2: Introduction

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

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.

2: Introduction

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).)

3: Getting Started

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.

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.
