Step 4 — Receiver DIP Switches

•H sync (H+) and V sync (V+) switches — Set these switches up (On) for positive sync or down (Off) for negative sync.

•Composite Sync, SOG, and Video switches — Set these switches as shown in the table on the right to output the indicated format.

•End Unit switch — Set this switch up if either of the following is true:

• The receiver being configured is the only receiver connected to the transmitter.

•The receiver being configured is the last receiver in a daisy-chained system.

Step 5 — 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 1500RL 15HD A SEQ 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 1500RL 15HD A SEQ product in either of two ways:

A		POWER
		12V
		xA MAX	Rear
Smooth	Ridges		Panel
A	A
		3/16"
		(5 mm)
		Max.	Tie
			Wrap
SECTION A–A			Ridges
Power Supply			Earth
Output Cord			Ground

•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 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.

Step 6 — Peaking and Level

Adjust image sharpness with the Peaking control. Increased peaking compensates for mid- and high-frequency detail loss. The LED lights red when minimum (zero) and maximum peaking is reached.

Adjust image brightness using the Level control. View the image and adjust either control for the best image quality.

Step 7 — Skew Compensation

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.Set the skew delay to zero for red, green, and blue by pressing and holding the Select button in for 3 seconds, using a Tweeker or small screwdriver. 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.Adjust the furthest left video signal by using a Tweeker or screwdriver to press and release the Select button until the LED for the left- shifted color lights.

D.Slowly rotate the Adjust control clockwise until the shifted color is properly aligned.

E.Repeat steps C and D to align the third color if needed.
