The USB-845-BC "MegaCast"™ USB Keyboard or Mouse Multicaster routes the output of a single USB keyboard or mouse, to as many as five PCs or MAC's simultaneously.

At the heart of the USB-845-BC "MegaCast"™ USB Keyboard or Mouse Multicaster is Vetra's advanced, US patented technology , which provides and supports true USB functionality through the Multicaster. The connected keyboard or mouse enumerates correctly and may be "hot-plugged" at any time, and the connected PCs may be powered up and down in any order. This unique architecture of the USB-845-BC "MegaCast"™ USB Keyboard or Mouse Multicaster ensures error free boot up and device driver loading for each connected PC, and allows the Multicaster to operate transparently with
all USB compatible PCs, PC operating systems, and applications.For applications requiring rack mounting, an optional 2U height rack mount tray is available (see Accessories ).

After all connections are made and the PCs are powered up, the front panel power indicator will illuminate indicating that the unit is ready to transmit keyboard or mouse data. Additional LEDs indicate which PCs are powered (PC STATUS). Any data from the connected keyboard or mouse will be routed to USB ports of all powered PCs simultaneously.

All shifted keyboard functions will work properly, however, due to design constraints, keyboard back link commands issued from the PC may not be passed to the connected keyboard. What this means is that if you set the CAPS LOCK button on your keyboard, the keyboard will generate shifted (capital) characters, but the CAPS LOCK indicator LED on the connected keyboard may not be illuminated.
