Button Control

Manual Switching

When the switcher is in the manual switching mode, press the SELECT button repeatedly to cycle through the two video inputs, and the corresponding source LED illuminates red immediately.

Automatic Switching

Press and hold the SELECT button for at least three seconds to enable automatic switching. When in the AUTO mode, the unit will switch according to the following rules:

  • New host: Once detecting a new host, the unit will automatically select the new host.
  • Pressing the SELECT button will forcibly change the host even in AUTO mode.
  • After reboot: Once power is restored to the unit, it will automatically reconnect the host that was active before the reboot.
  • Source removed: When an active host is removed, the switcher will switch to the other active host.
  • Press and hold the SELECT button for at least three seconds and the unit will exit AUTO mode and the host will not change.

Display Control

Manual Control: Press the below DISPLAY buttons on the front panel to simultaneously send RS232 and CEC commands to control the display device. ON: Display On. OFF: Display Off. : Mute/Unmute display audio.

EDID&HDCP Settings

The switch represents 0 when in the lower (OFF) position, and it represents 1 in the upper (ON) position.

EDID Settings

The Extended Display Identification Data (EDID) is used for the source device to match its video resolution with the connected display. By default, the source device obtains its EDID from the first connected display. Meanwhile, since the displays with different capabilities are connected to the switcher, pins1~3 of the DIP switch on the front panel can be used to set the EDID to a built-in fixed value.

HDCP Settings

High-bandwidth Digital Content Protection (HDCP) is a copy-protection scheme to eliminate the possibility of capturing digital content from the source to the display. Pin4 of the DIP switch on the front panel can be used to set HDCP.

Switch StatusDescription
1HDCP follow display.
0 (Default)If the source has HDCP, the output will be set to HDCP 1.4; If the source has no HDCP, the output will be set to no HDCP.

RS232 Control

Connect an RS232 cable to a control device (e.g. PC) with an RS232 cable. The switcher can then be controlled by sending RS232 commands. The baud rate is selectable as follows: 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.

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. Click “OK” to close this window. Click “Continue” to close this window.

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, then confirmed by pressing "Enter" to send. Any response from the connected device will appear in red. (3) Select the right COM port.

Enable the keyboard type in function. Click “Play” to open the communication. Monitoring area, indicates if the command sent works. Command sending area
