cause they might cause permanent damage to the rotary switches.
Step 1. Use a screwdriver to change the EDID ADDRESS by the rotary
switches on the front panel of the DA2DVI-DL.

EDID status Y lights in
green.
EDID status N lights in
red.
The address #00 has a special function. If a monitor is connected to
OUTPUT 1, then its EDID is copied to the DVI-DL INPUT connector. If
no monitor is connected to the OUTPUT 1 then the EDID transmitted to
the INPUT connector is the EDID of the last recognized monitor.
ATTENTION! If an invalid EDID is selected, DA2DVI-DL does NOT
give a HOT PLUG signal to the source connected to DVI-DL INPUT.
INFO: After every EDID change, DA2DVI-DL toggles the HOT PLUG
signal for approximately 2 seconds. Some graphics cards or DVD
players do not sense the HOT PLUG signal, and even if EDID has
been changed, the set resolution is not affected. In this case the
source device must be restarted, or powered OFF and ON again.
4.2.3. Learning the EDID
ATTENTION! The factory preset EDIDs cannot be changed by the
user. Only addresses from #51 to #79 are user programmable.
Step 1. After connecting the sink device to DVI-DL OUTPUT 1, use a
screwdriver to select a user programmable memory address.
EDIDs are stored in multiple programmable non-volatile
memories.
