SW HDMI Series • Operation 18
User-assigned EDID mode
In this mode, you can select an EDID file that is stored on the switcher. The selected EDID
is stored in memory for the inputs and is not overwritten. The switcher does not 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 48 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 EDID table on the next page shows
the EDID files that are provided with the switcher.
• User-loaded EDID file — In addition to the 48 EDID files provided with the switcher,
four empty memory locations (50 through 53) are provided. You can use these
memory locations to save the EDID of the display that is currently connected to the
output port of the switcher. Any of these four EDID 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
A
X$
EDID
}
where
X$
is 49 (auto mode) or the number of the user-assigned EDID file that you want to
select (1 through 53) (see the Remote Communication and Control section, beginning
on page 21, 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.
See the table on the next page for a list of supported EDIDs.
