Model AC1031A-2 and AC1031-4

1. Introduction

1.1 General

The Black Box Model AC1031A-2 and Model AC1031-4 Splitters

allow routing of a single DVI equipped device (such as PC) to multiple

DVI displays (such as plasma or LCD screens). The Splitters support

single-link, DVI-I (integrated Analog and/or Digital) video signals at

resolutions of up to 1600x1200. The DVI Splitters feature front panel

LED indicator for power on state, plus they can be used to extend the

DVI output to 10 meters (33 ft). A DVI-I input cable is included with

the unit.

1.2 Features

•Clear & sharp image at resolution up to 1600x1200 (including

1080i).

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

allowing you to connect a DVI-I equipped PC to monitors that

have DVI-I or legacy monitors with VGA inputs only (In this

case HD15 to DVI cableor adapter will be necessary)

•Can be cascaded (2-levels deep) for more outputs

•Installs in minutes

•Compliant with the specification of DVI 1.0

•Includes high quality DVI-I input cable

•Includes Universal (110-220 Vac) Power supply

DVI Splitter

2. Installation

1. Your package includes the Splitter box, a power supply, an input

cable, and this Manual. You may need to purchase additional long

DVI cables for connection your monitors. Black Box sells high

quality DVI cables and adapters at various lengths.

2. Make sure the PC, the Splitter, and the monitors are all turned off

3. Plug the monitor’s cables into the DVI OUT ports of the Splitter

(Note that at least one monitor needs to be connected to the output

A of the Splitter)

4. Plug a male-to-male extension cable from PC’s DVI port to the

Splitter

(Note that a DVI-I input cable is provided with the Splitter.

Referring to figure 3, the DVI-I cable has the analog pins

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

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

output connectors with all the pin sockets, in most cases you can

use the supplied cable to make the connection to your video

source. However, if your video source is purely digital DVI-D,

then the connector may not have the sockets for the additional

analog pins in which case you will not be able to use the supplied

cable as it cannot plug in to your PC’s output and you need to

purchase a DVI-D cable that does not have the extra analog pins.

The DVI-D cable can plug to the Splitter, it just does not have the

extra analog pins Furthermore, it does not make any difference if

the cable is Single or Dual Link. The Splitter is a Single-Link unit

but you can physically plug either a Dual-Link or a Single Link

cable into it)

5. Plug the supplied power adapter to the unit (The green LED on the

front panel turns on)

6. Turn on the monitors.

7. Turn on the PC.

2.1 Cascade Operation

For more outputs you can connect output #1 of the Splitter to the input

of a Slave Splitter. It is recommended to keep cascading to only 2-

levels deep.

3. Troubleshooting

3.1 Problem Solving FAQ

1. What are the Cable Length Limitations?

The splitter can accept up to 5 meters of cable on its input and 10

meters on its output for a total of 15 meters (50 feet total). At long

distances if you start to experience video degradation, you should

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 Splitter 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 splitters do 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 Splitter

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!.
