INputLOAD <input #> <1…160> Loads the indicated entry from the Timing List to
the specified input channel. Timing list entries from
1 to 99 are reserved for factory defined timing
parameters. Entries from 100 to 160 are available
for user defined timing entries.
The entry is loaded only if it matches the measured
signal parameters — sync format and polarity,
interlace state, vertical total, and horizontal
frequency.
INputNAME <input #> [timing set
name] Names the specified input. The argument can be up
to 23 alphanumeric characters with no spaces (use
underscore for space).
Default: Auto_1
INputPHASE <graphics input#> [0 … 31] Adjusts the phase of the Analog/Digital Converter
to optimize picture quality. Applies to Analog RGB
inputs only.
Default: 24
INputSAVE <input#> <100…160> Saves the input timing parameters for the specified
input to the selected entry in the Input List.
Whenever a signal is applied to the graphics input
the signal parameters are measured and compared to
entries in the list. When a match is found it is
applied to the
Quadra .
INputSouRCe <input#> [RGB | DVI |
YUV | COMPOSITE1 |
COMPOSITE2 | SVIDEO] Selects the analog or digital graphics source for the
specified input.
Default: RGB
INputTiMing <input #> [<hfp> <hs>
<hbp> <hact> <vfp> <vs>
<vbp> <vact>] | [HFP | HS
| HBP | HACT | VFP | VS |
VBP | VACT] [value] Defines the active area of the input signal and the
selected input’s timing. Using this command, the
user can set all timing parameters as query or set the
value of an individual parameter. For example to
query the value of vertical sync width issue the
command
INTM VS .
Horizontally, the active part of the signal is
<hact> . The inactive part (h blanking) is <hfp>
+ <hs> + <hbp> . The total number of pixels
horizontally is htotal = (h blanking) + <hact> .
Note that the pixel clock frequency = hfreq x
htotal so changing the total horizontal pixel
count ( htotal ) will directly change the frequency
of the sample clock.
The active part of the vertical component of the
signal is
<vact> . The inactive part (v blanking) is
<vfp> + <vs> + <vbp> . The total number of
lines is vtotal = (v blanking) + <vact> . Since
Quadra knows the total line count an error will
result if the sum of the active and inactive parts
entered in the command do not match the measured
total line count.
Refer to the “ Timing Parameters ” section for
details on timing parameters.
