5. DIP SWITCH OPERATION:
The 4-pin DIP switch on the front panel of the unit is used for EDID
management and HDCP management. It 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 EDID setting. The switch status and its corresponding setting are
shown at the below chart.
Switch 4 is used for HDCP setting. The switch status and its corresponding setting are shown
at the below chart.
Switch 4 Status HDCP
OFF (0)
Automatically follows the HDCP version of display device.
When display device has no HDCP, if source device have no HDCP
content, the video output has no HDCP content; if source device has
HDCP content, there are no video output.
ON (1) Automatically follows the HDCP version of source device.
Note: The factory default switch status is “0000”, and it needs to be set to “1111” when enable
RS232 control to set EDID and HDCP.
6. RS232 CONTROL
Connect the RS232 port to control device (e.g. PC) with RS232 cable. The splitter can be
controlled by sending RS232 commands.
RS232 Commands
The command lists are used to control the splitter. 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, bound
rate, data bit, stop bit and the parity bit correctly, and then you are able to send command in
command sending area.
Baud rate: 9600
Data bit: 8
Stop bit: 1
Parity bit: none
Note:
• All commands need to be ended 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.

7. FIRMWARE UPGRADE
Please follow the below steps to upgrade firmware by the Micro-USB port:
1. Prepare the latest upgrade file (.bin) and rename it as “FW_MERG.bin” on PC.
2. Power off the splitter and connect the Micro-USB (FW) port of splitter to the PC with
USB cable.
3. Power on the splitter and then the PC will automatically detect a U-disk named of
“BOOTDISK”.
4. Double-click to open the U-disk, a file named of “READY.TXT” will be showed.
5. Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk.
6. Reopen the U-disk to check whether there is a filename “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.
7. Remove the USB cable and reboot the splitter after firmware upgrade.
