Chapter 2: Overview
2. Introduction
Drawing upon our long and successful history within the field of remote system control, we have taken our best KVM via IP
technology and miniaturized it. The result is the ServSwitch Wizard DXS - Digital, a highly responsive, cost efficient way to control
a single system from any remote position - worldwide.
In situations where a single system must be placed in a relatively isolated location and yet must be controlled from elsewhere,
then Wizard DXS - Digital is the solution. The host system can run its usual operating system completely unchanged and needs
only to be connected to the compact Wizard DXS - Digital unit. This ensures that there is no performance hit associated with
other remote solutions and also provides the authorized remote user with complete control. The remote user uses a compact VNC
viewer utility and can link to the Wizard DXS - Digital via any connected IP network, or via the Internet.
Four simultaneous remote users
Wizard DXS - Digital can support
Virtual Media feature
Allows an authorized remote user
to transfer files and folders to a host
computer, such that they appear as
though presented locally on removable
media (as would a memory stick or
CD-ROM). Via the IP network link, the
remote user can then control the host
and make use of the transferred files
and folders. An indispensable feature
when remotely upgrading or patching
distant host systems.
four remote users at any one time.
IP network/Internet
The IP port allows direct connection
to an Ethernet-based local network
and from there onto the wider
Internet, as required.
Alternatively, the robust Wizard DXS
- Digital security system will allow
direct connection to the outside
world.

What is the best screen resolution to use?
The best resolution for your computer is one that is larger than the screen of the host computer that you are viewing. This will allow
you to see everything without scrolling around. Alternatively, the VNC viewer can be set to scale the image to fit your screen, but
remember that some pixel dithering effect will be seen when scaling is used.
How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your viewing window you will need to scroll around to see all items.
The viewer window allows you to ‘bump scroll’ (only in full screen mode). This means that when your mouse cursor bumps
against the edge of the screen, the screen image will scroll across automatically.
How do I escape from full screen mode?
Press the F8 button. This button is changeable but is most often set to F8.
How do I make the most of a slow connection?
The VNC viewer is slightly better suited to slower connections than the browser viewer because it offers more options. Click the
Options button of the VNC viewer when entering the Wizard DXS - Digital address during log on.
Rate limit mouse events
When selected, this mode greatly reduces the mouse movement data that are sent to the host computer. When you move the
local mouse, the remote cursor will catch up roughly once per second.
5.2 Host selection
The Hosts button on the menu bar provides the quickest and most efficient way to switch between host computers. This is
because the button is close at hand, but also because the screen calibration details for each host are reused when this method of
switching is used.
Note: The Hosts button is displayed only when the switching details for two or more computers have been declared within the
configuration section by the admin user.
5.2.1 To select a host
1 Click the Hosts button to display a list of computers.
2 Click the required computer name to view and control it.
See Host configuration for details about programming new hosts into the Wizard DXS - Digital
(‘admin’ user status required).
5.3 Configure
This option is displayed only when you are logged on as the ‘admin’ user. When selected it provides access to a wide range of
Wizard DXS - Digital settings.
See Appendix D for more details.

5.4 Auto calibrate
Auto calibrate will calibrate the mouse only if relative mouse mode is selected.
This detects the mouse motion and will report back that the mouse has been calibrated correctly depending upon the operating
system.
See the notes on Advanced mouse configuration for more details.
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.
5.4.1 Re-synchronize mouse
If you find that your local mouse pointer and that of the host are not correctly synchronized, use this feature to re-align their
movements. This operation is also selectable from the Controls menu.
5.4 .1.1 To re-synchronize the mouse
1 Use the Hosts button to select the required computer.
2 Click the button and then click OK in the subsequent pop-up message.
Note: If you find that this doesn’t work, you may need to perform a mouse calibration again.
5.5 Access mode - shared/private
Up to four users can be simultaneously logged-in and all will view the same host. If you need to perform a sensitive task that
should not be viewed by other users, you can change the access mode to Private. This action prevents other users connecting at
the same time.
5.5.1.1 To change the access mode
1 Click one of the arrow buttons adjacent to the Shared/Private indicator.
5.6 Power switching
When configured (and where you have access rights) this option allows you to control the mains power input to the currently
selected host computer.
Note: This option is generally used to power cycle remote systems that have failed to respond. Before switching a system off,
ensure that all attempts have first been made to power it down through normal means.
5.6.1.1 To switch a system on or off
1 Use the Hosts button to select the required computer.
2 Click the Power button and then select the Switch on or Switch off option, as appropriate.

5.8 Controls
When clicked, this button reveals a menu of options concerned with keyboard, video and mouse
operation.
5.8.1 Single Mouse Mode
This mode is for fast network connections where the cursor response is sufficient to provide
instant visual feedback on the remote screen. When enabled, the cursor is ‘captured’ within the
viewer window until you use the ‘escape’ hot keys.
To quit from single mouse mode, press F8 and then P. Alternatively, enable and use the mouse
button escape sequences - see Advanced unit configuration for details.
The single mouse mode does not require calibration.
5.8.2 Resync Mouse
This option has the same effect as the button on the menu bar and re-synchronizes the local and remote mouse pointers.
5.8.3 Refresh Screen
This option refreshes the whole screen image to remove any artefacts from moved screen items. This is useful when using very
low refresh rates on slow speed communication links.
5.8.4 Mouse Control
This option displays a mouse control dialog and is useful when the remote cursor is failing to respond correctly to your mouse
movements, even after using the Resync mouse option.
The mouse control dialog allows you to control the remote mouse cursor using a selection of buttons that you click with your

Chapter 5: Operation
5.8.8 Video settings
This option provides a range of options related to the video configuration.
Dithering is a technique used by some graphics cards to improve perceived image quality by continuously slightly varying the color
of each pixel. This gives the illusion of more shades of color than the display can really reproduce, and smooths the appearance of
gradually shaded areas in images. Unfortunately, dithering is an issue for KVM extenders such as Wizard DXS - Digital because it
makes the image appear to be changing all the time even when it is static. This means that a great deal of unnecessary network
data is sent to the VNC viewer, reducing the video frame rate and making mouse response appear slow.
The Ignore Dithering option works by ignoring small variations in the video from frame to frame. It is disabled by default to give
full color accuracy and the best possible frame rate from non-dithered video sources.
Ignore Dithering
The ‘Ignore Dithering’ option increases performance and reduces network
traffic when the host computer is an Apple Mac or another computer that
has dithered video output. It also improves performance if the video source is
noisy (e.g. from a camera or a VGA-to-DVI converter).
The Threshold setting adjusts the level of dithering noise that is ignored. The ‘Auto’ button attempts to choose a suitable value
automatically, but the level can also be adjusted manually using the slider or arrow buttons. The best value is of course a
compromise between capturing all the ‘real’ screen changes whilst ignoring the (almost invisible) dithering noise. A good way to
choose the value is to watch the Display Activity indicator for a static screen. If the Threshold is too low, the Display Activity will
be a high percentage while nothing is really changing. If the Threshold is too high, the Display Activity will be very low (or zero)
but some real changes in the screen may be missed.

5.8.9 Sound control
This option provides a range of options related to the audio capabilities of the Wizard DXS - Digital.
Sample rate
The number of
audio samples per
second (in Hz).
8000 produces less
samples and hence
uses less network
bandwidth. 48000
(48KHz) produces
the best sound
reproduction.
Channels
Allows you to
choose between
Mono and Stereo.
Format
uLaw - Use when
transmitted data needs
to be minimised - 8-bit
compressed data.
Linear - Use when
high quality audio
performance is required
- 16-bit uncompressed
(raw) data is
transmitted.
Window size (ms)
The time frame
in which the
unit requires an
acknowledgement
from the remote
viewer when
data is sent. If
acknowledgements
are not received,
the unit will stop
sending audio data
- Click the Restart
Sound button.
Restart Sound
Click to reenable audio
transmission
following an
automatic
cutout. If cutouts
occur regularly,
try reducing
the sample rate
or format, or
increasing the
Window size
setting.
Threshold
The level above
which the audio level
should be before it is
considered to be not
background noise
and hence should
be transmitted. A
level of 25 means the
audio input needs to
be above 25% of the
maximum before it is
transmitted.
Halt timeout
Determines
how long to
wait once the
audio input
has stopped
before timing
out the audio
connection.
There are four
options: Off,
Short, Medium
and Long.
Min burst (ms)
The time period
for which the
audio input must
fall below the
threshold level
before audio
transmission
ceases.
Transmission
will begin again
as soon as the
threshold level
is once again
exceeded.
Settings can be adjusted to suit transmission characteristics and audio quality requirements (unsuitable audio settings can affect
video quality):
For use on slow links:
Format: uLaw
Sample rate: 8000
Channels: Mono
For maximum audio quality:
Format: Linear
Sample rate: 48000
Channels: Stereo
Where necessary, adjust the Window size, Threshold and Min burst settings until optimum audio output is obtained.

5.9 Virtual Media
The Virtual Media feature allows you to remotely make files available to a host computer that is linked to the Wizard DXS - Digital.
Disk drives, single files or collections of files and folders up to 2GB in size can be mounted via the VNC link, and appear as a readonly disk on the host. This can prove to be an invaluable tool when upgrading host computers from remote positions.
Note: The file transfer is in one direction only, from viewer to host.
Note: Virtual Media does not currently work with Apple Mac systems.
In order to use the Virtual Media feature, the VM link must be made between the Wizard DXS - Digital and a USB port on the
host computer. See Host computer connections for details.
There are two main ways to use Virtual Media:
• Createaread-only‘virtualdiskdrive’onthehostfromoneormorefileschosenattheviewerend.Thisisusefulforcopying
one or more files from the computer running the VNC viewer to the host computer. See below.
• Exportadiskdrive(e.g.CD,DVDorUSBflashdrive)fromtheviewercomputersoitappearsasadiskonthehostattachedto
Wizard DXS - Digital. A particular use for this is for booting or upgrading the remote host from a CD or other media that you
have at the viewer end.
5.9.1 Remotely transferring files to the host as a virtual disk drive
There are several methods of doing this. The easiest method depends on whether:
• Thefilesarealreadyontheclipboardoftheviewercomputer(followinganEdit -> Copy operation).
See 5.10.1.1 To remotely transfer files from the clipboard >>
or
• Thefilesstillneedtobeselected.See5.10.1.2 To select and remotely transfer files from the viewer computer >>
Note: When using Virtual Media features, within the VNC viewer properties, ensure that in the Inputs section, the Share
clipboard with server and the Enable file transfer options are enabled. See Appendix A for details.

5.10 Resetting the Wizard DXS - Digital to factory default
For situations where the IP address or the password has been forgotten, or the Wizard DXS - Digital is being reinstalled, it is
possible to reset the unit to its original factory settings. This erases all configuration such as hosts, users and passwords, and
restores the default network address.
5.10.1.1 To perform a factory reset:
1 Disconnect power and all other cables from the Wizard DXS - Digital unit.
2 Set Configuration Switch 2 to the ON (up) position.
3 Apply power to the unit (either from the power supply or via both USB cables).
4 Within five seconds set Switch 2 to the OFF (down) position.
Note: If the orange indicator illuminates while switch 2 is still in the ON position then it is too late to place it in the OFF
position. Power down and try again.
If the factory reset is successful, the orange indicator will flash once after fifteen seconds.
After the factory reset is complete, the unit will reboot and you can connect a VNC viewer to it using the default IP address:
192.168.1.42 to check that the configuration has been reset.

Appendix C. Java viewer options
When you are connecting to the Wizard DXS - Digital using the Java
viewer, a number of options are available.
Click here to
access the options
There are four options pages:
C.1 Encoding and color level
Auto select
When ticked, this option will examine the speed of your connection to the Wizard DXS - Digital
and apply the most suitable encoding method. This option is suggested for the majority of
installations.
Preferred encoding
There are three manually selectable encoding methods which are accessible when the Auto
select option is unticked.
Appendices
• ZRLE – This is a highly compressed method that is best suited to slow modem connections.
• Hextile – This method offers better performance than the ZRLE when used over a high
speed network because there is no need for the Wizard DXS - Digital to spend time highly compressing the data.
• Raw – This is a primitive, uncompressed method that is mainly used for technical support issues. You are recommended not to
use this method.
Color level
The color level is fixed at Medium (256 colors) for almost all browsers.
C.2 Inputs

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.
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.
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.
Background Refresh Rate

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 Wizard DXS - Digital 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.
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.
Single Mouse Mode Mouse Switch
Select the mouse button combination to exit from single mouse mode (when active).
Use Quick Mouse Calibration
Invokes optimized calibration techniques that handle the majority of mouse types.
Behaviour for admin connections when limit reached

Appendices
Timezone specifier
Optionally enter a recognised timezone specifier related to the current position of the Wizard DXS - Digital 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 and -1, or EST and 5, respectively.
The dst string and [offset] specify the name and offset for the corresponding Daylight Saving Time zone; if the offset is omitted,
it defaults to one hour ahead of standard time.
The remainder of the specification describes when Daylight Saving Time is in effect. The start field is when Daylight Saving Time
goes into effect and the end field is when the change is made back to standard time. The most common format used for the
daylight saving time is: Mm.w.d
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.
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

D.8 Network configuration (IPV4)
This page allows you to configure the various aspects of the IP port when it is used in IPV4 mode. For IPV6 mode, please see the
next page.
To get here
1 Using VNC viewer or a browser, log on
as the ‘admin’ user.
2 Click the ‘Configure’ button in the top
right corner.
3 Click the ‘Network Configuration’
option.
MAC address
Media Access Control address – this is the unique and unchangeable code that was hard coded within your Wizard DXS - Digital
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 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 Wizard DXS - Digital will attempt to locate a DHCP server on the network. If such a server is
located, it will supply three things to the Wizard DXS - Digital: 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 Wizard DXS - Digital remains connected and switched on. Discover allocations.
IP Address
This is the identity of the Wizard DXS - Digital within a network. The IP address can be thought of as the telephone number of
the Wizard DXS - Digital. 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.
Page 54
877-877-2269 | blackbox.com
Page 55
Appendices
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 Gateway
This is the address of the device that links the local network (to which the Wizard DXS - Digital 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.
VNC Port
This is the logical link through which communications with a remote VNC viewer will be channelled. 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. 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 Access Control
This section allows you to optionally specify ranges of addresses which will or won’t be granted access to the Wizard DXS Digital. If this option is left unchanged, then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from all IP addresses will
be permitted. See Setting IP access control for details.

MAC address
Media Access Control address – this is the unique and unchangeable code that was hard coded within your Wizard DXS - Digital
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.
Enable IPV6
Change this option to Yes only if the Wizard DXS - Digital unit is connected to an IPV6 compliant network.
IPV6 Addresses
This section is used to hold the IPv6 addresses for the Wizard DXS - Digital. A link local IPv6 address is automatically added using
the Stateless Address Auto Configuration protocol. Use the Add, Remove, Edit buttons to alter the address as necessary.
Page 56
877-877-2269 | blackbox.com
Page 57
Appendices
Use DHCPv6
When this option is set to Yes, the Wizard DXS - Digital will attempt to locate a DHCPv6 server on the network to derive a unique
IPv6 address for itself as well as an address for the IPv6 Gateway. These are not usually granted permanently, but on a ‘lease’
basis for a fixed amount of time or for as long as the Wizard DXS - Digital remains connected and switched on. Discover
allocations.
If this option is set to No, the Wizard DXS - Digital will use the Stateless Address Auto Configuration protocol to determine
its own IPv6 address. This will be shown in the IPV6 Addresses field and can be edited if necessary.
IP Gateway
This is the address of the device that links the local network (to which the Wizard DXS - Digital 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.
VNC Port
This is the logical link through which communications with a remote VNC viewer will be channelled. 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. 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 Access Control
This section allows you to optionally specify ranges of addresses which will or won’t be granted access to the Wizard DXS Digital. If this option is left unchanged, then the default entry of ‘+0.0.0.0/0.0.0.0’ ensures that access from all IP addresses will
be permitted. See Setting IP access control for details.

D.10 Setting IP access control
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, you will need to perform a reset to factory default settings in order to regain access.
In the list, access control addresses prefixed by ‘+’ are allow entries while those prefixed by ‘– ‘ are deny entries.
To define a new IP access control entry
1 Click the Add button to display a popup dialog:
Network/Address
Enter the network address
that is to be allowed or denied
access. If a range of addresses
is being specified then specify
any one of the addresses
within the range and use the
Mask entry to indicate the size
of the range.
Mask
Enter an IP network mask
that indicates the range of
addresses that are to be
allowed or denied access.
For instance, if only a single
specified IP address were to
be required, the mask entry
would be 255.255.255.255
in order to specify a single
location.
Access
Use the arrow buttons
to select either ‘Allow’ or
‘Deny’ as appropriate.
2 Enter the base network address, the mask and select the appropriate access setting.
3 Click the OK button.
To reorder access control entries
IMPORTANT: When reordering, ensure that any specific allowed addresses are listed higher in the list than any denied addresses.
Take care not to invoke any deny access settings that would exclude valid users.
1 In the access control list, click on the entry to be moved.
2 Click the Up or Down buttons as appropriate.
To edit/remove access control entries
1 In the access control list, click on the appropriate entry.
2 Click either the Edit or Remove button as appropriate.

D.13 Power switching configuration
Power switch configuration comprises two main steps:
• ConfiguretheOPTIONS serial port to the same speed as used by the power switch box(es), using the Serial port
configuration menu.
• ConfigurepowerONandOFFstringsforeachrelevanthostcomputer.
For each power port there needs to be a valid ‘Power ON string’ and similarly an appropriate ‘Power OFF string’. In each case, the
strings are a short sequence of characters that combine a port address and a power on or off value.
If a particular computer has more than one power input (and thus requires an equivalent number of power ports to control
them), collections of strings can be combined to switch all of the required ports together as a group.
To configure the power sequences for each host computer
1 Using VNC viewer or a browser, log on as the ‘admin’ user.
2 Click the ‘Configure’ button in the top right corner.
3 Click the ‘Host configuration’ option.

Power control sequences
Notes: The settings given below are for a particular type of power switch - other power switches may require different settings.
Please refer to your power switch documentation for details about codes required by other power switches.
The structure of each power sequence (OFF, ON or Reboot) is as follows:
/Pxy=z\0D
Where:
x is the switch box number,
y is the power port number,
z is ‘0’ for OFF or ‘1’ for ON
r is for Reboot, and
\0D represents Enter (or Carriage return).
Example 1
To switch ON port 5 of switch box 2, the code would be as follows:
• Powersequence: P25=1\0D
Example 2
To switch OFF port 8 of switch box 3, the code would be as follows:
• Powersequence: P38=0\ 0D
For details about operating this feature, see Power switching control within the Operation chapter.
To control two or more ports simultaneously
You can control up to four power ports using a single sequence. This is done using the same command structure as shown above,
plus a delay command, for each port. Immediately following a port command, insert the characters ‘\*’ before the next port
command, and so on up to four ports. For instance, to switch on ports 1 and 2 in the first power switch, the command line
would be:
P11=1\0D\*P12=1\0D

Appendices
Admin Password and LDAP Support
Even if LDAP authentication is enabled, the ‘admin’ user is still authenticated locally, using the traditional authentication technique
of matching to a locally sorted password.
Active Directory authentication process
Typically, Active Directory deployments are not configured for anonymous binding. Hence, in our implementation of LDAP and
Active Directory support for the Wizard DXS - Digital we have opted have a single username and password to bind to the
directory and authenticate.
In order to use the ARQ3 LDAP with Active Directory ensure that “Anonymous bind” is not checked in the LDAP configuration
menu.
The process of authentication and associated LDAP transactions are as follows. A user enters the username and password in the
VNC viewer authentication dialog. This username and password is used as the “binddn” and “bindpw” in the “simple bind
request” sent to the Active Directory server. Upon binding to the directory successfully, a LDAP search is performed for the same
username under the specified User Field in the specified Base DN . If the the search is successful then the authentication is
performed using the password entered by the user. If the password is accepted by the Active Directory server, then the process
of authentication is completed and the user is unbound from the directory.
Linux LDAP authentication process
In order to use the Wizard DXS - Digital LDAP with Linux LDAP ensure that “Anonymous bind” is checked in the LDAP
configuration menu.
The process of authentication and associated LDAP transactions are as follows. A user enters the username and password in the

Appendix E. Networking issues
Thanks to its robust security the Wizard DXS - Digital offers you great flexibility in how it integrates into an existing network
structure. The Wizard DXS - Digital is designed to reside either on an internal network, behind a firewall/router or alternatively
with its own direct Internet connection.
E.1 Positioning Wizard DXS - Digital in the network
Every network setup is different and great care needs to be taken when introducing a powerful device such as the Wizard DXS Digital into an existing configuration. A common cause of potential problems can be in clashes with firewall configurations. For
this reason the Wizard DXS - Digital is designed to be intelligent, flexible and secure. With the minimum of effort the Wizard DXS
- Digital can reside either behind the firewall or alongside with its own separate Internet connection.

E.2 Placing Wizard DXS - Digital behind a router or firewall
A possible point of contention between the Wizard DXS - Digital 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 Wizard DXS - Digital 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. Black Box cannot provide specific advice on how to configure your network devices and strongly recommend that
such tasks are carried out by a qualified professional.
Port settings
As standard, the Wizard DXS - Digital 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 Wizard DXS - Digital correctly using only its
network address. The firewall/router must be informed to transfer traffic, requesting these port numbers, through to the Wizard
DXS - Digital.
When a web server is also on the local network
Port 80 is the standard port used by web (HTTP) servers. If the Wizard DXS - Digital 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 Wizard DXS - Digital must 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:
htt p: / /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 Wizard DXS Digital.
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:
192.16 8 .47.10 ::1159 0
(Note the double colons that separate the IP address and port number).
The firewall/router would also need to be informed to transfer all traffic to the new port number through to the Wizard DXS Digital.

Addressing
When the Wizard DXS - Digital is situated within the local network, you will need to give it an appropriate local IP address and IP
network mask. 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 Wizard DXS - Digital.

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 Wizard DXS - Digital via a
network connection. To discover the allocated IP address:
1 Within Network configuration, set the ‘Use DHCP’ option to ‘Yes’ and select ‘Save’. Once the page is saved, the Wizard
DXS - Digital 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.
DNS addressing
As with any other network device, you can arrange for your Wizard DXS - Digital to be accessible using a name, rather than an IP
address. This can be achieved in two main ways:
• ForsmallnetworksthatdonothaveaDNS(DomainNameSystem)server,editthe‘hosts’filesontheappropriateremote
systems. Using the hosts file, you can manually link the Wizard DXS - Digital address to the required name.
• Forlargernetworks,declaretheIPaddressandrequirednametotheDNSserverofyourlocalnetwork.
The actual steps required to achieve either of these options are beyond the scope of this document.

E.3 Placing Wizard DXS - Digital alongside the firewall
Wizard DXS - Digital 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 Wizard DXS - Digital alongside the
firewall and control a computer that is also IP connected within the local network.
IMPORTANT: If you make the Wizard DXS - Digital 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.
Ensuring sufficient security
The security capabilities offered by the Wizard DXS - Digital are only truly effective when they are correctly used. A 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:
• Ensurethatencryption is enabled.
• Ensurethatyouhaveselectedsecure passwords with at least 8 characters and a mixture of upper and lower case and
numeric characters plus a special character.
• Reservetheadminpasswordforadministrationuseonlyanduseanon-adminuserprofileforday-to-dayaccess.
• UsethelatestSecureVNCviewer(thishasmorein-builtsecuritythanisavailablewiththeJavaviewer).

• Reviewtheactivitylogfromtimetotimetocheckforunauthorizeduse.
• Lockyourserverconsolesaftertheyhavebeenused.
Ports
In this configuration there should be no constraints on the port numbers because the Wizard DXS - Digital will probably be the
only device at that IP address. Therefore, maintain the HTTP port as 80 and the VNC port as 5900.
Addressing
When the Wizard DXS - Digital is situated alongside the firewall, it will require a public static IP address (i.e. one provided by your
Internet service provider).

Appendix F. An introduction to IPv6
During the initial design of the Internet, 4.3 billion seemed like an impossibly large number of device addresses, possibly more
than would ever be needed. It took nearly forty years, but finally the last remaining vacant address blocks within the current
Internet Protocol scheme (called IPv4) were assigned in February 2011.
The Internet Protocol is a crucial element of Internet operation and the eventual exhaustion of unique addresses was predicted
and acted upon many years ago. The replacement for IPv4 is known as IPv6 and was defined in December 1998. Since then its
uptake has been slow (reportedly used for less than 1% of Internet traffic in 2008) although this will increase rapidly as places
within the incumbent system are exhausted.
Vastly increased address space
The most notable feature of IPv6 is the size of its address space, put simply: It’s massive. By using 128 bits to define each IPv6
address (rather than the 32 bits used in IPv4), there are now 340 x 1036 unique addresses (that’s 340 trillion trillion trillion or as it
is correctly known, 340 undecillion).
The larger address size of IPv6 requires a different manner of notation. Instead of the four decimal numbers separated by dots
used for IPv4 (e.g. 192.168.0.1), IPv6 addresses consist of eight groups of four hexadecimal digits that are separated by colons
(e.g. 2002:00a2:67be:0000:0000:0e82:8723:a144) – each group of four digits represents 16 bits of the address. By necessity,
IPv6 addresses are quite long and so there are a couple of techniques to help reduce this in certain cases:
• Whereagrouphasoneormoreleadingzeroes,thesecanbeomitted.Intheaboveexample00a2 and 0e82 can be written a2
and e82, respectively.
• Whereoneormoreconsecutivegroupsconsistsolelyofzeroes,theycanbereplacedwithadoublecolon(::). In the above
example, the fourth and fifth groups could be replaced with the double colon, so that the whole line could be reduced to:
2002:a2:67be ::e 82:8723:a144. It is easy to return any such shortened address to the full version by replacing the double colons
with sufficient groups of zeroes until the total number of groups is returned to eight. For this to work it is essential that only
one set of consecutive zero groups within an address are replaced with a double colon.
Standard subnet size
Thanks to the new huge address space, IPv6 does not need to wring every last drop out of each address range and so it handles
address allocation in a different manner than its predecessor. Whereas IPv4 uses subnets of varying sizes (using the Subnet Mask
entry to define the size of each subnet), IPv6 subnets are (almost) all set to a standard size. A full 64 bits are used to define each
subnet, which means that every standard IPv6 subnet has use of an address space that is the square of the entire IPv4 address
space (that’s 1.8 x 1019 addresses per subnet). In those subnets, all addresses are valid host locations; gone are special address
formats for particular uses, such as broadcast traffic. Also, now that all standard subnets are the same size, the subnet mask is
another item that is made redundant under IPv6.
Page 74
877-877-2269 | blackbox.com
Page 75
Appendices
Address allocation
Every device attached to an IPv6 network usually has more than one address type. The two most common types are called a linklocal address and a global address and these can be assigned in a number of ways.
In IPv4, device addresses are most commonly assigned either manually or by using a Dynamic Host Configuration Protocol server
(DHCP). IPv6 also offers manual addressing and DHCP (now called DHCPv6 and fully supported by the Wizard DXS - Digital unit),
but also allows devices to automatically configure their own addresses using a series of steps defined as StateLess Address
AutoConfiguration (or SLAAC). The key parts of the SLAAC procedure occur roughly as follows:
• TheIPv6compliantdevicecreatesatentative local identifier which is usually derived from its fixed unique hardware identifier
(or MAC address). The local identifier is 64 bits in length (the lower half of the full 128 bit address) and this is one of the
advantages of having a fixed subnet size; it is very straightforward to automatically figure out the boundaries and contents of
the local network. This is exactly what the device does next with its tentative local identifier.
• ThedeviceusestheNeighbor Discovery Protocol (part of the Internet Control Message Protocol suite – IMCPv6) to check within
the local network whether its tentative local identifier is being used by any other device. If it is, then the device will create a
new one and start the process again. If the local identifier is unique within the local network, it is then combined with the
standard link-local prefix (fe80::) to form a valid link-local address. At this stage the address is valid only for communication
within the local network. The next stage is to replace the link-local prefix with a global prefix and then carry out a similar
procedure in order to prevent address duplication, resulting in a validated global address.
Mixing IPv4 and IPv6
Although IPv6 is based upon, and shares a number of similarities with IPv4, there are great differences in their address spaces and
other key details which mean that they are not directly compatible. This means that while computers and their operating systems
can support both types, IPv4 and IPv6 networks exist essentially as two parallel, independent entities with numerous cross over
points (known as relay routers). For the foreseeable future, while both versions coexist, exchanging traffic between them will
require many relay routers and various transition techniques.
One such technique involves IPv4-mapped IPv6 addresses. These are used in operating systems and applications that transparently
support both IP formats. In such cases IPv6 will be the native format with IPv4 fully supported whenever necessary. When an IPv4
address must be incorporated, it is placed into a special IPv6 address that has its first 80 bits set to zero and the next 16 bits set
to one. The remaining 32 bits are where the IPv4 address is embedded. When written, the address is an amalgam of the two
network types - ::ffff:192.0.2.128

Appendix G. The KVMADMIN utility
Particularly useful for complex Wizard DXS - Digital configurations and the control of remote installations, KVMADMIN is a
powerful administration tool.
KVMADMIN is based upon the established VNC viewer and uses the same security system. Rather than a graphical interface such
as the standard viewer, KVMADMIN uses command line control to provide the following administration facilities:
• DiscoverandadjusttheWizardDXS-Digitalconfiguration,includinghostsystems,
• SaveandrestoretheWizardDXS-Digitalconfiguration,
• Setusernamesandpasswords,
• Downloadtheeventlog,
The use of KVMADMIN is strictly limited to the ‘admin’ user and for security purposes it is not possible to retrieve user names or
passwords from the Wizard DXS - Digital.
To use KVMADMIN you require the IP address and admin password of the Wizard DXS - Digital unit. The command line is as
follows:
kvmadmin <command> <ip address> [<parameters>]
where <command> is one of the following:
• -setconfig<config-file>
• -getconfig<config-file>
• -setusers<csv-file>
• -getlog<log-file>
• -gethosts<csv-file>
• -sethosts<csv-file>
• -setmodes<csv-file>
For instance, the command line:
kvmadmin -getconfig kvm1.cfg 192.168.2.1
... downloads the current configuration from the Wizard DXS - Digital unit at the given address and stores it in the local file kvm1.
cfg.
Whereas the command line:
kvmadmin -setusers users.csv 192.168.2.1
... configures the usernames and passwords for the same unit from the local file users.csv.
For more information about KVMADMIN, please refer to the user notes supplied with the utility.

ServSwitch Wizard™ DXS - Digital
Appendix I. Hotkey sequences and Port Direct
Wizard DXS - Digital allows you to enter commands suitable for any KVM switch in order to choose from up to 128 host systems.
These switching commands can take the form of hotkey sequences that emulate standard keypress combinations or, for KVM
switches that support the Port Direct format, merely basic port numbers.
Hotkey sequences
Almost any combination of keypresses can be emulated using the following notations:
+ means press down the key that follows;
– means release the key that follows
+– means press and then release the key that follows
means add a delay. The standard delay period is 250ms, however, if a number immediately follows the asterisk, this will
*
define an alternate delay period (in milliseconds)
Notes
• The entries are not case sensitive.
• AllcharacterscanbeenteredusingtheirASCIIcodes,from32to126(i.e.A,B,C,…1,2,3etc.)withtheexceptionofthespecial
characters above.
• Itisnotnecessarytospecifyallkeystobereleasedattheendbecausetheyareallreleasedautomaticallyafterthelastcode.
• AnumberofKVMswitchesfromalternativemanufacturersusehotkeysequencesthatbeginwithapress/releaseofeitherthe
Scroll Lock or Ctrl keys. These often require a delay between the initial key press and the channel number to allow the switch
to respond. A 500ms delay is usually sufficient.
Examples
To send the command Ctrl + Alt 4 you should use the following: +Ctrl+Alt+4.
To send the command Ctrl + Alt 12 you should use the following: +Ctrl+ALT+ –1+2
(the ‘+–1’ entry causes the 1 key to be pressed and released before the 2 key is pressed).
To send the command Scroll lock 1 + Enter (with a 500ms delay) you should use the following: +–Scr*500+1+Ent

Creating macro sequences
Hot key macro sequences can be up to 256 characters long. All keys are assumed to be released at the end of a line, however,
you can also determine that a key is pressed and released within a sequence. Any of the following three examples will send a
command that emulates and a press and release of the Scroll Lock key:
+SCROLL-SCROLL
+-SCROLL
+SCROLL-
Example:
+-SCROLL+ -SCROLL+1+ ENTER
Press and release scroll twice, press 1 then enter then release all keys (equivalent definition is +SCROLL-SCROLL+SCROLLSCROLL+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 sections Host configuration or Keyboard control.
Port Direct
Port Direct is totally transparent communication system that allows supporting KVM switches and remote access devices to
communicate with each other. Using the keyboard connections that link each device, Port Direct allows:
• Acontrollingdevicetoprovideaddressdetailsoftherequiredport,theuser’snameandaccessrights,mousecalibrationand
video mode information.
• Acontrolleddevicetoconfirmtheaddressandotherdetailsofthecurrentport.
Such communication simplifies both the configuration and selection of systems, especially within a complex cascade structure.
Port Direct provides excellent security control to prevent users from accessing systems for which they do not access rights
(‘sideways movement’) because each unit is fully informed of each user’s precise access rights.
Port/host addressing using Port Direct
When adding new computers to the Hosts list, the option ‘Add entry for unrecognised host’ is provided to automatically add new
entries if a port is visited that does not already have a matching host entry. This is a useful option for simple KVM switch
configurations, but should be used with care when complex cascades of switches are being used as it may lead to more host
entries being added than are strictly necessary.
Additionally, you can specify the port number of the required system using the same format as if controlling the KVM switch
directly. Port numbers MUST be entered within square brackets and can be specified to a maximum of four cascaded levels.
Examples
[16] selects port 16 and is equivalent to the hotkey sequence +CTRL+ALT+–1+6
[4105] selects port 5 on a KVM switch that is cascaded through port group 41
