Video to VGA Converter/Switch 

12

 

the DVD player has louder output than the VCR, you can balance 
(equalize) the volume settings using the serial input control so that 
when you switch from one input to another the output volume level 
stays the same.  

Special Front Panel Operations 

 

To enter the “Auto” mode from the front panel press the left 
two switches (VGA and CV1) simultaneously for 1 second. In 
auto mode if there are no TV inputs, the unit selects the PC 
input. As soon as it detects a valid TV input on any of the 

video inputs, the AC135A-R2 switches to the TV input. (The TV 

inputs have priority over the VGA input from the PC; there is 
no priority structure among TV inputs as soon as a valid TV 
signal is found on CV1, CV2, or S-Video, the unit selects it 
and stays on it as long as the video signal is present. 

To reset the system to factory default settings, press the left 
and right switches (VGA and S-Video) simultaneously for 3 
seconds. The system will reset to factory settings. This 
capability is available even if the front panel has been locked.
