SIGNAL TYPE
AND NAME
DESCRIPTION
Digital output
<QM_Link>
Indicates that the connection with the transmitter is present and valid. The output
will remain high for as long as the connection to the input is valid. This signal will
indicate a failure if, for example, the QM cable is disconnected or damaged.
High/1 = Connection valid at the input
Low/0 = Connection broken at the input
Digital input
<SaveSkewPreset>*
Saves the three R/G/B skew values, together with the peak and boost values, into
the preset number given by
<SkewPreset#_F>
when the input is held high.
If the save is asserted at the same time as a recall, the recall operation takes
precedence and the save is ignored.
High/1 (level sensitive) = Save skew preset
Low/0 = No preset save
All save and recall inputs are level sensitive, not edge-triggered.
Digital input
<RecallSkewPreset>*
[*This signal is operative only if automatic video compensation is NOT enabled.]
Recalls the R/G/B skew values and peak/boost values stored in the preset given
by
<SkewPreset#>
when the input is held high.
High/1 (level sensitive) = Recall skew preset
Low/0 = No preset recall
Digital Output
<SkewPreset#_F>
Reports the Skew Preset Number.
NOTE:
When
<SaveSkewPreset>
is high and
<RecallSkewPreset>
is high, then a change in
<SkewPreset#>
will trigger a recall action.
Digital input
<EnableVideoAutoComp>
The
<EnableVideoAutoComp>
digital signal enables automatic video
compensation for as long as the input is high. Refer to the Appendix on page 42
for additional information about QM Auto Compensation.
High/1 (level sensitive) = Enable auto-compensation
Low/0 = Disable auto-compensation
Digital input
<ProjFilterEnable>
The
<ProjFilterEnable>
enables the projector filter for as long as the input is high.
This turns on a built-in out-of-band noise
filter module, which improves
performance when connected to certain DLP displays.
This setting is not recommended for high-resolution monitors;
for example UXGA 1600 x1200 or 1080p.
Digital output
<ProjFilterEnable-F>
Reports the status of the projector filter feature.
High/1 = Filter enabled
Low/0 = Filter not enabled
Analog input
<SkewPreset#>*
[*This signal is operative only if automatic video compensation is NOT enabled.]
Sets the skew preset number where the R/G/B/ skew values and peak/boost
values will be saved or recalled.
Valid values range from 1d to 254d. Out of range values are ignored.
