Device Operation
EDID Management
The AT-UHD-CAT-4ED provides two EDID modes:
INT
and
LEARN
. The default EDID mode is
INT
mode. In this
mode, the AT-UHD-CAT-4ED 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 16 EDID presets. Refer to
Selecting EDID Presets (page 16)
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-UHD-CAT-4ED.
2. Connect an Ethernet cable from the
HDBaseT OUT 1
port on the AT-UHD-CAT-4ED to a receiver (e.g. AT-UHD-
EX-100CE-RX).
3. Connect an HDMI cable from the receiver to the display (sink) device. Make sure that the sink device is powered.
