The USB-884-KM "MegaMux"™ USB
Splitters/Multiplexers allow four workstations, each consisting
of a USB keyboard and mouse, to share
local access to one PC. Access is limited to one workstation at a time, effectively forming an intelligent USB hub.
The USB-884-KM utilizes Vetra's patented, unique TruReflekt™
USB keyboard and mouse enumeration technology. The keyboard and mouse are not just emulated, as in most competitive products, but truly enumerated. This means that all special features that may be present in the keyboard and mouse, are conveyed to the PC, and are available to the user during device operation.
The splitters/multiplexers operate transparently with all PCs, PC operating systems and applications.
On all models only one workstation
may access the PC at any given time, effectively making an intelligent USB hub. This prevents unwanted input
from the other workstations as might occur from accidental keystrokes
or a bump to the mouse. There are two modes to select the active workstation.
The first, default, mode monitors all 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 the station by making 3 taps on the left Shift key. The other workstations are locked out, giving the "active" station uninterrupted input to the PC. Three
taps on the right Shift key will release the "active" station, returning to the default operation mode.
On all models, any changes to the keyboard status indicators, CAPS,
SCROLL, and NUM Lock are shown on the keyboards of all workstations.
USB-884-KM USB splitters/multiplexers are powered by an external power supply, which is supplied with the unit.
For applications requiring
rack mounting, an optional 2U height rack mount tray is available
(see Accessories ).
