4.4.2. Learning the EDID (TX200R)
The factory preset EDIDs cannot be changed by the user. Only addresses #51..#99 are
user programmable.
Info HDMI-OPT-TX200R can learn EDID with LEARN BUTTON from local HDMI output called
MONITOR OUT.
After connecting the sink device to the TX200R
’s MONITOR OUT use a screwdriver to
select an empty memory address. EDIDs are stored in a multiple programmable non-
volatile memory.
If the red EDID status LED (EMULATED EDID INVALID LED) is illuminated, then the
memory slot is empty and ready to be programmed. If the green EDID status LED
(EMULATED EDID VALID LED) is illuminated, the memory was already used before, but
still available for programming.
Push the LEARN button on the front side of the device 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 four times and stays illuminated. Now the
stored EDID is automatically emulated.
If the storing was unsuccessful, the red EDID status LED blinks four times and either the
red or green EDID status LED becomes illuminated, depending on the previous status of
the selected EDID address.
Info
The last attached monitor’s EDIDs are stored automatically, until a new monitor is
attached to the MONITOR OUT. In case of powering the unit off, the last attached
monitor’s EDID remains in non-volatile memory.
Info As a matter of fact TX200R always learns
the stored last attached monitor’s EDID into the
user programmable EDID memory.
4.4.3. Switching the EDID
Use a screwdriver to change the memory address on the front side of the
HDMI-OPT-TX200R/TX100R/TX100.
After either one of the rotary switches has been rotated, the unit waits approximately 2
seconds before the selected EDID becomes active. If the EDID status is unchanged the
EDID status LEDs do not blink, but stay continuously lit.
The address #00 has a special function in case of TX200R. If a monitor is connected to
the MONITOR OUT, then its EDID is copied to the HDMI INPUT connector. If no monitor
is connected to the MONITOR OUT then the EDID transmitted to the INPUT connector is
the EDID of the last connected monitor.
Info If an invalid EDID is selected, the TX200R/TX100R/TX100 does NOT give a HOT PLUG
signal to the HDMI INPUT.
Info After every EDID change, TX200R/TX100R/TX100 toggles the HOT PLUG signal for
approx. 1 second. Some graphic 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.
