When the ServSwitch™ brand of KVM switches was first introduced, there were only two ways to switch: from front-panel push buttons or by sending command sequences from the keyboard. While... more/see it nowthis was more convenient than having a separate keyboard, monitor, and mouse for each CPU, the operator still had to remember key combinations and which server was connected to which port—leading to many cryptic, scribbled notes attached to the switch and to the workstation.
But with the advent of on-screen menus, an operator can use easy-to-read, pop-up menus to identify and select CPUs. It’s even possible to give each CPU a name that makes sense to you—names like “MIS Server,” “Accounting Server,” and so on. collapse
UTP cable is often used with video or KVM extenders to extend the reach of a video signal. It’s popular for this application because it’s lightweight, easy to handle, and... more/see it nowinexpensive. But when you transmit video over long stretches of twisted-pair cable, you sometimes run into a phenomenon called color drift or color split.
Color drift shows up as that annoying colored shadow you occasionally see around objects on a video screen. It sometimes happens with UTP cable because the pairs of wire in the cable are twisted at slightly different rates to reduce crosstalk between pairs. Because of these differences between wire pairs, video signals for different colors often travel different distances before they reach the remote receiver. When one color signal arrives behind the others because its wire is longer, you get that red, green, or blue shadow around the objects on your video screen.
UTP cable varies widely by manufacturer, so before installing video extenders, it’s difficult to determine whether or not you’re going to have a color drift problem. You’re more likely to experience color drift with higher grades (CAT5e or CAT6) of cable, on longer cable runs, and on high-resolution screens.
If you experience color drift, there are several possible solutions. You can use a shorter length of cable, switch from CAT5e or CAT6 cable to CAT5 cable, use a lower screen resolution, or use a video skew compensator.
A video skew compensator removes color drift by delaying some color signals to compensate for differences in wire pairs. collapse

Wizard.NET is a professional enterprise management suite that delivers total IP device control, management, and connectivity. Black Box KVM over IP (KVMoIP) devices provide... more/see it nowthe ability to control large numbers of host computers from remote locations. When controlling larger groups of dispersed computers using numerous KVMoIP devices, the major challenge becomes one of management—retaining active control over a complex mix of devices, host computers, and registered users. Wizard.NET was developed as a common interface to help you remotely manage any number of KVMoIP devices together with all of their connected host computers and the access rights of the users.
Wizard.NET is delivered as a software solution only, and operates as a server application running on a system that can be completely separate from any of the KVMoIP devices?—?it merely requires an IP network or Internet connection. Wizard.NET uses an intuitive HTML user interface, which means that registered users can access and control it remotely using a standard Web browser. Like all Wizard KVMoIP products, Wizard.NET employs high specification security techniques to ensure that only authorized users may gain access.
Wizard.NET has two main modules, the manager and the connector. The manager module is accessible only to managers and administrators. It is where the details about all connected devices, hosts, and users are configured and stored. The connector module can be used by registered users to enable quick access to all of the targets for which they have access rights. Targets may be devices, hosts, or device groups as appropriate.
To ensure maximum security, Wizard.NET does not retain any passwords within its database for the devices that it controls. Instead, a valid password is used once only to gain access to each device during the “acquire” stage, when Wizard.NET establishes a Secure Ticket with the device. In all subsequent accesses to each device, the relevant secure ticket is used to gain access. collapse
