The 2A-130G VGA EDID Emulator is designed for ATEN KVM extender or video extender installations that do not utilize a local monitor at the site where the computer/video source is located. The 2A-130G emulates and stores a default ATEN EDID (Extended Display Identification Information) setting in a non-volatile memory. This means the computer/video source can still "see" the display, even though it is not directly connected.
