The TK-404KR is designed to allow the user to save time and space by limiting the amount of peripherals needed to operate multiple computers; along that design philosophy, the system itself is small, lightweight, and intended to be mounted on rack within the room of use. Cables are used to connect each of the computers to the KVM switch: three each for every system, one mouse, one keyboard, and one video. While the video port uses a DVI-I connection, the mouse and keyboard are not USB and are 6-pin connections. Resolutions of up to 1600 x 1200 can be transferred through the switch to the single monitor.
Computers connected through the switch can be auto detected and also hot swappable during use. Audio can also be accessed independently of video, an example being playing music from one computer while accessing on a text document on another. Switches between computers can either be done by a designated hotkey on the keyboard, or manually with buttons on the front panel of the TK-404KR. LEDs are used to signify the status of each system: currently being accessed, online, offline. Supported operating systems for Microsoft Windows stop at the XP versions. Although a more recent OS may work, they are not officially supported.
