QuickMedia™ Receiver/Processor Crestron QM-RMCRX-BA

Video Output Control Signals (continued)

SIGNAL TYPE AND NAME DESCRIPTION

Digital input

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

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

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

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.
