ATEN CS-521/CS-522 User Manual
The CS-521/CS-522 is a compact two‑port KVM switch that lets a single console control two computers. It includes built‑in custom KVM cables (USB for the CS-522 model, USB + PS/2 for the CS-521) and supports speaker output, LED status indicators, and hot‑key switching.
Installation is straightforward: connect the console’s keyboard, monitor, mouse and optional speakers, attach the integrated cables to each computer, power up, and use hot‑key combinations to toggle control. The manual also covers hardware requirements, front‑panel layout, and troubleshooting tips such as keyboard compatibility and notebook limitations.
