The Aten CS1784A is a 4-port KVM switch with integrated USB 2.0 hub and audio support, specifically designed for use in office environments or technical workstations with multiple computers. The device enables control of up to four computers via a shared console consisting of a keyboard, mouse, and monitor, with signals transmitted via DVI-I and USB connections. The unit is designed as a desktop device, featuring a metallic housing in black, which is robust and compact. Dimensions are 270 mm (width) × 88 mm (depth) × 55.5 mm (height), allowing it to integrate well into existing workspaces.

Applications

The CS1784A is suitable for workstations where multiple computers must be operated via a shared input console, for example in IT departments, server rooms, call centers, or technical service providers. The support for 2.1 surround sound systems also makes it suitable for applications requiring audio, such as using IP phones, headsets, or speaker systems. Compatibility with various operating systems including Windows, Linux, Mac, and Sun extends its application across different IT environments.

Functions and Equipment in Detail

The device features four KVM ports, each with a DVI-I video connection, a USB Type-B port for keyboard and mouse, and two audio connections (line-out and microphone) per computer. The console provides a DVI-I connection, two USB Type-A ports, and two audio connections (line-out and microphone). The integrated USB 2.0 hub with two Type-A ports allows connection of additional USB peripherals such as printers or flash drives directly to the switch. Port selection is performed via front buttons, hotkeys, or mouse click, making operation flexible and user-friendly. LED indicators show the selected port and USB link status.

Technology Explained Simply

The CS1784A supports a maximum resolution of 2560 x 1600 pixels at 60 Hz via DVI-Dual-Link connections, suitable for high-resolution monitors. Video transmission occurs via DVI-I connectors, which can transmit both digital and analog signals. Power supply is via an external power adapter with an input voltage of 5.3 V. Power consumption in standard operation is 5.91 W. Scanning intervals can be set between 1 and 99 seconds, allowing adjustment of automatic port switching for powered-off computers. The firmware is upgradable, enabling maintenance and adaptation to new requirements.

Compatibility and Accessories

The switch is equipped with DVI-Dual-Link technology and thus supports high-resolution monitors. Audio support includes 2.1 surround sound, with two line-out and two microphone connections available per computer. Compatible accessories include KVM cable sets such as the 2L-7D02UD (DVI-D Dual Link with USB connectors) or the KVM cable 2L-7D03UD (3 m, DVI-D, USB, audio). These cables enable connection of computers to the console. Use of DVI-to-VGA adapter cables is also possible, provided the devices support it.

Installation and Mounting

Installation involves connecting the four computers to the respective KVM ports (DVI-I, USB Type B, audio) and the console to the front connections (DVI-I, USB Type A, audio). The included KVM cable sets (4 x 1.8 m) simplify cabling. Power supply is via the external power adapter, which is connected to a power outlet. Operation is performed via front buttons, hotkeys, or mouse, with LED indicators showing the status. Firmware can be updated via the user manual.

Advantages in Operation

The CS1784A provides centralized control of four computers via a single console, enabling more efficient use of workspaces. The integrated USB hub function allows use of additional devices without extra connections. Support for 2.1 surround sound and the ability to select ports via mouse or hotkeys enhance user-friendliness. Automatic detection of powered-on computers and Video DynaSync™ technology ensure stable display during restarts and port switching. Compatibility with various operating systems and firmware updates increase long-term usability and adaptability of the device.

Scope of Delivery

The scope of delivery includes the CS1784A KVMP™ switch, four KVM cables (2L-7D02UD, DVI-D Dual Link with USB connectors), a power supply (0AD6-1605-24EG), and a user manual. A quick installation guide is also included. The cables are each 1.8 m long and enable connection of computers to the console.
