Their website has absolutely nothing on it and I have not been able to google anything either. The unit is a 12 port ADB KVM by the looks of it, I don't see a connector in the picture for power input or anything. Any help would be appreciated. Thanks TZ ------------------ I've got the perfect answer for you. Call black box at ANY time and they'll help you. I have a 4port KVM from them and had some questions about it, but it was Saturday night. Anyway I called their support line, and shortly thereafter that night, a support guy called me! He was helpful and got all my questions answered. I was simply amazed at the topnotch support. If only every company could be like this.
