RGBHV+Stereo to CatPro Input/Output Boards
Skew and Volume (continued)
The CatPro RX Module ships with factory-defined default settings of "no skew delay" for the skew on
R, G, and B and for "unity gain" on volume. Once the adjustment process has been successfully
completed and saved, the new settings replace the factory settings. The system will restore the new
settings whenever power is cycled. If necessary, restore the video factory default by adjusting the R, G,
and B fully counterclockwise and restore unity gain by adjusting the audio six clicks left from "full on"
(which is blinking); press the Adjust knob to save.
To abort the adjustment procedure at any time:
1.
Hold the Adjust knob down until the LED turns amber. Release the knob, the LED blinks 3 times
and the CatPro RX Module reverts to its previous settings.
Cycling power on the CatPro RX Module during the adjustment procedure will have the same effect.
Individual settings are not stored in memory until all adjustments (Steps 2 through 10 below) have been
made.
To adjust the skew and volume using the CatPro RX Module:
1. If the gain and peak have not already been adjusted, complete the steps on page 139.
2. Press the Adjust knob.
The LED turns red; the module is placed in Red Skew Adjust mode.
3. Turn the Adjust knob clockwise or counterclockwise until the red color bars align as closely as
possible with the green color bars.
4. Press the Adjust knob.
The LED turns green; the module is placed in Green Skew Adjust mode.
5. Turn the Adjust knob clockwise or counterclockwise, if necessary, to align the green color bars with
the red color bars.
6.
Press the Adjust knob.
The LED turns blue; the module is placed in Blue Skew Adjust mode.
7.
Turn the Adjust knob clockwise or counterclockwise until the blue color bars align with the red and
green color bars.
