System Diagram

Multi-view Mode Selection

There are four multiview modes that can be selected using the front panel buttons. The factory default multi-view mode is quartered window mode, and there is a one-one correspondence between the four input sources and the four output windows: input 1 -> window A, input 2 -> window B, input 3 -> window C, input 4 -> window D. The button LEDs (A~D) illuminate blue.
When switching to two-window (A&B) mode, the corresponding mode LED will illuminate blue, and the window A and B LEDs illuminate blue. The factory default correspondence between the two input sources and the two output windows is: input 1 -> window A, input 2 -> window B.

Full Screen Setting

Press A~D window buttons to select the corresponding window to display in full-screen. Meanwhile, the corresponding input source button LED and window button A LED both illuminate blue, other window buttons and the previous multiview mode button LED turn off.

Swap Window Setting

Press the SWAP button to cycle through the video sources of the windows display in anticlockwise direction. The SWAP LED illuminates once when its corresponding button is pressed.
Example: In Multiview Mode
Example: In Full Screen Mode

Window Size Setting

The window A/B/C/D size can be adjusted by repeatedly pressing the RESIZE button. The button LED illuminates once when its button is pressed once. Please refer to the GUI Multiview Tab for more details.
Example: PIP (Picture in Picture)
Example: Bisection

Example: One Large and Three Small

Video Signal Switching

• In the multiview mode Operation: Inputs# + Windows# Example: Switch Input 1 to Window B: Press INPUT 1 (The input 1 LED illuminates blue, the windows A~D LEDs flash.) Press Windows B (The windows A, C and D LEDs turns off, then input 1 and windows B LED flash three times, last, input 1 LED turns off and windows A~D LEDs illuminate blue.)
• In Full Screen Mode
• 1) Manual Switching Operation: Inputs# + Windows# Example: Switch Input 2 to Window A: Press INPUT 2 (The input 2 LED illuminates blue.) Press Windows A (The input 2 and windows A LEDs illuminate blue).
• 2) Auto Switching Press AUTO button to enable or disable auto-switching mode. Note that auto-switching mode only works in full screen mode.

When in auto-switching mode, the switcher will switch according to the following rules:

• The switcher will switch to the available active inputs with the priority: 1-HDMI > 2-HDMI > 3-HDMI > 3-DP > 4-HDMI > 4-USB-C. When input source and output window are connected, the corresponding LEDs illuminate blue.
• New input: The switcher will automatically select the new input once detecting a new input.
• Reboot: If power is restored to the switcher, it will automatically reactivate the input that was active before it was powered off.
• In auto-switching mode, the input source also can be switched by the manual switching steps, but not exit auto-switching mode.
• When full screen mode is switched into multi-view mode, the auto-switching mode will not exit.

Video Switching Status Inquiry

In the multiview mode (Window A, B, C and D LED illuminate blue).
Operation: Windows#
Example: Press and hold Windows B button at least 3 seconds (Window A, C and D LED go out, and then the corresponding input source LED will illuminate blue). After 3 seconds, Window A, B, C and D LED illuminate blue.

Audio Control

By default, the HDMI and HDBT output audio follows the video source in the full screen mode, but in the multiview mode, the output audio is embedded from the 1-HDMI input. The audio source can be changed by pressing the SOURCE button.

Press the volume knob to select microphone or source audio control. Rotate the knob to increase or decrease the volume of the selected audio. Press and hold the knob at least 3 seconds to mute the selected audio, rotate the knob to unmute.

Select the desired update file and press “Apply” to start upgrade.

Caution: Please don’t do anything during the upgrade process to avoid upgrade failure.

RS232 Control

The RS232 port on the switcher has two control methods.
1) Local control: Connect the RS232 port to control device (e.g. PC) to control the switcher by RS232 commands.
2) Display device control: The RS232 signal is passed through to the RS232 port of the connected HDBaseT receiver to control the display device (e.g. projector) connected to the receiver.

RS232 Commands:
The command lists are used to control the switcher. The RS232 control software (e.g. docklight) needs to be installed on the control PC to send RS232 commands.
After installing the RS232 control software, please set the parameters of COM number, baud rate, data bit, stop bit and the parity bit correctly.
Baud rate: 9600
Data bit: 8
Stop bit: 1
Parity bit: none

Note: All commands need end 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.

RS232 Control Software

We are using 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.

(1) In order to be able to send commands, open communication with the device by clicking on "Play".
(2) Then the keyboard function must be activated, so that commands can be written in the "communication window".
(3) 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.
Select the right COM port.

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