MTP SW6 • Setup Guide

REMOTE

MONO AUDIO

This card provides quick start instructions for an experienced installer to set up and operate the MTP SW6 switcher.

Installation

Step 1 — Mounting

Turn off or disconnect all equipment power sources and mount the MTP switcher as required.

Step 2 — TP Inputs from the Transmitters

Terminate up to six TP cables as shown at right. Connect them between MTP transmitters and the Input connectors (both ends need to match).

Step 3 — RS-232 Insert Connector

For bidirectional RS-232 data that is routed from a common source to the TP output regardless of the selected input, plug a serial device into the RS-232 Insert connector.

NOTES:

• For the RS-232 insert to be available on the TP output, it must be enabled by issuing

the E1*1Lrpt} SIS command to the switcher (see the MTP SW6 User Manual).

• When the RS-232 insert is enabled, any content on the audio/RS-232 wire pair for the

TP input tied to the output is disabled.

Step 4 — TP Output to the Receiver

Terminate a TP cable as shown for step 2. Connect it between the Output connector and receiver that is compatible with the transmitters.

NOTE: The input and all outputs should all be terminated using the same standard on both

ends of the cables.

Step 5 — Connect a Local Audio Device

Connect an audio device to the Mono Audio connector. Wire the connectors as shown at right.

ATTENTION: For unbalanced audio output, connect the sleeves to the ground contact. DO

NOT connect the sleeves to the negative (-) contacts.

Step 6 — Remote Connector (Optional)

Connect an RS-232 device OR a contact closure device, such as a KP 6 Keypad Remote Control.

IMPORTANT:

Go to www.extron.com for the complete

user guide, installation instructions, and

specifications before connecting the

product to the power source.

NOTES:

• For RS-232 control, use a cable with ONLY pins 2, 3, and 5 connected.

• For contact closure control, use a cable with pins 2 and 3 NOT connected.

RS-232 communications protocols:

• 9600 baud • 8 data bits

• 1 stop bit, no parity • no ow control

For contact closure control, short the pin for the desired input to pin 5 to select that device. To force an input to be always selected, leave the short in place.

NOTES:

• For contact closure control, auto switch mode must be off.

• Contact closure control overrides front panel input selections.

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

SECTION A–A

Power Supply

Output Cord

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 specic application, contact an Extron technical support specialist.

3/16" (5 mm) Max.

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

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 rmware version 1.02 or newer. Older rmware 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 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

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.
