FEA TURES

•AT➝PS/2 Mouse GHOST Emulator
connects a PC/AT to a KVM switch
or extender with PS/2 mouse ports.

• Keyboard and Mouse GHOST Emulator
plugs into a PC in lieu of a keyboard,
so the PC boots but can’t be used
without authorization.

• Both GHOST Emulators plug into a PC
in lieu of a mouse.

• AC244A converts PS/2 mouse data
to serial.

• AC245A has a pass-through port for
the keyboard.

OVERVIEW

These days it seems you can never have too much data
security. Hackers aside, there are any number of well­intentioned people who can, just by typing at the keyboard,
accidentally compromise your unattended IBM

®

PC type
computer systems. It’d help if you could lock up these
computers’ keyboards and mice, wouldn’t it? But how can
you, when PCs don’t boot without a keyboard attached?

The Keyboard and Mouse GHOST Emulator (AC245A)
helps keep unauthorized users from poking around on your
PCs. When, instead of a keyboard, you attach this emulator to
a computer, the emulator sends the booting PC the responses
that a keyboard would. So the PC boots and operates
normally, without an attached keyboard to attract the itchy
fingers of the uninvited.

The AT➝PS/2 Mouse GHOST Emulator (AC244A)and the
Keyboard and Mouse GHOST Emulator (AC245A) do the same
thing with the PC’s mouse port (which must be serial for the
AT➝PS/2 Mouse GHOST Emulator, PS/2 type for the Keyboard
and Mouse GHOST Emulator). A GHOST Emulator attached
to the mouse port sends mouse responses to the booting PC,
so that the PC boots properly, loads its mouse driver, etc.,
without an attached mouse.

Both of these emulators are easy to install, include cables,
and don’t require user intervention once they are hooked up.
They’re all powered by a PC interface rather than an external
power supply: The AT➝PS/2 Mouse GHOST Emulator is
powered by the serial mouse interface; the Keyboard and
Mouse GHOST Emulator is powered by the keyboard
interface.

The AT➝PS/2 Mouse GHOST Emulator has a passthrough
connector—designed for a PS/2 mouse, because it also
functions as a PS/2 to serial mouse conver-ter . (You can use it,
in fact, to attach a PC/AT

®

to a KVM switch or extender that

has only PS/2 mouse ports.) Plus, it’s hot-swappable.

The Keyboard and Mouse GHOST Emulator has both key­board connectors, as well as both output and passthrough PS/2
mouse connectors for mouse emulation and hot-swapping.
