SW DVI Plus Series • Operation 16 16
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 15 EDID files that are loaded
on the switcher at the factory. Each EDID file contains a unique native resolution. The
table below shows the EDID files that are provided with the switcher.
• User-loaded EDID file — In addition to the 15 EDID files provided with the switcher, an
empty location (16) is provided, to which you can save the EDID data of the display that
is currently connected to the output port of the switcher. This sixteenth file can then be
selected as one of the available EDID files.
The table below lists the EDIDs that are available to be assigned by the user.

Changing the EDID mode
EDID modes can be switched only by SIS command. By default, the SW DVI Plus 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 0 (automatic mode) or the number of the EDID file that you want to select
( 1 through 16 ). (See the “ Remote Configuration and Control ” section, beginning on
page 18, for instructions for entering SIS commands via RS-232.)
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.
