Sources and Destinations
The EDID memory consists of four parts:
▪
Factory
EDID list (F1-F49) the pre-programmed EDIDs, see the
in the Appendix section.
INFO Factory EDIDs do not include HDMI support.
▪
Dynamic
EDID list (D1-D2): the EDID of the last attached display device. The extender stores the last
EDID from the previously connected sink on each output port. Thus, an EDID can be shown even if
there is no device is connected to the output port at that moment.
▪
User memory
locations (U1 – U49): they can be used to save custom EDIDs.
Any EDID from the User/
Factory/Dynamic EDID lists can be copied to the user memory.
▪
Emulated
EDID list (E1): the currently emulated EDID for the input. The source column displays the
memory location that the current EDID was routed from. The source reads the EDID from the Emulated
EDID memory on the input port.
There are two types of emulation:
static
and
dynamic
.
▪
Static EDID emulation:
an EDID from the Factory or User EDID list is selected. Thus, the Emulated EDID
remains the same until the user emulates another EDID.
▪
Dynamic EDID emulation:
it can be enabled by selecting D1-D2 EDID memory. The attached monitor’s
EDID is copied to the input; if a new monitor is attached to the output, the emulated EDID is changed
automatically.
INFO DVI-OPT-TX220-Pro can handle both 128 Byte EDID and 256 Byte extended EDID structures.
