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.
