5. Button Control
5.1 Manual Switching
When the switcher is in manual switching mode, the AUTO button LED goes out.
Please follow the below steps to switch input source to output channel.
1) Press Select button at Out A block to select input source for output A, and the
corresponding source LED turns green.
2) Press Select button at Out B block to select input source for output B, and the
corresponding source LED turns green.
5.2 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.

5.3 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.

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.
1) 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.
2) 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 doesn’t flash, but the display device of output A will flash before the
image appears.
