earth ground.

• Ground the chassis — Use a connector hex nut (see image B the right). Tie the other end of the wire to an earth ground.

If you have any questions about how to ground a product in a specific application, contact an Extron technical support specialist.

Step 7 — Pre-Peak, Peaking, and Level

•Transmitter Pre-Peak switch — View the image and set the Pre-Peaking switch for the best image quality to correct for long cable runs of the entire system (including all daisy-chained receivers).

•Receiver Peaking control — View the image and adjust the Peaking control for the best image sharpness. Minimum setting (full counterclockwise) is zero peaking.

•Receiver Level control — View the image and adjust the Level control for the best brightness level.

Step 8 — Skew Compensation (SEQ Receivers)

Pair skew can be measured with test equipment or by viewing a crosshatch test pattern. The SEQ receivers have built-in skew compensation capabilities. Adjust the equalization as follows:

A.Zero the skew delay for red, green, and blue by using a small screwdriver to press and hold the Select button for 3 seconds. When the Red, Green, and Blue LEDs all go out, release the Select button.

B.Use UTP cable test equipment or examine the displayed image to determine which video signal — red, green, or blue — is shifted furthest to the right.

C.Select the furthest left video signal by using a small screwdriver to press and release the Select button until the LED for the left-shifted color — Red, Green, or Blue — lights.

D.Slowly rotate the Adjust control clockwise until the selected color is properly converged.

E.If the remaining colors are left-shifted, repeat steps C and D.
