Disabling Mouse Acceleration on the Host Computer

Many operating systems offer a feature called mouse acceleration, allowing the user to
adjust the responsiveness of the cursor on the screen in relation to physical movements
of the mouse. While this is usually a beneficial interface enhancement, it can interfere
with the operation of the KVM Remote Control and should be disabled on the host
computer before a remote session is attempted. Follow the instructions below to disable
mouse acceleration for the operating system installed on the host computer.

Configuring SVxx41HDIE

SVxx41HDIE offers four distinct methods for configuring the unit for your network. Which
method will work best will depend on your level of experience and your specific network
configuration.

Please note

below can result in system instability. Please refrain from connecting the remote
computers, until the local peripherals have been connected.

Web Configuration Using the On-Screen Display

Upon boot-up, including following a reset, SVxx41HDIE will display a window on the local
video output (front VGA connector), that will appear as follows:

Assigned IP Address

The initial screen will display the IP address assigned by your existing DHCP server (if
present on your network). If no DHCP server is detected, a factory assigned IP address
will be displayed in its place (10.0.0.15 by default). Please make note of the assigned IP
address, as you will need to enter it into your web browser to access the Web Interface.

key.

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 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 image, but should supply (at minimum) three essential details:

address,MAC address

, and device (or machine) name for the computers and other

IP

devices connected to your network. The values for the SVxx41HDIE tested above are as
follows:

IP Address:
MAC Address:
Device Name:

192.168.22.4
00-0E-C5-00-08-1A

(none)

Instruction

Manual

7

The easiest way to identify your SVxx41HDIE 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 SVxx41HDIE. 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.

NOTE:

with the Web configuration, do not power off the unit or your DHCP server, since the
Server Remote Control might lease a different IP address. Should this happen, re­examine the DHCP log to verify the IP address again.

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 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 (i.e. 192.168.1.100). For details on how to change the IP address of your
computer (if necessary), consult your documentation or System Administrator for
assistance.

NOTE:

same IP address as the SVxx41HDIE 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:

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 SVxx41HDIE, you can use
the IP address 192.168.1.123 to access the Web configuration system.

Once you have located the IP address of the SVxx41HDIE and wish to proceed

It is advisable to verify whether another device on your network is using the

Terminal Configuration Using a Serial Cable

Configuring the SVxx41HDIE using a serial cable is the best choice if you need to pre­configure 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 preferable because of its intuitive
interface and the fact that you do not have to be within close physical proximity to
perform the configuration. However, if you wish to use the serial cable method to
configure the SVxx41HDIE, you can use any typical communication software package

UNIX:

(
You can use the serial port on the SVxx41HDIE to access the terminal configuration tool;

to do so, you will require a null modem serial cable. Connect a female end of a serial
cable to the serial port used for serial access on the host computer. Connect the
opposite end to the SVxx41HDIE. Configure the terminal software with “8N1” settings:

tip, cu, kermit, minicom;

Windows:

HyperTerminal, kermit).

Using the Web Interface

The Web interface is the most intuitive way to configure the SVxx41HDIE. Offering a
Java-based VNC client that can be used to control the host computer from a remote
location, as well as support for any industry-standard HTML Web browser. You can
access the Web interface by opening your Web browser and entering the IP address of
the SVxx41HDIE you wish to access/configure. The IP address will be eithera)the
address assigned by your DHCP server as identified in the previous section, or

192.168.1.123 if your network uses static IP addressing.

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 SVxx41HDIE. 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 theWoption to confirm and apply any changes made before you
exit the terminal session.

Accessing the VNC Interface

There are three ways to communicate with the Server Remote Control unit in order to
control the host computer:

Web interface:

•

allows easy browser-based remote control.

Native VNC client:

•

standard VNC protocol, available in open source and commercial VNC clients.

SSH access:

•

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

Using SVxx41HDIE’s web 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

You may need to upgrade 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 Server Remote Control unit 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 JavaVNC client has
some limitations. Certain special keystrokes cannot be sent, such as “Scroll Lock” on the
keyboard.

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

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.
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

Getting Peak Performance

• 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 also be digitized and sent
over the network. Quality video cards, in our experience, offer better performance
simply because they don't add analog noise.

• Some external KVM switches generate video noise as well. Try to keep cables short, in

order to reduce this effect.

Network performance

• The SVxx41HDIE 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 unit will send as much data as your network connection and VNC client allow.

• Network latency, which is the total time it takes for a packet to get to the SVxx41HDIE

and come back, has the biggest impact on perceived performance and usability.
Network bandwidth has a lesser effect, particularly 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 hand-eye coordination of
the user if it is too great. Both actual bandwidth and measured network latency are
shown in the

Using the Modem feature

Background

The modem feature allows the SVxx41HDIE to act as an Internet connection server for
increased security and flexibility in connecting with the host computer. Unlike the TCP/IP
connection used with the standard Web configuration and VNC clients, the modem
creates a one-to-one connection between the SVxx41HDIE and the computer you are
using to manage the host computer that is essentially private, as it bypasses the public
Internet completely.
connection protocols are supported) and a dedicated phone line that can be connected
to the modem for external access. While it is possible to use the modem feature through
some PBX systems, this increases the complexity and reduces the performance of the
connection. For clarity, the instructions presented here assume that the modem is
connected to a typical POTS (plain old telephone system) line that is not routed through
a phone management system or shared with other devices. If you wish to use this
feature through a PBX system, it may require some experimentation and additional
support from your telecom services provider, and is not supported by StarTech.com.

Connecting a Modem

Modem Connection

Note:

this feature requires both an external modem (most standard

The SVxx41HDIE will work with virtually any Hayes-compatible modem that recognizes
the standard AT command set. Some modem manufacturers offer “enterprise” grade
modem products (at a premium price) that include technology to improve the stability of
connections; whether this type of product would be beneficial to your application depends
on whether you consider the modem connection to be mission-critical, the quality of your
telecom infrastructure, and your budget for implementing this solution. The model of
modem attached is essentially transparent to the SVxx41HDIE.

It is important to note that modems that offer “56K” (or 56,000 bps) connections often
achieve connection speeds that are far lower than their maximum capabilities. Given the
limitations of telecom infrastructure (many locations have yet to implement fully digital
switching technology, and still rely on older analog technology for some segments), the
maximum “upstream” transfer rate is limited to a maximum of 33,600 bps between two
modems; the “downstream” rate is often within a similar range for a typical connection.
Therefore, speeds below 56,000 bps do not indicate a problem with the modem or the
SVxx41HDIE, but simply reflect the line conditions at the time the connection is made.

The Serial port can be used for serial port configuration when the modem is connected.
It requires the use of a null modem serial cable.

female serial connection. Connect that end of the cable to the Serial connection on the
rear panel of the SVxx41HDIE.

Modem configuration

Although most connections will work appropriately with the default settings on
SVxx41HDIE, manual changes can be made. To do so:

Login to the Web interface as

following changes to enable and configure the modem connection.

Enable modem connections (PPP) via serial port/modem:

•

Baud rate to use (affects connection between us and the modem only):

•

115200.

Init string:

•
The baud rate dictates the connection speed between the SVxx41HDIE’s serial port and

the modem, and does not affect the connection speed between the local and remote
modems, as they will negotiate their own connection speed when a connection is made.
It is highly recommended that this setting be left at the default for best performance.

The initialization (“init”) string is the command (using the standardized Hayes AT
command set) that the SVxx41HDIE will send to the modem to activate it. The string
included should work with the majority of modems and configures the following
connection properties: answer incoming calls on the first ring, enable hardware flow
control, and lock the connection speed. Your modem’s documentation will describe other
potential init strings that you can use to alter the connection properties. For instance,
you could commit the settings to the modem’s non-volatile memory (NVRAM) or allow
the modem to adjust the connection speed for greater stability (and so on). You may
wish to test the connection with the default init string first, before making changes
specific to your modem model or situation, to simplify the troubleshooting process.

Accessing the Web Interface

Once a dial-up connection has been established, you can access the Web interface or
start a VNC session using the following IP address:

https://99.99.99.99

You can now login to the Web interface (and/or VNC session) normally. Note that the
remote machine (the one you dialed from) is automatically assigned the IP address

99.99.99.100 for the PPP session. This, and the IP address of the SVxx41HDIE, cannot
be modified. The following TCP/IP port numbers are assigned for a PPP connection,
regardless of the settings configured in the Web interface for the LAN or WAN ports:

HTTPS:
VNC (clear-text):
VNC (SSL secured):

• Some areas of the screen may not be updated as frequently as others, and animations
or other auto-updating areas of the screen may appear out-of-focus or “blocky” as a

• It may be beneficial to minimize any unnecessary icons, backgrounds, or other clutter
on the host computer’s desktop to make the dial-up connection as efficient as possible.

• If you need to configure the device over a serial connection while the modem option is
enabled, connect a serial cable (see immediately above for instructions on what type of
cable to use for the port you are accessing on the SVxx41HDIE) and begin a terminal
session following the instructions under

Using the integrated
using a specialized daisy-chain technology. The SVxx41HDIE includes integrated control
functionality that allows you to monitor and configure serial devices using the interactive
Web interface. To minimize space and infrastructure requirements, the R-Port modules
use a single cable to carry both power and the data signal. All configuration settings are
stored separately in each attached device in non-volatile memory so that they will not be
lost in the event of a power outage or disconnection.

Connecting Serial Remote Control Modules to the SVxx41HDIE

The cable for each serial device is similar to a phone cable and uses an RJ-14

connector. For the first module, connect the cable (provided) to the

panel of the SVxx41HDIE. Connect the opposite end to the

the Serial Remote Control unit. Note that some devices may use an integrated cable, so

you will not need to make a separate connection on the serial device. Once you have

added the first serial device to the SVxx41HDIE, you can connect additional modules to

Advanced Configuration Using the Integrated SSH Shell

In most cases, configuring the SVxx41HDIE to the same settings as the R-Port devices
you are connecting should allow the devices to work with a minimum amount of
configuration. However, you can also change the default settings on each R-Port device
to fit your preferences and the needs of your application.

If you click the

button next to the device you want to configure, two new
windows will appear. The smaller of the two is a login screen; the other is a SSH
terminal window. Click the login window and sign in as

You are now connected to the R-Port module in a live terminal session. Commands you
type will be echoed on the terminal screen. The module also offers a simple menu
system that allows you to change its configuration settings (similar to the function of the
menus in a terminal software package). Press

[Ctrl]-[Shift]–[_]

Operating Notes

• If the power supply to the R-Port modules you have connected becomes faulty (short,

overload) then the R-Port LED on the front panel of the SVxx41HDIE will show red.
Under normal operations, this light should remain green. The R-Port connector on the
rear panel also has an LED that mirrors the status of the light on the front panel.
(Note: The rear LED status was reversed on some early units, where red=normal and
green=fault. This does not affect operation in any way, but a green LED on the front
panel and a red LED on the rear panel indicates that you have one of these units.)

• Hardware handshaking (CTS/RTS) is required for speeds exceeding 9600 bps. It is

enabled by default on the SVxx41HDIE, but may need to be enabled on the other end
of the connection. For Unix systems, the command is:

stty –crtscts < /dev/[serial port]

• A maximum of four users may simultaneously login to the same module. All users may

type commands at any time, and all users will see the same output. Note the following:

• All users have equal access to all channels.

• A maximum of 16 R-Port modules may be connected at any one time.

• You plug-in and unplug any R-Port module at any time. When reconnected, it
will automatically become available after a 15 second initialization period. Any
log entries will be retained by the R-Port module while deactivated, but will not
be available to users until it is re-initialized.

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 SVxx41HDIE?

As it redirects you 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
SVxx41HDIE. 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 SVxx41HDIE any more vulnerable to outside attacks.

Instruction

Manual

35

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 SVxx41HDIE 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 instructions detail how to install the certificate from the SVxx41HDIE onto
your local computer (in this case, when using Internet Explorer with Windows XP).

Certificate warning shown when connecting via HTTPS.

It is normal for a warning dialog to be shown when connecting via HTTPS.The SSL
certificate SVxx41HDIE uses is created when the unit is first produced. It does not

required. Also, it is not signed by a recognized certificate authority (CA) but is signed by
our own signing authority.
