AT-RON-448
The AT-RON-448 provides two rack ears, which can be used to mount the unit in a standard rack
unit.
Mounting Instructions
The AT-RON-448 provides two EDID modes: internal (INT) and LEARN. Internal mode selects
the highest common resolution and audio between the source and all displays.
LEARN mode will copy the EDID information of the display/sink connected to the HDMI OUT 1
port.
To learn and EDID from the connected sink, press and hold the EDID button. While the EDID is
being learned, the LEARN LED will blink. EDID learn is complete when the LEARN LED glows
solid blue.
EDID
NOTE: 4K, 3D, and multichannel audio may not be available when using INT
(internal) EDID mode. When using this mode, the AT-RON-448 will build an
EDID, based on the capabilities of each display that is connected.
1. Remove the front two case screws from the sides of the case.

Troubleshooting
Problem Solution
How do I perform a
rmware update on the
AT-RON-448

Does the Rondo
series provide external
automation control?
No.
3D content is not being
displayed.
• If using INT (internal) EDID mode, all connected displays
must be able to display 3D content. If only one of the
connected displays is not 3D-capable, then none of the
displays will show 3D content.
• To pass 3D content when not all displays support 3D,
connect a 3D display to Output 1, then use the “learn
EDID” procedure.
