7.3 I.D. BIT SWITCH 1& 2
Many computers use ID Bits or “Sense Pins” to
recognize that a monitor has been connected to
its video output port. Often, these ID Bits will
allow the computer to recognize what type of
monitor is connected in terms of its scan rate
compatibility. When the ID Bit switch is in the
ON position, the VA6831FC allows the main ID
Bit (pin 4 on the input connector) to be
connected to the Ground signal.
This is used primarily when interfacing laptop
computers to imitate the presence of a local
monitor. Typically, this recognition will take place
during the boot up stage. If your Interface does
not output video on the display, then place this
switch in the ON position and reboot the
computer. When left in the OFF position, this ID
Bit will be passed through to the local monitor
output port.
