Command Description
DIDU Applies an EDID file loaded with
DIDL to the Rx and issues a hot
plug pulse.
Note: can be used in conjunction
with the HPPW command to
produce hot plug pulses of varying
witdths.
HPPW Sets the hot plug pulse width.
IFAU Reads infoframes.
IFAD? Displays the contents of a specific
type of infoframe.
TMAU Invokes timing analyzer.
TMAX:HTOT? Reads horizontal total pixels.
TMAX:HRES? Reads horizontal active pixels.
TMAX:HSPD? Reads horizontal sync pulse delay
TMAX:HSPW? Reads horizontal sync pulse width
Reads vertical total pixels (lines)
TMAX:VTOT?
TMAX:VRES? Reads vertical active pixels (lines)
Reads vertical sync pulse delay
TMAX:VSPD?
Note: The commands are not case sensitive.

Command Example
To load an EDID file, apply it to the
Rx port and issue a hot plug pulse:
DIDL my720p.xml
DIDU
Where pulse can be within the
range of:
100 to 4000 milliseconds
Not applicable
Where infoframe packet is the
header number assigned to the
infoframe type in the HDMI
specification:
- VSIF = 81
- AVI = 82
- SPD = 83
- AUD = 84
- MPEG = 85
To initiate a timing test:
TMAU
Note: Then use one or more of the
TMAX commands below.
To read horizontal total pixels:
TMAX:HTOT?
To read horizontal active pixels:
TMAX:HRES?
To read horizontal sync pulse
delay:
TMAX:HSPD?
To read horizontal sync pulse
width:
TMAX:HSPW?
read vertical total pixels (lines):
TMAX:VTOT?
To read vertical active pixels
(lines):
TMAX:VRES?
To read vertical sync pulse delay:
TMAX:VSPD?
