SELECTION BUTTONS: Four sets of six buttons for 
selecting which inputs are assigned to each of the 
four outputs. For direct selection, press the number 
corresponding to the desired input in the desired 
output section. You can also use the two arrow 
buttons to cycle to the next or previous input. 

 
 
 
 

EDID MANAGEMENT 

Prior to installing the matrix/extender, you need to set the EDID DIP switches to control 
the EDID information that will be sent to your source devices. EDID is an acronym for 
Extended Display Identification Data, which is the method by which the display reports its 
maximum resolution and audio capabilities to the source device, so that it can output the 
proper resolution and audio type. If the source device outputs a resolution too high for the 
display, the display will be blank. Similarly, if it tries to output too many audio channels, 
you will only hear part of the audio signal. 
Normally, the source device is connected directly to the display and this operation takes 
place automatically without you even noticing it. However, since this matrix allows 
connection of up to eight displays, each of which may have different capabilities, the 
sources have no way of knowing which resolution and audio settings to use. The EDID DIP 
switches solve this dilemma by providing each source with a fixed capability, so it always 
know which resolution and audio types to output. 
Perform the following steps to set the EDID switches on the matrix/extender, prior to 
installing the system.
