Skew Delay Compensation

CAT 5, 5e, and 6 cable can lead to registration errors between the Red, Green, and Blue video signals. Pair skew can be measured with test equipment or identified by viewing a crosshatch test pattern with a critical eye to determine if either the Red, Green, or Blue video image leads (appears to the left of) the other two video images.

NOTE: Unless the twisted pair cable is changed, the skew adjustment should need to be made only once, during installation.

SEQ Receiver Skew Compensation

The SEQ receiver has built-in skew compensation capabilities.

Adjust the equalization as follows:

1.Zero the skew delay for Red, Green, and Blue as follows:

a.Use a small screwdriver to press and hold the Select button for three seconds. The Red, Green, and Blue LEDs all go out.

b.Release the Select button.

2.Use UTP cable test equipment or examine the displayed video image with a critical eye to determine which video signal — Red, Green, or Blue — is most shifted to the left.

NOTE: A crosshatch test pattern or a black background with vertical white lines is ideal for determining skew.

3.Adjust the leftmost video signal as follows:

NOTE: The SEQ receiver cannot shift the rightmost video image to the left.

a.Use a small screwdriver to press and release the Select button until the LED lights for the left-shifted color — Red, Green, or Blue.

b.Slowly rotate the Delay control clockwise while monitoring the display. Observe that the leftmost color shifts rightward one step at a time. Continue to rotate the control until that color is properly converged.

NOTE: A 2-nanosecond adjustment is very fine. Up to 10 nanoseconds of delay may be necessary before you detect a change in the display.

c.Use a small screwdriver to press the Select button one more time to save the most recent adjustment or allow the 10-second time-out to elapse.

4.If the remaining colors are left shifted, repeat steps 2 and 3.

Non-SEQ Receiver Skew Compensation

Try using the following methods to minimize or eliminate pair skew:

•• Switch to Extron Enhanced Skew-Free AV UTP cable.

•• Add a skew compensation cable equal to the length of pair skew to the output of the receiver.

•• Install an SEQ 100 15HD Skew Equalizer to the video output of the receiver and adjust the skew for the leading video image.
