Quad Workstation KVM Splitter, the VIP-884 "MegaMux"

Dual-Head Models Available


The VIP-884 "MegaMux""KVM Splitter / Multiplexer allows up to four workstations, each consisting of a keyboard, PS/2 mouse and one or more monitors, to share local access to one PC. It is compact in design, easy to install and operate, and is available in a variety of standard configurations including Dual Video (2 video outputs on the PC) models. The unique video architecture and scalability of this KVM Splitter / Multiplexer allow it to be easily configured to handle PCs with as many as four video outputs, on a special order basis. The VIP-884 utilizes Vetra's advanced keyboard and mouse emulation technology, which provides error free boot up and mouse driver loading to the connected PC. It is compatible with all popular keyboards and mice including Microsoft IntelliMouse, and operates transparently with all PCs, PC operating systems and applications.


Only one workstation may access the PC at any given time. This prevents unwanted input from other workstations as might occur from accidental keystrokes or a bump to the mouse. Workstation selection has two modes. The default mode utilizes a 5 second time out feature that monitors all connected workstations for keyboard or mouse input. The first workstation to generate keyboard or mouse input "seizes" the PC and becomes the "active station". It remains "active" until no further keyboard or mouse input is detected for a period of 5 seconds, at which time it relinquishes control of the PC and the whole process starts again. The second mode provides a lock and release feature which allows the user of an "active station" to lock out (3 taps on the left Shift key) the other workstations, for uninterrupted input to the PC, and then release control (3 taps on the right Shift key) when finished so the other workstations are available once again to the PC.

When PC control passes from one workstation to another, the intelligence in the MegaMux KVM Splitter / Multiplexer updates any changes to the keyboard status indicators, CAPS, SCROLL, and NUM Lock to the current "active station". The connected monitors are not switched, regardless of which workstation is active, and are on at all times.

A workstations keyboard and/or mouse may be disconnected and re-connected (hot-plugged), or exchanged at any time without having to power down the connected PC. This feature is useful if a connected device fails during a critical application. For applications requiring rack mounting, an optional 2U height rack mount tray is available (see Accessories )
