Operation of DVI-TP-TX200DL
3.1.
When building an electronic system, make sure that all of the devices are powered
down before connecting them. Powered on devices may have dangerous voltage
levels that can damage sensitive electronic circuits.

Info
If none of the LEDs light up upon power-up, the unit is most likely damaged and
further use is not advised. Please contact
3.2.
The factory preset EDIDs cannot be changed by the user. Only addresses from 51
to 99 are user programmable.

Power
After the system is complete, connect the output of the +5V Power Adaptor
to the DVI-TP-TX200DL (further on TX200DL) The unit is immediately
powered ON.
After being powered on, the TX200DL displays its firmware version using the
EDID Status LEDs.
The following example shows this process for a firmware version of 1.3.7
RED blinks once → Short pause → GREEN blinks three times → Short
pause → GREEN blinks seven times → Short pause → The normal function
of the LED is in effect.
After indicating the firmware version, the red EDID status LED lights up for 2-
3 seconds, then turns green if the selected EDID is valid, or remains red, if
the selected EDID is invalid (or the selected memory slot is empty).
After the TX200DL is initialized, the attached DVI source and monitor can be
powered on.
If a display device is connected to MONITOR OUT, the TX200DL reads the
EDID from the attached monitor's EDID memory.
If the read process is successful, the GREEN LED blinks several times then
the EDID Status LEDs show whether the selected EDID is valid (green) or
not (red) on the DVI INPUT connector.
If the read process is unsuccessful, the RED LED blinks several times then
the EDID Status LEDs show whether the selected EDID is valid (green) or
not (red) on the DVI INPUT connector.
Learning the EDID
After connecting the sink device to MONITOR OUT, use a screwdriver to
select an empty memory address. EDID are stored in a multiple
programmable non-volatile memory.
If the red EDID status LED is illuminated, then the memory slot is empty and
ready to be programmed. If the green EDID status LED is illuminated, the
memory was already used before, but still available for programming.
Push the LEARN button on the front side of the TX200DL and hold it down
for approximately 3 seconds.
Once the button is pushed the EDID status LEDs go dark. If the EDID storing
was successful, the green EDID status LED blinks five times and stays
illuminated. Now the stored EDID is automatically emulated.
If the storing was unsuccessful, the red EDID status LED blinks five times
and either the red or green EDID status LED becomes illuminated,
depending on the previous status of the selected EDID address.
