Capture an output
EDID to custom slot
ESX@*X1(EDID} EdidSX@*X1(]
Capture output X@ EDID to X1(
(Valid for X1( = 3, 4, 5, 6, 7 only and X@ =
1 or 2 only.)
Export EDID file
EEX1(,<filename>
EDID}
EdidEX1(]
Exports EDID table X1( to <filename>.
Import EDID file
EIX1(,<filename>
EDID}
EdidIX1(]
Imports EDID table X1( from
<filename>.
Import valid for
X1( = 3, 4, 5, 6, and 7.
NOTE: <filename> can optionally carry a full path name: EDID file format is “bin” carrying 128 or 256 bytes of binary
data.
Exporting a default EDID table (for an X1( value of 10 or greater) results in the “digital” “2CH Digital” table
being exported.
NOTE: X! = Input number: 1 through 5
X@ = Output selection: 0 = All outputs (default), 1 = Analog (VGA, YUVp, HDTV), 2 = HDMI, 3 = 3G/HD-SDI, 4 = None
X# = Input video format: 0 = No signal detected, 1 = RGB, 2 = YUV auto, 3 = RGBcvS, 4 = S-video, 5 = Composite,
6 = DVI/HDMI (only available for inputs 3, 4, and 5), 7 = Auto detect (default for inputs 1 and 2)
X1( = Scaler resolution/EDID emulation, 0 = Automatic: match current output resolution (default),1 = Output 1 analog
VGA connector, 2 = Output 2 HDMI connector, 3 = Custom EDID/output rate 1, 4 = Custom EDID/output rate 2,
5 = Custom EDID/output rate 3, 6 = Custom EDID/output rate 4, 7 = Custom EDID/output rate 5.
