4. Functionality
The K102 cable serves as a unified connection interface between a computer and a KVM switch, or between multiple KVM switches in a daisy-chain configuration. It transmits three essential signal types—video (VGA), keyboard, and USB—through a single bundled cable assembly.

How It Works:
- The VGA connector transmits analog video signals from the computer’s graphics output to the KVM switch’s video input.
- The USB connector provides keyboard and mouse data channels, allowing the KVM switch to emulate or directly control input devices on the connected system.
- When used in a daisy-chain configuration, the cable links the daisy-chain port of one KVM switch to the next, enabling centralized management of multiple KVM units.

Use Cases and Applications:
- Data Centers: For connecting servers to centralized KVM switches, reducing cable clutter and simplifying maintenance.
- IT Administration: Ideal for system administrators managing multiple computers from a single console.
- Industrial Control Rooms: Enables efficient control of multiple systems in manufacturing or process monitoring environments.
- Office and Lab Environments: Suitable for multi-system workstations or test benches requiring quick switching between computers.
- Rack-Mounted Systems: Compact 1.8 m length is optimized for short interconnections within server racks.

Compatibility:
- Compatible with most 8-port KVM switches supporting VGA and USB interfaces.
- Works with standard VGA video outputs and USB keyboard/mouse interfaces on PCs, servers, and workstations.
- Backward compatible with USB 1.1 devices and forward compatible with USB 2.0 ports.
