Installation

This section will guide you through the hardware installation of your SV831DI or SV1631DI. Please read
through this section carefully and complete each step in the order listed.

6

1. Make sure all computers and devices are powered off.

2. Attach each of your managed computers to your StarView KVM switch using the ultra-thin 3-in-1

KVM cables. Use the 3-in-1 cables to connect one of the PC ports on the back of the switch to the
computer's keyboard, mouse, and video ports. For information on cascading your KVM, see “Cascade
Configuration.”

3. Attach your KVM switch to the SV1110IPEXT with the integrated KVM cable. Plug the male video

connector (blue) into the Console monitor port on the KVM switch and plug the female end of the
video cable (blue) into the Video (In) port on the back of the SV1110IPEXT. Plug the keyboard
(purple) and mouse (green) connectors into the KVM switch's Console keyboard and mouse ports and
plug the PS/2 connectors on the opposite end to the Host Keyboard and Host Mouse ports on the rear
panel of the SV1110IPEXT.

4. Plug a keyboard and mouse into the Local Keyboard and Local Mouse ports on the front of the

SV1110IPEXT.

5. Attach your monitor by connecting the monitor video cable to the Video (Out) port on the front of the

SV1110IPEXT.

6. Using standard Ethernet patch cables, connect the LAN and/or WAN ports on the back of the

SV1110IPEXT to your network (usually a router, hub/switch, or wall outlet).

NOTE: The LAN and WAN ports are factory-configured with different settings that can affect the
configuration method you wish to use with the SV1110IPEXT. See “Configuration Methods
Explained” on page 8 for more details.

7. Power on your KVM Control Over IP Console, your KVM Switch, and your computers.

IMPORTANT: If you connected the optional WAN connector on the SV1110IPEXT to your network, you
must also connect the optional second AC/DC adapter to the unit. This provides a load-balancing feature

between the two power sources and allows the unit to function if one adapter fails.

NOTE: If you are using cables other than those provided in the package or branded by StarTech.com,
ensure that the cables are of high quality and use the minimum possible distance necessary. Low quality or
excessively long (particularly video) cables between the host computer and the SV1110IPEXT could
degrade performance.

IMPORTANT: The SV1110IPEXT is convection-cooled. Ensure the vents on both sides are
unobstructed.

Configuration Methods Explained

The SV1110IPEXT offers three distinct methods for configuring the unit for your network. The method
that will work best for you will depend on your level of experience and your specific network
configuration.

Accessing Web Configuration Using DHCP

This method requires that your network implement DHCP (Dynamic Host Configuration Protocol), usually
on a server or network access device such as a router that dynamically allows devices to join the network
without pre-configuration. It also assumes that you will have easy access to your network’s DHCP log,
since you will need to know the IP address of the unit to complete the configuration over your Web
browser. (If you are unsure of how to access your network’s DHCP log, contact your System
Administrator for details.) If the unit is powered on and connected to the network via the LAN port on the
rear panel, it will automatically attempt to lease an IP address using DHCP. Before you can begin the
configuration process, you will need to access the DHCP log from your file server or other device that acts
as the DHCP server on the network. A simple DHCP log looks similar to the following:

The information displayed for your own network may vary significantly from the data displayed in the
above image, but should supply (at minimum) three essential details: IP address, MAC address, and device
(or machine) name for the computers and other devices connected to your network. The values for the
SV1110IPEXT tested above are as follows:

IP Address: 192.168.22.4
MAC Address: 00-0E-C5-00-08-1A
Device Name: (none)

The easiest way to identify your SV1110IPEXT on the network is by its MAC address, a unique hardware
identifier that is specific to your unit. The MAC address of the unit can be found on a white sticker on the
bottom of the SV1110IPEXT. Write down this number and keep it for future reference. Once you
locate the MAC address of your unit in the DHCP log, you can match it to its leased IP address and proceed
with the Web configuration.

9

NOTE: Once you have located the IP address of the SV1110IPEXT and wish to proceed with the Web
configuration, do not power off the unit or your DHCP server, since the KVM might lease a different IP
address. Should this happen, re-examine the DHCP log to verify the IP address again.

NOTE: DCHP functionality is not affected if you also connected the WAN port on the SV1100IPEXT to
your network (see below).

Accessing Web Configuration Using Static IP

Since some networks rely on static IP addresses (every device has a pre-configured IP address that does not
change), the DHCP access method described above is not applicable in those situations. To accommodate
this type of installation, the WAN port on the rear panel of the SV1110IPEXT is factory-configured with
its own IP address.

NOTE: If you connected the LAN port on the rear panel of the unit to your network but did not connect the
WAN port, you must disconnect the Ethernet cable from the LAN port and move it to the WAN port

before attempting a static IP installation. (If desired, you can return the cable to the LAN port if you
configure it with a static IP address during the configuration process.) If you have connected both the LAN
and WAN ports on the KVM to your network, you may proceed with a static IP Web configuration.

The following are the default values for the WAN port, configured at the factory:

IP Address: 192.168.1.123
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
Broadcast: 192.168.1.255

To access the Web configuration for this product, you will need to configure the workstation you are using
to the same subnet (255.255.255.0) and also assign it a valid IP address. For details on how to change the
IP address of your computer (if necessary), consult your documentation or System Administrator for
assistance.

NOTE: It is advisable to verify whether another device on your network is using the same IP address as
the SV1110IPEXT before connecting it to the network to avoid a conflict. Should an IP address conflict
occur with another device on the network, power off the conflicting device or assign it another IP address
before continuing the installation.

NOTE: Not all IP addresses are valid for a given subnet. If you are required to change your subnet (and
therefore IP address) to configure the unit, be sure the IP address you choose is within the allowable range
for the 255.255.255.0 subnet.

Once your computer is configured to the same subnet as the SV1110IPEXT, you can use the IP address

192.168.1.123 to access the Web configuration system.

Accessing Terminal Configuration Using a Serial Cable

Configuring the SV1110IPEXT using a serial cable is the best choice if you need to pre-configure the unit
before attaching it to a network, i.e. when sending to a branch office, customer site, etc. In general, the
Web configuration is far preferable because of its intuitive interface and the fact that you do not have to be
within close physical proximity to do the configuration. However, if you wish to use the serial cable
method to configure the SV1110IPEXT, you can use any typical communication software package (UNIX:
tip, cu, kermit, minicom; Windows: HyperTerminal, kermit).

Using a DB9 male-to-female (straight-through, not null-modem) connect the end of the cable with the male
connector to the DCE Serial port on the rear panel of the SV1110IPEXT. Connect the end with the female

10

connector to the serial port on the computer you are using to configure the unit. Configure the terminal
software with “8N1” settings:

Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1

Configuring the SV1110IPEXT

Using the Web Interface

The Web interface is the most intuitive way to configure the SV1110IPEXT. It also offers a Java-based
VNC client that you can use to control the host computer from a remote location. The SV1110IPEXT
supports any industry-standard HTML Web browser. You can access the Web interface by opening your
Web browser and entering the IP address of the SV1110IPEXT you wish to access/configure. The IP
address will be either a) the address assigned by your DHCP server as identified in the previous section, or
b) 192.168.1.123 if your network uses static IP addressing.

The Login Screen

Before you can access the Web configuration interface, you must enter a user name and password. The
default username and password as
shipped from the factory is
username admin with a password of

admin.

NOTE: Before the login screen

appears, your Web browser may
display a warning about an invalid
security certificate. This does not
affect the security of your data in
any way. Whenever you are

prompted about a certificate
security problem by your browser
or the Java VNC client, always
choose the option to continue. For

more information, please consult
Appendix A, “About Security
Certificate Warnings”.

The Home Screen

The Home screen serves two functions. First, it is a place to check the status of the SV1110IPEXT, view
essential system information, and
capture screen shots from the host
computer. Second, it is where you
can start the integrated Java VNC
client to interact with the host
computer by clicking on the large
screen shot or choosing one of the
VNC client links.

The Admin/Setup Screen

This is the menu that will allow you
to access all the features you will
need to perform an initial
configuration of the SV1110IPEXT.
Each of the options is explained in
detail here.

Network Configuration (IP address. Netmask, etc).

Dynamic Host
Configuration Protocol
(DHCP)

Automatic network configuration
using DHCP is: Enabled/Disabled.
This feature applies only to the
LAN port on the rear panel, and is
enabled by default. When enabled,
the unit will automatically configure
itself with an IP address when a
DHCP server is present. When
disabled, the LAN port will use the
values assigned to it on the IP
Addresses and Routing table
below.

Current DHCP Lease
Information

This box provides detailed information about the IP lease that the unit has obtained from the DHCP server.

IP Addresses and Routing

This table allows you to assign IP
information for the LAN and WAN
ports separately. If you are using
DHCP, the values for the LAN port
will be filled in automatically and
any changes made will not affect the
setup. If Ethernet Bridging is
enabled (see below) the WAN port

12

will use the same settings as the LAN
port, and any changes will not affect the
setup for that port. Adjusting the setting
for the WAN port allows you greater
control over how the SV1110IPEXT is
configured for access from outside the
local network, particularly if a firewall
or proxy is in use.

Domain Name Server (optional)

This section allows you to specify DNS
servers and the default DNS domain
suffix in use on the network. If DHCP is
enabled, some of these values may be
supplied automatically.

Commit Network Changes

Clicking the Commit button applies any
changes made on the page to the
configuration, but leaves the old settings
active until the next time the unit restarts. Clicking Make changes effective now applies the changes and
restarts the SV1110IPEXT so the new settings take effect immediately.

Ethernet Bridging

When Ethernet bridging is enabled, the two Ethernet ports are virtually connected inside the
SV1110IPEXT. Packets arriving on either port that are not meant for it will be forwarded out to the other
port, when appropriate. IEEE-802.1d (“Spanning Tree Protocol”) is implemented to avoid broadcast storms
and to determine the topology of the network.
You may enable this feature so that the module can be inserted inline with the host it monitors. This
reduces the wiring and number of Ethernet ports required. Alternatively, you may connect both the WAN
and LAN ports to the same logical network through redundant Ethernet switches. If one switch fails, the
other will be used. When
bridging is enabled, both ports
share the same configuration
(DHCP or static IP addresses)
and the WAN port may not be
separately configured. Using
DHCP with Bridging increases
boot time, because the 802.1d
(STP) algorithm must finish
before the DHCP broadcast can
go out. To change this setting,
select either Enabled or Disabled from the drop-down menu and click Commit and Apply.

Setup compatibility with host system, external KVM, external power bar.

This menu offers features that may offer enhanced functionality with certain KVM and power products.
These can be left at their default values in many situations.

Port numbers to be used for different services.

Takes you to the Ports menu (see below).

13

SNMP agent setup and configuration.

This menu allows you to configure the SV1110IPEXT so it can be recognized and managed using industry­standard Simple Network Management Protocol software.

Debug network setup values and routing.

Takes you to the Status menu (see below).

Security policy,
internal firewall and
master password.

This menu allows you to
configure a number of
settings, including
changing the default
password for admin
(recommended). Read and
consider the comments and
instructions on this menu
before making any changes, as changing these features could make the unit inaccessible through Web
configuration (i.e. due to firewall filtering). Note that any password changes you make will have to be
entered in duplicate to reduce the chance of
error.

RADIUS authentication setup.

The RADIUS server requires the IP
address, the UDP port number (1812 ­default or 1645) and the shared secret.
The shared secret is used to encrypt
communications and corresponds to a
shared password for the RADIUS
server and the client machine. Two
additional servers may be defined for
backup purposes. Each server will be
tried in order, using the indicated
number of retries and timeout period,
which are configurable on the same
page. Remember to enable RADIUS
after configuring it. While RADIUS
authentication is enabled, the locally
defined accounts on the KVM control over IP module will not be used, except for the SSH login. However,
if a user name of the form
“name.local” is given at the RADIUS
prompt, the system will use “name”;
check the password locally, and skip
RADIUS authentication. Delete all
local accounts to avoid this behavior.
When connecting via VNC, a login
screen is generated that asks for a
RADIUS username and password.

14

User accounts: add, delete and change passwords.

This menu will allow you to add accounts other than admin to the system. These accounts will not have
the authority to change settings, but can access the Web interface and log in the VNC console. Selecting
Delete permanently removes the user from the system. If you enter values for a user that does not already
exist under Edit User Details, the system will create that user for you when you click Record changes. If
the user already exists, you will change the password for that user.

Firmware and flash memory management.

The firmware on the KVM control over IP is field upgradeable. To upgrade to another version, login as

admin.

Auto Self Upgrade

The KVM control over IP module
includes an innovative feature allowing
the unit to upgrade itself over the
Internet. Simply click on the button
labeled Upgrade to Latest and the
module will go out to the Internet and
download the latest version of the system
firmware and then install it. If the
module cannot access the Internet
directly (perhaps due to a web proxy or
other firewalls), then a page will be
shown that causes your browser to
download the required file. Save this file
to disk and then upload it as described in
the next section, Manual Upload. The
main FPGA is upgraded separately, and
has its own Get latest button. This file is
unique for each unit, so it must be done
in this manner.
If you have multiple units to upgrade, you may choose the Get latest version button that will not attempt to
upgrade the unit directly, but will instead fetch the required file. This file can be uploaded to multiple units
manually.

Manual Upload

Enter the name of the firmware file that you received from StarTech.com into the field provided (or use the
Browse... button). Press Start Upload and wait until a successful upload message is shown.

NOTE: Remember the following during the firmware upgrade…

• Do NOT turn off power to unit before this operation completes successfully. It may take several

minutes to write to flash memory.

• The unit will sometimes reboot as part of the upgrade procedure, depending on which system

component is upgraded. You will have to reconnect and re-login in those cases.

• Wait at least two minutes after pressing Start. Do not assume the upload did not work. There is no

status indicator bar to show the progress of the upload. The upload could simply be slow.

• Each file that is distributed upgrades a different component of the system. Therefore, be sure to apply

all files you are given as part of an upgrade. The system knows what to do with each file you give it,
and they are checked for validity before being applied.

15

Software Options Upgrade

Certain firmware features may be offered separately from the base unit, in order to reduce the initial cost
for the KVM control over IP module.
NOTE: If you wish to upgrade after the system is in operation, go to the Manage Firmware page and scroll
down to the section entitled Purchase Options.
Look for a unique code, like the following one:

4-C80C-B960-1-0
If you provide this code to the technical support department, they can give you an unlock code that will
open any feature you request. Types in the code provided, exactly, into the area provided and click
“Submit”. The new features opened by the code will be enabled immediately, but you may need to reboot
the unit to begin using certain features.

Set date and time.

Allows you to set the unit to local or Universal Coordinated Time (GMT).

Change system identification.

Provides details about this SV1110IPEXT that will be available to DHCP servers, SNMP agents,

and VNC clients. While these values do not affect the operation of the unit, they make it easier to

manage on the network.

The File Transfer Screen

The SV1110IPEXT is able to
emulate a disk driver attached
to the host via USB. Depending
on configuration, it will appear
to the host as a floppy drive
(1.44MB), an 8MB RAM disk
or a CD-ROM. The host
computer does not require any
special drivers or other
configuration. It just looks like
a new USB drive. You can
transfer files onto the virtual
disk while it is “ejected” and
then “insert” the disk so the host
can see the files. Any files the
host writes to the disk can be
retrieved once the disk is “ejected”.
Access to the files is performed through the web interface. The disk may be inserted from either the web
interface, or the Disk Control menu available via VNC. Most operating systems can “Eject” the disk once it
is inserted, but it can also be ejected from the Web or VNC.

When emulating a floppy disk or RAM disk, the data is stored in RAM on the SV1110IPEXT itself. In
order to emulate a CD-ROM disk drive, a web server is required to provide the CD-ROM image data. The
web server must be accessible to the module, which communicates with it constantly as data is needed.

Floppy mode

Choose the Format as floppy button to switch to floppy mode. Under Windows, the drive will be
identified as a “high density floppy” and will typically be assigned a drive letter of “B:”. The capacity is
limited to 1.44 megabytes in this mode. The purpose of supporting floppy mode is to permit the use of
floppy-disk images generated by other systems. For example, the flash BIOS upgrade process is performed

16

with a special floppy and is bootable. You can transfer bits from that floppy to the SV1110IPEXT (use the
upload disk image form). Now, you can boot from the special floppy. In addition, emergency repair disks
are often restricted to floppies.

RAM disk mode

Choose the Format as
ramdisk button to

switch to RAM disk
mode. This mode is
intended to facilitate
simple data transfer
between the remote user
and the host computer. It
will be recognized by
Windows as an eight
megabyte removable
disk and assigned a drive
letter. You can easily
drag and drop files up to
8MB in size to this
device. In Windows
explorer, you can choose
the “Eject” option to
make the data available
to the remote users.

Reading files from disk

On the File Transfer menu, make sure the disk is “ejected,” then choose the Browse files link. A web page
will be generated that shows the root directory on the disk. You can download files to your browser by
clicking on the file name. It is also possible to delete files and create directories using the buttons provided
on that page.

Disk Formats

When you choose the Format as... button, the disk image stored in RAM is formatted to be an empty MS­DOS disk, with a single file called “Put files here...TXT”. The SV1110IPEXT is able to read most MS­DOS/Windows formatted disks and presents the files via the web interface. However, disk emulation
occurs at the lowest level so that other disk formats can be used, if you have the tools needed to create and
read the disk images. At the bottom of the page are the upload and download options for the entire disk
image. Any image that is exactly 1,474,560 bytes long will be treated as a floppy. Images of other sizes are
supported up to 8MB.

CD-ROM Mode

The SV1110IPEXT does not store any data in this mode. Instead, it emulates a USB CD-ROM drive with a
disk inserted. The data from that disk must be provided by an external web server. You will need a copy of
the CD-ROM contents that you want to emulate as an ISO file. This is a byte-for-byte copy of track one
(the data track) of a data CD-ROM. The ISO file must be made available on a web server which is
accessible by the SV1110IPEXT. To switch to this mode, type in a URL pointing to the ISO image, and
click on Commit. The system will connect to the web server and test the file for access. If successful, you
will be shown a short report on the file contents, and the disk will be ready to use. Currently there is no
other way to preview or browse the contents of the CD-ROM image, except from the host.

17

CD-ROM Web Server Requirements:

• Data must be hosted on a web server that the SV1110IPEXT can access directly, preferably on the

same LAN.

• An image of a bootable CD-ROM disk can be used by the BIOS to boot an operating system.

• The image file itself may be any size, but it will typically be less than 700 megabytes. Normally this

file will be an ISO image (an ISO-9660 file system) but any disk image may be used.

• Web server must support “byte ranges”. Persistent connections are used, if available, as this greatly

improves performance. Read-only access is provided; writing is not supported.

Booting from USB Disk

If the host machine's BIOS supports USB boot devices, it is possible to boot from the emulated CD-ROM
or floppy. This allows complete operating system replacement without touching the computer.

The first step is getting a bootable disk image onto the emulated floppy or CD-ROM. For CD-ROM
images, you will need an ISO image from a disk that contains special bits to enable boot (“El Torito”
standard). Nothing special is needed when reading the ISO from a working, bootable CD-ROM. To create a
bootable floppy, you can format the emulated floppy from the target system, or read the data from a
working boot floppy. This can be done from Windows using “Disk Copy” (right click on the drive letter in
the Windows Explorer) or by using a program like “RAWRITE”.
Once you have a bootable image (CD-ROM or floppy) working on the KVM control over IP module, you
must adjust your BIOS settings to tell it to
boot from a USB device.
NOTE: You must select “USB CD-ROM” as
the boot device for the BIOS, if using a CD­ROM image and “USB Floppy” if using a
floppy image.

BIOS and OS Vendor Support

NOTE: Up-to-date information about OS and BIOS support is listed in the on-line help page of the internal
web server.

Windows 95 or earlier: No USB support.
Windows 98: Keyboard and mouse are supported. Floppy/CD-ROM disk emulation is not supported.
Windows 2000 SP3+: Keyboard and mouse are supported. A bug in versions before Sevice Pack 2

prevents floppy/CD-ROM support from working correctly. (In particular, it appears to work, until you
attempt to transfer files bigger than 4096 bytes). Upgrade to SP3 or later for full disk emulation support.
Windows XP, Windows Server 2003: Keyboard, mouse and disk emulation are supported.
FreeBSD 4.5: Keyboard, CD-ROM tested and working; other features untested.
AMIBIOS (from American Megatends Inc): Keyboard, floppy and CD-ROM emulation work well. It is
possible to boot from virtual CD-ROM or Floppy. You must enable either the USB floppy or CD-ROM as
a boot device (under Advanced Setup) and enable “USB Function for DOS” (under Features Setup).
Award BIOS (from Phoenix Technologies): USB Keyboard works. USB booting is not implemented by
this BIOS, although it is listed in the menus.

NOTE: BIOS firmware is constantly evolving. Contact your computer or BIOS manufacturer for the latest
release of your computer’s BIOS for maximum functionality.

Using the Terminal Interface via Serial Port

The terminal interface you can access via the serial port permits the configuration of the basic settings of
the SV1110IPEXT. While not intended to be a substitute for the Web interface, it does allow you to
configure some of the same functions. The menu list below describes the options that can be modified
through the terminal interface:

Note that you must use the W option to confirm any changes you make before restarting the unit or the
changes will not take effect. There is no restart option available from the command line; power the unit off
and on again manually to restart the unit in the new configuration.

• Web interface: The integrated Web server includes a Java-based VNC client. This allows easy

browser-based remote control.

• Native VNC client: There are several third-party software programs that use the standard VNC

protocol, available in open source and commercial VNC clients.

• SSH access: By default, there is a standard SSH server running on port 22 (the standard SSH port).

Once connected via SSH, the VNC traffic is tunneled through the SSH connection and encrypts the
VNC session. Each method will be discussed briefly in the following section. The type of encryption
method or client used is not critical.

Web Interface

The Java-based VNC client that is
integrated into the
SV1110IPEXT’s interface
requires a browser with cookies
and JavaScript enabled. To start
the Java VNC client, login to the
Web configuration interface and
click on the thumbnail of the
desktop on the Home menu, or
follow one of the two links on that
page:
Java VNC with no encryption
(faster).
Java VNC with SSL encryption
(more secure).

You may need to upgrade your Java support in your browser; however, most modern browsers come with a
version of Java that is compatible with this application.
The Java VNC client makes a connection back to the KVM control over IP module over port 5900 (by
default) or 15900, if encrypted. The encrypted connection is a standard SSL (Secure Socket Layer)
encrypted link that encrypts all data from the session, including the actual video pictures.

Because Java is considered a “safe” programming language, the Java VNC client has some limitations.
Certain special keystrokes cannot be sent, such as “Scroll Lock” or just the CTRL key (with no other key).

This client software requires the use of Java 2 (JRE 1.4) to enable features like wheel mouse support. Sun
Microsystem’s Java site, www.java.com, is an excellent resource to ensure your browser and operating
system is up-to-date.

Native VNC Client

This system implements the VNC protocol, so any off the shelf VNC client can be used. There are over 17
different VNC clients available and they should all work with this system. This system automatically
detects and makes use of certain extensions to the basic RFB protocol that is provided by the better VNC
clients.
The best client currently is TightVNC (www.tightvnc.com). Binaries are available for Windows, Linux,
MacOS and many versions of Unix. Source code for all clients is available there too. This version of VNC
is being actively developed. The authoritative version of VNC is available from RealVNC
(www.realvnc.com). This source base is the original version of VNC, maintained by the original developers
of the standard. For a commercial, supported version of VNC, you should consider TridiaVNC
(www.tridiavnc.com). Their version of VNC is a superset of TightVNC and contains a number of
enhancements for use in a larger corporate environment.

21

NOTE: Some native VNC clients may require a flag or setting indicating they should use BGR233
encoding by default. If this flag is not set, you may see a garbled picture and the client will fail. The Unix
versions of VNC require the flag -bgr233. For examples on using this flag, review the commands in the
following section.

SSH Tunnel (with Native VNC client)

If you are using openssh, here is the appropriate Unix command to use, based on the default settings on a
machine at 10.0.0.34:

ssh -f -l admin -L 15900:127.0.0.1:5900 10.0.0.34 sleep 60

vncviewer -bgr233 127.0.0.1::15900

Same command, but using the WAN port:

ssh -f -l admin -L 15900:127.0.0.1:5900 10.0.0.98 sleep 60

vncviewer -bgr233 127.0.0.1::15900

Notes:

A copy of these commands, with appropriate values filled in for your current system setting, is provided in
the on-line help page. This allows you to “cut-and-paste” the required commands accordingly.
You have 60 seconds to type the second command before the SSH connection will be terminated.
The port number “15900” is arbitrary in the above example and can be any number (1025...65535). It is the
port number used on your client machine to connect your local SSH instance with the VNC client. If you
want to tunnel two or more systems, you will need to use a unique number for each instance on the same
SSH client machine.
Some Unix versions of the VNC client have integrated SSH tunneling support. Some clients require your
local user id to be the same as the userid on the system.
Use a command like this:

vncviewer -bgr233 -tunnel 10.0.0.34:22

Using the VNC Menu

One of the unique features of this product is the VNC menu system. Whenever you see a window with a
dark blue background and grey edges, this window has been inserted into the VNC datastream so that it is
effectively laid over the existing video. These menus allow you to control the many features of the
SV1110IPEXT without resorting to the web interface or a custom client.

Welcome Window

22

When you initially connect to the system, a window similar to the one above will be shown.
This tells you which system you are controlling, what encryption algorithm was used and what key strength
is currently in effect. Click anywhere inside the window to clear it, or wait ten seconds.

Bribar Feature

Along the bottom of the VNC screen is a dark blue bar with various buttons. We call this feature “the
bribar”. Its purpose is to show a number of critical status values and to provide shortcuts to commonly used
features. Here is a snapshot of what it may look like. There will be slight differences based on optional
features and system configuration. Starting from the left side of the Bribar, each feature and its function is
outlined below.

Bandwidth: Indicates current average bandwidth coming out of the KVM control over IP module. The
second number measures round trip time (RTT) of the connection when it was first established.

Resync: Re-aligns the remote and local mouse points so they are on top of each other.
Redraw: Redraws the entire screen contents; occurs immediately.
PS/2: Resets the PS/2 keyboard and mouse emulation. Useful to recover failed mouse and/or keyboard

connections in PS/2 mode.
USB: Resets the USB connection by simulating an unplug and replug. Forces operating system to notice
the USB keyboard, mouse and emulated disk drive.

÷4, ÷8: Switches to thumbnail mode, at indicated size.
Ctrl-Alt-Del: Sends this key sequence to the host. Works immediately.
Alt-F4: Sends the key sequence to host (closes windows).
KVM: Sends the KVM “hotkey” sequence. This function is only enabled when you have configured the

unit to expect a particular brand of KVM downstream. It sends the key sequence to pull-up the KVM's on­screen display (OSD) menu.

Menu: Shows the main menu.
Video: Shows the video-tuning menu where the picture quality can be tuned.
Keys: Shows the VirtKeys menu, which allows you to simulate pressing special keys such as the Windows

key or complex multi-key sequences.

Disk: Shows the USB emulated disk menu.
In/Ej: Insert or eject the emulated USB disk. Enabled only if the host is recognizing the USB disk.
R/W: Shows if the disk image is readable and/or writeable. If the disk is readable, the R letter will be

white. Whenever the host reads from the disk, the R letter will glow green for a few seconds. Whenever the
host is writing to the disk, the W letter will glow for a few seconds.
8M: The type of USB disk selected is indicated here. In this example, it is an eight-megabyte Ramdisk. The
letters Flpy indicate floppy disk and CD indicate emulated CD-ROM.
PS/2: This area will show either PS/2 (as in this example) or USB to indicate if keyboard and mouse are
being emulated via USB connection or PS/2 signals.
[1][A][S]: These flags show the state of the keyboard lights, NumLock, ShiftLock and ScrollLock
respectively.
X: Click this button to close the Bribar and hide it. This can be very useful on a client machine whose
screen-size is the same as the remote machine. No vertical screen space is wasted with the Bribar. Use
double-F7 to start the main menu, then click on Bribar to restore the feature.
Other items. If the server's screen is larger than 1024x768, additional buttons will be shown to the right of
the above listed items. These are all keyboard shortcuts and are duplicated in the Keys menu.

23

Main Menu

To access the main menu, press F7 twice quickly. You must press the key twice within one second. If you
press it once or too slowly, then the F7 key(s) are sent to the host, just like any other key. This is the only
way to get into the menu system, if the Bribar is disabled. Here is the main menu for a typical system:

The main menu window may be moved by clicking and dragging on the title bar. It can be closed by
pressing Escape, or by clicking on the red X in the top right corner.
Here is a guide outlining various fields from the Main Menu. Most of the functions operate immediately.
Other functions require a response to a confirmation prompt first before performing the requested function.
Identification - Fixed text data that is defined by the user from the web interface. Intended as an
organizational aid.

Status: Current status of the attached system and the status of the module.
B/W Min/Avg/Max/Auto: Bandwidth control. The white button is the mode the system is currently

operating. If you choose Min/Avg/Max then you will override the default, Auto. As the automatic mode
measures actual network performance, you may see the current mode switch from Min up to Avg or Max.
The different modes indicate more time spent on compression versus more bandwidth. There is no visual
difference between the modes, but there can be a noticeable difference in speed and smoothness.
Mouse Resync: Resynchronizes the mouse pointer so that the local and remote mouse pointers are on top
of each other.
PS/2 Reset: Resets the PS/2 emulation going to the host and to the attached PS/2 devices. This can be used
if the mouse stops responding or the PS/2 keyboard isn't working.
USB Replug: Simulates unplugging the USB connector and then plugging it back in. If the host is
confused or having trouble with USB, this button may be used to restore it.
Take Control: When multiple users are connected to the same system, use this button to take control away
from another user. Only one user may control the keyboard and mouse at any time. All users see the same
picture.
Thumbnails: Switch to smaller thumbnail size screen images (click anywhere on thumbnail to restore it).
Each button corresponds to a different sized image, from half size to one-sixteenth.

24

Logout: End the VNC login session and disconnect.
Video Tuning: Sub-menu with video adjustments, to be used when automatic picture adjust does not

provide a good quality picture. (See section below.)
VirtKeys: Virtual keyboard provides a menu with special keys that are often hard to generate but needed
by the remote system. The most common key sequence is the “Control - Alt - Delete”. (See section below.)
Disk Ctrl: Emulated USB disk control submenu. Shows status of floppy/Ramdisk or CD-ROM and permits
easy “insertion” or “eject”. (See section below.)
KVM Menu: Simply generates the key sequence Scroll Lock and Scroll Lock-Space. This sequence is
used to startup the on-screen menu for a number of enterprise-class KVM switches. When these
conventional KVM switches are combined with the KVM control over IP module, this key makes
accessing their built-in menu easier, especially from the Java client, which does not support the Scroll Lock
key. This button will only be shown when an external KVM has been enabled via the web interface.

Bribar: Closes or reopens the Bribar window along the bottom of the screen.

VirtKeys Menu

Here is a snapshot of the Virtual Keys window.

Clicking any button in the top half of the window simulates pressing and releasing the indicated key. In the bottom area
of the screen, clicking will simulate the indicated Meta key being pressed. You may then click in the top part to send
another key and release the Meta key at the same time. Alternatively, you may move the mouse outside this window,
press the regular key, and then choose -RESET- to release all depressed keys.
The VirtKeys menu can be left open while using the host system. You can then click the required button at the suitable
time, and still interact with the host in a normal fashion.

Examples:

• Ctrl-Alt-F4: Use L-Ctrl then L-Alt in the Toggles area. Then click F4.

• To bring up the Start menu under Windows: Click the L-Windows button at the top left of the above

window.

25

Video Tuning Menu

This menu is used to fine-tune the video picture.

Use the Auto Everything button to automatically fine-tune all three adjustments. If the test pattern for
Color Offset calibration is not present on the screen, then the Color Offset adjustment is skipped.

Changes/frame indicates the number of 16x16 blocks of video that are being sent, on average, for every
frame of video. With a static image being displayed by the server, this number should be zero (shown as ­nil-). Moving the mouse, for example, will cause the number to jump to about 2 or 3. You may use this
number to judge the picture quality as you adjust the controls on this menu.

Picture Positioning affects the image position on your screen. If you see a black line on either side of your
screen, or at the top or bottom, you can use the arrow buttons to shift the image in that direction. Pressing
Auto does the same thing for you automatically. Use Save to save the changes you have made manually.
Since this adjustment depends on the video mode, separate values are stored for each video mode.

Color Offset is a fine tuning adjustment that requires the use of a test pattern. There is a copy of the test
pattern available on the Help! menu of the integrated web server. You must arrange for that image to be
shown on the host computer. Do not allow scaling, cropping or any other changes to that image. Press the
Auto button and the system will calibrate color for the best possible picture in approximately one minute. If
the system cannot find the test pattern on the screen, it will say so. Check that the pattern isn't scaled or
covered up. It's important to do this operation in 24-bit or 32-bit color video mode (i.e. truecolor). Although
the algorithm may work in 16-bit or 8-bit color video modes, the results will not be optimum and usually it
won't be able to find the test pattern.

Sampling Phase does not normally need to be used since our system tunes the sampling phase whenever
the video mode changes. This button does not require a test pattern, but will perform optimally when used
with our standard test pattern. For your reference, the sampling phase number is shown to the right of the
Filtering button.

Noise Filter controls the advanced video filtering of our system. Unlike other filtering algorithms, our
noise filter will only remove noise. It does not degrade the signal quality or readability of small text. You
may turn it on and off using the indicated button, or set it to other values using the arrows. Higher numbers
cause more filtering and may cause artifacts when moving windows. The most common visual artifact is a

26

vertical line dropping when moving windows horizontally. You may use the Redraw button to correct these,
or use a lower filter number. At minimum, these values must be greater than two.

Disk Control Menu

Here is a picture of the Disk Control Menu, while using a CD-ROM image:

Aside from status information, there are only three buttons in this window. Insert and Eject will simulate
that action, and only one option is enabled at any time, based on the current state of the emulated disk.
USB Replug can be used to force the host to recognize the disk. It is not needed unless the host OS or
hardware is does not recognize it automatically.

27

Getting Peak Performance

Choose the best video mode

We recommend using 60Hz refresh rate and 1024x768 resolution. Using a smaller resolution like this
allows you to fit multiple windows on your remote desktop. Higher refresh rates stress the video card's
quality and do not provide any additional information or benefit.

Noisy video cards

• A digital KVM works by converting the analog video signals emitted by your video card into digital

data. If there is noise on that signal, then it must be digitized and sent over the network too. The name
brand, quality video cards have, in our experience, better performance simply because they don't add
analog noise.

• Some external KVM switches generate video noise too. Try to keep cables short to reduce the effect.

• Enable the Noise Filter option (on the Video Tuning menu) to mitigate noise issues.

Network performance

• The SV1110IPEXT will always send as much data as it can, given what's happening on the screen and

the actual network performance. When nothing is changing on the video screen, zero bytes are sent
over the network. If the whole screen is changing, then the module will send as much data as your
network connection and VNC client can handle while not allowing it to fall behind.

• Network latency, which is the total time it takes for a packet to get to the SV1110IPEXT and come

back, has the biggest impact on perceived performance and usability. Network bandwidth has a lesser
effect, particular when just moving the mouse around. Only a few bytes need to be sent when the
mouse is moving (and nothing else is changing on the screen), but the round-trip-time limits the hand­eye coordination of the user if it is too great. Both actual bandwidth and measured network latency are
shown in the Main Menu.

28

USING YOUR KVM SWITCH

SV831D, SV1631D

Cascade Configuration

To can connect a second level of KVMs to one or more of your KVM switch’s PC ports. There is one
Master KVM switch, the switch connected to the KVM Control Over IP Console. The KVM switches
connected to the Master switch are know as Slaves. Once connected, KVM switches configure themselves
as either Masters or Slaves. You can only connect an equal or “smaller” KVM to the Master KVM. For
example, a 16-port Master KVM switch can have both 16-port and 8-port slaves. An 8-port Master KVM
switch can only have 8-port KVM slaves or lower.

The 8-port KVM can support 64 PCs, with 8 8-port Slaves KVMs, each connected to 8 PCs. The 16-port
KVM can support 136 computers, with 8 16-port Slave KVMs, each connected to 16 computers.

To cascade your KVMs, connect one of your Master switch’s PC port to the Slave switch’s Console port.
When turning on your cascaded switches, turn on the Master switch before turning on any of the others.

Optional Rack Mount Accessories

Attach the rackmount brackets to the KVM Switch as shown below.

Assemble the rack cable support then screw it to the back and inside the rack cabinet vertical post.

29

Operating Your KVM Switch

To toggle between computers, you can use the hot-key commands, OSD (On-Screen Display) menu or by
using the pushbuttons. If you are operating your PCs remotely, you will likely be using the hot-key
commands or the OSD.

Push Buttons

The LEDs on the KVM switch indicate which computers are turned on (green) and which computer is
selected (red). The indicator flashes red when in Auto or Manual Scan mode. You can press any of the
corresponding pushbuttons to select the active computer.

The K/M Reset function reconfigures your system without powering down your computers or your KVM
switch. To reset the switch, press the front-panel 1 and 2 buttons simultaneously.

The Auto-Scan function automatically scrolls through your connected computers. Press the front-panel 7
and 8 buttons simultaneously to enter Auto Scan mode.

OSD Operations

By hitting the left <CTRL> key twice within two seconds, you may see the 'Hotkey Menu' if it is enabled
(an OSD option). Or, by hitting the left <CTRL> key three times within two seconds, you will see a 'KVM
MENU' screen showing a list of the computers with corresponding channel addresses, names and status.

30

The channel address of the currently selected computer is displayed in red, same as the front indicator, to
the right of the OSD title 'KVM MENU'. The color of a device name is green if it has power and is ready
for selection (its corresponding front panel indicator is green), or the color is white as it has no power. OSD
menu updates the color when it is activated. Use the <UP> and <DOWN> arrow keys to highlight a
computer and the <ENTER> key to select it. Or, you may press <ESCAPE> to exit OSD and remove the
OSD menu from the display; the status window returns to the display and indicates the currently selected
computer or operating status.

A triangle mark to the right of a name indicates the port is cascaded to a Slave; the number at the left of the
triangle mark shows the number of ports the Slave has, i.e. 8 for SV831D. <ENTER> key brings you one
level down and another screen pops up listing the names of the computers on that Slave. The name of the
Slave will be shown at the upper right corner of the OSD menu. It is useful to group computers and still be
able to see the group name.

An eye mark to the right of a name indicating the computer is selected to be monitored in Scan mode. In
OSD, this mark can be switched on or off by function key <F2>.

Press <ESCAPE> key to exit OSD and to return to the selected computer; the computer name is also shown
on the screen.

Function key <F1>

To edit name entry of a computer or a Slave. First, use the <UP> and <DOWN> arrow keys to highlight a
channel then press <F1> followed by name entry. Valid characters are A to Z, 0 to 9, and the dash
character. Lowercase letters are converted to uppercase ones. Press <BACKSPACE> to delete a letter one
at a time. Non-volatile memory stores all name entries until you change, even if the unit is powered down.

Function key <F2>

To switch the eye mark of a computer on or off. First, use the <UP> and <DOWN> arrow keys to highlight
it, then press <F2> to switch its eye mark on or off. If Scan Type is Ready PC + Eye, only the power-on
and eye mark selected computers will be displayed sequentially in Scan mode.

Function key <F3>

To lock a device (a computer or a Slave) from unauthorized access, use Security. Security is effective for
only one device (a computer or a Slave). To lock a device, use the <UP> and <DOWN> arrow keys to
highlight it, then press <F3>. Now, enter up to 4 characters (A to Z, 0 to 9, dash) followed by <ENTER>
as new password. A Security-enabled device is marked with a lock following its channel number. To
permanently disable the security function from a locked device, highlight it, press <F3> then enter the
password.

If you want to access the locked device temporarily, simply highlight it and press <ENTER>, the OSD will
ask you for the password. After entering correct password, you are allowed to use the device. This device is
automatically re-locked once you switch to another one. During Scan mode, OSD skips the security­enabled device.

NOTE: Only one device (a computer or a Slave) can be locked by this function at a time.

If you forget the password, the only way to permanently disable the security function is to remove all
possible power sources from the master StarView. You need to turn off all computers and unplug all power
adapters, then restart everything

31

Function key <F4>

More functions are available by hitting <F4>. A new screen pops up displaying more functions as
described below. Most of them are marked with a triangle indicating there are options to choose from.
Using the <UP> and <DOWN> arrow keys, select the functions and press <ENTER>. Available options
will be shown in the middle of the screen. Again, using the <UP> and <DOWN> arrow keys to view
options then press <ENTER> to select it. You can press <ESCAPE> to exit at any time.

Auto Scan

In this mode, the StarView automatically switches from one power-on computer to the next
sequentially in a fixed interval. During Auto Scan mode, the OSD displays the name of the selected
computer. When Auto Scan detects any keyboard or mouse activity, it suspends the scanning until
activity stops; it then resumes with the next computer in sequence. To abort the Auto Scan mode, press
the left <CTRL> twice, or, press any front button. Scan Type and Scan Rate set the scan pattern. Scan

Type (<F4>: More\Scan Type) determines if scanned computers must also be eye mark selected. Scan
Rate (<F4>: More\Scan Rate) sets the display interval when a computer is selected before selecting the

next one.

Manual Scan

Scan through power-on computers one by one by keyboard control. Scan Type (<F4>: More\Scan
Type) determines if scanned computers must also be eye mark selected. Press the up arrow key to
select the previous computer and the down arrow key to select the next computer. Press any other key
to abort the Manual Scan mode.

Audio Stick

An optional multimedia module can be LINKed to the back of each StarView for selecting microphone
and stereo speaker signals. There are two options for Audio Stick: ON and Off. When set to On, audio
selection follows computer selection. When set to Off, audio selection stops following computer
selection. It is useful if you want to listen to a particular computer's audio signal while operating other
computers. The non-volatile memory stores the Audio Stick setting.

Hot Key Commands

A hot key command is a short keyboard sequence to select a computer, activate a computer scan, etc. A
hot-key sequence starts with two Left Control keystrokes followed by one or two more keystrokes. A
built-in buzzer generates a high-pitched beep for correct hot-key sequences and a low-pitched beep for
errors or bad key combinations that will not be carried out.

The short form hot-key menu can be turned on as an OSD function (<F4>: more\Hotkey Menu) every time
the left <CTRL> key is pressed twice.

L-CTRL: is the <CTRL> key located at the left side of the keyboard.
1~8/A~H: are the number keys 1 ~ 8 at the upper row of the keyboard and character keys A ~ H case

insensitive.

Do not use the keypad at the right of the keyboard.

Selecting a Computer

To select a computer by hot-key command, you must know its channel address, which is determined by the
StarView connection. For a computer connected to a Master, its address is represented by the PC port label
(1~8 or A~H). For a computer connected to a Slave, two characters represent its address. The first
character is the channel address of the Master unit (1~8) and the second one is the channel address of the
Slave (1~8 or A~H). Please note that only Master's 'PC 1' ~'PC 8' ports can be connected to a Slave.

left Ctrl + left Ctrl + 7 selects a computer connected to port 7 of the Master.

left Ctrl + left Ctrl + 6 + C selects a computer connected to port C of a Slave connected to port 6

of the Master.

Auto Scan

To start Auto Scan, automatically scan power-on computers one by one at a fixed interval:

left Ctrl + left Ctrl + F1

When Auto Scan detects any keyboard or mouse activity, it suspends the scanning till activity stops; it then
resumes with the next computer in sequence. The length of the Auto Scan interval (Scan Rate) is adjustable.
To abort the Auto Scan mode, press the left Ctrl key twice.

Note: Scan Type determines whether eye mark is necessary during Auto Scan.

Manual Scan enables you to manually switch back and forth between power-on computers.

left Ctrl + left Ctrl + F2

Press the up or down arrow to select the previous or the next computer in sequence. And, press any other
key to abort the Manual Scan.
Note: Scan Type determines whether eye mark is necessary during Manual Scan.
To adjust Scan Rate which sets the duration before switching to the next computer in Auto Scan:

33

left Ctrl + left Ctrl + F3

The StarView sends one to four beeps indicating scan interval of 3, 8, 15 and 30 seconds respectively.

To adjust keyboard typematic rate (characters/sec), this setting over-rides that of BIOS and any operating
system:

left Ctrl + left Ctrl + F4

The StarView generates 1 to 4 beeps corresponding to 10, 15, 20 and 30 characters/sec respectively.

Audio Stick

An optional multimedia module can be LINKed to the back of each StarView for selecting microphone and
stereo speaker signals. There are two options for Audio Stick: On and Off. When set to On, audio selection
follows computer selection. When set to Off, audio selection stops following computer selection. It is
useful if you want to listen to a particular computer's audio signal while operating other computers.

left Ctrl + left Ctrl + F5

The StarView generates 1 or 2 beeps corresponding to On and Off respectively.

34

Troubleshooting

If you are experiencing trouble with your devices, first make sure that all cables are connected to their
proper ports and are firmly seated. You may also want to try resetting the devices by removing and
reconnecting the AC Adapter (SV1110IPEXT) or the KVM Reset button (SV831D, SV1631D). If
problems persist, you can do a full reset of the SV1110IPEXT by using the rest to factory setting from the
serial terminal interface menu. Using the factory restore button will delete all your configurations and
restore the device back to the factory defaults. You will have to go through the initial setup procedure
again.

Video response is slow to respond or erratic.

• Verify that the managed host computer video configuration is set to a supported resolution and

refresh rate. Optimum video resolution is 1024 x 768 @ 75Hz. For a list of supported video
resolutions and refresh rates, see the Technical Specifications.

Video displays pink screen.

• Verify that the managed host computer is turned on.

• Verify that the video refresh rate on the managed host is set to 85Hz or lower.

• Re-establish video communication using power-on reset.

• Reboot the managed host computer as needed.

Mouse pointer or mouse buttons slow to respond or erratic.

• Re-sync the mouse using the left-click or moving it across the screen several times (for at least five

seconds).

Mouse pointer is out of sync with local mouse “dot.”

• Verify that the managed host computer mouse acceleration is turned off. See “Mouse Acceleration.”

Can’t communicate with the SV1110IPEXT after power-on reset or new installation.

• Wait 10 seconds after resetting before attempting to access the device.

• Ensure that the correct IP address has been entered in the browser.

• If you have performed a “factory default restore,” the IP address has been reset to 192.168.1.254.

• If you are operating behind a firewall, make sure that all the appropriate ports have been opened.

No OSD screen.

• Make sure monitor cables are firmly connected.

• Make sure you are using a Multisync monitor.

Master/Slave does not work or there is a double OSD.

• Make sure that the slave’s Console port is connected to one of the Master’s PC ports.

• Perform a KVM Reset.

The Up and Down arrows don’t work in manual scan mode.

• Check the Scan Type (from the OSD menu) and make sure you have selected the proper computers.

Auto Scan does not work, the StarView beeps and the indicators flash red

• Make sure more than one computer is turned on. Auto Scan only works with powered on computers.

• Check the Scan Type (from the OSD menu) and make sure you have selected the proper computers.

• Press the Left Control key twice to abort the Auto Scan.

35

OSD menu is not in the proper position.

• The OSD menu has a fixed resolution and its size varies depending on the monitor. Use <F4> More/

Position (from the OSD menu) to move the OSD menu to a different location.

Cannot select a computer connected to a Slave.

• Make sure that the Slave’s Console port is connected to one of the Master’s PC ports.

• Only ports PC1 to PC8 can be connected to Slaves, even if the Master KVM has 16 PC ports.

• Only one level of Slave KVMs is allowed.

Forgotten master password. (SV1110IPEXT)
You can reset the master password using the serial interface on the module. Use the `S' command, and type
a new password. The old password is not required for this procedure.

Remote mouse and local mouse don't line up. (SV1110IPEXT)
Use the “mouse resync” command in the main menu or press the “Resync “ button on the Bribar. If the
mouse pointers still don't line up, verify that mouse acceleration has been disabled.
NOTE: The Windows login screen does not accept the “mouse acceleration” configuration, and always has
the mouse accelerated regardless of your configuration. Therefore, on this screen it is best to avoid using
the mouse.

After resync, mouse is still a little bit off. (SV1110IPEXT)
Use the video adjust menu to position your video image exactly where it should be. Normally a slight video
positioning error is perceived as a mouse sync issue. A video positioning error is visible as a black line
along the top or bottom (and right or left) edges of the remote screen. Remember to save your position

changes!

Cannot login via SSH. (SV1110IPEXT)
Remember to use either “admin” or a username created in the system as the user name you give your SSH
client. If you see a warning about “identity of host cannot be verified”, and a question about saving the
host's fingerprint, this is normal for the first time you connect to any machine running SSH. You should
answer “yes” so that your SSH client saves the public key of this host and doesn't re-issue this warning.

Certificate warning shown when connecting via HTTPS. (SV1110IPEXT)
It is normal for a warning dialog to be shown when connecting via HTTPS. The SSL certificate we use is
created when the unit is first produced. It does not contain the correct hostname (subject name) because you
can change the hostname as required. Also, it is not signed by a recognized certificate authority (CA) but is
signed by our own signing authority. For more details, refer to Appendix A, “About Security Certificate
Warnings”.

Don't set LAN and WAN to the same IP Address. (SV1110IPEXT)
It doesn't work. If you want to use both ports in redundant mode, enable the Ethernet bridging option and
plug both into the same network. The WAN IP address is not used in that configuration.

Appendix A: About Security Certificate Warnings

What is a security certificate?

Sites that employ secure TCP/IP (Internet) connections include a certificate that confirms that users are
connecting to a legitimate site and are not being redirected without their knowledge. Certificates are issued
by trusted third parties called Certificate Authorities (CAs) and contain essential details about a site that
must match the information supplied to your Web browser.

Why do I receive a warning when I access the login screen on the SV1110IPEXT?

As it redirects to a secure (SSL) session by default, the login screen may generate a warning from your
Web browser or the VNC Java client for two different reasons. First, the CA that has issued the certificate
on StarTech.com’s behalf may not yet be recognized as a trusted source by the computer you are using to
access the SV1100IPEXT. Second, since the unit could be configured in a number different ways, it is
impossible to supply a generic certificate that will match your exact network settings.

Is my data safe?

Yes. The security certificate does not affect encryption effectiveness in any way, nor does it make the
SV1110IPEXT any more vulnerable to outside attacks.

Can I prevent the warning from occurring?

Yes. You have two options that may prevent the warning from occurring. First, if the Web browser you
are using offers the option to ignore the warning for future visits, the browser will no longer generate a
warning if that option is selected. Second, if you install the certificate from the SV1110IPEXT onto the
host computer (see below) and if the unit is configured with a domain name ending in .com, .net, .org, .gov,
.edu, .us, .ca, .uk, .jp, or .tw (i.e. remotecontrol.mydomain.net) then the warning should no longer occur.

Installing the new certificate…
The following is a demonstration of how to install the certificate from the SV1110IPEXT onto your local
computer.

1. Open your Web browser and go to the SV1110IPEXT login screen. Click the update security

certificate link.

2. When prompted, choose Open.

3. A Window will appear that offers information about the certificate. Click Install Certificate.

4. The Certificate Import Wizard will appear. Select Automatically select the certificate store…

(default) and click Next. When the next window appears, click Finish.

5. A confirmation dialog will appear asking you if you wish to install the certificate. Click Yes.

6. A message should appear saying the import was successful. Click OK.
