Chapter 2: Overview

2. Overview

2.1 Introduction

The DVI-D Matrix Switch is a pure digital crosspoint switch for digital DVI video signals. It simultaneously connects up to eight DVI
sources to up to eight display devices. For each video source, you can either use a “point-to-point” mode (where you connect
exactly one source to exactly one display device), or a “point-to-multipoint” configuration, where the video signal of one input is
distributed to several display devices.

Four models are available:

• 4 x 4 DVI-D Matrix Switch (XPT-DVI4X4)

• 4 x 8 DVI-D Matrix Switch (XPT-DVI4X8)

• 8 x 4 DVI-D Matrix Switch (XPT-DVI8X4)

• 8 x 8 DVI-D Matrix Switch (XPT-DVI8X8)

You can operate the Matrix Switch in four ways:

1. manually using the front-panel switches (buttons)

2. remotely using RS-232 control

3. remotely using the built-in Web server (and your preferred Internet browser)

4. remotely using a Telnet console

The Matrix Switch has a blue LED display on the front faceplate. It normally shows the actual switching state (the current connec­tions between the inputs and outputs). When operated remotely using the Web interface, the current switching state of the
matrix displays graphically. With console control (RS-232 or Telnet), you can query the switching state using a command language.

When changing DVI connections between video sources and display devices, not only must you switch the video connections/
information, but you must also properly handle the EDID information (which is mandatory in the DVI standards). The Matrix
Switch manages this automatically, according to your setup configuration.

2.2 What‘s Included

• (1) DVI-D Matrix Switch

• (1) 6.4-ft. (2-m) IEC-320 power cord

• (1) DB9 F-to-DB9 M RS-232 serial cable, straight-pinned

• (2) 19-inch mounting brackets, one with additional center cutout to support ventilation. (This bag will also have eight black

M4x5 mm screws.)

• (4) black rubber stickers (used as unit stands in desktop configuration)

• This user’s manual on CD-ROM

3. Setup and Cabling

3.1 Operation Location Requirements

The Matrix Switch has 40° Ingress Protection (IP) against dust and humidity.

Choose a mounting or operation location where no danger of fluids entering exists. Make sure that the environment falls within
the specified temperature and humidity ranges (see Chapter 1: Specifications for details).

3.2 Setup and Mounting

You can operate the Matrix Switch on a shelf or tabletop. Attach the four rubber feet (included) to each corner on the bottom of
the unit.

Or, you can mount the Matrix Switch in a 19-inch rack, using the brackets supplied. Bracket-mounting is simple. The only tool you
need is a screwdriver (Phillips size 2). Follow these steps:

1. Start on the left-hand side of the unit (the front is the side with the buttons) and unscrew the two front and the two middle
screws completely. Take the bracket that has a center cutout and attach it to the left-hand side of switch, using the longer
M4x5 mm screws contained in the bracket’s bag. Make sure that the switch chassis’ ventilation cutout is not blocked signifi­cantly by the newly attached bracket.

2. Repeat Step 1 on the right-hand side, using the remaining bracket.

NOTE: When installing the switch on a desktop or in a rack, make sure that nothing will cover the ventilation cutouts on the left-

hand side of the unit.

3.3 Electrical Connections

3.3.1 Connecting the Power

1. Attach the power supply cord to the switch’s IEC-320 connector, which is located on the back of the unit. Now plug the power
plug into a wall outlet.

2. The Matrix Switch has no main power switch, so it will immediately start operation after attaching the unit to a powered wall
outlet.

3. After 10 to 15 seconds, the switch will boot and be ready for operation.

4. The power button’s blue LED should be permanently on when the switch is powered on and active. If the main power fails and
then returns, the switch will return to the active state.

5. To turn off the Matrix Switch, unplug the power cable from the outlet.

CAUTION: Never expose any cables to mechanical stress such as bending or pulling. This can damage cables and impact security.

3.3.2 Attaching DVI Video Sources

The next step in setup procedure is attaching video sources.

1. To avoid damaging your Matrix Switch and your existing video sources, power off ALL units before connecting any compo­nents. Power off all video sources, too.

2. Connect your DVI video sources to the Matrix Switch, using your DVI-D-video cables (part number EVNDVI02, not included),
one after another. All Matrix Switch inputs of XPT-DVInxn will be labeled with “Input 1” to “Input 8.” You can use any input
you want for a specific source: all inputs are electrically identical.

3. Make a note of all input connections, so that you know which source goes to which input number.

4. You can use any DVI-D cable. However, with high-quality cable you can place your video source up to 112 feet (35 m) away
from the Matrix Switch. Each input has a signal equalizer that refreshes the signal to standard levels.
