Auto Switching Fuction:
Press the button "input 1" for 2 seconds, the AS-41V will jump to the "Auto-Switching" function.
The LED of "Auto-SW" in the front panel will be on and vice versa.
Auto-Switching principle
1: Priority of the new connection:
When you connect a new valid VGA source to the AS-41V, under Auto-Sw mode, the AS-41V will switch to this
new source.
2: Priority of power reboot or VGA signal removing:
When the power is rebooted under the auto-Sw mode, the AS-41V will detect the 4 VGA inputs, ranging from
input1, input2, input3, input4. When it finds a valid VGA signal, it will switch to this channel.
When the displaying input is removed under the auto-Sw mode, the AS-41V will detect the 4 VGA inputs, ranging
from input1, input2, input3, input4. When it finds a valid VGA signal, it will switch to this channel.
