Model AC1032A-2 and AC1032-4

1. Introduction

1.1 General

The Black Box Model AC1032A-2 and Model AC1032-4 DVI

Switches allow routing of multiple DVI equipped devices (such as

PC’s) to a single DVI display (such as plasma or LCD screen). The

switchers support single-link, DVI-I (integrated Analog and/or Digital)

video signals at resolutions of up to 1280x1024. The DVI Switches

feature front panel switches and indicators for easy operation, plus they

have intelligence to switch to active video input when an input is

unplugged or there is no video present.

1.2 Features

•Clear & sharp image at resolution up to 1280x1024 (including

1080i).

•Supports both digital and analog DVI signals (DVI-I),

allowing you to connect or switch between a DVI equipped PC

and a VGA equipped one (In this case HD15 to DVI cable will

be necessary, and your DVI monitor should be able to support

DVI-I signal)

•Hot pluggable

•Auto skips over the powered off input (no video) and/or

unplugged cable

•Supports the DDC2 standard for all input ports

•Includes Universal (110-220 Vac) Power supply

2. Installation

1. Your package includes the Switcher box, a power supply and this

Manual. You need to purchase input cables for connection to your

video sources. Black Box sells high quality DVI cables and

adapters at various lengths.

2. Make sure the PCs , the switch, and the monitor are all turned off

3. Plug the monitor's cable into the DVI OUT port of the Switch

4. Plug male-to-male extension cables from PCs DVI ports to the

Switch

(A note about cables:ADVI-I cable has the analog pins

surrounding the ground blade. Since the Switch is DVI-I, its

connectors have all the sockets, and since most PCs have DVI-I

output connectors with all the pin sockets,you can use either a

DVI-D or a DVI-I cable to connect to your video source. However,

a DVI-D cable does not bring in the analog signals to the switch

and hence you will not be able to use an analog monitor on the

output.Furthermore, it does not make any difference if the cable is

Single or Dual Link. The Switch is Single-Link and you can

physically plug either a Dual or a Single Link cable into it)

5. Plug the supplied power adapter to the unit

6. Turn on the monitor first. All red LEDs will flash back and forth

(telling you that the unit is searching for video on the inputs).

7. Turn on the PCs. The green LEDs turn on (telling you that the unit

sees a connection and valid signal on the inputs).

3. Operation

The LED’s indicate which input is selected and which inputs are

present. Simply press the switch next to the LEDs on any of the inputs

that have their green LEDs lit to select that input.

Note that you cannot select an input that is not preset or has no video

(the switch will not allow you). Furthermore, if you select an input that

has video and later that input is disconnected (or the Pc to which it was

plugged in is turned off), then the unit will select the next valid input.

4. Troubleshooting

4.1 Problem Solving FAQ

1. What are the Cable Length Limitations?

The switcher cannot be used as an extender. Therefore it is best to

plug the output of the switch directly to the display device and use

input cables that are 5 meters (16 ft) maximum. In other words, try

to keep the total length of cablesfrom the video source to the box

and from the box to the monitor should not exceed 16 feet. At

longer distances you may experience video degradation. If you

cannot use shorter cables, try to turn the refresh rate and/or

resolution of the video signal lower.

2. What about HDCP (High-bandwidth Digital Content

Protection) in home entertainment systems?

The switcher is designed to primarily work with PC’s with DVI outputs.

If you want to use it in a Home-Theatre setup with DVI connections, it

may or may not work. The switchersdo not provide compatibility with

HDCP encoded video sources. For example if you have a DVD player

with DVI output, depending on the brand, or the DVD, it could enforce

HDCP content protection. If HDCP is not enforced, then the switcher

will function well, however if HDCP is enforced, then at best the DVD

player will output at 480p mode, and at worst it will not output any

video on its DVI output instead a message will be displayed to use

another output!.
