4. Panel Button Control
4.1 I/O connection switching
The front panel features four input selection buttons and four output selection buttons
for switching I/O connection.
1) To convert one input to an output:
Example: Input 1 to Output 3
→ Press INPUTS 1 + OUTPUTS 3
2) To convert an input to several outputs:
Example: Convert Input 2 to Output 3 and 4
→ Press INPUTS 2 + OUTPUTS 3 + OUTPUTS 4
NOTE: Indicators of the pressed buttons will blink green for three times if the
conversion is done, then it will be off. If the conversion failed, they will be off
immediately.
4.2 EDID Configuration
The rear panel boasts a 4-pin EDID DIP switcher to manage EDID. The EDID data and
its corresponding DIP switcher status are shown in the below list.

corresponding front panel buttons
④ Menu buttons: ALL, EDID, CLEAR and ENTER.
l ALL: Select all inputs/outputs.
To convert an input to all outputs:
Example: Input 1 to all Outputs:
→ Press INPUTS 1 + ALL + ENTER
l EDID management button:
1) One input port learns the EDID data from one
output port.
Example: Input 2 learns EDID data from output 4:
→ Press EDID + INPUTS 2 + OUTPUTS 4+ ENTER
2) All input ports learn EDID data from one output
port.
Example: All input ports learn EDID data from output 3:
→ Press EDID + ALL + OUTPUTS 3 + ENTER
l CLEAR: Withdraw button.
l ENTER: Confirm operation.
