The CS1788 8-Port USB DVI Dual Link KVM Switch is a multi-purpose appliance that consolidates access and control of up to 8 computers from a single USB keyboard, USB mouse, and dual-monitor (DVI-I and VGA) console. It can be cascaded to three levels – allowing up to 73 CS1788s to control up to 512 computers – all from the original single console, making it ideal for IT applications and management. In addition, the CS1788 features Multi-view functionality, which enables the use of standard USB cables to stack up to four switches for quad-viewing in multiple-monitor installations where each computer is fitted with multiple video cards. It allows you to contrast, analyse and monitor video output in convenient ways, substantially simplifying the working environment. Furthermore, the CS1788 comes with ATEN´s on-screen display (OSD) function, which can access any computer connected to the installation, it also offers OSD configuration back up/restore to save/ back up the OSD settings and restore them as needed.
