Minicom is an advanced KVM switch that performs the
following functions:
Extends KVM control over a computer* up to a
distance of 110m / 360ft
Gives 2 users at 2 workstations control of 1 computer*
A 2-port KVM switch for 1 or 2 users
* Throughout this guide ‘computer’ also means a KVM switch
3. The system components
The KVM Extender system consists of:
Transmitter
Receiver
3 in 1 CPU cable

6. The KVM Extender cables
The Transmitter comes with built-in KVM cables that connect
to the computer’s Video card, Mouse and Keyboard ports.
The 3 in 1 CPU cable
The 3 in 1 CPU cable –illustrated below – is only used when
the Receiver connects to a computer. The cable connects to the
Computer section of the Receiver rear panel.
Figure 5 3 in 1 CPU cable
7. Power supply
Connect the Receiver to the power supply with the Power
adapter and cord provided.
The Transmitter receives its power from the connected
computer and does not generally need an external power supply.
However, when cascading Smart Extenders, some of the
Transmitters need an external power supply. Use a Minicom
Power adapter p/n 5PS20025. The power supply specifications
are: Regulated 6VDC 2 Amp, minus on internal pin .
Cascading is discussed on page 16.

Replacing a computer
When a computer is replaced with a different computer type
while the KVM Extender is in use, we recommend turning the
new computer off before connecting it to the KVM Extender.
When turning the computers off is inconvenient, do the
following:
At the Receiver or Transmitter location, enter the Settings mode
to adjust the keyboard and mouse modes making them
compatible with the new computer. See the tables below.
