4. Operation of UMX-OPT-TX150R
4.7.4. EDID Learning
Learning the EDID function enables to store the EDID of the display
which connected to the receiver in UMX-OPT-TX150R's memory.
The factory preset EDIDs cannot be changed by the user. Only
addresses #6 .. #9 (on any rotary switches) are user programmable.
ATTENTION! EDID learning is only available from the active input
to a user memory location which was selected by a rotary switch.
EDID learning is not allowed in AUTOSELECT mode.
INFO: Before a digital EDID will be selected to an analog output port
UMX-OPT-TX150R removes the digital descriptor from the EDID and
selects it.
Step 1. Connect the sink device to the unit's output (for Example the
receiver unit's HDMI OUT)
Step 2. Use a screwdriver to select an empty memory address. (for
Example on a HDMI rotary set the #6)
Step 3. Push the Learn button on the front side of the device and hold it
down for approximately 3 seconds.
Step 4. If the EDID storing was successful on the active port, the EDID
LED blinks 3 times in 3 seconds slowly then they return to their
original function. EDIDs are stored in a multiple programmable
non-volatile memory.
If the storing was unsuccessful on the active port, the EDID LED blinks
3 times in 1 second quickly then they return to their original function.
INFO: The last attached monitor's EDIDs are stored automatically,
until a new monitor is attached to the output (or receiver's output).
In case of powering the unit off, the last attached monitor's EDID
remains in non-volatile memory.
4.7.5. EDID Switching
Use a screwdriver to change the memory address on the rear side of
the UMX-OPT-TX150R.
After any of the rotary switches has been rotated, the unit waits
approximately 2 seconds before the selected EDID becomes active.
The address #0 (on any rotary switches) has a special function. If a
receiver is connected to the output, then its EDID is copied to the input
connector. If no receiver is connected to the output then the EDID
transmitted to the input connector is the EDID of the last connected
monitor.
UMX-OPT-TX150R – User's Manual
INFO: After every EDID change, UMX-OPT-TX150R 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.
ATTENTION! Switching EDID for any inputs is available only with
rotary switches. (Switching with protocol command is not available,

Software see Changing Emulated EDID
4.8. HDCP Management
The UMX-OPT-TX150R can work as a HDCP compliant device, or act
as a non-HDCP compliant sink. The HDCP capability can be disabled
or enabled on the digital video input ports (DVI-D, HDMI). This function
helps to apply encryption only when it is mandatory.
Some video sources send encrypted signal when they are connected
to a HDCP capable device even if the content is not protected. This
way even the unprotected content cannot be displayed on non-HDCP
displays if the signal travels through a HDCP compliant matrix or
repeater.
However HDCP encryption is not required all the time (e.g. computer
desktop image) some video cards still encrypt if they detect that the
sink is HDCP capable.
Avoiding Unnecessary HDCP Encryption
If HDCP is disabled on any digital video input port, the connected source
will detect that the sink is not HDCP capable, and turn off authentication.
The source will not be able to communicate with any of the devices
(displays, repeaters, etc.) that are connected to the receiver's output,
therefore it could not see if they are HDCP capable or not.
This forces the source to send unprotected signal only. If HDCP
capability is disabled on an input port, the connected source cannot
send protected content to any display. If HDCP function is enabled on
an input port and the source sends encrypted signal, the non-HDCP
compliant devices cannot display the video.
INFO: In HDCP disable mode, protected content (i.e. Blu-ray disc)
will not be displayed, thus maintaining the rules set by the HDCP
standard.
To toggle the HDCP function on the desired input port, use Lightware
Device Controller software (HDCP Enable) or turn the desired digital
input's rotary switch to address #1, and press and hold the Learn
button for approximately 5 seconds.

HDCP Key Counter
HDCP key counter is a tool that counts and validates the number of
keys that can be accepted by a source device when connected to an
HDCP repeater.
HDCP key counting is available with protocol command. For more
information, see
4.9. Reload Factory Defaults
Factory default settings can be reloaded with the procedure below:
DVI-D DVI-A
Turn all of the rotary switches to address #0, and press and hold the
Learn button for approximately 10 seconds.
After restoring default values press the Reset button to reboot the
device. This operation affects the crosspoint table and configuration,
I/O settings and stored User and Dynamic EDIDs and the RS-232 mode.
This process can be induced by protocol command as well. For more
information see
WARNING! User and Dynamic EDIDs will be cleared (refilled with
Lightware Universal EDID) after reloading the factory defaults.
WARNING! Reloading factory defaults by rotary switches plus
learn button AFFECTS the serial operation mode and the RS-
232 baud rate options as well. The default operation mode is
the PASS mode and the default baud rate is 57600 baud in the
UMX-OPT-TX150R. If the previous serial settings differ from the
default ones, please set up the necessary values after reboot with
protocol commands. (See details about the protocol commands
