The Aten CS1794-AT-G is a 4-port KVM switch with integrated USB 2.0 hub and audio transmission, specifically designed for use on desks in home offices, small businesses, and multimedia environments. The device enables control of up to four computers or other HDMI-compatible devices – such as game consoles – via a single console with keyboard, mouse, and monitor. The HDMI interface ensures high-resolution video transmission, achieving a maximum resolution of 1920 x 1200 pixels (WUXGA) or 1080p. The Video DynaSync™ technology stores the EDID (Extended Display Identification Data) of the connected monitor to automatically optimize the display resolution and ensure the best possible image quality.

Applications

The CS1794 is suitable for work environments where multiple computers or HDMI sources are operated via a shared input console. Typical use cases include offices with multiple workstations, multimedia setups, or home entertainment systems where a single user wants to switch between different devices. The integrated digital audio transmission supports high-quality audio formats such as Dolby True HD and DTS HD Master Audio, making it suitable for applications with high audio quality requirements.

Functions and Features in Detail

The device features four HDMI video inputs and four USB Type-B connectors for connecting the attached computers. At the console, there are two USB Type-A connectors for keyboard and mouse, one HDMI output, and two 3.5 mm audio jacks (one for headphones, one for microphone). The front buttons allow independent switching between connected computers, while hotkeys on the keyboard enable quick control without physical interaction. The automatic detection of powered-on devices ensures that the switch automatically switches to the next powered-on device when one is turned off.

Technology Explained Simply

The CS1794 operates with USB 2.0 specification (data rate up to 480 Mb/s) and is fully compatible with USB 2.0 standards. Power supply is provided via an external power adapter with an input voltage of 5.3 V. In standard operation, the power consumption is 3.62 W. The HDMI interface is HDCP-compatible, enabling the transmission of encrypted content (e.g., from Blu-ray players). The Video DynaSync™ technology ensures that the monitor’s resolution is optimally adjusted to the capabilities of the connected computer, without requiring manual settings.

Compatibility and Accessories

The switch supports multiple operating systems, including Windows, Linux, and macOS. Keyboard emulation ensures error-free booting, even for systems requiring special keyboard codes. Mouse port emulation supports most mouse drivers and multifunction mice. As accessories, a KVM cable set is included in the delivery, enabling the connection between the console and the connected computers. Additionally, a cable for firmware updating is provided to bring the device to the latest software versions.

Mounting and Installation

The device is designed as a desktop unit and is placed directly on the desk. Installation is performed using the included KVM cables, which are connected to the respective ports on the computers and the console. Power supply is provided via the external power adapter, which is plugged into a power outlet. Operation is performed via the front buttons or hotkeys on the keyboard. The interfaces are clearly labeled to enable easy and error-free cabling.

Operational Advantages

The CS1794 offers a space-saving and compact solution for controlling multiple devices. The integrated USB hub function allows the use of two additional USB devices (e.g., printer, flash drive) via the console. The independent switching between KVM, USB peripherals, and audio via front buttons and hotkeys increases efficiency. The automatic port switching (scan mode) enables monitoring of all connected devices. The firmware is upgradable, ensuring long-term compatibility and security of the device. The housing is made of metal and plastic and is finished in black, providing a professional appearance. The operating temperature ranges from 0 to 50 °C, and the relative humidity during operation is 0 to 80 %. The device is designed for indoor use and is not intended for outdoor applications.

Delivery Contents

The delivery includes the CS1794-AT-G KVM switch, four KVM cables (2L-7D02UH), a cable for firmware updating, a power supply (0AD8-1605-24M1), a user manual, and a quick installation guide. A USB-PS/2 adapter is also included in the delivery to ensure compatibility with older devices.
