Gain and Peak
The Gain and Peak potentiometers on the CatPro RX Module are used to help compensate for the overall
cable length.
To adjust the gain and peak using the CatPro RX Module:
1.
On the Source PC, open the test image .pdf file that corresponds to the resolution of the Source PC.
2.
Route the source to the destination.
The test image appears on the Destination Monitor (the image will be distorted due to cable length).

3.
If the Destination Monitor's brightness needs to be increased or decreased, turn the Gain
potentiometer until the desired brightness is reached.
4.
If the picture is not sharp enough, turn the Peak potentiometer. (Increasing the peak removes the
graininess.) The image will still be skewed.

If the skew was adjusted previously, restore the default settings before proceeding (adjust skew fully
counterclockwise on R, G, and B in the steps on page 140 and save).
Additional potentiometer fine-tuning may be necessary after adjusting skew.
Skew and Volume
The Adjust knob on the CatPro RX Module can be used to compensate for the skew inherent in the
supported cables types by adjusting the video signal to eliminate the skew. It also adjusts the volume.
A small screwdriver works well for turning and pressing the knob. The knob does not have a mechanical
start or stop point. If the LED blinks when the knob is turned, the setting has reached its minimum or
maximum adjustment point.
