Locking and Unlocking the Front Panel (Executive Mode)
Front panel lock mode disables all front panel controls, locking out users from those
functions (RS-232, USB, and IR control remain available). Putting the switcher in lock mode
enhances security by protecting against inappropriate or accidental changes to settings. If
a front panel button is pressed during lock mode, all front panel LEDs blink once.
To lock or unlock the front panel, press and hold Input buttons 1 and 2 simultaneously for
3 seconds, then release. The front panel LEDs blink three times, indicating that executive
mode has been enabled or disabled (see figure 13).

EDID Modes
The SW HDMI switchers utilize the EDID Minder, which maintains EDID communication to
all connected sources, whether or not any of the sources are selected. EDID information
consists of the display resolution, refresh rate, data rate, supported audio formats, and
other features. By factory default, the EDID stored on all inputs contains information for a
native resolution of 720p @ 60 Hz, 2-channel audio.
EDID Minder can be configured in two modes: automatic and user-assigned.
Automatic EDID mode
In automatic mode, the switcher automatically stores EDID from the connected display and
communicates it to the inputs; no other configuration is required. This is the default mode.
• Reading and storage process — Each time a display is connected to the HDMI
output while the power is connected, the SW HDMI reads the EDID from the display
device and stores it in memory for each input. This information is retained after the
display is disconnected; however, it is overwritten if a new display is connected or a
user assigned EDID file is selected.
• Default EDID — When the switcher is in automatic mode, the default EDID
(720p @ 60 Hz) is stored at each input until a display is connected, at which time it is
overwritten.
