Chapter 2: Overview

2.5 How to Use This Guide

This guide describes the installation and configuration of the DVI-D/-I CATx/Fiber – Extender Series. Although the connection and operation of the system is relatively straightforward, you should consider the following before getting started:

Connection and Compatibility

If you have purchased an Extender Kit, this will contain all the cables required to connect the local unit to your PC or KVM switch. Please see also: 3.1 What‘s Included.

For information about connection and installation, see 3.2 Interconnection Cable Requirements.

DDC information

Normally it is not necessary to make any adjustments to the DVI-D/-I CATx/Fiber- Extender. However, in some circumstances, it may be necessary to redefine the source of DDC information for the CPU. By default, the DVI-D/-I CATx/Fiber KVM-Extender uses its own internal DDC table. If this setting does not satisfy your requirements, the DDC table can either be switched to the locally attached screen or could be downloaded from a remotely located screen and stored in the internal DDC table.

To modify the DDC setup, see 4.0 Service Setup.

Selecting the moment of switching to the next frame

The transmission of screen data is not synchronous to the screen change of the graphics card. Normally, the transmission is terminated during displaying a frame on the screen. If the device switches to the new frame during the displaying period of the old frame (somewhere on the screen), it’s possible, and that you can see horizontal screen breaks in the moment of switching (default). On the other hand, the device must idle, until the actual frame is displayed completely (until VSYNC) -> the number of frames per second transmitted sinks.

To modify the switching behavior, see 4.0 Service Setup.

Selection of color reduction for transfer acceleration

You can select, whether always 24-bit colors (=full color depth) are transmitted or whether the compression algorithm automatically switches between 16- and 24-bit colors to accelerate the data transfer (default). Normally the difference between 24-bit and 16-bit is not recognizable but under some special circumstances, e.g. in photo processing installations, there might be disturbing color aberrations. However, the automatic color switching enhances the frame count transmitted per second; fixed 24-bit color depth gives smooth color grades under all circumstances. Choose the one that’s best for your application.

To modify the color depth, see 4.0 Service Setup.

The Black Box ACS4002A-R2-MM and ACS4011A-R2-SM are part of an advanced series of DVI-D CATx/Fiber KVM extenders. These high-performance extenders bridge the gap between computer systems and remote displays, offering impressive solutions for various industries including broadcasting, digital signage, and corporate environments.

The ACS4002A-R2-MM model uses multi-mode fiber technology, enabling it to transmit video at high resolutions up to 1920x1200 at distances of up to 300 meters. It's designed for seamless integration into existing infrastructures, utilizing standard CAT5e cables in conjunction with fiber optics. This versatility ensures that installations are both efficient and cost-effective, making it ideal for expansive setups.

On the other hand, the ACS4011A-R2-SM variant specializes in single-mode fiber, pushing the transmission range even further. It can deliver high-definition video from a computer to a display up to a remarkable distance of 10 kilometers. This characteristic is particularly beneficial in large-scale operations, where the distance between systems can be considerable.

One standout feature of these KVM extenders is their ability to support DVI-D signals. This ensures immaculate video quality without degradation, which is critical for applications demanding high resolution and color fidelity. Both models also support USB pass-through, facilitating the connection of peripherals such as keyboards and mice. This enhances user experience, allowing for full control of the remote system from a distance.

In terms of installation, the ACS4002A-R2-MM and ACS4011A-R2-SM are designed for user-friendliness. They come with plug-and-play capabilities that simplify setup and minimize downtime. Furthermore, their robust design ensures reliable performance, even in challenging environments, making them suitable for various demanding applications.

The technologies embedded within the ACS4011A-R2-MM and ACS4011A-R2 offer dual power inputs for redundancy, ensuring that the systems remain operational during unexpected outages. This level of reliability is crucial for mission-critical environments where uptime is paramount.

Whether upgrading an existing video system or designing a new one, the Black Box ACS4002A-R2-MM and ACS4011A-R2-SM KVM extenders present a superior solution for high-performance video transmission, combining advanced features, impressive technologies, and unparalleled reliability.
