8-Port Cat 5 Dual Rail LCD KVM Switch with Daisy-Chain Port. Exclusive LED lighting, developed by ATEN, illuminates the keyboard and touchpad for visibility in low-light conditions. Integrated KVM console with 17- or 19-inch LCD screen featuring LED backlighting in a dual rail design. A single console controls up to 8 computers. Space-saving RJ-45 ports and Cat 5e/6 cabling. KVM adapter cables with automatic signal conversion allow for more flexible connection combinations (PS/2, USB, Sun, and serial) to manage all types of computers. OSD tree structure simplifies searching for and managing computers. Conveniently arranged station and port selection buttons for quick switching to the desired computer. The dual rail housing is slightly shorter than a 1U slot, making it easy to fit into an available slot in a 19-inch rack. Additional console port – manage the computers connected to the LCD KVM switch via an external console (monitor, USB or PS/2 keyboard, and USB or PS/2 mouse). Supports an external USB mouse. Dual rail system – the LCD screen can be extended independently of the keyboard/touchpad module.
