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 seri al 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.

Assigning the IP Address: DeviceInstaller on page 16.)

(See

Web Manager: Through a web browser, configure the UDS settings using the

Lantronix Web Manager. (See

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

4: Configuration Using Web Manager.)

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.

2: Introduction for more information

11: Troubleshooting and

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.

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.

In this chapter, we describe how to configure the UDS2100 using Web Manager,
Lantronix’s browser-based configuration tool. (For information on using Setup Mode,
