QuickMedia™ Receiver/Processor Crestron
QM-RMCRX-BA
Video Output Control Signals (continued)
SIGNAL TYPE AND NAME
DESCRIPTION
Digital input
<EnableVideoAutoComp>
Enables automatic video compensation for as long as the input is high.
High/1 (level sensitive) = Enable auto-compensation
Low/0 = Disable auto-compensation
Digital input
<ProjFilterEnable>
Enables the projector filter for as long as the input is high. This turns on the
out-of-band noise filter module built into the QM-RX, which improves
performance when connected to certain DLP displays.
This setting is not recommended for high-resolution monitors; for example,
UXGA (1600x1200) or 1080p.
High/1 (level sensitive) = Enable projector filter
Low/0 = Disable projector filter
Digital input
<ProjFilterEnable_F>
Reports the status of the projector filter.
High/1 = Projector filter enabled
Low/0 = Projector filter not enabled
Analog input
<SkewPreset#>
This signal has NO effect if automatic video compensation is 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.
Analog input
<VideoInputSelect>
Selects the video source that will be switched to the corresponding video
output.
Valid analog values range from 0d to 4d as follows:
0d = No source
1d = RGB (RGBHV output)
2d = Composite (VIDEO output)
3d = S-Video (S-VIDEO output)
4d = Enable VIDEO and S-VIDEO outputs
A value of 4d will a) Switch a composite source to the VIDEO output and
an S-video source to the S-VIDEO output simultaneously; or b) Switch a
component source to the VIDEO and S-VIDEO outputs.
Out of range values are ignored.
Analog output
<VideoInputSelect_F>
Reports the active video source.
Analog inputs
<R_Skew>
<G_Skew>
<B_Skew>
Sets the skew compensation in nanoseconds for the red, green and blue
twisted pairs. These values can be applied directly or saved into a skew
preset.
Skew compensation adjusts for timing delays between twisted pairs that
can occur over long CAT5 cable lengths. The skew adds delay to the faster
pairs, allowing the video signals to be presented in synchronization.
Valid analog values range from 0d (0ns) to 15d (22.5ns), where 1d = 1.5ns.
Out of range values will clip the skew to the minimum or maximum value.
Analog outputs
<R_Skew_F>
<G_Skew_F>
<B_Skew_F>
Reports the skew compensation at the red, green and blue twisted pair.
Analog input
<Peaking>
Applies peaking at the QM input. This value can be applied directly or
saved into a skew preset.
Peaking compensates for high frequency attenuation that can occur over
cable lengths up to 300 feet.
Valid peaking values range from 0% to 100%.
Analog output
<Peaking_F>
Reports the peaking being applied at the QM input.
