2: Introduction
This chapter introduces the Lantronix EDS family of device servers. It provides an
overview of the products, lists their key features, and describes the applications for which
they are suited.
EDS is a unique, hybrid Ethernet terminal and multi-port device server product designed
to remotely access and manage virtually all of your IT/networking equipment and servers,
as well as edge devices such as medical equipment, kiosks, POS/retail terminals,
security equipment and much more.
EDS device servers contain all the components necessary to deliver full network
connectivity to virtually any kind of serial device, a reliable TCP/IP protocol stack, and a
variety of remote management capabilities. They boast an innovative design and run on
Lantronix’s leading-edge Evolution OS™, our powerful real-time networking operating
system that delivers an unprecedented level of intelligence and security to networked
equipment.
Delivering a data center-grade, programmable device computing and networking platform
for integrating “edge” equipment into the enterprise network, rack-mountable EDS models
are available in 8, 16, and 32 port configurations.
EDS4100 Overview
The EDS4100 is a compact, easy-to-use device server that gives you the ability to
network-enable asynchronous RS-232 and RS-422/485 serial devices. It can deliver fully
transparent RS-232/422 point-to-point connections and RS-485 multi-drop connections
without requiring modifications to existing software or hardware components in your
application.
Note: RS-485 circuits support 32 full-load devices or 128 quarter-load devices.
Each EDS4100 RS-485 port, however, counts as one device, leaving up to 31
full-load or 127 quarter-load devices that can be connected to the RS-485 circuit.
The EDS4100 device server supports the Power-over-Ethernet (PoE) standard.
With PoE, power is supplied to the EDS over the Ethernet cable, by either an
Ethernet switch or a midspan device. Being able to draw power through the
Ethernet cable eliminates power supply and cord clutter. It also allows the EDS to
be located in areas where power is not typically available.
Ports 1 through 4 support RS-232 devices.
Ports 1 and 3 also support RS-422/485 devices.

EDS Device Servers User Guide 15
2: Introduction
Comprehensive troubleshooting tools
Web-Based Configuration and Troubleshooting
Built upon popular Internet-based standards, the EDS enables users to configure,
manage, and troubleshoot efficiently through a simplified browser-based interface that
can be accessed anytime from anywhere. All configuration and troubleshooting options
are launched from a well-organized, multi-page interface. Users can access all
functionality via a Web browser, allowing them flexibility and remote access. As a result,
users can enjoy the twin advantages of decreased downtime (based on the
troubleshooting tools) and the ability to implement configuration changes easily (based
on the configuration tools).
In addition, users can load their own Web pages onto the EDS to facilitate monitoring and
control of their own serial devices that are attached to the EDS.
Command-Line Interface (CLI)
Making the edge-to-enterprise vision a reality, the EDS with the Evolution OS™ uses
industry-standard tools for configuration, communication, and control. For example, the
Evolution OS™ uses a Cisco
similar to that used by data center equipment such as routers and hubs.

-like command line interface (CLI) whose syntax is very
SNMP Management
The EDS supports full SNMP management, making it ideal for applications where device
management and monitoring are critical. These features allow networks with SNMP
capabilities to correctly diagnose and monitor EDS device servers.
XML-Based Architecture and Device Control
XML is a fundamental building block for the future growth of M2M networks. The EDS
supports XML-based configuration setup records that makes device configuration
transparent to users and administrators. The XML is easily editable with a standard text
or XML editor.
Really Simple Syndication (RSS)
The EDS supports Really Simple Syndication (RSS), a rapidly emerging technology for
streaming and managing on-line content. RSS feeds all the configuration changes that
occur on the device. The feed is then read (polled) by an RSS aggregator. More powerful
than simple email alerts, RSS uses XML as an underlying Web page transport and adds
intelligence to the networked device while not taxing already overloaded email systems.
Enterprise-Grade Security
Without the need to disable any features or functionality, the Evolution OS™ provides the
EDS the highest level of security possible. This ‘data center grade’ protection ensures
that each device on the M2M network carries the same level of security as traditional IT
networking equipment in the corporate data center.
With built-in SSH and SSL, secure communications can be established between the EDS
serial ports and the remote end device or application. By protecting the privacy of serial
data being transmitted across public networks, users can maintain their existing
EDS Device Servers User Guide 16
2: Introduction
investment in serial technology, while taking advantage of the highest data-protection
levels possible.
SSH and SSL can:
Verify the data received came from the proper source
Validate that the data transferred from the source over the network has not
changed when it arrives at its destination (shared secret and hashing)
Encrypt data to protect it from prying eyes and nefarious individuals
Provide the ability to run popular M2M protocols over a secure SSH connection
In addition to keeping data safe and accessible, the EDS has robust defenses to hostile
Internet attacks such as denial of service (DoS), which can be used to take down the
network. Moreover, the EDS cannot be used to bring down other devices on the network.
The EDS can be used with Lantronix’s Secure Com Port Redirector (SCPR) to encrypt
COM port-based communications between PCs and virtually any electronic device.
SCPR is a Windows application that creates a secure communications path over a
network between the computer and serial-based devices that are traditionally controlled
via a COM port. With SCPR installed at each computer, computers that were formerly
“hard-wired” by serial cabling for security purposes or to accommodate applications that
only understood serial data can instead communicate over an Ethernet network or the
Internet.
The EDS also supports a variety of popular cipher technologies including:
Advanced Encryption Standard (AES)
Triple Data Encryption Standard (3DES)
RC4
Hashing algorithms such as Secure Hash Algorithm (SHA-1) and MD5
Troubleshooting Capabilities
The EDS offers a comprehensive diagnostic toolset that lets you troubleshoot problems

Applications
EDS device servers deliver simple, reliable, and cost-effective network connectivity for all
your serial devices and address the growing need to connect individual devices to the
network over industry-standard Ethernet connections. The EDS is ideal for a variety of
applications, including:
Building automation/security
Industrial automation
Medical/healthcare
Retail automation/point-of-sale
Console management
Traffic management
Building Automation/Security
Automating, managing, and controlling many different aspects of a building is possible
with the EDS. It can overcome the hurdle of stand-alone networks or individual control
systems that are not able to communicate with each other, and not able to share vital
data, in a cost effective way.
2: Introduction
The EDS can also be used to manage equipment and devices centrally over a new or
existing Ethernet network to improve the safety and comfort of building occupants, while
lowering heating, ventilating, air conditioning (HVAC), lighting, and overall energy
operating costs through centralized management and monitoring.
Industrial Automation
Today’s manufacturing facilities face the common challenges of productivity
improvements, inventory management, and quality control. From warehouse to
automotive environments, the need to attach the following devices, whether new or
legacy, continues to grow:
Programmable Logic Controllers (PLCs), Computer Numeric Control and Direct
Numeric Control (CNC/DNC) equipment, process and quality-control equipment
Pump controllers
Bar-code readers and scanners, operator displays, scales, and weighing stations
Printers, machine-vision systems, and other types of manufacturing equipment
The EDS is well suited to deliver network connectivity to all of these devices.
Medical/Healthcare
Hospitals, clinics, and laboratories face rapidly growing needs to deliver medical
information accurately, quickly, and easily, whether at bedside, the nurse’s station, or
anywhere in the facility. The goal to improve healthcare services, however, is balanced
with the need to keep the bottom line from exceeding already constrained budgets.
The EDS can network enable medical equipment and devices using the hospital’s
existing Ethernet network to improve patient care and slash operating costs. This allows
EDS Device Servers User Guide 18
2: Introduction
medical staff members to easily monitor and control equipment over the network, whether
it is located at the point of care, in a laboratory, or somewhere else in the building, all
resulting in improved quality of service and reduced operational costs.
Retail Automation/Point-of-Sale
Having the right solution in the store to manage deliveries, track orders, and keep pricing
current are all improvements that the EDS can offer to make retail operations more
successful. From big to small, one store to thousands of outlets, the EDS can empower
point-of-sale (POS) devices to share information across the network effectively.
With the EDS, retailers can increase and streamline productivity quickly and easily by
network-enabling serial devices like card swipe readers, bar-code scanners, scales, cash
registers, and receipt printers.
Terminal Server/Console Management
Remote offices can have routers, PBXs, servers and other networking equipment that
require remote management from the corporate facility. The EDS easily attaches to the
serial ports on a server, Private Branch Exchange (PBX), or other networking equipment
to deliver central, remote monitoring and management capability.
With the menu system on the EDS, connections to the console ports of the attached
devices as well as Ethernet hosts, such as Unix servers or another EDS, can easily be
picked from a user-defined menu. This allows console ports across multiple networks to
be accessed from one EDS.
Traffic Management
With the ubiquity of Ethernet networks, managing cities over Ethernet is now within
reach. The EDS provides an easy conversion from serial ports on traffic cameras,
billboards, and traffic lights to Ethernet. The EDS obviates the need for long-haul
modems and enables the management of traffic equipment over the network.
