Aten CS84U KVM switch VGA PS/2+USB 4 ports content_copy

The Aten CS84U is a 4-port KVM switch for desktop use, enabling control of four computers from a single KVM console. The console consists of a keyboard, a mouse, and a VGA monitor, with input devices connectable via both USB and PS/2 interfaces. The device supports Aten's Video DynaSync™ technology, which prevents display issues during computer booting and optimizes resolution when switching between ports. Installation requires no software configuration or installation routines, thereby eliminating compatibility issues from the outset.

Applications

The CS84U is suitable for work environments where multiple computers need to be operated from a single location, such as IT departments, server rooms, or workstation maintenance. It is particularly suited for environments with mixed platforms, as it supports Windows, Linux, Mac, and Sun systems. Support for gaming keyboards and multilingual keyboard layouts (English, Japanese, French) extends its application in international or specialized work environments.

Functions and Features in Detail

Computer selection is performed via front-mounted push buttons, hotkey combinations, or through the USB mouse. The console features a USB Type-A port and a 6-pin Mini-DIN port for keyboard and mouse, complemented by a VGA port (HDB-15) for the monitor. Each of the four computer connections (KVM ports) is equipped with an SPHD-18 connector (yellow). LED indicators show the online status (orange) and the selected port (green). The firmware is upgradable, allowing adaptation to future requirements.

Technology Explained Simply

The CS84U supports a maximum resolution of 2048 x 1536 pixels (QXGA) at a video bandwidth of 60 Hz, ensuring clear and sharp image display. DDC2B support enables automatic adjustment of screen resolution to the respective graphics card. Video DynaSync™ technology ensures no image disturbances occur when switching between computers, especially during device restarts. Keyboard emulation ensures error-free booting, even on systems requiring special keyboard commands. Mouse port emulation and bypass function support most mouse drivers and multifunction mice.

Compatibility and Accessories

The KVM switch is designed for computers with VGA graphics and supports both PS/2 and USB input devices. Compatible accessories include KVM cables such as the 2L-5205U (5 m), 2L-5202U (1.8 m), 2L-5302UP (1.8 m), and 2L-5203U (3 m). These cables enable connections between the switch and the connected computers. The cables are available in various lengths to accommodate different distances in the work environment.

Mounting and Installation

The device is designed as a desktop unit and is not rack-mounted. Installation is performed by directly connecting the cables to the respective ports. No external power supply is required; power is supplied via a DC 5 V connection. Dimensions are 210 mm (width) × 88 mm (depth) × 55.5 mm (height), and the weight is 1.51 kg. Operating temperature ranges from 0 to 50 °C, and relative humidity during operation is 0 to 80 %.

Operational Advantages

The CS84U offers fast and easy operation without software configuration. Direct interception of keyboard inputs enables use across different platforms. Automatic port switching at intervals of 3, 5, 10, or 20 seconds (default: 5 seconds) facilitates monitoring of connected computers. Power consumption in standard operation is 0.45 W, ensuring energy-efficient use. The housing is made of metal and is available in black and gray, providing a robust and professional appearance.

Scope of Delivery

The scope of delivery includes the CS84U KVM switch, two KVM cables 2L-5301UP, two KVM cables 2L-5302UP, and a user manual. The cables are intended for connecting the console to the computers. The quick installation guide and operating instructions are included in the delivery to support setup. Batteries are not included in the delivery scope.
