedding.
• Controllable via front panel buttons, RS232, IR and TCP/IP (built-in GUI).

RS232 Control Software

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 “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.
Click “Continue” to close this 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.

Click “Play” to open the communication.
Enable the keyboard type in function.

Firmware Upgrade

Please follow the steps below to upgrade the firmware by the FW port on the front panel:

1. Prepare the latest upgrade file (.bin) and rename it as “FW_MERG.bin”.
2. Connect the switcher to the PC with USB to Micro USB cable, and then power on the switcher. The PC will automatically detect a U-disk named of “BOOTDISK”.
3. Double-click the U-disk, a file named of “READY.TXT” would be shown.
4. Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
5. Reopen the U-disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirmed again, and then follow the above steps to update again.
6. Remove the USB to Micro USB cable after firmware upgrade, and reboot the switcher.
