The UDS1100 is a single-port device server that provides a quick, simple, and cost-
effective way to bring the advantages of data accessibility and remote management
to devices not currently connected to a network.
Applications
The UDS family of Device Servers allows serial devices, such as those listed below,
to connect and communicate over Ethernet networks using the IP protocol family
(TCP for connection-oriented stream applications and UDP for datagram
applications).
Security alarms
Access control devices
Fire control panels
Time/attendance clocks and terminals
ATM machines
Data collection devices
RFID readers
Universal Power Supply (UPS) management units
Telecommunications equipment
Data display devices
Virtually any asynchronous RS-232, RS422, or RS485 device
Application Examples
Using a method called serial tunneling, the UDS encapsulates serial data into
packets and transports them over Ethernet. Using two UDS units, connected by a
network, virtual serial connections can extend across a facility or around the world.

2: Introduction
UDS1100 User Guide 10
Figure 2-1. Serial Tunneling Example
The Com Port Redirector software included on the product CD simplifies the
integration process by extending the functionality of COM-port-based Windows™
applications. Virtual COM ports, mapped to remote device servers on the network,
can replace direct serial connections.
Figure 2-2. Direct TCP/IP or Redirector Configuration
Note: For step-by-step instructions on configuring the UDS for serial tunneling or for
use with the Com Port Redirector, see UDS Configuration Tutorials on the Lantronix
web site: www.lantronix.com/support.
2: Introduction
2: Introduction
UDS1100 User Guide 11
Protocol Support
The UDS uses the Internet Protocol (IP) for network communications and the
Transmission Control Protocol (TCP) to assure that no data is lost or duplicated and
that everything sent to the connection arrives correctly at the target.
Supported protocols include:
ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications.
TCP, UDP, and Telnet for connections to the serial port.
TFTP for firmware updates.
IP for addressing, routing, and data block handling over the network.
User Datagram Protocol (UDP) for typical datagram applications in which
devices interact with other devices without a point-to-point connection.
Additional Features
Modem Emulation: In modem emulation mode, the UDS can replace dial-up
modems. The unit accepts modem AT commands on the serial port and then
establishes a network connection to the end device. This arrangement leverages
network connections and bandwidth to eliminate dedicated modems and phone lines.
Built-in Web Server: The UDS includes a built-in web server for configuring the unit
and displaying operating and troubleshooting information on the attached links to
online support.
Configuration Methods
After installation, the UDS requires configuration. For the unit to operate correctly on
a network, it must have a unique IP address on the network. There are three basic
methods for logging into the UDS and assigning IP addresses and other configurable
settings:
DeviceInstaller: Configure the IP address and other network settings on the UDS
using a Graphical User Interface (GUI) on a PC attached to a network.
(See Assigning the IP Address: DeviceInstaller on page 16.)
Web-Manager: Through a web browser, configure the UDS settings using the
Lantronix Web-Manager. (See 4: Configuration Using Web-Manager.)
Serial and Telnet Ports: Use Setup Mode, a command line interface. There are two
approaches to accessing Setup Mode: making a Telnet connection to the network
port (9999) or connecting a terminal (or a PC running a terminal emulation program)
to the unit’s serial port. (See 5: Configuration via Telnet or Serial Port (Setup Mode).)

Required Information
Before configuring the UDS, have the following information available:
Hardware Address
Take note of the unit’s hardware address (also known as the Ethernet or MAC
address). It is on the product label, in the format: 00-20-4a-XX-XX-XX, where the XXs
are unique numbers assigned to the product (see Product Information Label on page
12).
Hardware Address: 00-20-4a-_____-_____-_____
IP Address
The UDS must have a unique IP address on your network. This address references
the specific unit. By default, the unit is DHCP-enabled and automatically assigned an
IP address on DHCP-enabled networks. If you are assigning a static IP address, the
systems administrator generally provides the IP address, subnet mask, and gateway.
Note: The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP,
and AutoIP. When the units boots, it sends a DHCP broadcast to try and get
an IP address. If it receives no reply from a DHCP server, the UDS tries
BOOTP. If the UDS does not receive a response from BOOTP, it reverts to
an AutoIP address.
IP Address: _______ _______ _______ _______
Subnet Mask: _______ _______ _______ _______
Gateway: _______ _______ _______ _______
You have several options for assigning an IP address and related network settings to
your unit. This chapter provides information about using the DeviceInstaller (graphical
user interface) and serial port login (command line interface) methods.
Note: For information about other methods of assigning the IP address, such
as DHCP, AutoIP, ARP, and Telnet, see A: Alternative Ways to Assign an IP
Address.

You must configure the unit so it can communicate on a network with your serial
device. For example, you must set the way the unit will respond to serial and network
traffic, how it will handle serial packets, and when to start or close a connection.
The unit’s configuration is stored in nonvolatile memory and is retained without
power. You can change the configuration at any time. The unit performs a reset after
you change and store the configuration.

This chapter explains how to configure the network settings.
Note: Current values display in parentheses.
Server Configuration (Option 0)
The unit’s basic network parameters display when you select Server configuration
(option 0). The IP Address, Set Gateway IP Address, and Netmask fields display
the current values.
Figure 6-1. Network Settings
IP Address : (000) .(000) .(000) .(000)
Set Gateway IP Address (N)
Netmask: Number of Bits for Host Part (0=default) (0)
Change telnet config password (N)
IP Address
If DHCP is not used to assign IP addresses, enter the IP address manually. The IP
address must be set to a unique value in the network. Enter each octet and press
Enter between each section. The current value displays in parentheses.
IP Address : (000) (000) (000) (000) _
If DHCP is used, the third octet of the IP address sets the BootP/DHCP/AutoIP
options. The following table shows the bits you can manually configure to force the
UDS1100 to disable AutoIP, DHCP, or BootP. To disable an option, set the
appropriate bit.
Table 6-1. BootP/DHCP/AutoIP options
Options Bit Value
AutoIP 0 1
DHCP 1 2
BootP 2 4
For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are
disabled; only DHCP is enabled. (The value 5 results from adding the binary
equivalents of 0 and 2.) This is the most common setting when using DHCP.
Set Gateway IP Address
The gateway address, or router, allows communication to other LAN segments. The
gateway address should be the IP address of the router connected to the same LAN
segment as the unit. The gateway address must be within the local network. The

Netmask: Number of Bits for Host Part
A netmask defines the number of bits taken from the IP address that are assigned for
the host part.
Netmask: Number of Bits for Host Part (0=default) (0) _
Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits
The unit prompts for the number of host bits to be entered, then calculates the
netmask, which appears in standard decimal-dot notation (for example,
255.255.255.0) when the saved parameters display. The default setting is 0.
Table 6-2. Standard IP Network Netmasks

Change Telnet Configuration Password
Setting the Telnet configuration password prevents unauthorized access to the setup
menu through a Telnet connection to port 9999 or through web pages. The password
must have 4 characters. The default setting is N (No).
Figure 6-2. Change Telnet Configuration Password

An enhanced password setting (for Telnet access only) of 16 characters is available
under Security Settings (Option 6) on page 56.
Note: You do not need a password to access the Setup Mode window by a
serial connection.
DHCP Name
If a DHCP server has automatically assigned the IP address and network settings,
you can discover the unit by using the DeviceInstaller network search feature or
Monitor Mode (see 10: Monitor Mode).
Note: When you enter Monitor Mode from the serial port with network
connection enabled and issue the NC (Network Communication) command,
you see the unit’s IP configuration.
6: Setup Mode: Server Configuration Change DHCP device name (not set) 2 (N) y
6: Setup Mode: Server Configuration
UDS1100 User Guide 39
There are three methods for assigning DHCP names to the unit.
Default DHCP Name: If you do not change the DHCP name, and you are
using an IP of 0.0.0.0, then the DHCP name defaults to XX.XX.XX.XX
(XXXXXX is the last 6 digits of the MAC address shown on the label on the
bottom/side of the unit). For example, if the MAC address is 00-20-4A-12-34-
56, then the default DHCP name is C123456.
Custom DHCP Name: You can create your own DHCP name. If you are using
an IP address of 0.0.0.0, then the last option in Server configuration is Change
DHCP device name. This option allows you to change the DHCP name to an
alphanumeric name (LTX in our example).
Change DHCP device name (not set) ? (N) Y
Enter new DHCP device name : LTX
Numeric DHCP Name: You can change the DHCP name by specifying the last
octet of the IP address. When you use this method, the DHCP name is LTXYY
where YY is what you chose for the last octet of the IP address. If the IP
address you specify is 0.0.0.12, then the DHCP name is LTX12. This method
only works with 2 digit numbers (01-99).

This chapter explains how to configure the serial port.
Notes:
Current values display in parenthesis.
You must enter some values in hexadecimal notation. (See B: Binary to
Hexadecimal Conversions.)
Channel 1 (Option 1)
Select Channel 1 (option 1) from the Change Setup menu to define how the serial
port responds to network and serial communications. The following sections describe
the configurable parameters within the Channel configuration menu.
Figure 7-1. Serial Port Settings
Baudrate
The unit and attached serial device, such as a modem, must agree on a speed or
baud rate to use for the serial connection. Valid baud rates are 300, 600, 1200, 2400,
4800, 9600 (default), 19200, 38400, 57600, 115200, and 230400 baud.

Port Number
The setting represents the source port number in TCP connections. It is the number
that identifies the channel for remote initiating connections.
Port No (10001) ? _
The default setting for Port 1 is 10001. The range is 1-65535, except for the following
reserved port numbers:
Table 7-4. Reserved Port Numbers
Warning: We recommend that you not use the reserved port numbers
for this setting as incorrect operation may result.
Use Port 0 for the outgoing local port to change with each connection. The port range
is 50,000-59,999. Each subsequent connection increments the number by 1 (it wraps
back around to 50,000).
Only use this automatic port increment feature to initiate a connection using TCP. Set
the port to a non-zero value when the unit is in a passive mode or when using UDP
instead of TCP.
Connect Mode
Connect Mode defines how the unit makes a connection, and how it reacts to
incoming connections over the network.
ConnectMode (C0) ? _
Enter Connect Mode options in hexadecimal notation. The default setting is C0.

b) Response
Character Response A single character is transmitted to the serial port when there is a
change in connection state:
C = connected, D = disconnected, N = host unreachable.
This option is overridden when the Active Start Modem Mode
or Active Start Host List is in effect. Default setting is Nothing
(quiet).
c) Active Startup
No Active Startup Does not attempt to initiate a connection under any
circumstance. Default setting.
With Any Character Attempts to connect when any character is received from the
serial port.
With DTR Active Attempts to connect when the DTR input changes from not
asserted to asserted.
With a Specific Start
Character
Attempts to connect when it receives a specific start character
from the serial port. The default start character is carriage return.
Manual Connection Attempts to connect when directed by a command string
received from the serial port. The first character of the command
string must be a C (ASCII 0x43), and the last character must be
either a carriage return (ASCII 0x0D) or a line feed (0x0A). No
blanks or space characters may be in the command string.
Between the first and last command string characters must be a
full or partial destination IP address and may be a destination
port number.
The IP address must be in standard decimal-dot notation and
may be a partial address, representing the least significant 1, 2,
or 3 bytes of the remote IP address. The period is required
between each pair of IP address numbers.
If present, the port number must follow the IP address, must be
presented as a decimal number in the range 1-65535, and must
be preceded by a forward slash (ASCII 0x2F). The slash
separates the IP address and the port number. If you omit the
port number from a command string, the internally stored remote
port number starts a connection.
If a partial IP address is presented in a command string, it is
interpreted to be the least significant bytes of the IP address and
uses the internally stored remote IP address to provide the most
significant bytes of the IP address. If the IP address entered is
0.0.0.0/0, the device server enters Monitor Mode.
For example, if the remote IP address already configured in the
unit is 129.1.2.3, then an example command string would be
C3/7. (This would connect to 129.1.2.3 and port 7.) You may
also use a different ending for the connection string. For
example, C50.1/23 would connect you to 129.1.50.1 and port 23.

Autostart (Automatic
Connection)
If you enable Autostart, the unit automatically connects to the
remote IP address and remote port specified when the firmware
starts.
Hostlist If you enable this option, the device server scrolls through the
hostlist until it connects to a device listed in the hostlist table.
Once it connects, the unit stops trying to connect to any others. If
this connection fails, the unit continues to scroll through the table
until it is able to connect to another IP in the hostlist.
Hostlist supports a minimum of 1 and a maximum of 12 entries.
Each entry contains the IP address and the port number.
The hostlist is disabled for Manual and Modem Modes. The unit
does not accept a data connection from a remote device when
the hostlist option is enabled.
Figure 4-7. Hostlist Option
7: Setup Mode: Channel Configuration
7: Setup Mode: Channel Configuration
UDS1100 User Guide 46
To enable the hostlist:
1. Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you
a list of current entries already defined in the product.
2. To delete, modify, or add an entry, select Yes. If you enter an IP address of
0.0.0.0, that entry and all others after it are deleted.
3. After completing the hostlist, repeat the previous step if necessary to edit the
hostlist again.
4. For Retrycounter, enter the number of times the Lantronix unit should try to
make a good network connection to a hostlist entry that it has successfully
ARPed. The range is 1-15, with the default set to 3.
5. For Retrytimeout, enter the number of seconds the unit should wait before
failing an attempted connection. The time is stored as units of milliseconds in the
range of 1-65535. The default setting is 250.
d) Datagram Type
Directed UDP When selecting this option, you are prompted for the Datagram type.
Enter 01 for directed or broadcast UDP.
When the UDP option is in effect, the unit never attempts to initiate a
TCP connection because it uses UDP datagrams to send and receive
data.
e) Modem Mode
In Modem (Emulation) Mode, the unit presents a modem interface to the attached
serial device. It accepts AT-style modem commands and handles the modem signals
correctly.
Normally, there is a modem connected to a local PC and a modem connected to a
remote machine. A user must dial from the local PC to the remote machine,
accumulating phone charges for each connection. Modem Mode allows you to
replace modems with UDS1100s, and to use an Ethernet connection instead of a
phone call. By not having to change communications applications, you avoid
potentially expensive phone calls.
To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full
verbose), D7 (echo with numeric response), CF (modem responses only, numeric
response), or CE (modem responses only, full verbose).
Note: If the unit is in Modem Mode, and the serial port is idle, the unit can
still accept network TCP connections to the serial port if Connect Mode is set
to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric
response, CF (modem responses only, numeric response), or CE (modem
responses only, full verbose).
Without Echo In Modem Mode, echo refers to the echo of all of the characters
entered in command mode; it does not mean to echo data that is
transferred. Quiet Mode (without echo) refers to the modem not
sending an answer to the commands received (or displaying what
was typed).

4 Error
Received commands must begin with the two-character sequence AT and be
terminated with a carriage return character.
The unit ignores any character sequence received not starting with AT, and only
recognizes and processes single AT-style commands. The unit treats compound AT
commands as unrecognized commands.
If the Full Verbose option is in effect, the unit responds to an unrecognized
command string that is otherwise formatted correctly (begins with AT and ends with
carriage return) with the "OK" message and takes no further action.
If the Numeric Response option is in effect, the unit responds to an unrecognized
command string that is otherwise formatted correctly with a "0" message and takes
no further action.
When an active connection is in effect, the unit transfers data and does not process
commands received from the serial interface.
When a connection is terminated or lost, the unit reverts to command mode.
7: Setup Mode: Channel Configuration
7: Setup Mode: Channel Configuration
UDS1100 User Guide 48
When an active connection is in effect, the unit terminates the connection if it
receives the following sequence from the attached serial device:
No serial data is received for one second.
The character sequence +++ is received, with no more than one second
between each two characters.
No serial data is received for one second after the last + character. At this time,
the unit responds affirmatively per the selected echo/response mode.
The character string ATH is received, terminated with a carriage return. The
unit responds affirmatively according to the selected echo/response mode and
drops the network connection. The serial interface reverts to accepting
command strings.
If this sequence is not followed, the unit remains in data transfer mode.

Alternate Packing Algorithm (Pack Control)
Enable 1
Pack Control
The packing algorithms define how and when packets are sent to the network. The
standard algorithm is optimized for applications in which the unit is used in a local
environment, allowing for very small delays for single characters, while keeping the
packet count low. The alternate packing algorithm minimizes the packet count on the
network and is especially useful in applications in a routed Wide Area Network
(WAN). Adjusting parameters in this mode can economize the network data stream.
Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not
need specific functions.
Note: All bit positions in the table that are blank represent “don’t care” bits for
that particular option, which can be set to either a 0 or 1 value.

Packing Interval
Packing Interval defines how long the unit should wait before sending accumulated
characters. This wait period is between successive network segments containing
data. For alternate packing, the default interval is 12 ms.
Trailing Characters
In some applications, CRC, Checksum, or other trailing characters follow the end-of-
sequence character; this option helps to adapt frame transmission to the frame
boundary. The default setting is 00 (none).
Send Characters
If 2-Byte Send Character Sequence is enabled, the unit interprets the
sendchars as a 2-byte sequence; if this option is not enabled, the unit
interprets them independently. The default setting is 0 (disabled).
If Send Immediately After Characters is not set, any characters already in
the serial buffer are included in the transmission after a "transmit" condition is
found. If this option is set, the unit sends immediately after recognizing the
transmit condition (sendchar or timeout). The default setting is 0.
Note: A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The unit drops the connection if there
is no activity on the serial line before the set time expires. Enter time in the format
mm:ss, where m is the number of minutes and s is the number of seconds.
DisConnTime (00:00) ?:
To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds
(99 minutes, 59 seconds). Default setting is 0.
Send Characters
Enter up to two characters in hexadecimal representation in sendchar.
SendChar 1 (00) ? _
SendChar 2 (00) ? _
If the unit receives a character on the serial line that matches one of these
characters, it sends the character immediately, along with any awaiting characters, to
the TCP connection. This action minimizes the response time for specific protocol
characters on the serial line (for example, ETX, EOT). Setting the first sendchar to 00
7: Setup Mode: Channel Configuration
7: Setup Mode: Channel Configuration
UDS1100 User Guide 53
disables the recognition of the characters. Alternatively, the unit can interpret two
characters as a sequence (see Pack Control on page 51). The default setting is 00.
Telnet Terminal Type
This parameter displays only if you enabled the terminal type option in Disconnect
Mode. With this option enabled, you can use the terminal name for the Telnet
terminal type. Enter only one name.
With terminal type option enabled, the unit also reacts to the EOR (end of record) and
binary options, useful for applications like terminal emulation to IBM hosts.
Channel (Port) Password
This parameter appears only if the channel (port) password option is enabled in
Disconnect Mode. With this option enabled, you can set a password on the serial
port. The default setting is all 0s.

Obtaining Firmware
You can obtain the most up-to-date firmware and release notes for the unit from the
Lantronix web site (www.lantronix.com) or by using anonymous FTP
(ftp.lantronix.com).
Reloading Firmware
There are several ways to update the unit's internal operational code (*.ROM): using
DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also
update the unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.
Here are typical names for those files. Check the Lantronix web site for the latest
versions and release notes.
Table 9-1. Firmware Files
ROM File COB
uds1100_6101.rom uds1100_webm_1401.cob
Please refer to the DeviceInstaller online Help for information about reloading
firmware using DeviceInstaller. The other methods are discussed below.
Using TFTP: Graphical User Interface
To download new firmware from a computer:
1. Use a TFTP client to send a binary file to the unit (*.ROM to upgrade the unit's
internal operational code and *.COB to upgrade its internal Web interface).
Note: TFTP requires the .ROM (binary) version of the unit's internal
operational code.
2. In the TFTP server field, enter the IP address of the unit being upgraded.
3. Select Upload operation and Binary format.
4. Enter the full path of the firmware file in the Local file name field.
5. In the Remote file name field, enter the current internal operational code (U3) or
WEB1 to WEB19 for the internal Web interface.
6. Click the Upload Now button to transfer the file to the unit.

This chapter discusses how you can diagnose and fix errors quickly without having to
contact a dealer or Lantronix. It helps to connect a terminal to the serial port while
diagnosing an error to view summary messages that may display. When
troubleshooting, always ensure that the physical connections (power cable, network
cable, and serial cable) are secure.
Note: Some unexplained errors might be caused by duplicate IP addresses on the
network. Make sure that your unit's IP address is unique.
When troubleshooting the following problems, make sure that the UDS1100 is
powered up. Confirm that you are using a good network connection.
LEDs
The UDS has the following LEDs, which help you diagnose problems.
Power LED (green)
Ethernet 10/100 Link (yellow = 10 Mb/green = 100 Mb)
Ethernet Half/Full Duplex Activity (yellow = Half Duplex/green = Full Duplex)
Diagnostic (red)
Status (green)
Simultaneously lit Diagnostic (red) and Status (green) LEDs mean something is
wrong. If the Diagnostic LED is lit or blinking, count the number of times the Status
LED blinks between its pauses. The following table explains the LED functions:

When you issue the ARP –S
command in Windows, the "ARP
entry addition failed: 5" message
displays.
Your currently logged-in
user does not have the
correct rights to use this
command on this PC.
Have someone from your IT
department log you in with
sufficient rights.
When you attempt to assign an IP
address to the unit by the ARP
method, the "Press Enter to go into
Setup Mode" error "(described
below) message displays. Now
when you Telnet to the device
server, the connection fails.
When you Telnet to port 1
on the device server, you
are only assigning a
temporary IP address.
When you Telnet into port
9999 and do not press
Enter quickly, the device
server reboots, causing it to
lose the IP address.
Telnet back to Port 1. Wait for it to
fail, then Telnet to port 9999 again.
Make sure you press Enter
quickly.
When you Telnet to port 9999, the
"Press Enter to go into Setup Mode"
message displays. However,
nothing happens when you press
Enter, or your connection is closed.
You did not press Enter
quickly enough. You only
have 5 seconds to press
Enter before the connection
is closed.
Telnet to port 9999 again, but
press Enter as soon as you see
the "Press Enter to go into Setup
Mode" message.
You may have entered the
Ethernet address incorrectly
with the ARP command.
Confirm that the Ethernet address
that you entered with the ARP
command is correct. The Ethernet
address may only include numbers
0-9 and letters A-F. In Windows
and usually in Unix, the segments
of the Ethernet address are
separated by dashes. In some
forms of Unix, the Ethernet
address is segmented with colons.
The IP address you are
trying to assign is not on
your logical subnet.
Confirm that your PC has an IP
address and that it is in the same
logical subnet that you are trying to
assign to the device server.
When you Telnet to port 1 to assign
an IP address to the device server,
the Telnet window does not
respond for a long time.
The device server may not
be plugged into the network
properly.
Make sure that the Link LED is lit.
If the Link LED is not lit, then the
device server is not properly
plugged into the network.

Problem/Message Reason Solution
When you try to assign an IP with
DeviceInstaller, you get the
following :
"No response from device!
Verify the IP, Hardware
Address and Network Class.
Please try again."
The cause is most likely
one of the following:
The hardware address you
specified is incorrect.
The IP address you are
trying to assign is not a
valid IP for your logical
subnet.
You did not choose the
correct subnet mask.
Double-check the parameters that
you specified.
Note: You cannot assign an IP
address to a device server through
a router.
The device server is not
communicating with the serial
device to which it is attached.
The most likely reason is
the wrong serial settings
were chosen.
The serial settings for the serial
device and the device server must
match. The default serial settings
for the device server are RS-232,
9600 baud, 8 character bits, no
parity, 1 stop bit, no flow control.
When you try to enter the setup
mode on the device server using
the serial port, you get no response.
The issue is most likely
something covered in the
previous problem, or
possibly, you have Caps
Lock on.
Double-check everything in the
problem above. Confirm that Caps
Lock is not on.
You can ping the device server, but
not Telnet to the device server on
port 9999.
There may be an IP
address conflict on your
network
You are not Telneting to
port 9999.
The Telnet configuration
port (9999) is disabled
within the device server
security settings.
Turn the device server off and then
issue the following commands at
the DOS prompt of your computer:
ARP -D X.X.X.X (X.X.X.X is the IP
of the device server).
PING X.X.X.X (X.X.X.X is the IP of
the device server).
If you get a response, then there is
a duplicate IP address on the
network. If you do not get a
response, use the serial port to
verify that Telnet is not disabled.
With DeviceInstaller, you get the
Wrong Password error when you try
to upgrade the firmware.
The file you are attempting
to load is the incorrect
firmware file for the UDS.
Download the correct firmware file
from the Lantronix website.

Problem/Message Reason Solution
The device server appears to be set
up correctly, but you are not
communicating with your device
attached to the device server
across the network.
If you are sure that the
serial port setting is correct,
then you may not be
connecting to the correct
socket of the device server.
Another possibility is that
the device server is not set
up correctly to make a good
socket connection to the
network.
You can check to see whether
there is a socket connection to or
from the UDS by looking at the
Status LED.
If the Status LED is blinking
consistently, then there is a good
socket connection.
If the Status LED is solid green,
then the socket connection does
not exist. Use the Connect Mode
option C0 for making a connection
to the UDS from the network. Use
Connect Mode option C1 or C5 for
a connection to the network from
the UDS.
When connecting to the Web-
Manager within the device server,
the "No Connection With The
Device Server" message displays.
Your computer is not able
to connect to port 30718
(77FEh) on the device
server.
Make sure that port 30718 (77FEh)
is not blocked with any router that
you are using on the network. Also,
make sure that port 77FEh is not
disabled within the Security
settings of the device server.

Earlier chapters describe how to assign a static IP address using DeviceInstaller,
Web Manager, and Setup Mode (through a Telnet or serial connection). This section
covers other methods for assigning an IP address over the network.
DHCP
The unit ships with a default IP address of 0.0.0.0, which automatically enables
DHCP. If a DHCP server exists on the network, it provides the unit with an
IP address, gateway address, and subnet mask when the unit boots up.
You can use the DeviceInstaller software to search the network for the DHCP-
assigned IP address and add it to the list of devices retrieved.
Note: This DHCP address does not appear in the unit’s Setup Mode or in
Web Manager. You can determine your unit’s DHCP-assigned IP address in
Monitor Mode. When you enter Monitor Mode from the serial port with
network connection enabled and issue the NC (Network Communication)
command, you see the unit’s IP configuration.
AutoIP
The unit ships with a default IP address of 0.0.0.0, which automatically enables
Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain
an IP address automatically in smaller networks that may not have a DHCP server. A
range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly
reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses
over the Internet.
If your unit cannot find a DHCP server, and you have not manually assigned an
IP address to it, the unit automatically selects an address from the AutoIP
reserved range. Then, your unit sends out a (ARP) request to other nodes on
the same network to see whether the selected address is being used.
If the selected address is not in use, then the unit uses it for local subnet
communication.
If another device is using the selected IP address, the unit selects another
address from the AutoIP range and reboots. After reboot, the unit sends out
another ARP request to see if the selected address is in use, and so on.
AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the
network. If it finds a DHCP server, the unit switches to the DHCP server-provided
address and reboots.
Note: If a DHCP server is found, but it denies the request for an IP address,
the unit does not attach to the network, but waits and retries.
AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting
enables DHCP but disables AutoIP.
A: Alternative Ways to Assign an IP Address
UDS1100 User Guide 76
BOOTP
Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a
specific duration of time.
ARP and Telnet
If the unit has no IP address, you can use Address Resolution Protocol (ARP)
method from UNIX and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
1. On a UNIX or Windows-based host, create an entry in the host's ARP table
using the intended IP address and the hardware address of the unit (on the
product label on the bottom of the unit).
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)
Note: For the ARP command to work on Windows 95, the ARP table
on the PC must have at least one IP address defined other than its
own.
2. If you are using Windows 95, type ARP -A at the DOS command prompt to
verify that there is at least one entry in the ARP table. If the local machine is
the only entry, ping another IP address on your network to build a new entry
in the ARP table; the IP address must be a host other than the machine on
which you are working. Once there is at least one additional entry in the ARP
table, use the following command to ARP an IP address to the unit:
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
3. Open a Telnet connection to port 1. The connection fails quickly, but the unit
temporarily changes its IP address to the one designated in this step.
telnet 191.12.3.77 1
4. Open a Telnet connection to port 9999, and press Enter within five seconds
to go into Setup Mode. If you wait longer than five seconds, the unit reboots.
telnet 191.12.3.77 9999
Note: The IP address you just set is temporary and reverts to the default
value when the unit’s power is reset, unless you configure the unit with a
static IP address and store the changes permanently.

Many of the unit’s configuration procedures require assembling a series of options
(represented as bits) into a complete command (represented as a byte). Convert the
resulting binary value to a hexadecimal representation.
Converting Binary to Hexadecimal
Following are two simple ways to convert binary numbers to hexadecimals.
Conversion Table
Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A
(for 10), B (for 11), etc. To convert a binary value (for example, 0100 1100) to a
hexadecimal representation, the upper and lower four bits are treated separately,
resulting in a two-digit hexadecimal number (in this case, 4C). Use the following table
to convert values from binary to hexadecimal.
Decimal Binary Hex
0 0000 0
1 0001 1
2 0010 2
3 0011 3
4 0100 4
5 0101 5
6 0110 6
7 0111 7
8 1000 8

13 1101 D
14 1110 E
15 1111 F
B: Binary to Hexadecimal Conversions
UDS1100 User Guide 78
Scientific Calculator
Another simple way to convert binary to hexadecimals is to use a scientific calculator,
such as the one available on Windows’ operating systems. For example:
1. On the Windows’ Start menu, click ProgramsÆAccessoriesÆCalculator.
2. On the View menu, select Scientific. The scientific calculator displays.
3. Select Bin (Binary), and type the number to convert.
4. Click Hex. The hexadecimal value displays.
