INFO: The device does not check if the connected sink (monitor,
projector or other equipment) supports hotplug or EDID signals but
outputs the input signal directly.
DVI-DL Input
The input has Dual-Link disable option, which ensures Single-Link
compatibility. Devices supporting Dual-Link output can confuse
Single-Link inputs; disabling the Dual-Link TMDS channel distribution
solves this problem. For more information see Output Port Properties
section.

Status LED lights up depending on the selected EDID’s validity:
–Red – ‘N’: the selected EDID is invalid.
–Green – ‘Y’: the selected EDID is valid
Step 3. If a display device is connected to DVI-DL OUTPUT 1, the
DA2DVI-DL reads the EDID from the attached monitor’s EDID
memory.
–If the read process is successful, the STATUS LED blinks
green four times.
–If the read process is unsuccessful, the STATUS LED blinks
red four times.
Step 4. The normal function of the LEDs is in effect.
WARNING! If none of the LEDs light up upon power-up, the unit is
