Grounding guidelines
An Extron MTP SW6 can be adversely affected by electrostatic discharge (ESD) if it is not grounded
correctly.
To prevent malfunctions or product damage, an experienced installer can correctly ground an
Extron MTP SW6 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 (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 8 — Pre-Peak, Peaking, and Level
• 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).
• Peaking control — View the image and adjust the Peaking control for the best image sharpness. Minimum RGB
PEAKING LEVEL setting (full counterclockwise) is zero peaking.
• Level control — View the image and adjust the Level control for the best brightness level.
NOTES:
• The simplest and surest way to set the input level and peaking is to use an optional MTP signal generator and the Execute auto-
calibration SIS command (see the MTP SW6 User’s Manual for details).
• The switcher must be running firmware version 1.02 or newer. Older firmware versions appear to respond correctly, but do not adjust
the level and peaking values correctly.
Step 9 — Skew Compensation
Pair skew can be measured with test equipment or by viewing a crosshatch test pattern. Adjust the equalization for the DELAY

SELECT
selected input as follows:
1. Zero the skew delay for red, green, and blue by using a Tweeker or mall 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.
2. 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.
3. Select the furthest left video signal by using a Tweeker to press and release the Select button until the LED for the left-shifted color — Red,
Green, or Blue — lights.
4. Slowly rotate the Adjust control clockwise until the selected color is properly converged.
5. If the remaining colors are left shifted, repeat steps 3 and 4.
6. Repeat steps 1 through 5 for each input.
Operation
Select an input — Press and release the desired input button.
Toggle auto switch mode on and off —
1. Press and hold the Mode (Input 1) button.
2. Press and release the Auto or Normal button.
3. Release the Mode button.
