Edid Extended Display Identification Data


Command	Feedback	Description
x1All	x1All	Sets selected input to all outputs
		(x3All would set input 3 to all)
x1#	x1#	Sets input to corresponding output
		(x4# would set input 4 to output 4)
All#	All#	Resets all inputs to corresponding outputs
		(input 3 to output 3, input 4 to output 4, etc...)
x1$	x1$	Turns off output channel
		(to turn off output 3 = x3$)
All$	All$	Turns off all output channels
x1Ax2	x1Ax2	Sets audio input to selected output
		(x3Ax4 = input 3 audio to output 4)
x1Ax2,x3,x4	x1Ax2,x3,x4	Sets audio input to multiple outputs
		(x2Ax1,x3,x5 = input 2 audio to output 1, 3, and 5)
x1Vx2	x1Vx2	Sets video input to selected output
		(x1Vx5 = input 1 video to output 5)
x1Vx2,x3,x4	x1Vx2,x3,x4	Sets video input to multiple outputs
		(x4Vx1,x5,x9,x12 = input 4 video to outputs 1, 5, 9, and 12)
x1AVx2	x1AVx2	Switch input to output
		(input 3 to output 5 = x3AVx5)
x1AVx2,x3,x4	x1AVx2,x3,x4	Switch input to multiple outputs
		(input 3 = x3AVx1,x2)

EDID (Extended Display Identification Data)

EDID is the standard compatibility signal passed between most sources and video displays. It allows the devices to make sure they support the same resolutions and timing.

The AT-HDDVI1616-AM has two EDID settings: default and learning. Default saves the settings of 1920x1200 resolution and 2 channel audio to all outputs. The learning setting will allow for the copying of an output’s EDID to specific inputs.

Set Up

EDID can be set up in two ways: RS-232 and the front panel.

To set up EDID through the front panel hold the <-- button for 10 seconds. Once in EDID mode to set the matrix to default press “1”. To use Learning mode and set individual EDIDs press “2”, the output number to copy, Enter, the input number to save to, and then press Enter again. Repeat the learning process for all inputs until the EDID is set up as needed.

To set up EDID through RS-232 follow the steps for RS-232 set up then use the command EDIDMx1AVx2. The x1 and x2 are place holders for output and input. If saving output 5 to input 3 the command would be EDIDMx5AVx3. Repeat until all inputs are set up.
