2: Overview
Lantronix Spider and SpiderDuo distributed KVM-over-IP devices are designed to remotely and
securely provide monitoring and control of one target computer system by one or more remote
users. The remote user (client) accesses the Spider or SpiderDuo device over a local or wide area
network connection using a standard web browser.
Spider and/or SpiderDuo device is an evolution of the traditional remote KVM device into a
compact package. It is light enough to be cable-supported from the back of a server and takes up
no rack space.
Both devices differ from other KVM-over-IP devices in several ways. Unlike rack mounted KVM-
over-IP devices, the allocation of one Spider device per computer allows add-as-you-grow
scalability and guarantees non-blocked BIOS-level access to mission-critical servers regardless of
the number of remote users or servers that need access.
This chapter contains the following sections:
Spider Overview
SpiderDuo Overview
Product Information Label
Note: The terms Remote Console and KVM Console are synonymous and used
interchangeably throughout the User Guide.
Spider Overview
The Spider device features, functionality, system configuration and cables, and technical
specifications are described in the following sections:
Features
Functionality
System Configuration and Cables
Technical Specifications
Features
The Spider device is unique in that it is low-enough in power consumption to be powered from the
attached server. The color-coded cable plugs for the keyboard, mouse, USB port and video are
designed to plug directly into the target server. An optional external AC/DC power supply is
available.
It uses Lantronix SwitchPort+ technology to incorporate two hardware-switched Ethernet ports,
one for the primary network connection and the second for daisy-chaining Spider devices, or
aggregating other Ethernet connections (for example, a dedicated management LAN port on the
controlled system). This provides a cost-effective solution in environments in which numerous
cable drops and distance limitations are challenging when adding servers.
The Spider device comes in the following four models:
One model with both PS/2 and USB keyboard and mouse interfaces (software selectable)
One model for USB-only systems
2: Overview
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 17
One model with cable length of 21”
One model with cable length of 58”
Secure, full BIOS-level control of remote servers over an IP network
Space–saving “zero footprint” package attaches directly to the server that saves rack space
Flexible 1–port design allows growth
Guaranteed non-blocked access to remote servers that ensures lowest “cost-per-remote user”
Browser–based, no client software or special licensing required
Virtual Media support allows local drive (floppy, CD, hard drive, USB stick) sharing with a
remote server or remote installation of an OS from an .ISO image
Direct KVM minimizes the number of clicks to the remote–server console
Built-in RS-232 serial port that can be configured for serial console pass-through or remote
dial-in access
Ideal for distributed IT system environments such as small branch offices, campuses, test
labs, and server hosting environments
Server-powered design - no external power supply required
Lantronix SwitchPort+ technology allows Spider devices to be cascaded or share a host
Ethernet connection
Functionality
The Spider device captures the video output from the attached computer, compresses and sends
it over the network to a Java KVM console window launched by the browser or to a command line
interface on the user system, which displays a replica of the server video output on the user
monitor.
The Spider device also uses Java KVM coaxnsole to accept keystrokes and mouse movements
on the user system; recognizes those intended for the target computer; transmits the keystrokes
and mouse movements; and emulates a physically attached keyboard and mouse.
Note: The Spider device supports up to 1600 x 1200 resolution at 60 Hz if its hardware
revision is G22, G23, E21 or higher. If the Spider device hardware is an earlier revision, it
will only support resolutions up to 1280 x 1024 at 60 Hz. The hardware revision number
can be found on the Product Information Label as shown in Figure 2-8.

Package Contents
In addition to the Spider distributed KVM -over-IP module, the package contains the following
items:
Null modem DB9F to RJ45 serial cable (30.48 mm;120 in)
AC Power Cables (1830 ± 30 mm;72 ± 1.2 in)
Mounting kit (see Chapter 4: Mounting Bracket Kit)
Quick Start Guide
Note: An optional external AC/DC power supply is available.
Installing the Spider
Consider the following factors when planning the installation of the Spider device.
USB Keyboard and Mouse Interfaces—Provides better remote cursor tracking. Some older
systems may not support USB devices or there may not be two USB ports available. In these
cases, the PS/2-interface model may be required. You configure either interface by using the
software.
Serial Ports—Performs the initial configuration to setup parameters and connects to a target
COM port. It also allows remote users to Telnet or SSH to that port, eliminating the need for a
separate box to perform serial command line management. The serial port can be used for
PPP connections to the user interface so that remote users can use a modem or other serial
interface. It can be the primary network connection or a backup connection in case the primary
LAN connection is unavailable.
Optional Auxiliary DC Power Supply (Redundancy)—Overcomes the loss of power when the
attached server goes down by using the auxiliary DC power supply connected to an
independent AC power source. The Spider device will always have power regardless of the
state of the server.
3: Installing the Spider Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 26
Ethernet Ports—Connects to the LAN. The Spider device contains a hardware Ethernet switch
that connects to the external ports and an internal CPU. The first port is required for network
connection. The second port can be used for the following:
- Tie all of the Spider units in a rack together so that one network connection only is
required. While this configuration is a “daisy” chain physically, logically each Spider device
has its own IP address on the network. Because the Spider device data that comes from
the end of the chain traverses all of the switches, latency increases and responsiveness
degrades depending on the number of devices in the chain.
Lantronix recommends a maximum of 16 Spider devices in a chain. But, if the network
switch that connects to the Spider device chain supports Spanning Tree, the first and last
devices in the chain can connect to the same network switch to provide resilience against
a single-point failure.
- Connect to the LAN management port on the server, so that an external management
network can interface to the Spider device and the server by using one cable.
- Connect to the main LAN port on the server. If physical isolation of management and user
data is not a concern, a single LAN cable can provide connectivity to the Spider device
and server conserving a switch or router port.
- Aggregate any other Ethernet connection as a general-purpose switch port.
Batch vs. Individual Setup—Deploying a batch of Spider devices at once should be performed
as a stage before attaching to the computers. The staging can be performed on a bench prior
to configuration. Consider the following tips for configuring a batch of Spider devices:
- Keyboard, video, and mouse connections are not required for setup. All you need are a
source of power and a serial connection to set up the network parameters, and an
Ethernet connection to access the administration user interface.
- Tag each Spider device with its IP address or write it on the serial number label on the
bottom.
Perform the following steps to install the Spider device and configure the initial network settings.
1. Plug the RJ45 cable into the Spider serial port which is shown in Figure 3-1. The RS-232
protocol is the standard for serial binary data signals.

Target Computer Setup
Setting up the target computer involves ensuring that the video resolution and refresh rates are
correct for the target computer monitor; that the mouse-to-cursor movement is sync’d properly;
that the Telnet/SSH connections match the Spider device; and, that the cable connections are
correct. Each of these items are discussed in more detail in the following:
Video Resolutions and Refresh Rates Configuration
Mouse-to-Cursor Synchronization
Telnet/SSH Connections to Serial Ports
Cable Connections for KVM and USB
3: Installing the Spider Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 31
Video Resolutions and Refresh Rates Configuration
The Spider device recognizes video resolutions on the target computer up to a maximum of 1600
x 1200 at 60 Hz if its hardware revision G22, G23, E21 or higher. If the Spider hardware is an
earlier revision, it will only support up to 1280 x 1024 resolution at 60 Hz. For the complete list of
supported video resolutions and refresh rates, see Chapter 3: Supported Resolutions and Refresh
Rates on page 127.
Note: The other supported resolutions and refresh rates are recognized by the Spider
device, but could be difficult if the timing does not comply with the extended display
identification data (EDID) standard that Spider device supports.
Perform the following steps to configure the video resolution and refresh rate.
Windows Server
1. Select Control Panel > Display > Settings. Modify the screen resolution value as required.
2. Select Control Panel > Display > Settings > Advanced > Monitor. Modify the screen
refresh rate. Because the server video card is driving the Spider device and not a monitor, a
refresh rate higher than 60 Hz has no effect.
Linux Server
1. Edit the Xfree86 file “XF86Config” to disable formats that are not supported or not VESA
standard timing.
2. Reboot is required.
Notes:
Background wallpaper and desktop appearances do not have any particular limitations.
Microsoft Active Desktop and Linux virtual desktop are not supported. If bandwidth is a
concern, plain backgrounds are preferred.
If you are using a special video card or OS, consult the documentation.
Mouse-to-Cursor Synchronization
Mouse-to-cursor synchronization can be an issue with digital KVM interfaces because PS/2 mice
transmit incremental information about movement over a period of time rather than an absolute
measurement.
The OS driver translates acceleration-to-distance based on the local screen resolution and applies
linear or nonlinear acceleration mappings. When a remote client communicates with the target
server, settings and screen resolutions on both sides of the connection must be taken into account
to get natural mouse-to-cursor tracking.
Use the USB keyboard and mouse when supported by the target computer. Unlike the PS/2
interface, a USB mouse uses absolute coordinates rather than relative coordinates and does not
present translation issues between the local and remote computers.
The PS/2 Spider model sets the keyboard and mouse interface to Auto. When it first attempts to
use the USB interface, and if it does not detect a USB interface, it falls back to PS/2.
There are no restrictions on the mouse settings of the client systems and no special care must be
taken when setting mouse parameters of target servers for USB mice. The PS/2 interface
performance (tracking) and synchronization can be optimized by removing any special
acceleration or nonlinear ballistics.
3: Installing the Spider Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 32
Perform the following steps to configure the mouse-to-cursor synchronization.
Windows Server
1. Select Control Panel > Mouse > Pointer Options.
2. Set the pointer speed to medium and disable Enhanced pointer precision.
Linux Server
1. Set Mouse Acceleration to exactly 1 and threshold to exactly 1.
2. Select Other Operating Systems on the Spider mouse settings page.
Solaris Server
1. Set the mouse settings by using the CDE control panel to “1:1, no acceleration” or “xset m 1”.
Mac OS X Server
1. Set the Spider device to Single Mouse Mode.
Telnet/SSH Connections to Serial Ports
To Telnet/SSH to a target computer serial port, you must Telnet/SSH to the Spider serial port first
and use connect serial CLI. This connects your Spider device to the target computer serial
port. The default settings are 9600 bps, 8 data bits, 1 stop bit, no parity, and no flow control. The
pinout of the included Spider cables match a standard DB9 COM port.
Cable Connections for KVM and USB
Connections for KVM and USB are integrated into the Spider device. Do not use extension cables.
Plug the Spider device directly into the ports on the host server. If using the Spider serial port, plug
the cable into the COM port on the server.
The second Cascade Ethernet port can connect to the Spider device to the target computer
management LAN port, or to a main LAN port, or to a Spider device chain. When connecting the
Ethernet ports, straight through or crossover cables can be used, because the Spider device has
auto-polarity and auto-crossover correction. Although the port marked Ethernet and the port
marked Cascade are both Ethernet interfaces, you must use the port marked Ethernet if using only
one Ethernet interface.
Perform the following steps when daisy chaining Spider devices.
1. Plug the outside network cable into the left Ethernet port of the first Spider device.
2. Connect the right Cascade port to the left port of the next Spider device in the chain.
3. Repeat as necessary. The last Spider device in the chain should have its right port
unoccupied, unless cabling in a loop for redundant connection.
Device Failure or Cable Break in the Daisy Chain
If a device fails or there is a cable break in the daisy chain, there could be a loss of network
connectivity for all devices downstream from the cable break or device failure. Avert this issue by
installing Spanning Tree in the switch or router to which the Spider device chain attaches. Then,
connect the last Spider device from its Cascade port to the same switch so that there is a
redundant outside connection.
3: Installing the Spider Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 33
Spanning Tree protocol implemented in the switch disables one of the two network connections
while the loop remains complete. Data flows in one direction only around the loop. If the loop
breaks, Spanning Tree activates both connections, so that data flows in both directions. All
devices in the Spider device chain are accessible except the one immediately downstream from
the cable break or failed device. Do not try this workaround without Spanning Tree installed.
Client Server Setup
Two mechanisms provide the monitoring of client servers that are connected through the Spider
device: platform-dependent management and platform-independent management.
Platform-dependent management—Spider View software is a standalone Windows XP or later
application that locates, manages, and accesses multiple Spider devices in an integrated
view. Spider View software requires ActiveX controls enabled. Refer to the Spider View User
Guide at http://www.lantronix.com/support/documentation.html for instructions on installation
and operation of Spider View software.
Platform-independent management—Each Spider device contains an embedded web server
that delivers web pages, a Java KVM Remote Console program, and a terminal program. To
access and manage the client server, a web browser is required. For example, use the latest
version of Internet Explorer, Netscape, FireFox, and Safari. To run the Remote Console
window and manage the target server, a Java plug-in (SUN JRE 1.4 or later) is required.
Network Environment
The connection between the client and Spider device must be open to IP traffic and use TCP ports
80 (HTTP) and 443 (HTTPS). Firewalls and NAT devices should be configured to support this
configuration. The TCP ports can be changed by accessing Interfaces > Network.
When idle, minimal network traffic gets generated. Traffic bursts exceeding 10 Mpbs can occur if
images change rapidly on the host server and image quality gets set to the maximum. Lantronix
recommends using Fast Ethernet connections and a switched network environment because In a
LAN, traffic affects the responsiveness of the Remote Console window.
Spider Power
The Spider device consumes under 4 watts of power that it draws from the attached computer. It
requires all cables to be plugged in to receive sufficient power.
Plug in both USB cables or a USB and a PS/2 cable. Pwr1 and Pwr2 LEDs indicate that power is
available. Pwr1 indicates that power is available only on the first USB port. Pwr2 indicates that
power is available on the second USB port or the PS/2 port. When both LEDs are lit, the Spider
device is powered and can boot.
The Spider device can also get power from an external DC power supply. DC power supplies are
available from Lantronix (part number 520-085-R). The DC power supply acts as a backup,
because the Spider device loses power when the attached computer goes down.
Use the power-on reset to reboot the Spider device or reboot from the user interface, from the
serial port, or by clicking the reset switch through the pinhole on the back of the body.

The SpiderDuo devices recognize video resolutions on the target computer up to a maximum of
1600 x 1200 at 60 Hz. For the complete list of supported video resolutions and refresh rates, see
Chapter 3: Supported Resolutions and Refresh Rates on page 127.
Note: The other supported resolutions and refresh rates are recognized by the
SpiderDuo devices, but could be difficult if the timing does not comply with the extended
display identification data (EDID) standard that SpiderDuo supports.
Perform the following steps to configure the video resolution and refresh rate.
Windows Server
1. Select Control Panel > Display > Settings. Modify the screen resolution value as required.
2. Select Control Panel > Display > Settings > Advanced > Monitor. Modify the screen
refresh rate. Because the server video card is driving the SpiderDuo device and not a monitor,
a refresh rate higher than 60 Hz has no effect.
Linux Server
1. Edit the Xfree86 file “XF86Config” to disable formats that are not supported or not VESA
standard timing.
2. Reboot is required.
Notes:
Background wallpaper and desktop appearances do not have any particular limitations.
Microsoft Active Desktop and Linux virtual desktop are not supported. If bandwidth is a
concern, plain backgrounds are preferred.
Mouse-to-Cursor Synchronization
Mouse-to-cursor synchronization can be an issue with digital KVM interfaces because PS/2 mice
transmit incremental information about movement over a period of time rather than an absolute
measurement.
The OS driver translates acceleration-to-distance based on the local screen resolution and applies
linear or nonlinear acceleration mappings. When a remote client communicates with the target
server, settings and screen resolutions on both sides of the connection must be taken into account
to get natural mouse-to-cursor tracking.
Use the USB keyboard and mouse when supported by the target computer. Unlike the PS/2
interface, a USB mouse uses absolute coordinates rather than relative coordinates and does not
present translation issues between the local and remote computers.
The PS/2 model sets the keyboard and mouse interface to Auto. When it first attempts to use the
USB interface, and if it does not detect a USB interface, it falls back to PS/2.
There are no restrictions on the mouse settings of the client systems and no special care must be
taken when setting mouse parameters of target servers for USB mice. The PS/2 interface
performance (tracking) and synchronization can be optimized by removing any special
acceleration or nonlinear ballistics.
Perform the following steps to configure the mouse-to-cursor synchronization.
Windows Server
1. Select Control Panel > Mouse > Pointer Options.
4: Installing the SpiderDuo Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 41
2. Set the pointer speed to medium and disable Enhanced pointer precision.
Linux Server
1. Set Mouse Acceleration to exactly 1 and threshold to exactly 1.
Solaris Server
1. Set the mouse settings by using the CDE control panel to “1:1, no acceleration” or “xset m 1”.
Telnet/SSH Connections to Serial Ports
To Telnet/SSH to a target computer serial port, you must Telnet/SSH to the SpiderDuo serial port
first and use connect serial CLI. This connects your SpiderDuo device to the target computer
serial port. The default settings are 9600 bps, 8 data bits, 1 stop bit, no parity, and no flow control.
The pinout of the included SpiderDuo cables match a standard DB9 COM port.
Cable Connections for KVM and USB
Connections for video, USB, and keyboard/mouse are integrated into the SpiderDuo device. Plug
the SpiderDuo device directly into the appropriate ports on the host system. If using the serial port,
cable it to the appropriate COM port on the server. Available extended-length cables are shown in
Table 4-9.
Power Sequencing
To ensure that the system (PC, local keyboard and mouse, and SpiderDuo device) function
properly at power up, it is recommended that the following procedure be performed.
1. Ensure that the PC and SpiderDuo are powered off.
2. Make connections for all devices.
3. Turn on the SpiderDuo first and wait for the SpiderDuo to boot up completely. The SysOK LED
will be on steady.
4. Turn on the PC.
Client Server Setup
Two mechanisms provide the monitoring of client servers that are connected through the Spider
device: platform-dependent management and platform-independent management.
Platform-dependent management—Spider View software is a standalone Windows XP or later
application that locates, manages, and accesses multiple Spider devices in an integrated
view. Spider View application requires ActiveX controls enabled. Refer to the Spider View
User Guide at http://www.lantronix.com/support/documentation.html for instructions on
installation and operation of Spider View software.
Table 4-9 Extended Length Cables
Item Part Number
USB connecter; 1500 mm, (59 in.) VGA cable 500-199-R
PS/2 and USB connectors; 1500 mm, (59 in.) VGA cable 500-200-R
4: Installing the SpiderDuo Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 42
Platform-independent management—Each Spider device contains an embedded web server
that delivers web pages, a Java KVM Remote Console program, and a terminal program. To
access and manage the client server, the latest web browser is required. For example,
Internet Explorer, Netscape, FireFox, and Safari. To run the Remote Console window and
manage the target server, a Java plug-in (SUN JRE 1.4 or later) is required.
Network Environment
The connection between the client and SpiderDuo device must be open to IP traffic and use TCP
ports 80 (HTTP) and 443 (HTTPS). Firewalls and NAT devices should be configured to support
this configuration. The TCP ports can be changed by accessing Interfaces > Network.
When idle, minimal network traffic gets generated. Traffic bursts exceeding 10 Mpbs can occur if
images change rapidly on the host server and image quality gets set to the maximum. Lantronix
recommends using Fast Ethernet connections and a switched network environment because In a
LAN, traffic affects the responsiveness of the Remote Console window.

Spider™ and SpiderDuo® KVM-over-IP Device User Guide 43
PCU Power
To remotely control power to a PC and other equipment, an optional PCU is available (part
number PCU100-01). The PCU manages power remotely to a target PC and other equipment. In
addition, the user can restart or power-cycle the PC and other equipment. shows the layout and
dimensions of the PCU.
Figure 4-10 PCU Layout and Dimensions
Complete the following tasks to connect the PCU.
1. Connect the power output plug to a target PC or other equipment.
2. Connect the RJ45 cable from the PCU to the SpiderDuo serial port.
3. Connect the power input plug to AC power. Green LED = PCU ON (AC power pass- through),
Blue LED = Sys OK.
4: Installing the SpiderDuo Device
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 44
Warning: AC power passes through by default if the RJ45 cable is disconnected
from the PCU.
The SpiderDuo device gets its power from an external DC supply. Replacement power supplies
are available.

6: Remote System Control
This chapter describes the components of remote system control. It contains the following
sections:
Overview
Remote Console Window
Basic Remote Console Operation
Optimizing Video
Keyboard Functions
Other Remote Console Functions
Telnet/SSH
Overview
The Lantronix Spider and SpiderDuo devices control the target system by using a Remote
Console. The Remote Console has settings that apply each time a user launches it. Other settings
can be applied within the window itself. By scaling the window down in size, it is possible to have
multiple Remote Console windows open, allowing interaction with multiple target systems.
Remote Console Window
The Remote Console window shows a real-time replica of the target system video (mimicking a
monitor plugged directly into the remote computer). When the local computer window displays in
the Remote Console window, mouse movements and keystrokes are transmitted to a remote
computer. The title bar of the window shows the IP address of the Spider device or SpiderDuo
(useful when multiple windows are open on the client system).
The Remote Console window can be minimized, maximized, or scaled in either direction. There
are Main viewport and scroll bars, button keys, and a toolbar which are described in the following
subsections.
To launch the Remote Console window, perform the following steps.
1. Click KVM Console to launch the Remote Console window. The Remote Console window can
open in the foreground or in the background. If it launches in the background, click on the icon
to bring the window to the front.
2. Or, launch the Remote Console by clicking the link below the preview image on the KVM
Console Preview window.
You can enable the Spider or SpiderDuo device to bypass the web page and take you directly
to the remote system by clicking Services > Security > Authentication Limitation > Enable
Direct KVM. This capability is called Direct KVM.
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 47
Figure 6-1 Remote Console Window Components
Main Viewport and Scroll Bars
When first launched, the full virtual screen of the target computer is mapped pixel-for-pixel to the
console window main viewport. As a result, if the target is running at a resolution less than that of
the client, the entire screen is visible in the Remote Console window. If the resolution is such that
the screen does not fit, scroll bars are available in the Remote Console window to move the
viewport around within the target’s screen. The virtual screen size of the target may also be scaled
down to match the Remote Console window.
Button Keys
Along the top there are Button Keys that have been defined to send special key codes directly to
the target computer.
Toolbar
The top toolbar has a number of buttons for one-click access to functions, and a drop-down menu
where other options may be reached. The icons vary depending on which keyboard interface is
active.
Access Virtual Media—The left-most diskette icon is used to activate the Virtual Media
toolbar.
Auto Adjust Video—This button activates the Auto Adjust Video function. When first opening
the Remote Console window, it is recommended to click this button to ensure the Spider
device has locked on to the video format on the attached computer. Also, click this button if
there is an offset from the proper horizontal or vertical start position relative to the target
screen (black bars to the right, left, top, or bottom of the main viewport, or a distorted video).
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 48
Screen Display Adjustments—These 3 buttons (A,S,R) facilitate changes to the Screen
display
Sync Mouse, Single/Double Cursor—These icons appear when the PS/2 mouse interface is
active.
Options
The drop-down menu provides access to a number of options and features.
Information Bar - Connection
The left side of the information bar indicates whether the connection is encrypted (Console (SSL))
or unencrypted (Console (Norm)).
Information Bar - Resolution
Displays the horizontal by vertical resolution of the target system’s video.
Information Bar - Network Traffic
Displays the approximate number of bytes per second incoming and outgoing to the window. An
indication of the number of frames per second (fps) updated is also displayed. Incoming data is
generally comprised of video updates. Outgoing data is generally comprised of keystrokes and
mouse movements. When the target screen is not changing, In should be low or zero. If not, click
the auto-adjust button. The amount of network traffic is a function of the detail in the captured
screen, the rate at which the screen is changing, and the video encoding settings.
Concurrent Access State
One user is connected to the Remote Console
Multiple users are connected to the Remote Console
This user has exclusive access to the Remote Console. No other clients may access the
target system until exclusive access is disabled.
Another user has exclusive access to the Remote Console. No other clients may access the
target system until exclusive access is disabled by that user, or until that user closes their Remote
Console window.
Monitor Only State
The far right icon shows whether this client may interact or simply view the target computer. If
Monitor Only is disabled, then the keyboard and mouse may interact with the target. If Monitor
Only is enabled, the client is view-only.
Exclusive Access
Only one user at a time may access the Spider device or SpiderDuo.
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 49
Basic Remote Console Operation
When the Remote Console window is open, there are three key zones:
Outside the Remote Console window, interaction is with the local computer’s operating system
or applications.
Inside the Remote Console window’s viewport, interaction is with the target computer.
Inside the Remote Console window but outside the viewport, interaction is with the Remote
Console control functions such as the toolbar or scroll bars.
Figure 6-2 Remote Console Window
Within the Remote Console viewport, interaction with the remote computer is generally the same
as if there were a direct connection (with a minor lag due to network latency). Windows may be
opened, applications run, settings changed, maintenance functions performed, even system
reboots performed. Powering down the target computer results in powering down the Spider
device or SpiderDuo unless the redundant supply is used.
Figure 6-3 Remote Console Toolbar
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 50
Auto Video Adjustment
The left side of the target computer screen must be aligned with the left side of the Remote
Console viewport so that the tops align as well. If not, the local and remote cursors will always
have a fixed offset of that amount, even if the USB interface is used. Clicking the Auto Video
Adjustment one or more times typically cures any offset.
Screen Display Adjustments
Three features are added to the toolbar to facilitate Screen display changes:
A—Full Screen Mode (Ctrl+F10).
S—Full Screen Stretch Mode (Ctrl+F10 to return to regular mode).
R—Full Screen Mode with Changing Client Monitor Resolution (Ctrl+F10 to return to regular
mode).
Fast Sync and Intelligent Sync
The Spider device uses two different algorithms for re-synchronizing local and remote cursors.
Use the Fast Sync button on the toolbar to correct a fixed skew.
Intelligent Sync uses a different algorithm and is useful when the mouse settings have changed on
the remote system or when Fast Sync does not work. It is accessed through the Options > Mouse
Handling drop-down menu. The Sync button on the toolbar usually performs a Fast Sync, but will
perform an Intelligent Sync if the video format has recently changed.
Single and Double Mouse Modes
Continuous synchronization of local and remote cursors may not be feasible. The Spider device
provides a mode where only one cursor is visible when operating in the active Remote Console
viewport. Click the Single/Double button on the toolbar to activate Single Mouse Mode. This is
indicated by a single arrow in the Single/Double button. When in this mode, the Java KVM
console “grabs” the local cursor after clicking within the viewport and will not release it until a
“release-cursor” hot key sequence is given (Alt+F12 by default). As there is only one cursor, and
that one is confined to the active viewport, there is no issue with local to remote cursor tracking.
There also is no local cursor; Alt+F12 is required to free the cursor to move the focus from the
active viewport. Clicking when the local cursor is within the viewport will re-grab the cursor. Single
Mouse Mode may be exited by clicking on the Single/Double button.
If at some point the cursor seems to disappear, click Alt+F12 or check the Single/Double Button
as Single Mouse Mode may have been entered in error.
Note: Single Mouse Mode requires Sun Java 1.4 or higher
Local Cursor
The Spider device has an option to change the appearance of the local cursor when the focus is
on the remote computer. Select Options > Local Cursor and select one of the following cursor
options:
Default—the local cursor maintains its appearance regardless of the focus location
Transparent—the local cursor is invisible when the focus is on the remote computer. This is
similar to Single Mouse Mode except the cursor is not “grabbed” and will reappear when
moved outside of the active viewport.
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 51
The other selections provide a change of appearance for a visual clue that the focus is on the
remote computer; the cursor changes back when the focus is back at the client system
(including those areas of the Remote Console window outside the main viewport.)
Selections made in the Local Cursor submenu are associated with the current user and will be
saved for the next Remote Console session.
Optimizing Video
The Spider and SpiderDuo devices can automatically make adjustments to video settings
including clock and phase, and encoding to ensure that a picture displays quickly. You can also
manually specify the settings.
Auto and Manual Video Adjustment
The Spider device automatically recognizes and adapts to many standard video resolutions and
refresh rates. When it first enters the Remote Console window, it recognizes and locks onto the
video in order to provide a picture as soon as possible.
Once the window displays, click the Auto Video Adjustment button once or twice to provide a
greater degree of optimization. The Auto Adjustment process analyzes the timing of the incoming
video horizontal and vertical sync signals then adjusts the digitizing hardware parameters. If there
is slightly nonstandard timing, these parameters may be manually fine-tuned.
If it is necessary to adjust video hardware parameters, this may be done from Options > Video
Settings. This brings up a window with a number of slider bars.
Adjust the brightness and contrast of the Remote Client window as presented by the Auto
Adjustment. This is a hardware parameter and applies to all Spider users. Overall brightness and
the contrast levels of each of the red, green, and blue primaries may be modified up or down. The
Remote Console window immediately reflects the change. Once there is a satisfactory color-
mapping, click Save Changes to retain those colors permanently for that video format. To discard
the changes made, click Undo Changes. To return a particular setting or all settings to the original
factory defaults, click Reset this Mode or Reset All Modes.
See Appendix C: Supported Resolutions and Refresh Rates for more information.
Clock and Phase
The A/D converter uses these low-level settings in the digitization process. Adjustment should not
be required unless advised by Lantronix Tech Support.
If the timing of the video signal is slightly off, the Auto Adjustment may not capture the frame at the
right point. This will result in black bars along left, right, top, or bottom of the Remote Console
viewport, and cutting off the opposite side of the captured image. The Offset sliders can be used to
align the sides properly. Once there is correct alignment, click Save Changes to retain those
settings permanently. To discard the changes made, click Undo Changes. To return a particular
setting or all settings to the original factory defaults, click Reset this Mode or Reset All.
Video Encoding
Various video encoding schemes have been defined to try to tailor the bandwidth usage to what is
available. In addition to the predefined schemes, compression levels, and color depth can be
manually adjusted. The default settings for each user are established in the KVM Console
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 52
Settings > KVM_User > Transmission Encoding web page.
To change the settings during a session, select Options > Encoding > Predefined, Encoding >
Compression, Encoding > Color Depth, and Encoding > Lossy manual adjustments. These
settings will be lost when the Remote Console window is closed; for nonvolatile changes use the
KVM Settings > User Console > Transmission Encoding web page.
Scaling Target Video to Client Resolution
In addition to the 1:1 pixel mapping mode, which is the default when the Remote Console window
is first launched, scaling factors may be applied to the captured video in order to match various
sizes of windows on the client. This scaling may be a fixed ratio or dynamically adjustable, as
selected from the Options > Scaling selection. The default is 100 percent, although it may result
in a viewport smaller than the virtual screen and is moved around with scroll bars. The optimal
viewing percentages are 25 and 50.
Keyboard Functions
The Spider and Spider Duo devices provide a number of useful functions for mapping or
translating between the local keyboard/keycodes and the emulated keyboard presented to the
target computer.
Soft Keyboard
With remote control of a computer, it may be that the target system and client system are in
different countries, using different languages. By using a Soft Keyboard, the local user can have
the keycodes available to send to the target that are not on the local keyboard, without worrying
about OS and application character set mappings.
Select Options > Soft Keyboard > Mapping to get a submenu listing the languages supported.
Make the desired selection, and then verify it with Show soft keyboard.
Select Options > Soft Keyboard > Show. This provides an image of the currently selected Soft
Keyboard. The Soft Keyboard sends single keystrokes as well as combinations of keys such as
Ctrl+C. For a single keystroke, click on the button with the desired character. Single keys such as
alphanumeric characters and punctuation are sent immediately. Special keys such as Ctrl, Shift,
and F1 to F12 must be selected twice. The first click sends the signal “key is clicked.” The second
click indicates the signal “key is released” to the remote system. After the first click the button will
change its color to indicate that the key remains clicked, and that a code has not been sent. After
the second click the button will appear as usual, showing that the keycode was sent.
Click the Close button on the title bar to close the soft keyboard.
Local Keyboard
The Java Virtual Machine running the Remote Console applet on the client computer determines
its keyboard language mapping automatically from the operating environment. There may be
circumstances where it is unable to do so, such as when the keyboard mapping and OS language
do not match. The Options > Local Keyboard selection allows manual designation of the
language/layout of the keyboard on the client system.
Hotkeys
Hotkeys provide an alternative method for sending keycode sequences defined in the section on
Remote Console Button Keys. Click Options > Hotkeys and select the Button Key to be sent. If
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 53
that Button Key has been defined with “Confirm”, a confirmation dialog box pops up before the
keycode is sent.
Other Remote Console Functions
Other remote console functions are described in this section. For example, monitor only
specifications, exclusive access, capture of the screen to the clipboard and refreshing the video.
Monitor Only
When Options > Monitor Only is checked, the keyboard and mouse are disabled for this Remote
Console window. The Monitor Only state is shown in the lower right corner of the Remote Console
status bar. The user must have the appropriate permissions to change this setting.
Exclusive Access
When Options > Exclusive Access is checked, no other client may open a Remote Console
window to this Spider device. Any open Remote Console windows on other clients will be
disconnected. The Exclusive Access state is shown in the lower right corner of the Remote
Console status bar. The user must have the appropriate permissions to change this setting.
Screenshot to Clipboard
Options > Screenshot captures a snapshot of the entire target system’s virtual screen to the
clipboard for pasting into other applications.
Refresh Video
The entire Remote Console viewport area is redrawn when the Remote Console window is first
opened, and when the Auto Adjust Video button is clicked. As the encoding settings and noise
filter may sometimes result in visible compression artifacts, selecting Options > Refresh Video
can be used to redraw the entire viewport area.
Telnet/SSH
In addition to interacting with the target system using the KVM Console, the Spider device also
allows text communication with the target via the Telnet Console, also a Java program window.
Telnet and SSH are network protocols that enable a tunnel from the client system to the Spider
device serial port. Once set up, it may be accessed through the web interface at the Telnet
Console window, or using a Telnet/SSH client to connect directly. Note that Telnet/SSH cannot be
used to connect to the Spider device itself in order to control it, as the device has an HTTP and not
a command line interface.
The Telnet Console is a Java program and has the same Java Runtime Environment requirements
as the Remote Console. When the Telnet Console window is open, the user at the client system
can send and receive characters directly to the serial port.
Set up and Enable
To use Telnet or SSH, the serial port must be put in passthrough mode with the appropriate
connection parameters and cabling with Telnet and/or SSH access allowed. If desired, the TCP
6: Remote System Control
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 54
port numbers also may be changed from their defaults. A user attempting to connect via Telnet or
SSH must also have the appropriate permissions.
Passthrough Use
When using Telnet/SSH in passthrough mode, the Spider device just acts as a conduit for the
serial data traveling between the client system and whatever is connected to the serial port. This
may be a COM port on the remote computer, or a serially controlled power strip, or anything else
with an RS-232 port.
1. From the client system, use a Telnet or SSH utility to connect to the IP address of the Spider
device, at the assigned Telnet TCP port number.
2. The Spider device will present LOGIN and PASSWORD prompts. Enter a valid user name
and password. The user must have permissions set to use Telnet or SSH.
3. The Spider device will reply with a Welcome and status, followed by a command line prompt.
Selections are:
Help—Displays a list of commands
Version—Displays the current Spider firmware version number
Connect Serial—Enter passthrough to serial port mode
Logout—Terminates the Telnet or SSH connection
4. Enter connect serial to open the connection to the serial port.
5. You are now connected and may interact with the attached serial console. Keystrokes are not
locally echoed and must be echoed by the connected serial device.
6. Use the SSH or Telnet ability to send and receive serial data between the client and the serial
port. The Spider device does not echo this data back to the client.
7. When complete, enter Esc-Exit to return to the command line.
8. Enter logout or l to close the connection.
Telnet Console Use
When using the Telnet Console, the Spider device opens a window on the client system that
provides direct access to the Telnet/SSH command line. This eliminates the need to have a Telnet
or SSH utility running on the client system.
1. Click the Terminal button at the top of the Spider page. The user must have permissions set
to use Telnet or SSH. The JRE will launch, and the Telnet Console window appears. Telnet
Console and Remote KVM Console windows may be open concurrently.

KVM Console Settings
The Remote Console window into the target system has settings that may be changed for the way
each individual user interacts with the Spider device. When a user is created by copying from an
existing user, the Remote Console settings will be copied as well. You can change these settings
on the Interfaces > KVM Console Settings page. Note that if you are using the Spider View
application, these settings do not apply; see the Spider View User Guide for further information.
Modem (Spider device
Only)
Connect to the Spider device with a dial-up or ISDN connection, using PPP.
Essentially, the Spider device acts as an ISP that you dial in to. The client
system will need to be set up accordingly, for example using the Windows
Network Connection Wizard. Change the following parameters as
necessary:
Serial Line Speed: Most modems support 115200 bps.
Modem Init String: The initialization string sent out to set up the modem.
If you have a special modem or are going through a PBX requiring an
access sequence, you may modify the string. Consult the modem’s
manual on the AT command syntax.
Modem server IP addresses: As part of the PPP handshake, IP
addresses are assigned to the remote device.
Modem client IP address: IP address assigned to the Spider device.
Passthrough Access to
serial port 1 via Telnet/
SSH
The serial port may be used to connect to the target server’s COM port for
integrated access to command line functions or used to control a serial-
interfaced peripheral. Telnet and SSH are network protocols that enable a
tunnel from the client system over the network to the Spider device’s serial
port. Once the port is set up, it may be accessed through the web interface at
the Telnet Console window, or using a Telnet/SSH client to connect directly.
Set the following parameters to match connected equipment:
Speed: The speed with which the device port exchanges data with the
attached serial device. From the drop-down list, select the baud rate. Most
devices use 9600 for the administration port, so the device port defaults to
this value. Check the equipment settings and documentation for the
proper baud rate.
Data bits: Number of data bits used to transmit a character. From the
drop-down list, select the number of data bits. The default is 8 data bits.
Parity: Parity checking is a rudimentary method of detecting simple,
single-bit errors. From the drop-down list, select the parity. The default is
none.
Stop Bits: The number of stop bit(s) used to indicate that a byte of data
has been transmitted. From the drop-down list, select the number of stop
bits. The default is 1.
Flow Control: A method of preventing buffer overflow and loss of data.
The available methods include none, software (xon/xoff), and hardware
(RTS/CTS). The default is none.

Spider™ and SpiderDuo® KVM-over-IP Device User Guide 62
The way in which the Spider device transmits video data back to the client system can be tailored
for the type of network connection. On a LAN where bandwidth is not an issue, compression is not
required and the speed of updates can be maximized. For other connections, the optimum user
interaction needs to trade off image quality and update speed to fit the size of the pipe. Because
various users may be accessing the Spider device over different connections, these parameters
are applied on a user-by-user basis. The default is set for maximum image quality and speed of
updates, which results in high data rate and hence is suitable for LANs where bursts of up to 2
Mbytes/second are acceptable.
To modify the user console, perform the following steps.
1. Click Interfaces > KVM Console. The Remote Console Settings for User page displays.

Automatic Detection This option uses an algorithm to try to determine what sort of connection is
being used, and sets up parameters to match. These settings may change
from login to login depending on the state of the network at that point.
Preconfigured Establishes a set of parameters optimized for each of a number of
connection types. The default transmission encoding is LAN (high color),
which is uncompressed with a 16 bit color depth. Other data networks may
be chosen from the Network speed drop-down list, and the compression
and color depth will be configured accordingly.
Manual Allows the direct control of the compression factor and color depth. The
simplest way to reduce bandwidth is to cut the color depth down to 8 bits;
subtle color shades will be gone but the overall image is very usable. Dialing
up the compression level also makes available even further reductions in
color depth, all the way down to black and white (1 bit.) As compression level
increases and/or color depth decreases, image quality and responsiveness
to changes deteriorates but required bandwidth is reduced.

Video
The Spider device works by capturing and digitizing the analog video coming from the attached
computer. This analog video may have more or less low-level electrical noise present, depending
on the nature of the video card or embedded video controller.
When viewed on a monitor, this noise (if random) is invisible as the display is being redrawn 60 to
100 times a second. Inside the Spider device, however, the algorithm sees that noise as
something changing on the screen, so that requires sending off an update to the client system.
This can result in a constant stream of data even when the image on the target computer’s screen
is not moving. In order to avoid this, at Interface > Video > Miscellaneous Video Settings the
Spider device has a selection for noise filter. The larger filter openings will filter out more of the
noise, at the cost of potentially missing small incremental changes and seeing some compression
artifacts (blocky-ness). Filter settings of Medium or High will work for most applications. Be sure
to try the Remote Console Auto Adjust Video button a few times before deciding that a constant
stream of data represents electrical noise requiring a larger filter setting.
To modify video settings, perform the followings steps.
1. Click Interfaces > Video. The Miscellaneous Video Settings page displays.

Virtual Media
The Spider device provides a powerful capability called Virtual Media (or Virtual Disk). Using the
USB port, the Spider device can present either a local floppy disk image or a redirected remote
CD-ROM image to the target computer. This can allow system recovery in conditions as bad as
having local disks down and no primary network connection.
With Floppy Disk Image, the user can upload an image to the Spider device’s memory, which then
emulates a locally attached floppy drive. With CD-ROM Image, a Windows or other SAMBA share
can emulate a locally attached CD-ROM, for instance to update software.
Drive Redirection allows you to share (redirect) your local drive (floppy drives, hard disks, CD
ROMs and other removable devices like USB sticks) with the remote system over a TCP network
connection.
Thus, with Drive Redirection, you can use a virtual disk drive on the remote computer instead of an
image file. It is also possible to enable a remote machine to write data to your local disc.
Note: Drive Redirection supports only Windows as the client computer since it redirects
based on a drive letter.

Local vs. Remote Authentication
User names and groups may be administered on the Spider device to allow varying levels of
access and control to different classes of users. To log in to the Spider device, a user must be
authenticated by means of a password. This authentication may take place locally, where the user
name and associated password are stored in the Spider device’s memory. The Spider device may
query a centralized database using RADIUS or LDAP to determine if a given user may log in. In
both of these cases, the user name must be defined on the Spider device where it has its
permissions assigned.

are ignored when the box is not checked.
Default Action If after evaluation of all rules a request for connection from a given IP
address has not had either an Accept or Drop decision made, this selection
can allow it to be either Accepted or Dropped. In other words, this drop-down
defines the default action for IP addresses with no rules defined.
Rule creation and
editing
Spider devices come from the factory with one rule defined as an example of
the rule structure: Rule 1 allows all groups access from source IP 0.0.0.0 to
255.255.255.255. Additional rules may be entered in the edit boxes.
Rule Number: Defines where in the evaluation sequence this rule is to
be applied.
Starting and Ending IP Addresses: Define the range over which the rule
applies.
Group: Defines which user group is affected by this rule. Built-in groups
include Admin, All, and Unknown (no group assigned). As additional
groups are defined in User ManagementUsers
Group Management, they will appear in the drop-down. A rule can apply
to only one group at a time.
Action: Chooses whether this is to be a Drop or Accept rule.
After a rule has been defined, it needs to go in the correct place in the list.
Append: Puts the rule at the end of the list. The rule number changes to
reflect the last position on the list.
Insert: Puts the rule in the place on the list indicated by the rule number,
renumbering and moving down the other rules to make room.
Replace: Deletes the previous rule of that number and replaces it with the
new rule.

9: Services
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 87
Certificate
The Spider device uses the Secure Socket Layer (SSL) protocol for any encrypted network traffic
between itself and a connected client. During the connection establishment the Spider device has
to expose its identity to a client using a cryptographic certificate. Upon leaving the factory this
certificate and the underlying secret key is the same for all Spider devices and will not match the
network configuration where it is installed. The certificate’s underlying secret key is also used for
securing the SSL handshake. Leaving the default certificate unmodified is all right in most
circumstances and is necessary only if the network facility is vulnerable to man-in-the-middle
attack.
It is possible to generate and install a new base64 x.509 certificate that is unique for a particular
Spider device. The Spider device is able to generate a new cryptographic key and the associated
Certificate Signing Request (CSR) that needs to be certified by a certification authority (CA).
To create and install an SSL certificate, perform the following steps.
1. Click Services > Certificate. The Certificate Signing Request page displays.
Figure 9-4 Certificate Signing Request Page
2. Modify the following fields.
Field Description
Common name The network name of the Spider device once it is installed in the user’s
network (usually the fully qualified domain name). It is identical to the name
that is used to access the Spider device with a web browser without the
prefix http://. In case the name given here and the actual network name
differ, the browser will pop up a security warning when the Spider device is
accessed using HTTPS.
Organizational unit This field specifies to the department within an organization to which the
Spider device belongs.
Organization The name of the organization to which the Spider device belongs.
Locality/City The city where the organization is located.

logging in to the Spider device.
Technically, the number of Spider devices that can be viewed and accessed on one web page is
unlimited. It is important to note that the more Spider devices that are added, the slower the
response time will be.
Anyone with a Google email account (gmail.com) can create an iGoogle gadget for viewing web
pages. There are two types of iGoogle gadgets: public gadgets and private gadgets. When you
submit a gadget’s XML code to Google, it becomes part of the iGoogle public gadgets, which are
listed for import on iGoogle web pages. When a gadget’s XML code is stored on a private server,
the gadget stays private and is usable only by users who are aware of its location.
To use iGoogle gadget to manage multiple Spider devices, perform the following steps.

Appendix A: Troubleshooting
No connection can be established to the Spider device.
Check cabling. Are both USB cables or all of the USB and PS/2 cables plugged in? Are both Pwr
LEDs lit? Is the Ethernet cable plugged in, and the Link light lit? Is there Activity?
Have a look on your network. Verify your network configuration (IP address, router). Send a ping
request to the Spider device to find out whether the Spider device is reachable via the network.
Establish a direct connection between the Spider device and the client. If you use a firewall then
check the appropriate port for accepting connections. The TCP ports 80 (for HTTP) and 443 (for
both HTTPS and RFB) have to be open (the server providing the firewall has to accept incoming
TCP connections on these ports). You may restrict these connections to the IP addresses used by
the Spider device and your client.
Login on the Spider device fails.
Verify both your user login and your password. By default, the user sysadmin has the password
PASS. Ensure the web browser is configured to accept cookies.
The Remote Console window of the Spider device does not open.
A firewall may prevent access to the Remote Console (TCP port 443). If there is a proxy server
between the Spider device and your host, then you may not be able to transfer the video data
using RFB. Check the settings of the Spider device and choose a different server port used for
RFB transfer. A Java Runtime Environment may not be installed, or may be disabled.
The video quality is bad or the picture is grainy.
Enter the Remote Console and click the Auto Adjust button to adjust the Spider device’s video
input parameters to the correct values.
Special key combinations (e.g., ALT+F2, ALT+F3) are intercepted by the client system and
not transmitted to the remote computer.
You have to define a Button Key. This can be done in the Remote Console settings. Alternatively,
use the soft keyboard feature.
The Spider device web pages are not displayed correctly.
Check your browser’s cache settings. Ensure the cache settings are not set to “do not check for
newer pages." Otherwise the web pages may be loaded from your browser cache and not from the
Spider device.
Every time I open a dialog box with some buttons, the mouse pointers are not synchronous
anymore.
Disable the setting Automatically move mouse pointer to the default button of dialog boxes
in the mouse settings of your operating system.
The Remote Console does not open with Opera in Linux.
Some versions of Opera do not grant enough permission if the signature of the applet cannot be
verified. To solve the problem, add the lines grantcodeBase "nn.pp.rc.RemoteConsoleApplet"
{permission java.lang.RuntimePermission "accessClassInPackage.sun.*"; to the java policy
file of opera (e.g., /usr/share/opera/java/opera.policy).
Appendix A: Troubleshooting
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 121
I forgot my password. How can I reset the Spider device to factory defaults?
Use the serial interface with a terminal emulator program set to 9600 or 115200, 8 bit characters,
No parity, 1 Stop bit, and No flow control. Within 2 seconds of booting the Spider device, press the
Esc key a few times to get a =>prompt. Type defaults at the => prompt.
If you can't get the => prompt after several tries at 9600, try 115200. Earlier firmware sets the
serial console port to 115200 by default.
Cannot upload the signed SSL certificate in MacOS X.
If an “internal error” occurs while uploading the signed certificate either changes the extension of
the file to .txt or adds a file helper using the Internet Explorer preferences for this type of file. Make
sure that the encoding is set to “plain text” and the checkbox “use for outgoing” is set. As an
alternative, you may also use a Mozilla based browser (Mozilla, FireFox).
If you cannot get into the BIOS of your system or you cannot boot your system using
Virtual Media, try some of the following:
If you have a PS/2 model Spider device:
1. Under Interfaces:Keyboard/Mouse – Check the Force USB Full Speed Mode box.
2. Under Interfaces:Keyboard/Mouse – Set the Host Interface to PS/2
3. If your system only has USB and no PS/2, do the above and use a PS/2 to USB adapter
If you have a USB model Spider device, in Interfaces:Keyboard/Mouse, check the Force USB
Full Speed Mode box.
If the key used to enter BIOS setup or the boot menu on your PC is intercepted by your client OS,
add a Virtual Key under Interfaces:KVM Console Settings.

Appendix B: Virtual Media Example
Goal
In this example, the goal is to put a rescue CD (a CD used to boot a PC when the hard-disk
corruption prevents OS boot) on PC#3 so that the rescue CD can be used by any Spider devices
on the network.
Figure B-1 Virtual Media
In this example, PC#2 cannot boot from its hard disk, so the user wants to use the rescue CD to
boot the PC. We assume PC#2 can boot from external USB device.
Step 1 – Prepare the VM Server
1. Use any CD-copy application to create an ISO image of the rescue CD, and call this ISO
image file boot.iso.
2. On PC#3 (Windows XP in this example), put the ISO file in a Windows folder – file boot.iso
in folder aaa as shown in the diagram below.
Appendix B: Virtual Media Example
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 123
Figure B-2 Windows Browser
3. Right-click the folder aaa and select the “sharing” menu. The default name is the folder name
but changed to share_some_folder as shown in the diagram below.
Figure B-3 Firewall Properties Window
Now, the file boot.iso can be used from a Spider device. The file can be left there permanently,
and when a PC/server crashes and cannot boot, the combination of this file and the Spider device
will be used to boot the PC/server.
Step 2 – Enable Virtual Media
In this example, PC#2 does not respond, and rebooting does not cure the problem. PC#2 has
Spider device#2 attached.
1. On any PC (call this the client PC), bring up a browser, browse to Spider device#2, and log in.
Appendix B: Virtual Media Example
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 124
2. Go to the Virtual Media page and complete the fields in the Image on Windows Share section
of the page as shown in the diagram below.
Figure B-4 Virtual Media Page
3. Click Set, and see that the Virtual Media Active Image section now contains data as shown
in the diagram below.
Appendix B: Virtual Media Example
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 125
Figure B-5 Virtual Media Active Image
Step 3 – Use the Virtual Media
1. PC#2 shown in the diagram below is a Linux PC.
Figure B-6 Linux PC Window
2. Once Step 1 is done, PC#2 will detect a new USB CD drive connected to its USB as shown in
the diagram below. The CD is shown below as Fedora Core because that is the volume
name of the rescue CD (boot.iso is the ISO image of this CD).
Appendix B: Virtual Media Example
Spider™ and SpiderDuo® KVM-over-IP Device User Guide 126
Figure B-7 Linux PC Window and USB CD
3. You should be able to boot from the external USB device (boot.iso) on PC#2. Make sure that
you set BIOS to boot from the USB device.
Note: Some systems may not support USB boot.
