Extron electronic MTP 15HD RS Power, Grounding guidelines, Pre-Peak, Peaking, and Level

MTP 15HD RS Series • Setup Guide

Step 6 — Power

Wire the 2-pole captive screw connectors for the included external 12 VDC power supplies (see image A on the right). Plug them into all units.

Grounding guidelines

Extron MTP 15HD RS products can be adversely affected by electrostatic discharge (ESD) if they are not grounded correctly.

To prevent malfunctions or product damage, an experienced installer can correctly ground an Extron MTP 15HD RS product in either of two ways:

•Ground the power input port — Insert one end of the grounding wire to the negative or ground

pin on the power input connector (see image A on the right). Tie the other end of the wire to an earth ground.

•Ground the chassis — Use a connector hex nut as shown in image B on 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.

•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. 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.
