Device Operation
EDID Management
The AT-HDR-CAT-2 provides two EDID modes:
INT
and
LEARN
. The default EDID mode is
INT
mode. In this mode,
the AT-HDR-CAT-2 will automatically create an EDID based on the capabilities of all connected displays.
INT
mode is
recommended for the best results when the capabilities of all connected displays are unknown.
INT
mode can also
be used to select any of 9 EDID presets. Refer to
Selecting EDID Presets (page 20)
for more information on this
topic.
LEARN
mode can be used to capture an EDID from any sink device. Once the EDID is learned, it will be used
by the connected source device to determine what video and audio formats can be sent to the sink device.
1.
Power the AT-HDR-CAT-2.
2. Connect an Ethernet cable from the
HDBaseT OUT 1
port on the AT-HDR-CAT-2 to a receiver (e.g. AT-HDR-EX-
70-2PS-RX).

4.
Press and hold the
EDID
button on the AT-HDR-CAT-2. Release the
EDID
button once the
LEARN
LED indicator
begins to flash rapidly.
NOTE:
If the AT-HDR-CAT-2 is accidentally switched to
INT
mode, quickly press and release the
EDID
button to switch back to
LEARN
mode. Switching back and forth between
INT
and
LEARN
mode will not erase the “learned” EDID. In addition, switching to LEARN mode cannot be performed
if an EDID has not been learned.
IMPORTANT:
In order for EDID learning to take place, a display must be connected to
HDBaseT
OUT 1
.
Once the EDID is learned, it will be used by the connected source device to determine what video and audio
formats can be sent to the sink device(s). To switch back to
INT
mode, quickly press and release the
EDID
button.
