4 port PS/2 keyboard Multiplier / Multicaster, the VIP-844-BC MegaCast


The VIP-844-BC "MegaCast"™ PS2 Keyboard Multiplier / Multicaster routes the output of a single PS/2 keyboard, to as many as four PCs simultaneously. In addition, the VIP-844-BC MegaCast™ may be cascaded to accommodate as many as 16 PCs. It is idealy suited for applications requiring redundant keyboard input, such as the testing and administration of multiple PCs, and for multiboxing applications for MMORPG's such as World of Warcraft. The VIP-844-BC PS2 Keyboard Multiplier / Multicaster is compact, easy to install, and supports all popular PS/2 keyboards.

The unique architecture of the VIP-844-BC MegaCast™ provides a dedicated microprocessor for each PC. This feature makes it possible to "hot-plug" the keyboard at any time, and power the connected PCs up and down, in any order. At the heart of the MegaCast™ is Vetra's advanced keyboard emulation technology which provides error free boot up and driver loading for each connected PC, and allows the MegaCast™ to operate transparently with
all IBM compatible PCs, PC operating systems, and applications. The VIP-844-BC MegaCast™ PS2 Keyboard Multiplier / Multicaster is powered by the connected PCs so no external power supply is required. For applications requiring rack mounting, an optional 2U height rack mount tray is available (see Accessories ).

All Vetra KVM Products are designed and manufactured in the USA for enterprise mission-critical applications for use around the world and are backed by a Limited 3-year Warranty. For more information on this product or our complete line of KVM solutions, please contact us at


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 data. Any keystroke from the connected keyboard will be routed to PS/2 keyboard ports of all the connected PCs simultaneously.

All shifted keyboard functions will work properly, however, due to design constraints, keyboard back link commands issued from the PC are not 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 will not be illuminated.

Each output from the VIP-844-BC that the keyboard is connected to, can feed the input of another VIP-844-BC. In this manner, a maximum of 16 PCs can receive keyboard data from the connected keyboard.
