UDS2100 User Guide 8
22:: IInnttrroodduuccttiioonn
The UDS2100 is a 2-port device server that provides a quick, simple, and costeffective 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.
UDS2100 User Guide 9
2: Introduction
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
.
UDS2100 User Guide 10
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.
2: Introduction
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).)
UDS2100 User Guide 11
Product Information Label
The product information label on the underside of the unit contains the following
information about your specific unit:
Bar code
Serial number
Product ID (name)
Product description
Hardware address (also referred to as the Ethernet or MAC address)
The first three bytes of the hardware address are fixed and read 00-20-4A, identifying
the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers
assigned to each unit.

UDS2100 User Guide 14
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
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.

UDS2100 User Guide 39
6: Setup Mode: Server Configuration
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-12-3456, 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).

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.

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.
UDS2100 User Guide 45
7: Setup Mode: Channel Configuration
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.

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.
UDS2100 User Guide 46

1. Enter a Connect Mode of 0x20 (2X), where X is 1-5. 1=start with any character,
2=with active DTR, 3=with carriage return, 4=manual connection, 5=autostart.
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.
UDS2100 User Guide 47
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 UDS2100s, 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
7: Setup Mode: Channel Configuration
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).

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.
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.

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.

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-ofsequence 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.
UDS2100 User Guide 53
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
disables the recognition of the characters. Alternatively, the unit can interpret two
characters as a sequence (see Pack Control on page 52). The default setting is 00.
7: Setup Mode: Channel Configuration
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. There is no default password.

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.

) or by using anonymous FTP
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 (U4) or
WEB1 to WEB19 for the internal Web interface.
6. Click the Upload Now button to transfer the file to the unit.

Figure 9-1. TFTP Window
After the firmware has been loaded and stored, which takes approximately 8 seconds
to complete, the unit performs a power reset.
Using TFTP: Command Line Interface
To download new firmware from a computer:
1. Enter the following from a TFTP command line interface:
tftp –i <ip address> put <local filename> <destination file name>
The following examples demonstrate the TFTP command sequence to download
the .rom file and the .cob file:
tftp –i 192.168.1.111 put UDS2100_6102.rom U4
tftp –i 192.168.1.111 put UDS2100_webm_1403.cob WEB4
2. In the Remote file name field, enter the current internal operational code (U4) or
WEB1 to WEB19 for the internal Web interface.
Recovering the Firmware Using the Serial Port and DeviceInstaller
If for some reason the firmware is damaged, you can recover the firmware file by
using DeviceInstaller to download the *.ROM file over the serial port.
To recover firmware:
1. Connect the COM interface of your PC to serial port 1 of the unit.
2. Start DeviceInstaller. If your PC has more than one network adapter, a message
displays. Select an adapter and click OK.
3. From the Tools menu, select Advanced/Recover Firmware. The Serial Port

using the network.
Entering Monitor Mode Using the Serial Port
To enter Monitor Mode locally:
1. Follow the same steps used for setting the serial configuration parameters
(see Serial Port on page 36).
2. Instead of typing three x keys, however:
a) Type zzz (or xx1) to enter Monitor Mode with network connections.
b) Type yyy (or yy1) to enter Monitor Mode without network connections.
A 0> prompt indicates that you have successfully entered Monitor Mode.
Entering Monitor Mode Using the Network Port
To enter Monitor Mode using a Telnet connection:
1. Establish a Telnet session to the configuration port (9999).
2. Type M (upper case) immediately.
A 0> prompt indicates that you have successfully entered Monitor Mode.
Monitor Mode Commands
The following commands are available in Monitor Mode. Many commands have an IP
address as an optional parameter (xxx.xxx.xxx.xxx). If you enter the IP address, the
command is applied to another unit with that IP address. If you do not enter the IP
address, the command is executed locally.
Note: All commands must be in capital letters. Responses to some of the
commands are in Intel Hex format.

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 UDS2100 is
powered up. Confirm that you are using a good network connection.

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.
When you try to enter the setup
mode on the device server using
the serial port, you get no
response.
You can ping the device server,
but not Telnet to the device
server on port 9999.
The most likely reason is
the wrong serial settings
were chosen.
The issue is most likely
something covered in the
previous problem, or
possibly, you have Caps

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.
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

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

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 DHCPassigned 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.
UDS2100 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 (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.
A: Alternative Ways to Assign an IP Address
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
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

12 1100 C
13 1101 D
14 1110 E
15 1111 F
UDS2100 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 ProgramsAccessoriesCalculator.
2. On the View menu, select Scientific. The scientific calculator displays.
3. Select Bin (Binary), and type the number to convert.
