4 Auto Switching
WHD4 has auto switching mode and manual switching mode, the former means WHD4 will keep
detecting input signal and switch automatically once detecting a new signal under this mode, and it
follows 3 priority principles:
1
st
Priority: New input principle
Once detecting a new input signal WHD4 would switch to this new signal automatically. For
example, if WHD4 is displaying signal from input 3, but it would switch to input 4 if you connect
a new source to this input.
2
nd
Priority: Power rebooting principle
Once rebooting, WHD4 will memorize its last display and switching mode thanks to its power
fail memory function. But WHD4 will detect HDMI input signal again with priority from input 1 to
input 4 once it can’t detect the last input (this happens when you remove the last displaying
signal as it is powered off).
3
rd
Priority: Signal removing principle
Once removing the current display signal, WHD4 will detect HDMI input signal with priority
from input 1 to input 4.
These two modes can be set by button or by RS232 command (auto switching mode is our factory
default), operations are as below:
1) Button control:
a) By pressing button INPUT 1 for 3 seconds, you can set WHD4 from auto switching
mode to manual switching mode (“Auto-SW” LED will be off).
b) Same as above operation if you want to set it from manual switching mode to auto
switching mode (“Auto-SW” LED will be on).
2) RS232 control:
a) By sending command 602%, you can set WHD4 from auto switching mode to manual
switching mode (“Auto-SW” LED will be off)
b) By sending command 601%, you can set WHD4 from manual switching mode to auto
switching mode (“Auto-SW” LED will be on)
