The KL1516Ai Dual Rail LCD KVM Switch is a control unit that allows secure access up to 16 computers from a single KVM (keyboard, video, and mouse) console. It consists of an integrated LCD monitor, keyboard, and touchpad in a 1U rack-mountable retractable sliding housing. The LCD and keyboard/touchpad modules slide independently of each other. To maximize space in your data center, the keyboard/touchpad module slides back to " hide away " when not in use, while the thin profile LCD monitor rotates back - flush against the rack - allowing convenient monitoring of computer activity. The KL1516Ai features IP-based connectivity that allows local and remote operators to monitor and access the computers on your installation. Because it uses TCP/IP for its communications protocol, the KL1516Ai can be accessed from any computer on the LAN, WAN, or Internet - whether that computer is located down the hall, down the street, or halfway around the world.
