Your business is growing faster than you expected and four computers simply arent enough to meet your needs. Not a problem! ATENs new eight-port MasterView CS9138 KVM Switch is just the tool you need to help reduce the need for redundant hardware. Eight monitors, mice and keyboards are simply too expensive, bulky and down-right inconvenient for most system administrators. Why bother when you can control all eight, or even up to 512 computers with a single keyboard, monitor and mouse.
