Auto Switching
Press and hold Select button at least 3 seconds at Out A block to enable auto switching mode for output A, and then the Auto LED will turns green.
Press and hold Select button at least 3 seconds at Out B block to enable auto switching mode for output B, and then the Auto LED will turns green.
When in auto switching mode, the switcher will switch according to the following rules:
- The switcher will switch to the first available active input starting at input 1 to 4.
- 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 reconnect the input before powered off.
- Source removed: When an active source is removed, the switcher will switch to the first available active input starting at HDMI input 1.
- Detection method: TMDS or 5V (The default is 5V and it can be selected by RS232 commands).
- Press the Select button can switch to next input source, and the switcher doesn’t exit the auto switching mode.
Note: In auto switching mode, press and hold the Select button at least 3 seconds to enable manual switching mode, but the input source will not be switched.
EDID Setting
The Extended Display Identification Data (EDID) is used by the source device to match its video resolution with the connected display. The 4-pin DIP switch on the front panel can be used to set the EDID to a fixed value to ensure the compatibility in the video resolution.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while putting the switch in the upper (ON) position. Switch 1~3 are used for built-in EDID setting, and switch 4 is used for mode setting. The DIP switch status and its corresponding setting are shown as below chart.
| Switch 1~3 Status | Video Resolution | Audio Format |
|---|---|---|
| 000 | Pass-through | Pass-through |
| 001 | 1920x1080@60Hz 8bit | Stereo |
| 010 | 3840x2160@30Hz 8bit | Stereo |
| 011 | 3840x2160@30Hz 8bit HDR | Stereo |
| 100 | 3840x2160@30Hz Deep Color HDR | PCM 5.1 |
| 101 | 3840x2160@60Hz 8bit | Stereo |
| 110 | 3840x2160@60Hz Deep Color HDR | PCM 5.1 |
| 111 | User-defined EDID |
| Switch 4 Status | Mode |
|---|---|
| 0 | Global Mode. |
| 1 | Out B Private Mode. |
EDID setting rules:
When switching one input to output A and output B, the switcher is used as a 1x2 splitter, the input source device obtains its EDID from the output display with priority output B>output A. If video switching fails in EDID pass-through mode, set the built-in EDID to 1080p.
- When the specifications of output A and output B display devices are same, set the EDID to Global Mode. When switch same input to output A and output B, because the supported resolution (4K@60Hz 4:4:4) of two outputs are same, the input source device will not reread the EDID of display device to ensure non-flash screen.
- When the specifications of output A and output B display devices are different, set the EDID to Out B Private Mode, and the Out A is in Pass-through mode. When switching the input source of output A to output B, because the input source device will first learn the EDID from output B, so the two output displays will flash before the image appears. When switching the input source of output B to the output A, because the input source device will first learn the EDID from output B, so the display device of output B doesnt flash, but the display device of output A will flash before the image appears.
IR Remote Control
Connect IR receiver to the IR EYE port, the switcher can be controlled by the following IR remote.
- 1-4: Press 1-4 button to select corresponding input source for OUT A. AUTO: Press the button to enable auto switching mode for OUT A.
- 1-4: Press 1-4 button to select corresponding input source for OUT B. AUTO: Press the button to enable auto switching mode for OUT B.
- De-embedded: Press A or B button to select output A or output B de-embedded audio for audio output. ARC: Press A or B button to select output A or output B ARC audio for audio output.
Web Control
The switcher can be controlled via TCP/IP. The default IP settings are:
IP Address: 192.168.0.178
Subnet Mask: 255.255.255.0
Type 192.168.0.178 in the internet browser, it will enter the below log-in webpage:
Username: admin
Password: admin
Type the user name and password, and then click Login to enter the below control tab.
- Matrix Switch: Select Input 1~4 for output A or output B to build matrix switching. Select AUTO to enable auto switching mode for output A or output B.
- Audio Out: Select output A de-embedded audio, output B de-embedded audio, output A ARC audio or output B ARC audio for Toslink and 3.5mm jack audio outputs.
RS232 Control
Connect the RS232 port to control device (e.g. PC) with RS232 cable. The switcher can be controlled by sending RS232 commands.
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“)
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 Communication 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 “”. 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. Enable the keyboard type in function. Command sending area. Monitoring area, indicates if the command sent works.
