Chapter 2: Overview
2. Overview
2.1 Introduction
Route digital DVI video from various sources (such as a satellite receiver, DVD
player, and PC) to a high-definition display (such as a TV) with the economical
3 x 1, 4 x 1, or 8 x 1 DVI-D Switch from Black Box.
It features a signal enhancer that helps improve signal quality over a long-distance
transmission from source to screen. Running digital video over DVI cable longer
than 15 feet (1.5 m), you might very well experience signal degradation at the
remote screen. This switch, however, is designed to amplify the DVI video signal
as far as 60 feet (18.2 m).
Plus, it’s easy to install and operate. Connect all your digital video sources (DVD
players, satellite set-top boxes, PCs) to any of the inputs on the switch and con-
nect the output cable to your HD display. Then when you want to switch video
ports, simply press a button on the included remote controller or the switch’s
front panel.
NOTE: Equipped with DVI-I ports. Supports digital video only.
2.2 Features
• Switch on the front panel or from the included IR remote controller.
• Route video from three, four, or eight sources to a common digital display.
• Tested to guarantee resolution up to 1080p without signal degradation.
• Signal enhancer amplifies video as far as 60 feet (18.2 m).
• HDCP 1.1 and DVI 1.0 compliant.
• Ideal for use in conference rooms, classrooms, or corporate theaters.
2.3 What’s Included
Your package should include the following items. If anything is missing
or damaged, contact Black Box Technical Support at 724-746-5500
or [e-mail].
• 3 x 1, 4 x 1, or 8 x 1 DVI-D Switch
• Infrared (IR) remote control
• 5-VDC, 2-A power supply
