KVM IP Manager keeping control
For larger installations, the KVM IP Manager
application manages your hosts, devices and users
to enable quick configuration and secure, flexible
operation. A copy is included with every SC5-4xIP unit.
IP network/Internet
The IP port allows direct
connection to an Ethernetbased local network and
from there onto the wider
Internet.
Alternatively, the robust
SC5-4xIP security system will
allow direct connection to
the outside world.
Many computers
Each SC5-4xIP unit can directly support sixteen computer systems.

Global users
The unit can
support up to
four global users
at any one time.
Each user can
link to any host
computer for
which they have
permission.
Local user
One user can
be connected
directly to
the SC5-4xIP.
The local user
has the same
abilities and

global users.

All LINDY SC5 models provide full enterprise level
security to restrict access to authorised personnel.
Through the use of Console CAMs the SC5-4xIP also
allows global users to make console connections to
one or more specialist servers or network devices; thus
extending the flexibility of the remote management
facilities available.

Like the other models within the highly successful LINDY
SC5 family, this unit takes full advantage of category 5,
5e or 6 structured cabling to provide flexible installation
and configuration. Every connected computer is linked
by up to ten metres of standard CATx cable and one of
five types of CAM (Computer Access Module) according
to the port arrangements on each computer.
The SC5-4xIP can directly support up to sixteen
computers, however, this total can be increased to a
maximum of 256 by adding SC5 units in cascade to
provide a much larger network of controlled computers.

Thank you for choosing the SC5-4xIP from LINDY. This
compact unit allows one local user plus four global
users (located anywhere that has a network/internet
connection) to view and take full control of multiple
host computer systems.
Each global user simply requires a Real VNC client
application which is supplied on CD and can also be
downloaded from various locations, even from the SC54xIP unit itself. Alternatively, the unit can quickly serve
a Java applet to a global user, requiring only a standard
internet browser to operate.

Introduction
Each host system is linked using a Computer Access Module (CAM) and
category 5, 5e or 6 cabling to a maximum distance of 10m (32 ft) from
the SC5-4xIP unit.
Cascade installations can support a maximum of 256 host computers, however,
they impose the limitation that only a single host can be viewed by users at any
time. For more details see Appendix 7 - Cascading multiple units.

Enterprise installations are effectively limitless, you can keep adding SC5-4xIP
units and new hosts whenever and wherever required. For all but the most basic
enterprise configurations, the supplied KVM IP Manager utility becomes vitally
important: For users, it provides a virtualised and seamless way to access host
systems that are spread across multiple devices. For administrators, it creates
a centralised and secure method for managing all of those hosts, devices and
users. For further information, please see the user manual on the supplied KVM
IP Manager CD-ROM.

Alone, the SC5-4xIP can support sixteen host computers and allow up to five
users (four global and one local) to concurrently access any of those hosts. In
many cases the number of hosts will exceed these numbers and that is when the
flexibility of the LINDY SC5 range becomes apparent.
There are two main ways to increase the number of supported host computers:
• Cascade: Connect LINDY SC5 units to the ports of the master SC5-4xIP, then
connect the host computers to the SC5 units.
• Enterprise: Add further SC5-4xIP units and spread the hosts between them.

switched together. This type of operation is usually required where
each computer is fitted with multiple video cards or video cards with

It should be noted that the synchronisation cable deliberately does not have the transmit
pin of the Slave End connector linked to the receive pin of the Master End connector. To
do so would cause the Slave unit to be able to switch the Master unit. This would setup an
endless cyclical switching sequence that would prevent the SC5-4xIP devices from operating
correctly. For more details about the serial synchronisation cables, see Appendix 8.

the rear panel.
The sending device must use the following RS232
communication settings:
Baud rate: 19200 bps
Data bits: 8
Parity:
None
Stop bits: 1
No handshaking is implemented, however, valid command characters will be

Note: You must ensure that the SC5-4xIP unit has it Options serial ports set to
‘Sync Units’. This setting (together with the baud rate selection) can be made
either via the local or global user configuration menus.
The value of the byte received via the serial link determines which computer port

When setting up a new installation, the following stages are recommended:
1 Enable the general ‘Security’ option.
With security disabled (default setting), a local or remote user attached to
the SC5-4xIP will have full and unrestricted access to all computers and all
SC5-4xIP settings. In larger installations, you are strongly recommended to
enable security and set up individual user accounts with access privileges.
2 Create an ADMIN (administration) password.
All SC5-4xIP units have a fixed user account that cannot be deleted or
renamed, called ADMIN. If you intend to use security, then it is important to
allocate a password to the ADMIN account.
3 Create user accounts and allocate access rights.
Use the ADMIN account to add user profiles, passwords and access rights
for each of the system users.
4 Provide names for computers.
When numerous computers are attached, you are strongly advised to
provide names for each, to assist with recognition.
5 Configure the required ‘Setup Options’ and ‘Global Preferences’
Use the ADMIN account to determine key SC5-4xIP settings and timing
characteristics.

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four
encryption settings:
• Always on - This setting will ensure that the link is encrypted, regardless of
the SC5-4xIP encryption setting.
• Let server choose - This setting will follow the configuration of the SC54xIP. If the SC5-4xIP has ‘Always on’ or ‘Prefer on’ set, then the link will be
encrypted. If the ‘Prefer off’ setting is selected at the SC5-4xIP, then the link
will not be encrypted.
• Prefer off - This setting will configure an un-encrypted link if the SC5-4xIP
will allow it, otherwise it will be encrypted.
• Prefer on - If the SC5-4xIP allows it, this setting will configure an encrypted
link, otherwise it will be un-encrypted.

SC5-4xIP encryption settings
The SC5-4xIP configuration menu offers three encryption settings:
• Always on - This setting will force all viewers to use encryption. Note:
This setting will preclude any VNC viewer versions that do not support
encryption.
• Prefer off - This setting does not enforce encryption unless a viewer
specifically requests it. If a viewer has its ‘Let server choose’ setting, then an
un-encrypted link will be set up.
• Prefer on - This setting generally enforces encryption unless an earlier
viewer version is unable to support it, in which case the link will be unencrypted. If a viewer has its ‘Let server choose’ setting, then the link will be
encrypted.

The SC5-4xIP offers a great deal of flexibility in its configuration and this
extends equally to its encryption settings that are used to prevent unauthorised
interception of signals. Due to the variety of situations in which the SC5-4xIP
might be used and the range of viewer applications that need to view it, a
number of settings are available. The encryption settings to use depend upon
how the potential global users will operate.
Important factors to consider when setting these options might be:
• Do all global user connections and operations require encryption?
• Will some global users be using older VNC viewer versions?

Every network setup is different and great care needs to be taken when
introducing a powerful device such as the SC5-4xIP into an existing
configuration. A common cause of potential problems can be in clashes with
firewall configurations. For this reason the SC5-4xIP is designed to be intelligent,
flexible and secure. With the minimum of effort it can reside either behind the
firewall or alongside with its own separate Internet connection.

Positioning SC5-4xIP in the network
SC5-4xIP situated alongside the
firewall
IMPORTANT: When the SC5-4xIP is accessible from the public Internet connection,
you must ensure that sufficient security measures are employed.

Thanks to its robust security the SC5-4xIP offers you great flexibility in how it
integrates into an existing network structure. The SC5-4xIP is designed to reside
either on an internal network, behind a firewall/router or alternatively with its
own direct Internet connection.
24
Addressing
When the SC5-4xIP is situated within the local network, you will need to give
it an appropriate local IP address, IP network mask and default gateway. This
is achieved most easily using the DHCP server option which will apply these
details automatically. If a DHCP server is not available on the network, then
these details need to be applied manually in accordance with the network
administrator.
The firewall/router must then be informed to route incoming requests to port
5900 or port 80 (if available) through to the local address being used by the
SC5-4xIP.
When a web server is also on the local network
Port 80 is the standard port used by web (HTTP) servers. If the SC5-4xIP is
situated within a local network that also includes a web server or any other
device serving port 80 then, if you want to use the web browser interface from
outside the local network environment, the HTTP port number of the SC5-4xIP
may need to be changed.
When you change the HTTP port to anything other than 80, then each remote
browser user will need to specify the port address as well as the IP address. For
instance, if you set the HTTP port to ‘8000’ and the IP address is ‘192.168.47.10’
then browser users will need to enter:
http://192.168.47.10:8000
(Note the single colon that separates the IP address and the port number).
The firewall/router would also need to be informed to transfer all traffic to the
new port number through to the SC5-4xIP.

Port settings
As standard, the SC5-4xIP uses two ports to support its two types of viewer:
• Port 80 for users making contact with a web browser, and
• Port 5900 for those using the VNC viewer.
When these port numbers are used, VNC viewers and web browsers will locate
the SC5-4xIP correctly using only its network address. The firewall/router must
be informed to transfer any traffic requesting these port numbers through to the
SC5-4xIP.
If you need to change the VNC port number
If you change the VNC port to anything other than 5900, then each VNC viewer
user will need to specify the port address as well as the IP address. For instance,
if you set the VNC port to ‘11590’ and the IP address is ‘192.168.47.10’ then
VNC viewer users will need to enter:

A possible point of contention between the SC5-4xIP and a firewall can
occasionally arise over the use of IP ports. Every port through the firewall
represents a potential point of attack from outside and so it is advisable to
minimise the number of open ports. The SC5-4xIP usually uses two separate port
numbers, however, these are easily changeable and can even be combined into
a single port.
IMPORTANT: The correct configuration of routers and firewalls requires advanced
networking skills and intimate knowledge of the particular network. We cannot
provide specific advice on how to configure your network devices and strongly
recommend that such tasks are carried out by a qualified professional.

DNS addressing
As with any other network device, you can arrange for your SC5-4xIP to be
accessible using a name, rather than an IP address. This can be achieved in two
main ways:
• For small networks that do not have a DNS (Domain Name System) server,
edit the ‘hosts’ files on the appropriate remote systems. Using the hosts file,
you can manually link the SC5-4xIP address to the required name.
• For larger networks, declare the IP address and required name to the DNS
server of your local network.
The actual steps required to achieve either of these options are beyond the
scope of this document. 
To discover a DHCP-allocated IP address
Once a DHCP server has allocated an IP address, you will need to know it in
order to access the SC5-4xIP via a network connection. To discover the allocated
IP address:
1 In network section of either the local configuration menus or the global
configuration pages, set the ‘Use DHCP’ option to ‘Yes’ and select ‘Save’.
Once the page is saved, the SC5-4xIP will contact the DHCP server and
obtain a new address.
2 Re-enter the same ‘Network configuration’ screen where the new IP address
and network mask should be displayed.

Addressing
When the SC5-4xIP is situated alongside the firewall, it will require a public static
IP address (i.e. one provided by your Internet service provider).

Ensuring sufficient security
The security capabilities offered by the SC5-4xIP are only truly effective when
they are correctly used. An open or weak password or unencrypted link can
cause security loopholes and opportunities for potential intruders. For network
links in general and direct Internet connections in particular, you should carefully
consider and implement the following:
• Ensure that encryption is enabled.
By local configuration menu or global configuration page.
• Ensure that you have selected secure passwords with at least 8 characters
and a mixture of upper and lower case and numeric characters.
By global configuration page.
• Reserve the admin password for administration use only and use a nonadmin user profile for day-to-day access.
• Use the latest Secure VNC viewer (this has more in-built security than is
available with the Java viewer). To download the viewer.
• Use non-standard port numbers.
• Restrict the range of IP addresses that are allowed to access the SC5-4xIP to
only those that you will need to use. To restrict IP access.
• Do NOT Force VNC protocol 3.3.
• Ensure that the computer accessing the SC5-4xIP is clean of viruses and
spyware and has up-to-date firewall and anti-virus software loaded that is
appropriately configured.
• Avoid accessing the SC5-4xIP from public computers.
Ports
In this configuration there should be no constraints on the port numbers
because the SC5-4xIP will probably be the only device at that IP address.
Therefore, maintain the HTTP port as 80 and the VNC port as 5900.

IMPORTANT: If you make the SC5-4xIP accessible from the public Internet, care
should be taken to ensure that the maximum security available is activated. You
are strongly advised to enable encryption and use a strong password. Security
may be further improved by restricting client IP addresses, using a non-standard
port number for access.
Security can be further improved by using the following suggestions:
• Place the SC5-4xIP behind a firewall and use the port numbers to route the
VNC network traffic to an internal IP address.
• Review the activity log from time to time to check for unauthorised use.
• Lock your server consoles after they have been used.
A security white paper that gives further details is available upon request.

The SC5-4xIP is built from the ground-up to be secure. It employs a sophisticated
128bit public/private key system that has been rigorously analysed and found to
be highly secure. Therefore, you can position the SC5-4xIP alongside the firewall
and control hosts that are also IP connected within the local network.

The SC5-4xIP unit supports Console Server access to multiple devices (such
as dedicated specialist servers, Ethernet switches, IP routers, etc.) that are
connected to it via their RS-232 serial ports. Authorised global users can switch
to any of the connected devices and access them using either the Telnet or SSH
(Secure SHell) protocols.
Global connections are limited to a total of four concurrent sessions and these
can be all VNC sessions, all Console Server connections or a mixture of both.
Global users logon to Console Server connections using the same username and
password details as created for them for VNC global connections.
Setting serial connection parameters
The serial connection parameters are determined within the Console
Server Configuration page of the remote configuration menu (accessible
via VNC connection). Within that page you can apply a default set of
serial communication parameters to all ports that will be used for console
connections. Alternatively, the Console Server Port Configuration page allows
you to adjust each console port individually.

Within the Console Server Configuration page there are two key settings
which determine the base port addresses for Telnet and SSH connections into

global links through the unit to the required console server device, as discussed
next.

Special Console CAMs are used to connect each console device to the SC5-4xIP
unit. Each Console CAM is connected to the unit using a CATx lead as usual. On
its other side, each Console CAM has only a 9-way D-Sub female RS-232 serial
connection to link it to the server device.
The Options port on the rear of the unit can also be used as a Console Server
connection when it is configured to operate as such within the Serial Port page
of either the local menu or the remote menu.
All 16 ports of the SC5-4xIP can be used solely with Console CAMs, solely with
KVM CAMs or a mixture of the two types, as follows:
• If the entire unit is used solely for console connections then all 16 ports can
be used with Console CAMs. With the Options port also set into Console
Server mode, that provides a total of 17 possible console connections.
• If at least one KVM CAM is also used, then the maximum number of
Console CAMs that may be fitted falls slightly to a total of 13 (the Options
port is still useable as an extra console connection).
Note: If a KVM CAM is replaced by a Console CAM, the SC5-4xIP unit must be
rebooted or reset. This can be achieved either with a power cycle or remotely by
using Unit Configuration > Advanced Unit Configuration > Reset Unit button.

• Although there can be up to four concurrent global console server
connections, only one connection can be made to a Console Server port at
any one time (either using Telnet or SSH clients).
If a second global user attempts to connect with a port that is already being
accessed, a message such as ‘Port already in use’ will be displayed (the exact

message (the exact wording depends on the client being used).
• If a global user attempts to connect to a port that is not enabled for console

Select Host menu dot colours
Within the Select Host menu, each listed host has a coloured dot associated with
it to indicate its general status: Green for accessible, Red for inaccessible and
Blue to show a Console CAM connection which uses only a serial port.
There is, however, a fourth state where the dot turns Orange. An orange dot
against a host entry indicates that an inconsistency relating specifically to
cascaded hosts has been detected.
The problem can occur for two main reasons, either:
• A cascaded computer (or multiple computers) has been added to an
address such as 0301, however, there is still a registered entry for a directly
connected host at address 03. Thus, the now non-existent host at 03 will be
marked with an orange dot.
• A previously connected cascade has been removed and a computer
connected directly instead. This will cause all of the entries for the removed
cascaded hosts to be marked with orange dots. If they are not to be reinstated, then the administrator should delete the entries.
If you attempt to select an entry marked with an orange dot (by the menu,
by hotkeys or from the VNC viewer) you will see an error message stating
‘computer not connected’.

What will I see when I first login to a VNC session?
When you login to a VNC session, the result that you first see will depend on the
status of your username account:
• If you are using your username for the first time then no host will be initially
selected. Click the Hosts button to view a list (see Host selection for
details).
• If you have previously been logged in, the last host computer that you
viewed will be shown.
• If your username is already logged in at another location, then the host
computer currently being viewed in the existing session will be shown.
How do multiple users coexist?
Each of the four global users and also the local user can view any host computer
for which they have permission. More than one user can view the same host and
potential conflicts are arbitrated in the following ways:
• If a user views a host in private mode and then switches to a new host, then
the new host will also be viewed in private.
• If a user is viewing a host in shared mode when another user chooses the
same host but in private mode, the first user’s view will be blanked and a
message indicating that another user has taken private access will be given.
• If a user views a host in private mode and another user chooses the same
host, the second user will see a message indicating that the host is already
being viewed in private mode.
• If multiple users are viewing the same host and one switches to another host
then only that user moves to the new host, all other users are unaffected.

IMPORTANT: Optimal performance of the SC5-4xIP is dependant on the
calibration of the video for each host computer. For this reason, if you view an
uncalibrated host, the unit will invoke an automatic calibration after a pause of
roughly twenty seconds.
If the video is not calibrated the unit can operate slower than expected and will
affect all users. If you experience a drop in performance on the VNC viewers, try
recalibrating your viewer as a first step. Click the Auto calibrate button or access
the Video settings option from the ‘Controls’ button.
How do I remove traces of moved items from the screen?
When you move an item or window across the screen, sometimes it can leave
unsightly trails. These are called artifacts and can be particularly prevalent when the
connection speed is low. To remove artifacts, click the ‘Controls’ button and select
the ‘Refresh screen’ option. See Controls.
How do I make the most of a slow connection?

When you visit a host computer for the very first time, your viewer needs to
determine the optimum video and mouse settings for that particular computer.
The button will remind you to click it by flashing red when a new computer

to decrease unnecessary video information being sent across the link, thus
improving overall performance.
Once this has been done, providing you use the ‘Hosts’ button to switch
between host computers, the video settings for each machine will be re-used.
Note: When performing an auto calibration, ensure that the screen image
is static (no moving images) and also try to remove any on-screen displays
generated by KVM switches (such as host names or menus). This is because
they can affect the calibration process and result in a lower overall performance
level. For mouse calibration, ensure that there are no application windows
located around the upper left corner of the screen. This is because as the mouse
calibration takes place, the cursor may change (to match the application as it
skims across the window) and this may confuse the calculation. Also ensure that
the host computer does not have the mouse cursor trails option enabled.

Threshold
The threshold is effectively a
noise filter that differentiates
between valid video signals
and background noise or
interference. This has the effect
of reducing unnecessary video
signals between the SC5-4xIP
and the remote system, thus
improving performance.
Using automatic configurations
• Every setting can be individually subjected to an automatic configuration
(click the appropriate ‘Auto’ button) or can also be manually adjusted.
• Use the ‘Calibrate All’ button to automatically determine the optimum
settings for all items.
Note: Before using the ‘Calibrate All’ option, if possible, remove on-screen
display (OSD) elements generated by the SC5-4xIP (such as a menu). These
OSD elements use different video rates to those of the host system(s) and
can affect the setting of the automatic threshold value. SC5-4xIP uses an
improved calculation procedure to filter out the effect of these elements.
However, best results are obtained when the screen contains only host
system information.
Note: To maximise performance, the threshold level is automatically
increased by 50% when a slow link is detected.
Note: When the SC5-4xIP is used with one or more other switches, the
threshold needs to be higher than 32 due to the signal ‘noise’ that these
switches introduce. The SC5-4xIP configuration should detect such noise and
adjust the threshold accordingly.

Reduced Blanking
The Reduced Blanking
option can be enabled when
using flat panel display
monitors and helps to save
bandwidth without any loss
of performance. The blanking
period is present in all standard
video signals and is a small
time delay to allow the beam
of cathode ray tube displays
to return to the top left corner
of the screen. As flat panel
displays do not have a beam,
the blanking period can be
removed.

To enter a port number in VNC viewer
1 Enter the required IP address in the usual ‘Server’ box,
i.e. http://192.168.0.3
2 At the end of the IP address, add two colons (::) and then enter the port

i.e. http://192.168.0.3::8000
3 Continue with the standard VNC viewer instructions.
The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four
encryption options. The resulting actions of certain options depend upon how
the SC5-4xIP to which you are connecting is configured:
• Always on - This setting will ensure that the link is encrypted, regardless of
the SC5-4xIP encryption setting.
• Let server choose - This setting will follow the configuration of the SC54xIP. If the SC5-4xIP has a preference to encrypt the link, then it will be so,
otherwise the link will not be encrypted.
• Prefer off - This setting will configure an un-encrypted link if the SC5-4xIP
will allow it, otherwise it will be encrypted.
• Prefer on - If the SC5-4xIP allows it, this setting will configure an encrypted
link, otherwise it will be un-encrypted.
Whenever encryption does take place, the viewer will first need to create the
necessary secure key before the connection process can continue.

Mouse Switching
Settings: Enabled, Disabled
The computer channel can be switched using a three button mouse or
IntelliMouse. Pressing the central button or wheel button together with the
left hand mouse button will cause the SC5-4xIP to switch to the next available
computer.
When mouse switching is enabled, you can still use the middle button on its
own to control applications. Only when its pressed with the left or right button
is it interpreted by mouse switching, otherwise it is passed on to the host
application. The rotation action of an IntelliMouse wheel is not affected and is
always available to the computer application.
Screen Saver
Settings: Disabled; 2, 5, 10,15 or 20 Minutes
The SC5-4xIP can be set to blank the screen after no keyboard or mouse activity
has been detected for a selected timeout period. If preferred, the user can blank
the screen manually by selecting channel ‘0’ using the keyboard hotkeys or by
pressing ESC from the login screen.
OSD Dwell Time
Settings: 1, 2, 3, 5, 10 Seconds
After a successful computer channel change the SC5-4xIP will display a
confirmation message for a few seconds. The length of time that this
confirmation message dwells on the screen may be changed.
User Timeout
Settings: 1, 2, 5, 10, 30 Seconds, 1, 5, 10 Minutes
When no keyboard or mouse data has been received from an active user port for
the user timeout period, the SC5-4xIP will relinquish the control of that user port
in order to allow other users to access the host computer. The new port then
becomes the active port until it too times out. To avoid confusion between users
it is desirable to set the timeout period to be sufficiently long so that user’s work
is not needlessly interrupted by other users and sufficiently short to ensure good
overall system efficiency.

Logon Security
Settings: Disabled, Enabled
With security disabled there is no requirement for users to log-in to the system.
All users have full access to all the connected computers and full administration
rights. With security enabled, users are required to log-in to the SC5-4xIP. Each
user is allocated access rights to computers by the system administrator and they
are only able to see the computers that they have access to on their on-screen
menu.
HotKeys
Settings: Ctrl+Alt, Ctrl+Shift, Alt+Shift, Alt Gr, Left+Right Alt, Left Ctrl+Alt,
Right Ctrl+Alt
The keyboard hotkeys are special combinations of keys that, when used together
with certain keyboard “command keys”, perform special SC5-4xIP functions. For
example, pressing the hotkeys together with the “M” key will cause the onscreen menu to be displayed on your monitor. Other hotkey combinations allow
you to query which computer you are connected to and to move the on-screen
menu around the screen. You can also use the hotkeys together with the port
number to select a particular connected computer.
Auto Logout
Settings: Disabled, Enabled
The SC5-4xIP enables you to restrict access to your computers on a login basis.
If a user forgets to logout when they have finished accessing the SC5-4xIP then
the user console may unintentionally be left with full access to all the computers.
The SC5-4xIP can be set to automatically logout unattended user consoles when
the screen saver kicks in. This reduces the risk of security problems by preventing
user consoles remaining in a permanent “logged-in” state when there is no
keyboard or mouse activity. The automatic logout feature is only enabled when
the screen saver feature is active (i.e. not disabled).

MAC Address
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your SC5-4xIP unit when it was built. It consists of six
2-digit hexadecimal (base 16) numbers separated by colons. A section of the
MAC address identifies the manufacturer, while the remainder is effectively the
unique electronic serial number of your particular unit.
Use DHCP
DHCP stands for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks.
When this option is selected, your SC5-4xIP will attempt to locate a DHCP
server on the network. If such a server is located, it will supply three things to
the SC5-4xIP: an IP address, an IP network mask (also known as a Subnet mask)
and a Gateway address. These are not usually granted permanently, but on a
‘lease’ basis for a fixed amount of time or for as long as the SC5-4xIP remains
connected and switched on. Discover allocations.
IP Address
This is the identity of the SC5-4xIP within a network. The IP address can be
thought of as the telephone number of the SC5-4xIP. Unlike the MAC address,
the IP address can be altered to suit the network to which it is connected. It can
either be entered manually or configured automatically using the DHCP option.
When the DHCP option is enabled, this entry is unavailable. See IP addresses.
Gateway
This is the address of the device that links the local network (to which the
SC5-4xIP is connected) to another network such as the Internet. Usually this
is a network router and it will be used whenever a device to be contacted lies
outside the local network.
VNC Port
This is the logical link through which communications with a remote VNC viewer
will be channelled (see What is a port?). The default setting is 5900 which is
a widely recognised port number for use by VNC software. However, in certain
circumstances it may be advantageous to alter this number - see Security issues
with ports for more details.
Note: The VNC port and HTTP port can be set to the same port number in order
to simplify router and firewall configuration. If this is done then the SC5-4xIP will
“listen” for both types of traffic on the single port.
HTTP Port
This is the logical link through which communications with a remote web
browser will be channelled. The default setting of 80 is an established standard
for web (HTTP – HyperText Transfer Protocol) traffic though this can be changed
to suit your local network requirements.
Clear IP Access Control
This option removes all entries from the IP access control feature within the
SC5-4xIP. The IP access control feature (configurable by a global admin user)
allows certain network address ranges to be denied access to the SC5-4xIP. If set
incorrectly, it is possible to exclude all network users and so this option provides
an emergency recovery point.

Net Mask
Also often called the ‘subnet-mask’, this value is used alongside the IP address

Mouse Rate
Defines the rate at which mouse movement data are transmitted to the system. The
default option is 20ms, which equates to 50 mouse events per second. This is used to
slow down the rate in exceptional circumstances but normally requires no adjustment.
Force VNC Protocol 3.3
IMPORTANT: The use of this option is not recommended. Protocol 3.3 is a legacy
version that does not offer any encryption.
Idle Timeout
Determines the period of inactivity on a global connection before the user is logged
out. The idle timeout period can be set to any time span, expressed in minutes.
Note: The Screensaver option serves a similar purpose for local connections.
Protocol Timeout
Sets the time period by which responses should have been received to outgoing
data packets. If the stated period is exceeded, then a connection is considered
lost and terminated.
Session Sleep Timeout
Determines the period of inactivity before the viewer screen will blank and a
message is displayed. When no hosts are being viewed either because of this
time out or if no viewers are active then parts of the video circuitry are powered
down reducing power consumption by up to a third.
Single Mouse Mode Mouse Switch
Select the mouse button combination to exit from single mouse mode (when active).

Invokes optimised calibration techniques that handle the majority of mouse types.
Behaviour for admin connections when limit reached
Determines what should occur when four global connections already exist and
a fifth, administrator connection attempt is made. Options are: Replace oldest
connection, Replace newest connection and Don’t replace. Only non-administrator
connections can be terminated in this way.

Mouse Latency Allowance
This option is used during calibration to account for latency delays that may be
caused as signals pass through a device.
During calibration, the SC5-4xIP waits for 40ms after each mouse movement
before sampling the next. If a device adds a significant delay to the flow of data,
the calibration process can be lengthened or may fail entirely. The value entered
here is added to (or subtracted from) the default 40ms sampling time.
Note: You can enter negative values (down to -40) in order to speed up the
calibration process when using fast KVM switches. Use this option with caution
as it can adversely affect the calibration process.

Timezone specifier
Optionally enter a recognised timezone specifier related to the current position
of the SC5-4xIP unit. When an NTP server is used, the specifier will be used to
provide the correct real time.
The timezone specifier takes the following form:
std offset dst [offset],start[/time],end[/time]
The std and offset specify the standard time zone, such as GMT and 0, or CET

The time fields specify when, in the local time currently in effect, the change to
the other time occurs. If omitted, the default is 02:00:00.
Typical examples are:
UK: GMT0BST,M3.5.0/1,M10.5.0/2
Central Europe: CET-1CEST,M3.5.0/2,M10.5.0/3
US Eastern: EST5EDT,M3.2.0/2,M11.1.0/2
US Pacific: PST5PDT,M3.2.0/2,M11.1.0/2
Where: m specifies the month and must be between 1 and 12. The day d
must be between 0 (Sunday) and 6. The week w must be between 1 and 5;
week 1 is the first week in which day d occurs, and week 5 specifies the last d
day in the month.

IP Gateway
This is the address of the device that links the local network (to which the
SC5-4xIP is connected) to another network such as the wider Internet. Usually
the actual gateway is a network router and it will be used whenever a required
address lies outside the current network.
MAC address
Media Access Control address – this is the unique and unchangeable code that
was hard coded within your SC5-4xIP unit when it was built. It consists of six 2digit hexadecimal (base 16) numbers separated by colons. A section of the MAC
address identifies the manufacturer, while the remainder is effectively the unique
electronic serial number of your particular unit.
Use DHCP
DHCP is an acronym for ‘Dynamic Host Configuration Protocol’. Its function is
particularly useful when connecting to medium size or larger networks.
When this option is selected, your SC5-4xIP will attempt to locate a DHCP
server on the network. If such a server is located, it will supply three things to
the SC5-4xIP: an IP address, an IP network mask (also known as a Subnet mask)
and a Gateway address. These are not usually granted permanently, but on a
‘lease’ basis for a fixed amount of time or for as long as the SC5-4xIP remains
connected and switched on. Discover allocations.
VNC Port
This is the logical link through which communications with a remote VNC viewer
will be channelled (see What is a port?). The default setting is 5900 which is
a widely recognised port number for use by VNC software. However, in certain
circumstances it may be advantageous to alter this number - see ‘Security issues
with ports’ for more details.
HTTP Port
This is the logical link through which communications with a remote web
browser will be channelled (see What is a port?). The default setting of 80 is an
established standard for web (HTTP – HyperText Transfer Protocol) traffic though
this can be changed to suit your local network requirements.

IP Network Mask
Also often called the subnet-mask, this value is used alongside the IP address
to help define a smaller collection (or subnet) of devices on a network. In this
way a distinction is made between locally connected devices and ones that are
reachable elsewhere, such as on the wider Internet. This process helps to reduce
overall traffic on the network and hence speed up connections in general.

IP Address
This is the identity of the SC5-4xIP within a network. The IP address can be
thought of as the telephone number of the SC5-4xIP. Unlike the MAC address,
the IP address can be altered to suit the network to which it is connected. It can
either be entered manually or configured automatically using the DHCP option.
When the DHCP option is enabled, this entry is greyed out.

Mask
Enter an IP network mask

prefixed by ‘– ‘ are deny entries.
To define a new IP access control entry
1 Click the Add button to display a popup dialog:


The golden rule with this feature is ‘Include before you exclude’ or to put it
another way ‘Arrange allowed addresses in the list before the denied addresses’.
This is because the positions of entries in the list are vitally important. Once a
range of addresses is denied access, it is not possible to make exceptions for
particular addresses within that range. For instance, if the range of addresses
from A to F are denied access first, then the address C could not be granted
access lower down the list. Address C needs to be placed in the list before the
denied range.
IMPORTANT: This feature should be configured with extreme caution as it is
possible to deny access to everyone. If such an error occurs, see Clearing IP

192.168.142.154
192 is the most global part of the number (akin to the 0044 of the phone
number) and 154 is the most local (similar to the 754000 unique local code of
the phone number).
When two network devices communicate with each other, they always “dial the
whole number” regardless of their respective locations in a network. However,
they still need to know whether the other device is local to them or not, and this
is where the net mask comes into play.

As a rough analogy, consider how you use the telephone system. The phone
number for LINDY in the UK is 0044 (0)1642 754000. This number consists of
three distinct parts:
• 0044 connects from another country to the UK
• (0)1642 selects the main telephone exchange in the Thornaby area of
Stockton-on-Tees, and
• 754000 is the unique code for LINDY within Thornaby.
The important parts of the whole number depend on where you are. If you were
based in the same local area as LINDY, there would be no point in dialling out of
the UK, or even out of the area. The only part of the whole number that you are
interested in is the final part: 754000.
In a similar way to the various parts of the telephone number, the four sections
(or Octets) of every IP address have different meanings or “weights”. Consider
the following typical IP address:

192 168 142 000
192.168.142.000 = 192.168.142.000 ? Answer:YES
4
Address is local
1 The net mask is used to determine the local and global parts of the sender’s IP
address. Where there is 255 in the mask, the corresponding address slips through,
where there is a 0, it is blocked.
2 Where the net mask was 0, the corresponding part of the result is also zero - this
section is now known to be the local part of the IP address.
3 The same process is carried out for the destination address, again using the sender’s
net mask. Now the local parts of both addresses have been equalised to zero, because
their values are not important in determining whether they are both in the same local
network.
4 The results of the two net mask operations are now compared, if they match, the
destination is local. If not, then the sender will still use the same full destination IP
address but will also flag the message to go via the local network gateway and out
into the wider world.
The reason for doing this? It makes the network, as a whole, much more
efficient. If every message for every recipient was shoved straight out onto the
Internet, the whole thing would grind to a halt within seconds. Net masks keep
local traffic just that - local.


IP addresses
The net mask (or sub-net mask) informs a device as to its own position within a
network. From this it can determine whether any other device is within the same
local network or is situated further afield.
Taking the telephone number analogy given in the IP address section, in order
to use the telephone system efficiently, it is vital for you to know your location
relative to the person you are calling. In this way you avoid dialling unnecessary
numbers.
When one network device needs to talk to another, the first thing that it will
do is a quick calculation using its own IP address, the other device’s IP address
and its own net mask. Suppose a device with address 192.168.142.154 and
net mask 255.255.255.0 needed to communicate with a device at address
192.168.142.22. The sending device would perform several calculations:

Thus, when 154 is bit-wise ANDed with 240, the result is 144. Likewise, any
local address from 192.168.142.144 through to 192.168.142.159 would
produce exactly the same result when combined with this net mask, hence they
would all be local addresses. However, any difference in the upper three octets
or the upper four bits of the last octet would slip through the mask and the
address would be flagged as not being local.

Decimal octet prior to AND
operation with net mask

To really understand the operation of a net mask it is necessary to delve deeper
into the life blood of computers – binary; this is native digital, where everything
is either a 1 (one) or 0 (zero), on or off, yes or no.
The net mask operation described on the previous page is known as a ‘bit-wise
AND function’. The example of 255.255.255.0 is handy because the last octet
is completely zero and is “clean” for illustrative purposes. However, actual net
mask calculations are carried out, not on whole decimal numbers, but bit by bit
on binary numbers, hence the term ‘bit-wise’. In a real local network, a net mask
might be 255.255.255.240. Such an example would no longer be quite so clear,
until you look at the net mask in its binary form:
11111111.11111111.11111111.11110000
In this case, the four zeroes at the end of the net mask indicate that the local
part of the address is formed by only the last four bits. If you use the diagram
from the previous example and insert the new net mask, it will have the
following effect on the final result:

Net masks - the binary explanation
81
Address ranges
Although you can define ranges of addresses, due to the way that the mask
operates, there are certain restrictions on the particular ranges that can be set.
For any given address you can encompass neighbouring addresses in blocks of
either 2, 4, 8, 16, 32, 64, 128, etc. and these must fall on particular boundaries.
For instance, if you wanted to define the local address range:
192.168.142.67 to 192.168.142.93
The closest single block to cover the range would be the 32 addresses from:
192.168.142.64 to 192.168.142.95.
The mask needed to accomplish this would be: 255.255.255.224
When you look at the mask in binary, the picture becomes a little clearer. The
above mask has the form: 11111111.11111111.11111111.11100000
Ignoring the initial three octets, the final six zeroes of the mask would ensure
that the 32 addresses from .64 (01000000) to .95 (01011111) would all be
treated in the same manner. See Net masks - the binary explanation for
details.
When defining a mask, the important rule to remember is:
There must be no ‘ones’ to the right of a ‘zero’.
For instance, (ignoring the first three octets) you could not use a mask that had
11100110 because this would affect intermittent addresses within a range in an
impractical manner. The same rule applies across the octets. For example, if you
have zeroes in the third octet, then all of the fourth octet must be zeroes.
Number of addresses encompassed
1 address
2 addresses
4 addresses
8 addresses
16 addresses
32 addresses
64 addresses
128 addresses
256 addresses
If the access control range that you need to define is not possible using one
address and one mask, then you could break it down into two or more entries.
Each of these entries could then use smaller ranges (of differing sizes) that,
when combined with the other entries, cover the range that you require.
For instance, to accurately encompass the range in the earlier example:
192.168.142.67 to 192.168.142.93
You would need to define the following six address and mask combinations in
the IP access control section:
Network/address entry

192.168.142.68
192.168.142.72

Some of the simplest addresses to allow or deny are single locations. In this case
you enter the required IP address into the ‘Network/Address’ field and simply
enter the ‘Mask’ as 255.255.255.255 (255 used throughout the mask means
that every bit of the address will be compared and so there can only be one
unique address to match the one stated in the ‘Network/Address’ field).
The permissible mask values (for all octets) are as follows:

The settings of port numbers become important when the SC5-4xIP is situated
behind a network firewall. In order for a remote VNC viewer or web browser
to make contact with your SC5-4xIP, it is necessary for the firewall to allow
communication through a particular numbered port to occur.
One specific function of firewalls is to restrict access to ports in order to prevent
malicious attackers using them as a route into your network. Every new port
that is opened offers a new possibility for hackers and so the number of
accessible ports is purposefully kept to a minimum. In such cases, it may be
advantageous to change one or both SC5-4xIP ports to use the same number.
The other alternative is to place the SC5-4xIP unit outside the firewall and take
full advantage of its secure operation features – see Networking issues for
details.
IMPORTANT: The correct configuration of routers and firewalls requires advanced
networking skills and intimate knowledge of the particular network. We cannot
provide specific advice on how to configure your network devices and strongly
recommend that such tasks are carried out by a qualified professional.

Security issues with ports


If you accept the analogy of IP addresses being rather like telephone numbers,
then think of ports as extension numbers. In a company of any size, you
generally wouldn’t expect the accounts department to share the same telephone
with the technical department. Although their calls may all be related to the
same company, they concern very different aspects of that company.
It is the same with IP network connections. Although you have only one network
link into your computer and only one IP address (phone number), you are
probably performing many different tasks through that one link, often at the
same time. Thus, when you browse the web your outgoing requests and the
incoming information are all channelled through port 80. When you send an
email, it travels through port 25 and when you transfer files you are, without
knowing it, using port 20.
At the “border crossing” between the wider Internet and every local network
attached to it, there is a router that is usually combined with a firewall. One of
its main tasks is to direct incoming traffic to the correct place within its local
network. A key piece of information to help it do this is the port number:

The diagram shows how an SC5-4xIP unit and multiple SC5 units
can be cascaded to two levels. Computer systems can be connected
at any level. The local or global users can access computer systems
situated anywhere within the cascade tree.

When you need to control more than sixteen host
computers using SC5-4xIP units, there are two
main ways to achieve this:
• The preferred method is to use multiple SC54xIP units to control groups of sixteen hosts
and then use the KVM IP Manager utility to
manage the interactions of multiple users with
those hosts. This method is described in the
section Creating larger installations.
• The alternative method is to cascade SC5
units from the ports of the original SC5-4xIP
unit. Up to sixteen hosts can then be linked
to each of the secondary SC5 units. The
combination of LINDY units can be arranged
two levels deep forming a tree, or cascade
arrangement, with computer systems situated
at either level within that cascade tree.
The limitation of the latter method is that the local
and global users linking into the SC5-4xIP unit
can all only view one host system at a time due to
the single pathways formed by the connections
between the LINDY units.
This section details the configuration and
operation of a cascade system for completeness.
Note: It is not possible to cascade two SC5-4xIP
units together because they do not have a Remote
User Port on their front panels. The lower units
must always be the non-IP SC5 variants.

To connect units in cascade
1 Ensure that power is disconnected from the
SC5-4xIP and all other units to be connected.
2 Connect one end of the cascade link cable
to an appropriate COMPUTER CONNECTIONS
port on the rear panel of the SC5-4xIP.

The method for cascading SC5-4xIP and SC5 units is straightforward and
requires no hardware settings or lengthy configuration process.
The method of linking units is the same regardless of the cascade level, or
number of devices attached. Put simply:
• A single cascade link is made by connecting a computer connections
socket of the SC5-4xIP unit to the REMOTE user port socket of the SC5
unit below it.
Please consider the following when making cascade connections between units.
Tips for successful cascading
• The maximum number of levels for a cascade is two.
• For each cascade link, use a standard category 5, 5e or 6 twisted-pair cable,
terminated at each end with an RJ45 connector. There must be no crossover
connections within the cable. The cascade link cables can be up to 10m (32
feet) in length providing that the total length from the SC5-4xIP or SC5 to
any CAM also does not exceed 10m.
• The procedure given opposite may be carried out in any order but for clarity
the instruction will begin at the SC5-4xIP unit. The procedure remains the
same regardless of exactly which cascade levels are being connected. The
basic rule is that each link is made by connecting a computer connectionS
port of the SC5-4xIP (upper switch) to the REMOTE USER PORT (on the front
panel) of the SC5.

Using cascaded computers
In use, cascaded computers can be accessed using exactly the same methods
as for those connected directly to the SC5-4xIP. However, by far the easiest way
is to use the on screen menu. This is because it displays the computer names
and does not require any knowledge of port addresses. See either Selecting a

Computer systems connected within a cascade arrangement are addressed using
up to four digits, two for each cascade level. The pairs of digits specify which of
the COMPUTER CONNECTIONS ports on each of the SC5 units must be enabled to
reach a specific computer. In the diagram given here, a portion of the previous
cascade diagram indicates how the routes to two particular computers are
formed and addressed.
Each cascade level requires two digits, hence the computer marked in red
requires a longer address (1203) as it is situated at cascade level 2, compared to
the blue computer at the top level with its two digit port number.
The first time that you make a connection between an SC5-4xIP and an SC5,
the master unit will detect this and ask (via the on screen menu) if you want to
automatically add computers. If you choose ‘Yes’ then the ports on the cascade
will be automatically added to the on screen menu.

Example:
+-SCROLL+-SCROLL+1+ENTER
Press and release scroll twice, press 1 then enter then release all keys (equivalent
definition is +SCROLL-SCROLL+SCROLL-SCROLL+1+ENTER-1-ENTER)
Using abbreviations
To reduce the length of the key definitions, any unique abbreviation for a
key can be used. For example: “scroll”, “scr” and even “sc” all provide an
identifiable match for “ScrollLock” whereas “en” could not be used because it
might mean “Enter” or “End” (“ent” would be suitable for “Enter”).
Note: Hotkey sequences and abbreviations are not case sensitive.
For information about where to enter these codes, please see the section
