MTP U R Series • Installation

N
Since 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.
N
Unless 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 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 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.
N
A 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:
N
The 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.
