3.9. EDID and DIP Switch Settings
Every digital display has extended display identification data (EDID) that describes its
capabilities to a video source. This enables the source to know which type of display is
connected to it, and to send compatible signals to that display.
The EDID settings of any display can be relayed to any source by means of a DIP
switch located on the back panel of the Matrix Switch (Figure 10). The DIP switch has
three contacts (1, 2, 3), each of which can either be set up (OFF) or down (ON).

Various DIP switch settings enable the user to relay any display’s EDID to any source.
Table 5 shows 8 pre-defined DIP switch settings and the function of each.

Notes:
1. To relay the EDID of display x to source y, the user must first ensure that source y
is currently selected for display x. The user then presses on the square pushbutton
of display x (located on the front panel of the Matrix Switch) for 3 seconds. The
EDID of display x has now been relayed to source y.
Example: To relay the EDID of display 4 to source 1, first ensure that display 4 is
currently selecting source 1. Next, press on the square pushbutton of display 4 for
3 seconds. The EDID of display 4 has now been relayed to source 1.
2. Selected fixed EDID will be active only after a power cycle of the Matrix Switch.
