DIP SWITCH Function

1 IR Channel

2 IR Channel

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.
