Chapter 2: Overview
2. Introduction
Thank you for choosing the ServSwitch Agility Dual with VNC transmitter, part of the wider ServSwitch Agility family of products.
This advanced unit encodes high quality DVI video, audio and USB connections into Internet Protocol (IP) messages while offering
flexible signal switching capabilities and remote control facilities.
In concert with a ServSwitch Agility Dual receiver unit, the ServSwitch Agility Dual with VNC transmitter supports either two
single link DVI video streams or one dual link (very high resolution) DVI video stream. This is in addition to a microphone,
speakers and multiple USB peripherals. The distance between them is limited only by the size of your network.
ServSwitch Agility Dual with VNC provides a choice of link connections. Each unit supports both copper-based Gigabit
Ethernet cabling as well as Fibre Channel over Ethernet (FCoE). These can be used in parallel to provide up to 2 Gigabit connection speeds with the added benefit of link redundancy that can maintain operation in the event of a failed connection.
Additionally, the ServSwitch Agility Dual with VNC includes an in-built VNC server which allows it to stream low-bandwidth versions of its high-resolution output (via a dedicated Ethernet port on the front panel) so that it may be accessed remotely, via a VNC
viewer, through any standard network.
This concise guide acts as an addendum to the ServSwitch Agility and Agility Dual user guide to provide information about the extra features of your ServSwitch Agility Dual with VNC (ACR1012A-T).
2.1 Mixing ServSwitch Agility units
ServSwitch Agility Dual with VNC transmitters are complimentary to the standard ServSwitch Agility models which do not support dual DVI channels or fibre optic linking. It is possible to mix ServSwitch Agility, ServSwitch Agility Dual and ServSwitch
Agility Dual with VNC units on a network. However, whenever the two types are cross connected, the extra abilities of the
ServSwitch Agility Dual/ServSwitch Agility Dual with VNC units will be temporarily disabled.
2.2 ServSwitch Agility/Dual/VNC and ServSwitch iPath
Where multiple Agility units are used on a network, we have developed the ServSwitch iPath manager to allow comprehensive
and secure central control of all transmitters, receivers and users.
When using a ServSwitch iPath manager to configure Agility units, it is vital that all Agility units that you wish to locate and control are set to their factory default settings. Otherwise they will not be located by the iPath manager. If necessary, perform a fac-
tory reset on each Agility unit.

3.2.2 Local video link(s)
ServSwitch Agility Dual with VNC units can simultaneously support up to two Single Link high resolution video displays at pixel
clocks up to 165MHz; or can alternatively support a single Dual Link very high Resolution video display at pixel clocks up to
330MHz (equating to an example display mode of 2560 x 1600 at 60 Hz refresh). Use either a standard DVI-D cable (or
optionally a Dual Link DVI-D cable) to connect the primary video port of the computer system to the DVI-D-1 connector of
the ServSwitch Agility Dual with VNC. For dual link connections, a similar dual link cable must also be used at the remote unit.
Note: When using one very high resolution DVI-D dual link display, use a DVI-D Dual Link cable to connect the primary video port
of the computer system to the DVI-D-1 connector of the ServSwitch Agility Dual with VNC. A dual link cable must also be used at
the RX unit.
1 Wherever possible, ensure that power is disconnected from the ServSwitch Agility Dual with VNC and the host computer.

3 Connect the power cord to a nearby power supply socket. When all other connections have been made, switch on the power
supply unit.
Note: Both the unit and its power supply generate heat when in operation and will become warm to the touch. Do not enclose
them or place them in locations where air cannot circulate to cool the equipment. Do not operate the equipment in ambient temperatures exceeding 40oC. Do not place the products in contact with equipment whose surface temperature exceeds 40oC.
3.2.6.1 Power supply identification
Due to the increased power requirements of the ServSwitch Agility Dual and Agility Dual with VNC units, these models are supplied with larger capacity (20W) power adapters. The standard 12.5W and higher power 20W adapters use identical housings, so
within installations where both types are used, you need to double check the underside labels to differentiate the two types:
12.5W m odel

No damage will be caused if the 12.5W adapter (p/n
PS649-R3) and the 20W adapter (p/n PS650) are used
in place of each other on either of the Agility or Agility
Dual units. However, correct operation of Agility Dual
units can only be guaranteed if a 20W power adapter is
used. Always ensure that only the supplied (or
authorized replacement) 5-volt power supplies are used
to power the units.

ServSwitch Agility Dual with VNC
3.2.7 High speed links
ServSwitch Agility Dual (and Dual with VNC) units can be either connected directly to each other or via a high speed network.
The connections can be copper-based Gigabit Ethernet as well as Fibre Channel over Ethernet (FCoE). These can be used in parallel to provide up to 2 Gigabit connections speeds.
A single System port (Gigabit Ethernet) is provided as standard on the right side of the front panel. Additionally, the Teaming port,
located just to the left, allows you to insert either an optional Fibre Channel SFP module or Active Copper SFP module. The chosen module can then allow either a fibre optic or additional Gigabit Ethernet link to be used in parallel with the fixed System
(Gigabit Ethernet) port.
3.2.7.1 Using the Teaming port
1 Insert an appropriate optional SFP module into the aperture on the front panel:
Optional Fibre Channel or
Active Copper SFP module
2 Make your connection(s) between the chosen SFP module and either the other Agility Dual unit or a suitable network switch:
Transmit and
receive fibre links
Connect the transmit and receive
fibre optic links to the sockets on
the Fibre Channel SFP module.
Then close the latch over the link
connectors to lock them into place.

Chapter 3: Installation
3.2.7.2 Using the System port
1 Connect a CAT 5, 5e, 6, or 7 cable to the System port socket on the front panel:
CAT 5, 5e, 6, or 7 link either
directly from the other Agility
Dual unit or from a Gigabit
Ethernet switch
2 Connect the other end of the cable either to the other Agility Dual unit or to a Gigabit Ethernet switch, as appropriate.
3 [For connections via a network] repeat steps 1 and 2 for the other Agility Dual unit.
3.2.7.3 Cable and fibre details
• Fordirectlinks over Ethernet cable, the length of cable should not exceed 100 metres (328 feet). Network cables used for connections may be category 5, 5e, 6 or 7 twisted-pair cable. Agility Dual with VNC units have an autosensing capability on their
network interfaces, so for direct point-to-point connections, no ‘crossover’ Ethernet cable is required.

4. Configuration
The Agility Dual with VNC unit consists of two distinct sections (as detailed below) which each have their own separate configuration procedure:
The VNC port
Uses the standard Ethernet port on the left side of the
front panel and provides lower-bandwidth image video
feeds for use across standard networks and the wider
Internet.
Please see 4.2 The VNC port: Initial configuration
for details.
The System and Teaming ports
These use either the Gigabit Ethernet or (optional) Fibre Channel
over Ethernet (FCoE) module, on the right side of the front panel
and provide high resolution DVI-D image, audio and peripheral
feeds.
Please see the opposite page for details >>

Chapter 4: Configuration
4.1 System and Teaming ports: Initial configuration
Agility Dual with VNC units are designed to be as flexible as possible and this principle extends also to their configuration.
4.1.1 Direct linking
Where Agility transmitters and receivers (all models) are directly linked to each other, very little configuration action is required,
provided that they have their factory default settings in place. If the standard settings have been changed in a previous installation, you merely need to perform a factory reset on each unit (see below).
4.1.2 Networked linking
Where Agility transmitters and receivers (all models) are connected via networked links, you can either configure them individually,
or configure them collectively using an Agility iPath server:
• Configuring networked Agility units individually - You need to specify the network addresses of the Agility units so that
they can locate each other. This is done by running the browser-based configuration utility on a computer system linked
to the same network as the Agility units.
• Configuring Agility units collectively - The Agility iPath server allows you to configure, control and coordinate any number
of Agility transmitters and receivers from a single application.
IMPORTANT: When using Agility iPath to configure Agility Dual units, it is vital that all units that you wish to locate
and control are set to their factory default settings. Otherwise they will not be located by the iPath server. If necessary, perform a factory reset on each Agility Dual unit (see below).
4.1.3 Manual factory reset
A factory reset returns an Agility transmitter or receiver unit to its default configuration. You can perform factory resets using the
browser-based configuration utility or by using this direct manual method.
4.1.3.1 To perform a manual factory reset
1 Remove power from the unit.
2 Use a narrow implement (e.g. a straightened-out paper clip) to press-and-
hold the recessed reset button on the front panel. With the reset button still
pressed, re-apply power to the unit and then release the reset button:
Use a straightened-out paper
clip to press the reset button
while powering on the unit
After roughly eight seconds, when the factory reset has completed, five of
the front panel indicators will flash for a period of three seconds to indicate
a successful reset operation.

4.10 Video settings
This option provides a range of options related to the video configuration.
Video source
Selects which video input to use. It is
possible to display both single head
screens (if connected) or select one over
the other. If you are viewing Dual-Link
video resolutions, only one head will be
available.
Use Remote DDC
Uses the DDC of the monitors connect-
ed to the Agility Reciever. If this option
is un-ticked you can select a DDC to use
that is reported by the Agility Dual with
VNC.
Hot Plug Detect
When ticked, allows you to choose one
of four hot plug detect periods when,
after a display is connected, the DDC
information is sought.
Ignore Dithering
Dithering is a technique used by some graphics cards
to improve perceived image quality by continuously
slightly varying the colour of each pixel. This gives the
illusion of more shades of colour than the display can
really reproduce, and smooths the appearance of
gradually shaded areas in images. Unfortunately, dith-
ering is an issue for KVM extenders 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. This
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). ‘Ignore
Dithering’ is disabled by default to give full colour
accuracy and the best possible frame rate from non-
dithered video sources.
Threshold
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.

4.12 Virtual Media
The Virtual Media feature allows you to remotely make files available to a host computer that is linked to the Agility Dual with
VNC. 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
read-only 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 Agility Dual with VNC and a USB port on the
host computer.
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
Agility Dual with VNC. 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.
4.12.1 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 To remotely transfer

4.13 A rough guide to configuring TX and RX units
4.13.1 TX (transmitter) unit configuration
In an Agility dual system, the majority of configuration settings are dictated by the RX units. Therefore, the local TX unit setup
(using its browser-based configuration utility) is usually concerned only with three main factors: Its IP address details, the data
streams to enable/disable and video signal optimization. Other TX unit pages, such as USB Settings, System Messages, Firmware
Upgrades and Reboot are generally not used or altered during the majority of installations and are discussed elsewhere in this
guide. See Appendix A for explanations of all TX configuration page options.
Setting the TX address and output signal details
1 Display the TX unit System Configuration page.
2 Ensure that the IP address and netmask for the System port and the Teaming port (if used) are correct. The default settings of
169.254.1.33 and 169.254.1.43 for the two ports respectively are their zero config addresses - these are usually changed to
some other address suitable for your installation. Indeed, the zero config address for the System port MUST be changed before
the Teaming port can be used for network connections.
3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable Serial, if used) are enabled as appropri-
ate. There are similar options within the RX unit configuration and it is important that the settings in both units are the same. If
an option is ticked in one unit but unticked in the other, then that data stream will remain disabled. If you make a change,
remember to click the Update Now button.
Optimizing the TX video signal
Note: Where the Agility dual system is linked via two Gigabit links with sufficient available bandwidth, there should be no need to
alter the default settings on this page.
1 Display the TX unit System Configuration page and then change to the Video Configuration page.
2 Make changes to the controls as necessary for each video port. There is no single combination of adjustments that will suit all
installations, but generally:
• Ifcolorqualityisimportant,thenleaveColourDepthat24bitsandadjustothercontrols,
• Ifmovingvideo images are being shown frequently, then leave Frame Skipping at a low percentage and instead reduce the
Peak Bandwidth Limiter and Colour Depth.
• Wherescreensarequitestatic,tryincreasingtheBackgroundRefreshintervaland/orincreasingtheFrameskippingpercent-
age setting.
Make changes one at a time, in small steps, and view typical video images so that you can attribute positive or negative results
to the appropriate control.
See Video Configuration for individual explanations of the controls.
3 Click Update Now to apply each setting change.

Chapter 4: Configuration
4.13.2 RX (receiver) unit configuration
In an Agility dual system, it is the RX unit (receiver) that determines where and how data signals are sent (and received) by the TX
unit. Although numerous topologies (one-to-one, one-to-many, many-to-one, etc.) are made possible by the Agility system, they
are all dependent on two underlying modes of operation: either Unicast or Multicast transmission. Where multicast transmission is
not invoked for video and/or audio data, operation will be automatically served by unicast network transmission technologies.
The RX unit setup (using the System Configuration page of its browser-based configuration utility) is concerned with four main
factors: Its own IP address(es), the data streams to enable/disable, the IP address(es) of the TX unit and multicast transmission
details. Other pages, such as USB Settings, System Messages, Firmware Upgrades and Reboot are generally not used or altered
during the majority of installations. For further details about RX unit configuration pages, please see the Agility and Agility dual
guide.
Configuring the RX unit
1 Display the RX unit System Configuration page.
2 In the System Configuration section, ensure that the IP address and Netmask settings for the System and Teaming ports for this
RX unit are correct. The default settings of 169.254.1.32 and 169.254.1.42 for the two ports respectively are their zero config
addresses - these are usually changed to some other address suitable for your installation. Indeed, the zero config address for
the System port MUST be changed before the Teaming port can be used. Enter the new values and click the Update Now button. The System IP Address that is set here will be sent to the TX unit as the destination for transmitted data (when operating
in unicast mode). The Gateway entry is only necessary when the TX unit is located on a separate network to the RX unit.
3 Check that the data streams (Enable Video, Enable Audio and Enable USB - plus Enable Serial, if used) are enabled (ticked) or
disabled (unticked) as appropriate. There are similar options within the TX unit configuration; If one of these options is ticked in
one unit but unticked in the other, then that data stream will remain disabled. If you make a change, click the Update Now
button.
4 If necessary, alter the Audio Input Type to match your audio input. The line option is for a stereo line input, mic and mic boost
are for mono microphones, the latter benefiting from a +20dB gain boost.
5 In the Target Transmitter Unit Settings section, you need to enter the System port and Teaming port IP addresses for the TX
unit that will be supplying the video, audio, USB and serial data streams. This section allows you to determine which peripherals should use the second link. Most often all streams are supplied by the same TX unit, so common System and Teaming port
addresses can be applied to all streams. However, it is possible to receive them from different locations, in which case, click the
blue arrow to reveal the separate video, audio, USB and serial addresses. For all five peripherals, the System port of the targeted TX unit is always used to carry the respective data streams; your choices involve which of those five should also use the secondary Teaming port link to spread the load(s). For each peripheral, the first IP address is that of the targeted TX unit’s System
port. IP Address 2 corresponds to the Teaming port and is used only when the checkbox above is ticked. The default settings
for all entries are the standard IP addresses that are factory set within every TX unit (169.254.1.33 and 169.254.1.43). Change
these to the appropriate addresses on your transmitter(s) and click the Update Now button to save and activate them.

6 For installations that will include more than one RX unit, for either video or audio or both, then you need to configure the
Multicast Settings section.
The two Video and the single Audio Multicast sub-sections are configured in exactly the same way:
• First,ticktheEnableMulticast Video / Enable Multicast Audio check box.
• Next,enterappropriateMulticastAddressesfortheSystemportVideo/Audiodatastream(s).ThesetofIPaddresses
between 224.0.0.0 and 239.255.255.255 are specifically reserved for multicast operations. Within a private enterprise network, you merely need to choose a location that is currently unused. However, if your link will pass through public networks,
then attention must be given to finding an address within these limits that is not already reserved for special use. The IANA
(Internet Assigned Numbers Authority) website: iana.org provides a list of publicly reserved addresses.
• Next,enterappropriateMulticastAddress2entriesfortheTeamingportVideo/Audiodatastream(s).
The video and audio multicast addresses must be different, as must the System and Teaming ports The addresses that you
enter will be used by the RX unit to ‘listen-in’ on the video and audio data streams output by the TX unit. The same IP
addresses need to be set on every RX unit that will similarly receive the video and audio data streams.
7 Click the Update Now button to save.
Repeat the IP addressing and multicast configuration steps for all RX units that will be part of the one-to-many installation.
For most installations, the successful implementation of these configuration steps will result in a correctly working system.

4.14 Performing an upgrade
Agility Dual with VNC units are flash upgradeable using the method outlined here. However, for larger installations we recommend that you use the ServSwitch iPath manager to upgrade multiple Agility Dual units. When using the method below, the
Agility dual unit will be upgraded in sequence.
WARNING: During the upgrade process, ensure that power is not interrupted as this may leave the unit in an inoperable state.
If the upgrade process is interrupted and fails, it may be necessary to switch to the backup firmware image in order to regain
operation. See next page for details.
4.14.1 To upgrade a single unit via network link
1 Download the latest upgrade file from Black Box technical support.
Note: There are separate upgrade files for TX and RX units.
2 Temporarily connect the Agility Dual with VNC unit and a computer via a network (see browser-based configuration utili-
ty section for details).
3 Run a web browser on your computer and enter the IP address of the Agility Dual with VNC unit to be upgraded.
4 Click the Firmware Upgrade link. Within the Firmware Upgrade page, click the Choose File button. In the subsequent file dia-
log, locate the downloaded upgrade file - check that the file is correct for the unit being upgraded.
5 Click the Upgrade Now button. A progress bar will be displayed (however, if your screen is connected to the unit being
upgraded then video may be interrupted) and the indicators on the front panel will flash while the upgrade is in progress.
6 The indicators should stop flashing in less than one minute, after which the unit will automatically reboot itself. The upgrade
process is complete.

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 Agility Dual with VNC 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.

Encryption
Four options are available: Always On, Prefer Off, Prefer On, or Maximum. The one to choose depends on the specific details of
your installation. The use of encryption imposes a slight performance overhead of roughly 10% but is highly secure against third
party intrusion. Maximum selects 256 bit encryption.
Number of simultaneous VNC Users
Allows you to restrict the number of concurrent VNC sessions. The maximum number is 16 and the default is 4.
VNC Viewer Hot Key Sequence
When using the VNC Viewer, you can use key press combinations to select host computers and also to display the host selection
menu. This option allows you to choose which keys should be used to form the hotkeys that will precede a switching command.

Advanced unit configuration
Click this button to display advanced options that do not normally require alteration.
Force VNC Protocol 3.3
IMPORTANT: Protocol 3.3 is a legacy version that does not offer any encryption. Hashed passwords are not supported with 3.3
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
Use the arrow keys to alter the background refresh rate used to correct any screen changes missed in normal operation. The
options are: Slow, Medium, Fast, Auto or Disabled. The Auto option automatically varies the refresh rate when multiple VNC sessions are active to provide a balance between the sessions.
Note: When a low connection speed is detected, the background refresh is automatically disabled, regardless of the settings of
this option.

Appendices
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 Agility Dual with VNC 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
Determines what should occur when the limit on VNC users is reached. Options are: Replace oldest connection, Replace newest
connection and Don’t replace. Only non-administrator connections can be terminated in this way.
Enable Virtual Media
When ticked, allows the Virtual Media features to be used.

Time & date configuration
This page allows you to configure all aspects relating to time and date within the unit.
Use NTP
When this option is selected, the Agility Dual with VNC will synchronise its internal clocks using information from the (Network
Time Protocol) server listed in the NTP Server IP address field.
NTP Server IP address
Optionally enter the IP address for a known Network Time Protocol server.
Set Time from NTP Server
Click to immediately use the time and date information from the listed NTP server.

Appendices
Timezone specifier
Optionally enter a recognised timezone specifier related to the current position of the Agility Dual with VNC 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: m.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

ServSwitch Agility Dual with VNC
Network configuration
This page allows you to configure the various aspects of the IP port.
MAC address
Media Access Control address – this is the unique and unchangeable code that was hard coded within your Agility Dual with VNC
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.
IP Address
This is the identity of the Agility Dual with VNC within a network. The IP address can be thought of as the telephone number of
the Agility Dual with VNC. 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.
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.
Page 58
724-746-5500 | blackbox.com
Page 59
Appendices
IP Gateway
This is the address of the device that links the local network (to which the Agility Dual with VNC 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 Agility Dual with
VNC. 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.
724-746-5500 | blackbox.com
Page 59
Page 60
ServSwitch Agility Dual with VNC
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.

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 configura-
tion 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.

Appendix C. The KVMADMIN utility
Particularly useful for complex Agility Dual with VNC 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:
• DiscoverandadjusttheAgilityDualwithVNCconfiguration,includinghostsystems,
• SaveandrestoretheAgilityDualwithVNCconfiguration,
• 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 Agility Dual with VNC.
To use KVMADMIN you require the IP address and admin password of the Agility Dual with VNC 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 Agility Dual with VNC 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.

There are three manually selectable encoding methods which are accessible when the Auto
select option is unticked.
• 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 Agility Dual with VNC 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.
Colour level
The colour level is fixed at Medium (256 colours) for almost all browsers.
Inputs
View only (ignore mouse & keyboard)
When ticked, the viewer will not send keyboard or mouse information to the Agility Dual with
VNC or host computer.

Appendix E. Hotkey sequences
Agility Dual with VNC 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.
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.
