3 EDID Mode
4 EDID Lock Mode
Use DIP switch 3 to set the desired EDID mode.
1. LOCAL EDID Mode (Switch 3=OFF) DEFAULT
• EDID that is stored in the LOCAL memory location is passed to all inputs.
• By default, during each power-on process the connected display’s
EDID will be automatically copied to each of the inputs’ LOCAL EDID
locations.*
• The EDID stored in the LOCAL locations can be overwritten with another
EDID from the following locations (These options can only be initiated by
using RS-232 serial communication commands) :
• Built-in EDID memory bank (up to 7 EDID records can be stored)
• EDID collected directly from the input display*
• Externally uploaded via the RS-232 command set (see p. 13)
*For the default EDID writing process to be successful the connected display
must be powered on.
2. DS (Down Stream) EDID Mode (Switch 3=ON)
• EDID is passed directly from the connected display to the currently active
input. Note: HDCP is supported in this mode only.
3. EDID Lock Mode (DIP Switch 4 = ON)
• Locks the last stored EDID, even if the unit is power-cycled. To store a
new EDID, do the following:
1. Power-down the Switcher and set DIP Switch 4 to the OFF position.
2. Connect the display to the DVI output port then power-on the Switcher.
3. Set DIP Switch 4 to the ON position to lock the EDID.
