User-assigned EDID mode
In this mode, you can select an EDID file that is stored on the switcher at the factory.
The selected EDID is stored at the inputs and is not overwritten; the switcher does not
automatically obtain EDID information from the display.
You may want to use this mode if there is a problem with automatic communication of
the EDID information from the attached display, and you want to ensure that the correct
information is stored on the inputs. Also, because this mode disables automatic EDID
reading and storage, you can retain one set of EDID information on the inputs and not
have it changed when another display is connected.
Factory-loaded EDID files — You can select from a list of 46 EDID files that are
•
loaded on the switcher at the factory. Each EDID file contains a unique native
resolution and audio support (if applicable). The
the EDID files that are provided with the switcher.
• User-loaded EDID file — In addition to the 46 EDID files provided with the switcher,
four empty locations (47 through 50) are provided. To these slots you can save the
EDID of the display that is currently connected to the output port of the switcher. Any
of these four files can then be selected as one of the user-assigned EDID files.
Changing the EDID mode
EDID modes can be switched only by SIS command. By default, the SW HDMI is in
automatic EDID mode. To change between automatic and user-assigned modes, enter the
following SIS command:
E X% }
A * EDID
where X% is
0 (automatic mode) or the number of the user-assigned EDID file that you
want to select ( through
1 50
for instructions for entering SIS commands via RS-232 or USB).
NOTE: The switcher remains in the selected EDID mode after power is recycled. If the
unit is reset to factory defaults, it reverts to automatic mode.
