4.1 Setting the DIP-Switches
Set the DIP-switches to control the following functions:

DIP 1 passes the EDID or locks the entire EDID file of the connected display
at the time of the locking action (with the relevant changes done by DIP 2
and 3).
DOWN = passes EDID
Switching UP = locks the EDID of the currently connected display (with
modification according to DIP 2 and DIP 3)
UP = uses the locked EDID file (ignore the EDID of the currently connected
display)

DIP 2 controls deep color:
DOWN = passes the deep color EDID parameter (set DIP 1 ON to activate
state)
UP = limits the color depth to 8-bits per color

DIP 3 controls audio:
DOWN = passes the audio EDID parameter (set DIP 1 ON to activate state)
UP = limits the audio to 2-channel LPCM (linear pulse code modulation)

DIP 4 controls HDCP:
DOWN = passes HDCP
UP = HDCP off
Note: Color depth and audio status are activated only when
lock/modify is up.
