The modular LINDY KVM Switch series U8/16
The U8/16 KVM switch series provides either 8 or 16 KVM server ports
supporting both PS/2 and USB keyboard and mouse connections.
This KVM switch series incorporates a modular concept design which
allows for dual console access. The local console port allows direct
access whilst a second console option permits remote access either via
remote IP or via a remote Cat.5 extender Unit. This option allows
system administrators to access and administrate their servers and
KVM switches from a remote office workstation. The required optional
IP or Cat.5 access modules can be purchased separately and are
simply installed into the back of a U8/16-Modular KVM Switch.
This manual also covers the KVM Switch U8/16-C, another version of
this modular KVM switch series that is used only in conjunction with the
modular LINDY KVM LCD Terminals U8/16-C. U8/16-C models can
only be installed in the back of an appropriate 19” LCD drawer and do
not have a display or front panel controls fitted. Any references to front
panel display and switch buttons in this manual does not apply to the
modular version U8/16-C.

1.1. About the U8/16 concept
The U8/16 series KVM switch supports traditional PS/2 mouse and keyboard connections as
well as modern USB connections. The U8/16 series supports the following computer platforms,
PC, Mac and SUN.
Combined KVM cables are used to connect the servers to the KVM switch’s computer ports.
Connections to the servers use a traditional VGA connector, one PS/2 mouse connector and
one USB mouse & keyboard connector. To connect a server via USB only the PS/2 connector is
not used; to connect the server via PS/2 the green PS/2 mouse connector is plugged into the
servers mouse port and a special USB to PS/2 keyboard adapter is attached to the USB cable
and then plugged into the server’s PS/2 port.
The U8/16 series KVM switch introduces a modular concept for dual console operation. In
addition to the local console port the switch also offers a secondary remote access option either
via IP or via a remote Cat.5 extender unit. Using this method, system administrators are able to
access and administrate their servers and KVM switches from a remote office workstation.
Depending on your application the appropriate optional access modules can be purchased
separately and are simply installed into the back of the U8/16-Modular KVM Switch.
This advanced 8/16 port KVM switch allows direct control of up to 16 computers from a single
KVM (Keyboard, Video, and Mouse) console. The switch can also be daisy chained with further
KVM Switch U8/16 to control up to 128 servers/workstations from 8 daisy chained 16 port KVM
switches.
Three methods of switching between the connected computers are available: 1. by pressing the
front panel push buttons; 2. by using keyboard hotkeys; or 3. via OSD (On Screen Display).
1.2. U8/16-Modular with IP Access module: U8/16-IP
KVM over IP technology allows a simple web browser interface to be used to access the switch
and the connected computers via a local area network (LAN) or, when connected to a wide area
network (WAN), access to the switch and the connected computers can be achieved from
almost anywhere in the world.

Section 1 Introducing the U8/16-IP
5
The U8/16-IP provides a non-intrusive solution for remote access and control because the
software runs on its embedded processors only, so there’s no interference with computer
operation, or impact on network performance. The U8/16-IP also features remote mass storage
support; a USB connection from the switch to one of the connected computers allows virtual
storage to be set up on the host and accessed from the client.
1.3. U8/16-Modular with Cat.5 Access module: U8/16-C5
If the Cat.5 KVM Extender module is installed it will allow remote access to the KVM switch
U8/16 and its connected servers via a dedicated Cat5e/6 RJ45 cable with a maximum length of
up to 100m @ 1024 x 768. The remote console consists of a Cat.5 Extender receiver unit which
is situated at the remote administrator’s desk. The remote receiver unit also includes a KVM
switch function which allows the administrator to either work on his local workstation or
alternatively switch to access the KVM switch and its connected servers.
The Cat5e/6 KVM Extender provides real time access without any signal conversion and
delays, whilst the IP Access module converts the VGA and keyboard/mouse signals into a
TCP/IP data stream and sends them via the LAN/WAN connection to the remote user. The
performance of the IP access connection and response time will vary depending upon available
bandwidth and traffic throughput.
1.4. KVM compatibility and backward compatibility with
LINDY P-series KVM switches
The U8/16 series KVM switches are compatible with almost any KVM switches using
STANDARD VGA, keyboard and mouse signals. The U8/16 is also compatible with older LINDY
P-Series KVM switches. Please note compatibility is only provided via the server ports of the
U8/16 series KVM switch but not via the daisy chain ports! Therefore when customers are
willing to mix U- and P-series KVMs (or other brand KVMs) it has to be done via port cascading
because daisy chain configuration of mixed U- and P-series KVMs cannot work. When using the
port cascading the main hotkey of the U-series KVM has to be changed (to an available hotkey
from the KVM OSD menu) so it will not conflict with the SCROLL LOCK hotkey of the P-series
KVMs or third party KVM switches.

2.2. Rackmount Installation
Before you start installation please verify that all
parts are included according to the package
contents.
If you want to install the KVM Switch in a 19” server
rack please attach the enclosed 19” rackmount
brackets using the screws provided.
2.3. Cascading / Daisy Chaining of multiple KVM Switches
At the time this manual was written (September 2007) the U8/16 KVM switch range may be
cascaded with other LINDY U-Series KVM switches only. Later versions of the new C5-8/16
series KVM switches will be introduced that will also be daisy chainable with the U series.
All other brands and models of KVM switches may be cascaded with LINDY U-series KVM
switches via the computer ports 1-16 of the U-series KVM switch.
To connect an additional SLAVE switch to the MASTER (or previous) switch, you must use the
included special KVM system daisy chain cable. Standard VGA cables may not work correctly
as not all cables support all pins connected.
Step 1 - Connect the local console
Connect your keyboard, mouse and monitor to the console ports of the U8/16 MASTER KVM
Switch.
Step 2 – Connect the first Slave
Use the daisy chain cable to connect the daisy chain port of the MASTER/previous KVM
Switch and the other end to the local console port of the next SLAVE switch.
Step 3 – Cascading / Daisy chaining
Repeat the previous step to daisy chain mores switches. Each individual switch in the chain
represents a different Bank. The MASTER switch is Bank 1 and each cascaded SLAVE follows
on as Bank 2, 3, 4 etc. You may cascade a maximum of eight switches/banks.
Bank 1 (Master)
Bank 3... to a maximum of 8
Cascading KVM Switches
by daisy chaining
Section 2 Hardware Installation
11
Step 4 – Resetting the Switches
After you have connected and switched on the SLAVE switches and computers, all of the KVM
switches may need to be reset. First, reset the SLAVE switch at the end of the daisy chain and
then reset all of the other SLAVE switches up to the MASTER U8/16 switch.
To reset the switch, press and hold the Bank button and port 8/16 button on the front panel of
the switch.
Each SLAVE switch should now show a dash in its BANK display.
Now, reset the MASTER switch - it will show a 1 in the BANK display. Each SLAVE switch
BANK display will now change to a number according to its position in the daisy chain.

3.1. KVM Switch Operation
3.1.1. Password Security
When you power on the U8/16 it will ask you for a user name and a password. The default
user name and default password for both is eight zeros –“00000000”. Please key in eight
zeros in the password field. You may use the “0” from the standard keypad but not from the
numeric keypad.
Note: Please don’t change the password until you are familiar with the operation of the OSD
menu – i.e. keep the default password “00000000”. Otherwise, if you forget the password, you
will need to send the switch back to LINDY for maintenance to clear the password.
The U8/16 OSD security feature offers up to 8 users + 1 SUPERVISOR.
A user specific access control list is available from the OSD of the KVM switch and can be
configured by the supervisor.
3.1.2. Hot Plug Support
The U8/16 supports a “Hot Plug” function for easy addition or removal of computers. The user
can arrange or maintain the computers and daisy chained KVM Switches as follows:
a. A computer can be disconnected and reconnected to the same or a different port of the KVM
switch without having to power it off as long as it is currently not connected to the console. In
most cases the PS/2 mouse and keyboard signals will be maintained and will not be lost.
b. The mouse driver of the computer has to support the hot plug function or the computer may
need to be rebooted when it is reconnected.
c. You can unplug your mouse or keyboard from the console port and plug it back in at any
time. You should not use different types of mice when performing this.
d. A SLAVE KVM switch can be added or removed at any time, but after adding or removing a
switch it may be required to reset all of the KVM switches. But you DO NOT need to reboot
the computers.
Please note: Some Operating Systems such as certain Unix versions are unable to
support the “Hot Plug” function. If you Hot Plug when using this kind of O.S., it may cause
unpredictable operation or may shut down the computer. Before attempting to use the Hot
Plug feature, please check that the O.S. and mouse driver support this function.
Important note: Your monitor will only display one PC signal at any one time. All
keyboard and mouse commands are sent to this PC only. After initial power up, port 1 is
active by default.
When a PC is connected to the currently selected port and it is not switched on,
or is in sleep mode, the monitor will not display any signal.

3.1.3. Computer / Port Selection
You can select the computer you want to access in one of three different ways:
Front panel push button selection
Keyboard hotkey selection
On screen display menu selection
3.1.4. Port LED Display
The front panel of the switch has two LEDs for each port.
When the LED labeled “P” is illuminated GREEN a computer attached to this port is powered
on. When the LED labeled “S” is illuminated RED, the KVM console is connected to this port. If
this LED flashes, the console is connected to this port but either no computer is attached, or the
attached computer is not switched on.
3.1.5 Front panel push button selection
You can select a computer by pressing the appropriate port push button. Each push button
refers to two ports. To access ports 1 to 8 simply press the button; to access ports 9 to 16 you
must push the button marked “
↵↵↵↵
” and the required port button simultaneously.
For cascaded KVM Switches you can ONLY use the port selection push buttons on the
MASTER U8/16 Switch to switch the SLAVES. You may also switch via OSD or keyboard
hotkey.
Section 3 KVM Switch Operation
15
3.2. Keyboard Hotkey Selection
You can also conveniently select the computer to be accessed and displayed by switching ports
through simple keyboard key sequences. To send commands to the KVM switch, the “SCROLL
LOCK” key must be pressed twice within 2 seconds. You will hear a beep to confirm that
the keyboard is in hotkey mode. If you have not pressed any key in hotkey mode within 2
seconds, the keyboard will return back to Operating System control status.
For the U-series KVM switches it is possible to change the “SCROLL LOCK” hotkey to certain
other hotkeys by selection from the OSD menu. This can help to prevent hotkey collisions with
other hotkeys from other devices. To do so you have to enter the Main OSD Menu by typing
SCROLL LOCK twice and then pressing the SPACEBAR within 2 seconds.
To invoke the On Screen Display Menu press the following hotkeys:
+ + = On Screen Display Menu
If the KVM switch prompts for your user name and password while no user names and
passwords have been assigned you may use eight zeros “00000000” for each, user name and
password.
Select F1: MAIN from the MAIN OSD Menu and then 06 HOTKEY to go to the hotkey selection
menu. Select any of the available hotkeys: Scroll Lock / Caps Lock / Left Ctrl / Right Ctrl / Left
Alt / Right Alt / Left Win / Right Win. Confirm your selection by pressing the ENTER key. From
now on the new hotkey is permanently changed.

access module. This module may either be a Cat.5 Extender or IP Access solution.
The Cat.5 Extender solution provides real time KVM access via a dedicated Cat5e/6 cable with
a maximum length of 300m. When using higher resolutions we suggest the following maximum
pixel resolution versus length: 1600x1200@75m/ 1280x1024@150m/1024x768@250m
Overall picture quality when using the Cat.5 extender will depend on the Cat.5/5e/6 cable
quality and also on the signal quality generated by the graphics card used. To optimize the
picture quality high quality amplifiers, equalizers and an auto skew compensation circuits are
used in the Cat.5 Receiver unit to compensate for the attenuation and for the different lengths of
the individual twisted pairs inside long Cat.5/5e/6 cables.
In comparison to the IP Access Extender solution the Cat.5 Extender provides a real time
analog KVM signal. And the Cat.5 KVM Extender does not require any software for operation as
it just operates as an analog KVM signal extender.
The Cat.5 KVM Extender module consists of two units: The local Cat.5 Extender Transmitter
module fitted into the KVM Switch slot and the remote Cat.5 Extender Receiver unit installed at
the remote user’s location.
The remote Cat.5 Extender Receiver unit includes a local KVM switch which allows the remote
user to also connect a local workstation to the receiver unit and switch between the local
workstation and remote KVM Switch access.
4.2. Cat.5 KVM Extender Installation
Before you install the local Cat.5 Extender Transmitter module into the KVM switch ensure all
connected computers are switched off and the power supply is unplugged. Proceed to unscrew
and remove the small metal cover on rear of the KVM switch. Carefully slide the module into the
slot and secure in place with the screw previously removed.
Now install the remote Cat.5 Extender Receiver unit at the remote user’s location. You will need
a VGA monitor and a USB mouse and keyboard to connect to the receiver unit. Connect your
local workstation to the receiver unit if required using the dedicated KVM system cable included
with the Cat.5 KVM Extender. Finally connect the Cat.5/5e/6 cable and the power supply unit.
The KVM cable provided can be used to connect either PS/2 or USB equipped computers in the
same way as previously described for connecting computers to the KVM switch in section 1.6.
A dedicated Cat5/5e/6 cable with RJ-45 connectors is required to connect the Receiver unit and
the Extender module located in the KVM switch. This connection must not be made via a “Live”
Ethernet connection but only via multiple cable segments using patch cables, patch panels and
wall sockets. Please consider the maximum resolution versus length limitations as mentioned
previously. Please also try to limit the number of connections between the transmitter and
receiver unit as this will help to reduce any signal loss introduced.
You may now proceed to power up all connected equipment and check for correct operation.

4.3. Cat.5 KVM Extender Operation
The Cat.5 Extender Receiver unit incorporates its own OSD menu which allows switching
between the local workstation and remote KVM Switch as well as configuration of the unit.
To invoke the hotkey and OSD operation of the Cat.5 Receiver unit simply press the hotkey
(factory default setting is Caps Lock) twice and press any other command from the list below
within 2 seconds:
Command Action
F1 Selects the OSD Help Menu of the receiver unit
F2 Selects the OSD Hotkey setting menu of the receiver unit
C Toggle between local workstation and remote KVM switch access
Q Turn ON / OFF the beep confirmation sound of the receiver unit
S Turn ON Autoscan functions of the receiver unit. Display will switch at 5
second intervals between the local workstation and the KVM switch
Press any key to stop scanning
A Auto adjusts the amplifiers and equalizers of the remote Cat.5 Extender
receiver unit. This auto adjustment is also performed automatically each
time the receiver unit is powered on
To change the default hotkey simply activate the local OSD F2 menu. Choose a new hotkey by
typing in the appropriate number key as listed in the local OSD F2 menu.
The following hotkeys are available: Scroll Lock / Caps Lock / Left Ctrl / Right Ctrl / Left Alt /
Right Alt / Left Win / Right Win. When choosing a new hotkey try to avoid using a hotkey
already used by any connected KVM switches as conflicts may arise when switching ports.

5.0.1. KVM over IP Access Features
The IP access module provides remote KVM over IP access to the KVM switch U8/16. It
converts all keyboard video and mouse signals and sends them as TCP/IP signals over your
LAN/WAN connection. The KVM switch U8/16 may be accessed from any computer connected
to your network and provides full KVM access including BIOS level access to all the connected
computers.
Please note that KVM over IP does not operate in a “real time” environment and that some
degree of time delay will occur due to limiting factors such as available bandwidth and network
traffic.
The KVM over IP Access module can be accessed via a simple web browser and via dedicated
software tools included with the product. It uses secure encrypted sessions and password
authentication protocols.
Please note that the conversion of video, mouse and keyboard signals requires a certain
amount of CPU processing time. Transporting large amounts of data over TCP/IP requires a
high bandwidth connection. Limited bandwidth may restrict or limit the possible screen
resolutions and colour depths which can be transmitted over your LAN / WAN.
A connection which exhibits limited bandwidth will result in slower mouse reaction and cursor
control. Also the available screen resolution, colour depth and refresh rates will also be affected.
Ensure the connection you are using provides adequate bandwidth, some adjustment of screen
resolution, colour depth and mouse cursor control may have to be made for satisfactory
operation.
5.0.2 KVM over IP Access Module Installation
Before you install the IP Access module into the KVM switch ensure all connected computers
are switched off and the power supply is unplugged. Proceed to unscrew and remove the small
metal cover on rear of the KVM switch. Carefully slide the module into the slot and secure in
place with the screw previously removed.
You may now proceed to power up all connected equipment and check for correct operation.
For the remainder of this manual the U8/16 KVM switch with installed KVM
over IP Module will be referred to as U8/16-IP.
