Black Box BLACK BOX ServSwitch Brand KVM Extender, ACS251A-R2

SERVSWITCH™ BRAND FIBER KVM EXTENDER II AND II-SM

The brightness and contrast of the video signal are adjusted automatically before digitizing the signal. This ensures the best possible video quality without requiring configuration or adjustment by the user.

When the local unit detects that the CPU has switched to a different resolution, refresh rate, etc., it will adjust all digitizing parameters automatically. Only a few seconds later, you will again have a sharp, crisp, and colorful image without having to move any switches or turn any dials. The local unit checks all video parameters continuously, so video quality is maximized at all times.

After the local unit digitizes the video, it transmits the digital data across the fiber as a serial stream. Inside the remote unit, the signal is converted back into the original analog values, which it outputs from its “Video” connector. The resolution of the output signal is always the same as that of the original input, but its vertical refresh rate is kept constant (by dropping or repeating frames). No matter what their input refresh rate is:

•DOS-mode resolutions will be output at a refresh rate of 85 Hz.

•Non-DOS-mode resolutions up to 1152 x 864 will be output at a refresh rate of 75 Hz.

•1280 x 1024 and 1600 x 1200 resolution will be output at a refresh rate of 60 Hz.

Make sure that the remote monitor can support your chosen resolution at the corresponding rate. If it doesn’t, the display will look bad or be totally blank.

The remote unit will always output separate horizontal and vertical sync from its “Video” connector on the standard VGA Hsync and Vsync pins (HD15 pins 13 and 14). If you need to connect a remote monitor that uses some other type of sync and/or separate BNC connectors rather than an HD15 VGA connector, call Black Box Technical Support for assistance.

The local unit will support DDC (display data channel) and provide information to the local workstation about its video capabilities. Modern workstations will evaluate this information and set up their graphics output according to the supported resolutions of the extender.

3.2 Mouse Compatibility

The extender supports all common PS/2 style mice and pointing devices including two-button mice, three-button mice, wheel mice such as the Microsoft® IntelliMouse®, trackballs, etc.

BLACK BOX ServSwitch Brand KVM Extender, ACS251A-R2, ACS250A-R2 specifications

The Black Box ACS250A-R2 and ACS251A-R2, part of the renowned Black Box ServSwitch brand, are sophisticated KVM (Keyboard, Video, Mouse) extenders designed to enhance the connectivity and management of computers in various settings. These devices enable users to control multiple computers from a distance, making them essential for data centers, IT environments, and any operation requiring high efficiency and technology integration.

One of the main features of the ACS250A-R2 and ACS251A-R2 is their ability to extend video signals up to 150 meters (approximately 500 feet) over a single Cat5e or Cat6 cable, which reduces the clutter of multiple cables while ensuring high-quality video output. This capability allows users to position their computers in secure or controlled environments while maintaining access from a remote location. This not only enhances security but also contributes to better thermal management and reduced noise levels in the workspace.

The ACS250A-R2 supports a resolution of up to 1920 x 1200 at 60 Hz, ensuring crystal-clear visuals whether for intricate graphics applications or standard desktop activities. In contrast, the ACS251A-R2 can achieve even higher resolutions, making it suitable for high-definition applications. Both models include plug-and-play functionality, allowing for easy installation without the need for additional software or drivers.

In terms of durability and performance, both models are equipped with advanced technologies such as video compression algorithms to reduce latency and improve signal integrity, ensuring that users experience seamless operation. Additionally, they are designed to be robust and reliable, making them ideal for mission-critical applications where downtime can lead to significant losses.

The KVM extenders also support USB 2.0 peripherals, allowing users to connect various devices, including printers and flash drives, enhancing the versatility of their system. With support for multiple operating systems, these extenders are an excellent choice for diverse IT environments, compatible with Windows, Mac, and Linux systems alike.

Overall, the Black Box ACS250A-R2 and ACS251A-R2 KVM extenders encapsulate a blend of advanced features, reliability, and performance efficiency. They serve as powerful solutions for extending KVM capabilities, making them indispensable tools in modern IT infrastructure management.
