----------------- Introduction
Overview
The MyHopper KMH2 and KMH4 are computer switches
that allows access to two or four IBM compatible
computers respectively from one PS/2 keyboard, mouse
and monitor. Switching between computers is as easy
as pressing the push button or entering hot-key
commands from your keyboard. There is no interface
card and software to install and the MyHopper is
independent of the computer operating system.
Ready to run right out of the box, this Kit comes with
everything you need - a switch and complete cable sets,
just hook them up and go. By allowing one console to
manage all your computers, the MyHopper eliminates the
expense for extra consoles, the spaces for extra
peripherals and the time hopping around for accessing
different computers.

Initial Power-up
MyHopper comes with complete cable sets facilitating
computer connection. One side of the cable has an
HDB-15 connector and the other side has three
connectors (one HDB-15 and two mini-DIN6s). The PC
1 ~ PC 4 marks on the MyHopper are for computer
connection as shown in figure 3.
Make sure all computers and the MyHopper are
powered down during installation. You may power
up the computers after installation,. The MyHopper
can be powered from the computers.
This
procedure ensures the MyHopper receive computer
settings correctly when computer boots.
NOTE: You may hot plug any additional powered-down
computer to the MyHopper at any time after the initial
power up.
