Introduction

1. Introduction

This manual describes the family of Universal Device Servers (UDS), including the UDS-10
Device Server and the UDS-10-IAP Device Server with Industrial Automation Protocols. The
UDS-10B Embedded Device Server is shown here for reference only. It is part of the UDS-10
family but is described in the Embedded Integration Kit (EIK) User Manual. For all practical
purposes, it is the same as the UDS-10 but has no external metal case.

Most of the material in this manual applies to all of the UDS-10 products. However, in some
cases there will be some features that apply to only one product. In those cases, a note will
explain the variation.

Note: In most cases UDS-10 refers to UDS-10, UDS-10-IAP and UDS-10B.

UDS-10 User Guide 1-1

Introduction

1.1 UDS-10

The UDS-10 Device Server connects serial devices to Ethernet networks using the IP
protocol family (TCP for connection-oriented stream applications and UDP for datagram
applications). A few of the different types of serial devices supported are listed below:

• Time/Attendance Clocks and Terminals

• ATM Machines

• CNC Controllers

• Data Collection Devices

• Universal Power Supply (UPS) Management Units

• Telecommunications Equipment

• Data Display Devices

• Security Alarms and Access Control Devices

• Handheld Instruments

• Modems

The UDS-10 connects these devices through a TCP data channel or through a Telnet
connection to computers or another Device Server. Datagrams can be sent by UDP.

The UDS-10 supports RS-232, RS-422/485 via its DB-25F serial port. It supports 10Mb/s
Ethernet through the RJ-45 connector. It can be configured via HTTP, SNMP, DHCP or
Telnet. It contains a Flash ROM for easy software upgrades.

UDS-10 User Guide

Introduction

1.2 UDS-10B

Note: This section is for the UDS-10B only.

The UDS-10B is the embedded version of the UDS-10, and is designed to be easily and
quickly integrated into products. The UDS-10B operates the same as the UDS-10, except the
UDS-10B has no external metal case. Serial interface is accomplished via a female DB25
(DCE) connector which provides the necessary signals for both RS232 and RS422/RS485
interfaces.

In addition, an RJ45 (10BASE-T) connector is available for Ethernet access. It will support
network speeds of 10Mbps.

The UDS-10B board comes with various power supply options:

• a power jack for 9-30 VDC or 9-24 VAC with maximum 140mA.

• power via the DB25 inputs at either the regulated +5 VDC with maximum 200mA or

the unregulated 9-30 VDC.

The UDS-10B’s well-developed IP firmware supports protocols such as ARP, UDP, TCP,
Telnet, ICMP, SNMP, BOOTP,DHCP, TFTP, AutoIP, HTTP, and custom protocols.

Note: Please see the EIK, Embedded Integration Kit user manual, 900-226, for information
on using the UDS-10B Embedded Device Server.

Introduction

1.3 UDS-10-IAP Device Server

Note: This section is for the UDS-10-IAP only.

The Lantronix Industrial Automation Platform (IAP) family of Device Servers allows a single
network and protocol to connect multiple serial devices from many vendors. IAP provides
the automation industry with a network-enabling solution using TCP/IP and standard Ethernet
networks that is vendor-independent.

By encapsulating serial data and transporting it over Ethernet, the Device Server allows
virtual serial links to be established over Ethernet and IP (TCP/IP, UDP/IP) networks. As a
result, limited distance, point-to-point, direct serial connections can be extended within the
plant, throughout the facility, or across the global enterprise. The following picture is one of
the Device Servers in the IAP family.

Figure 1 – UDS-10-IAP

Lantronix provides IAP Device Servers specifically designed for different industrial
environments.

• CoBox-DR1-IAP, with a DIN rail interface for harsh environments or alongside

controls instruments in electrical panels.

• CoBox-FL-IAP, with fiber connectivity for long cable runs or electrically hazardous

environments.

• UDS-10-IAP, a compact Device Server for use in less demanding environments.

UDS-10 User Guide

Introduction

A few examples of attached devices are:

• PLCs

• AC/DC drives

• CNC systems

• Operator panels and message displays

• Process Controls

• Instrumentation

• Power monitoring equipment

• Scales and weighing systems

• Barcode scanners

• Label printers

• Most factory floor serial devices

1.3.1 Industrial Automation Protocols

IAP Device Servers, adapted to multiple factory environments, can unite any mixture of
equipment from industrial automation vendors into a single reliable pipeline. This new and
open infrastructure opens the way for data to flow in real time from all your plant devices up
to your IT layer.

IAP Device Servers are delivered with IAP Standard Tunneling protocol and can be loaded
with industrial communication protocols. The suite of protocols include DF1 (Rockwell
Automation) and Modbus (Schneider Electric). Where the IAP Standard Tunneling protocol
is limited to exclusive, standard ASCII device-to-device connections, the industrial protocols
offer connections to other devices that require special formatting or features simultaneously.

For information about using any of the industrial communication protocols, see the user
manuals on the software CD or our web site. Protocol firmware files are also contained on the
CD and new versions are available from the Lantronix web site.

You can set up the unit using the serial port, or remotely over Ethernet using Telnet or a web
browser. The CD that comes with your Device Server includes DeviceInstaller, a Windows
based configuration software that simplifies the process of installing protocols and
configuring them for use with attached devices. IAP Device Servers use Flash memory for
maintenance-free, non-volatile storage which allows for fast system upgrades.

UDS-10 User Guide 1-5

Introduction

1.4 Network Protocols

Note: UDS-10 refers to UDS-10, UDS-10-IAP and UDS-10B except where noted.

The UDS-10 uses TCP/IP protocols for network communication. The supported standards
are: ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, AutoIP, and SNMP. For transparent
connections, TCP/IP (binary stream) or Telnet protocols are used. Firmware upgrades can be
made with the TFTP protocol.

The IP (Internet Protocol) protocol defines addressing, routing, and data-block handling over
the network. The TCP (transmission control protocol) assures that no data is lost or
duplicated, and that everything sent into the connection on one side arrives at the target
exactly as it was sent.

For typical datagram applications where devices interact with others without maintaining a
point-to-point connection, UDP datagram is used.

1.4.1 Packing Algorithm

The two available packet algorithms (which define how and when packets are sent to the
network) are software selectable. The standard algorithm is optimized for applications where
UDS-10 is used in a local environment, allowing for very small delays for single characters
while trying to keep the packet count low. The alternate packing algorithm minimizes the
packet count on the network and is especially useful for applications in routed Wide Area
Networks. Various parameters can be set in this mode to economize the serial data stream.

1.4.2 IP Address

Every active device connected to the TCP/IP network must have a unique IP address. This IP
address is used to reference a specific device, for example, to build a connection to UDS-10’s
serial port. See IP Addresses on page 10-1 for a complete description of IP Addressing.

1.4.3 Port Number

A destination IP address and a port number define every TCP connection and every UDP
datagram. A port number is necessary to address an application or a channel on a network
host. The port number can be compared to an extension on a PBX system.

A Telnet application (login to a host with an ASCII terminal) is commonly assigned TCP port
number 23. More than one Telnet connection can be established to one host using the Telnet
port; however, the other peer IP address/port number combinations must be different.

In the UDS-10, a port number can be configured on the channel (port). The UDS-10 uses this
port number for outgoing messages and incoming connections, or UDP datagrams, which are
addressed to its port number. Port 9999 (decimal) is used for remote configuration.

Getting Started

2. Getting Started

This section describes all the procedures for configuring your unit. For a short version, see
the Quick Start Guide. Go to the Lantronix web site for the latest firmware and release notes.

UDS-10 comes with Standard Tunnel Protocol and the UDS-10-IAP comes with the IAP
Standard Tunnel Protocol. Both versions are similar but cannot be interchanged. Standard
Tunneling is a serial communications protocol used by most Lantronix Device Servers. It can
be configured to Ethernet-enable most serial devices such as barcode scanners, weigh scales,
operator panels, data access devices, alpha numeric displays, and thousands of intelligent
serial devices. For UDS-10-IAP users, see Industrial Automation Protocols on page 1-5

Loading industrial protocols to a UDS-10-IAP, such as IAP Modbus Bridge, may remove the
web pages and change the configure dialogs. See the user manuals on individual protocols for
protocol specific settings and configuration dialogs. Protocol manuals are found on the
software CD. This section describes the setup and configuration dialogs for the Standard
Tunnel Protocol.

Note: The following information is based on the condition that a UDS-10 is loaded with
Standard Tunnel Protocol. The UDS-10-IAP with IAP Standard Tunnel Protocol may have
different options available.

2.1 Addresses and Port Number

2.1.1 Ethernet (MAC) Address

The Ethernet address is also referred to as the hardware address or the MAC address. The
first three bytes of the Ethernet 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.

00-20-4A-21-18-17 or 00:20:4A:21:18:17

2.1.2 Internet Protocol (IP) Address

Every device connected to an IP network must have a unique IP address. This address is used
to reference the specific unit.

UDS-10 User Guide 2-1

Getting Started

2.1.3 Port Number

Every TCP connection and every UDP datagram is defined by a destination IP address and a
port number. For example, a Telnet application commonly uses port number 23. A port
number is similar to an extension on a PBX system.

The unit 's serial channel (port) can be associated with a specific TCP/UDP port number. Port
number 9999 is reserved for access to the unit's Setup (configuration) Mode window.

2.2 Physically Connecting the Unit

The following diagram shows a typical hardware configuration for the UDS-10. Use one of
