NSince this product differs from the standard MTP receiver by its ability to auto detect the video format received, based on the video signal quality, it requires a reasonable adjusted signal for both level and peaking. There is some margin for over peaking, but if too much over peaking occurs the signal may not be recognized due to signal loss.
Skew Delay Compensation
CAT 5/5e/6 TP 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.
NUnless the TP cable is changed, the skew adjustment should only need to be made once, during installation.
SEQ receiver skew compensation
The SEQ receivers have
1. Zero the skew delay for red, green, and blue as follows:
a. Use a Tweeker or other small screwdriver to press and hold the Select button for 3 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 shifted furthest to the right.
NA crosshatch test pattern or a black background with vertical white lines is ideal for determining skew.
3. Adjust the furthest left video signal as follows:
NThe SEQ receiver cannot shift the furthest right video image to the left.
a. Use a Tweeker or other small screwdriver to press and release the Select button until the LED for the left- shifted color; Red, Green, or Blue; lights.
b. Slowly rotate the Adjust control clockwise while monitoring the display. Continue to rotate the control until that color is properly converged.
