Control Tab

Selection of Video Input Source
Select a video input source from either USB-C or Video (HDMI port).
USB-C: Select the video input source as USB-C.
Video (HDMI port): Select the video input source as Video.
Auto: In this mode, it will automatically switch to the new connection source or the one that is just been powered on. When the currently active source loses power or is disconnected, it will seamlessly switch to another input source with active signal.
Also, when the transmitter restarts, it will remember the last connected video input source automatically.

Audio De-embedding Switch
Enable/disable the output of the 5-pin terminal block.
ON: Enable audio output from the 5-pin terminal block.
OFF: Disable audio output from the 5-pin terminal block.

Configuration Tab

EDID Settings
Choose the desired EDID format or define the appropriate EDID format.

• Pass Through: Tx Retrieve the EDID of the screen connected to the VIDEO port on the TX, then provide it to the video source. This will ensure that the image on the screen connected to the RX is adjusted to match the screen connected to the TX.
• Pass Through: Rx Retrieve the EDID of the screen connected to the VIDEO OUT port on the RX, then provide it to the video source. This will ensure that the image on the screen connected to the TX is adjusted to match the screen connected to the RX.
• Built-in EDID: There are 7 built-in EDID values can be selected by this tab.
• User-defined EDID: There are four EDID values can be customized by the below steps:

1. Prepare the EDID file (.bin) on the control PC.
2. Select the user-defined.
3. Click the black box, and then select the EDID file (.bin) according the tooltip.
4. Click Apply to upload the user-defined EDID.

HDCP Settings

Select an HDCP mode.

Auto Downscale
Enable: When the resolution of the display is lower than video input source, the resolution will automatically be downscaled to 1080p.
This feature enables the screen to at least show a relative low-resolution image instead of a blank screen.
Disable: Disable auto downscale feature.

Display

The page help to render the display connects to the Rx to turn on/off when the Tx is turned on/off.

Devices Power
Follow Host: Whether or not the devices connected to the DEVICES ports would get power depends on the ON/OFF state of the device connected to the HOST port. For example, when a camera connects to DEVICES ports, and a PC connects to HOST port. When the PC is turned on, the camera would automatically be turned on. When the PC is turned off, no power would be provided to the camera.
Always On: There will always power be provided to the devices connected to the DEVICES ports, even though the device connected to HOST port is powered off.

RS232 Control

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.
Click “OK” to close this 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 “)
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.
Select the right COM port.

In order to being 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)

[xx]=U1-U4 means custom built-in EDID (can be saved in the machine and recalled at any time), only one built-in EDID can be customized, and the current EDID still used after the customization is completed will not switch to the customized EDID.
After receiving the instruction, the machine will prompt to send the EDID file. The file format must be .bin within 10s (in order to ensure normal data reception, all Input XX/User Define EDID Upgrade OK!)
