DDC and ID bit DIP switch settings
These two tables show the function of the DIP switches (table at left) and how the switches can affect the monitors
supported. The table at right shows some of the more common ID bit settings. Check the manual supplied with
your display to see if ID bit termination is required by your A/V system. If you are unsure, set all switches to off.

If DDC is to be used, switches 1 and 3 must be set to on and
switches 2 and 4 must be set to off.
