2. Introduction
The CAT5 Smart KVM Extender (KVM Extender) system from
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
* Wherever the word ‘computer’ appears in this guide it can
equally refer to a KVM switch.
3. The system components
The KVM Extender system consists of the following:
• Transmitter
• Receiver
• 3 in 1 CPU cable
• 1 Power adapter for the Receiver
A Shielded CAT5 FTP (Foil Shielded Twisted Pair) Solid
Wire 2x4x24 AWG cable terminated with RJ-45M connectors
connects the KVM Extender system. The Receiver can be up
to 110m/360ft away from the Transmitter.
This Guide illustrates the KVM Extender system and explains
how to install and operate it.

Place cables away from fluorescent lights, air conditioners,
and machines that are likely to generate electrical noise.

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, see Figure 3.
Figure 5 The 3 in 1 CPU cable
7. Power supply
Connect the Receiver to the power supply with the Power
adapter and Power 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 17.

11. Operating the KVM Extender
Once the system is connected there are 2 ways to switch
between the 2 computers / KVM workstations.
• On the Receiver press the Select button
Or
• On the keyboard press Shift followed by + or -.
When the Receiver works at its computer, its Control LED is
off. When the Receiver controls the Transmitter computer its
LED is on. The Receiver’s LED blinks when the Transmitter
controls its own computer.
At the Transmitter its Control LED remains off unless the
Receiver is working on the Transmitter computer.
Adjusting the picture
When the Receiver has control of the Transmitter’s computer,
adjust the picture quality where necessary using a small flat
screwdriver to turn the Picture adjuster located on the
Receiver’s rear panel. See Figure 4.
Timeout
When there are 2 workstations in the system you can gain
control at each workstation when the other workstation is idle
for 2 seconds. This timeout period can be altered in the settings
mode to between 1-99 seconds, as explained below.
Page 12
CAT5 SMART KVM EXTENDER
11
Locking KVM control
When there are 2 users using the system, either user can
override the Timeout feature and retain control indefinitely. Do
so by locking the system so that only one user has control.
To lock control:
On the keyboard press Shift followed by F12.
To relinquish control:
On the keyboard press Shift followed by Esc.
In the settings mode you can disable the lock control function.
This is explained in the Settings mode paragraph below.
12. KVM Extender Settings mode
Enter the Settings mode to:
• Change the hotkey
• Change the Timeout period
• Enable/disable lock control
• Make advanced adjustments
• View settings
To enter the Settings mode:
Press Shift then, F2. Release Shift before pressing F2. All 3
keyboard LEDs glow when in the Settings mode.
Page 13

Changing the hotkey
You can change the hotkey from Shift to Alt or Ctrl. Once
changed, all references in this Guide to Shift now refer to the
new hotkey.
To change the hotkey in the Settings mode:
To Type the letters
Alt HA
Ctrl HC
Shift HS
Changing the Timeout period
To change the Timeout period in the Settings mode:
Press T followed by a 2-digit time period of between 01-99
seconds. The 3 keyboard LEDs blink and the new setting is now
functional.
Enabling/disabling lock control
By default both users can lock control. You can disable the lock
control function.

Making advanced adjustments
The KVM Extender operates with:
• Windows, Linux, Novell or UNIX systems
• 2 or 3 or 5 button PS/2 mouse, Intellimouse or Wheel
mouse
When connected and switched on as set out above, the KVM
Extender automatically operates with the computer and mouse
types connected to it.
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:
In the Settings mode adjust the KVM Extender keyboard and
mouse modes to be compatible with the new computer. See the
tables below.

system that supports Wheel mouse functionality: (Windows 98
and Linux*).
Set the mouse setting to PS when the computer has an operating
system that does not support Wheel mouse functionality:
(Windows 95, NT4, DOS, Linux*, UNIX and Novell).
*Depending on the version.
Set the mouse setting to EP when the computer has an operating
system that supports Explorer mouse functionality: (Windows –
ME, 2000, and XP).
Replacing a mouse type
When a mouse is replaced with a different mouse type (not
necessarily a different mouse) while the KVM Extender is in
use, press and hold the Select button for more than 5 seconds.
Release the Select button after your monitor blinks once.
