The Aten 2L-7D03UD is a KVM cable set for connecting a computer (source) to a KVM switch (console). It enables the transmission of video, USB data, and audio signals over a length of 3 metres. The cable is finished in black and features identical connectors at both ends. The interface to the PC includes a DVI-D (Dual Link) 24+1 plug, a USB Type-A plug, and two 3.5 mm jack plugs (for microphone and speaker). At the other end, for connection to the KVM switch, there is a DVI-D (Dual Link) 24+1 plug, a USB Type-B plug, and also two 3.5 mm jack plugs. The design allows for a direct, cable-based connection without additional adapters or converters.

Applications
This cable is specifically designed for use in IT infrastructures where multiple computers are controlled via a KVM switch. It is typically used in server rooms, data centres, or workstations with multiple systems, where central control via a keyboard, monitor, and mouse is required. The use of DVI-D Dual Link enables the transmission of high-resolution video signals, which is important for professional applications with high demands on image quality.

Functions and Equipment in Detail
The cable simultaneously transmits video, USB peripheral devices (such as keyboard, mouse), and audio signals (microphone and speaker) over a single cable. The DVI-D (Dual Link) interface supports high resolution and is designed for use with graphics cards and monitors that support Dual-Link. The USB connection enables control of input devices via the KVM switch. The two 3.5 mm jack plugs ensure bidirectional audio transmission, allowing both audio playback and microphone input through the cable.

Technology Explained Simply
The term DVI-D (Dual Link) refers to a digital video transmission technology that uses two data channels (links) to enable higher resolutions and refresh rates. This is particularly important for applications requiring high image quality and stable signal transmission. The USB connection uses standard connectors Type A (to PC) and Type B (to switch), ensuring universal compatibility with common KVM switch models. The audio transmission via 3.5 mm jack plugs is a common solution for integrating speakers and microphones into KVM systems.

Compatibility and Accessories
The cable is designed for a range of Aten KVM switch models, including CS1782A, CS1784A, CS1788, CS1642, CS1644, CS1182, CS1184, and CE602. These devices support the combination of DVI-D Dual Link, USB, and audio, enabling full control of connected computers via a shared console. Compatibility with other manufacturers is not explicitly confirmed, but the connection technology (DVI-D, USB, audio) is standardised, so compatibility with similar systems may be possible.

Installation and Mounting
Installation is performed by simply plugging the cable ends into the corresponding interfaces: at the source (PC) into the DVI-D, USB Type-A, and audio connections; at the KVM switch into the DVI-D, USB Type-B, and audio connections. No additional tools or configurations are required. The connection is immediately operational once the plugs are correctly connected.

Operational Advantages
By combining video, USB, and audio in a single cable, the number of required connections is reduced, simplifying installation and reducing cable clutter. The 3-metre length provides sufficient flexibility for typical work environments. The use of DVI-D Dual Link ensures stable, high-resolution video transmission, while the USB and audio connections enable full control of peripheral devices. The cable is designed for use in professional IT environments and supports efficient management of multiple systems via a shared console.
