22:: IInnttrroodduuccttiioonn

The SDS1101 is a single-port device server and the SDS21 01 is a dual port dev ice
server that provide a quick, simple, and cost-effective wa y to bring the adva ntag e s of
data accessibility and remote management to devices not currently connected to a
network.

Applications

The SDS 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).

The SDS1100/2101 Secure Device Server offers secure data communications using
Rijndael Advanced Encr yption Stan dar ds (A ES) and is certified by the National
Institute of Standard and Technology (NIST) to meet Federal Information Processing
Standards (FIPS) required for data communication on US government and
government contractor’s networks.

 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 SDS encapsulates serial data into
packets and transports them over Ethernet. Using two SDS units, connected by a
network, virtual serial connections can extend across a facility or around the world.

Figure 2-1. Serial Tunneling Example

Device Servers

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.

Note: For step-by-step instructions on configuring the SDS for serial tunneling or for

use with the Com Port Redirector, see SDS Configuration Tutorials on the Lantronix
web site:

www.lantronix.com/support.

SDS1101/2101 User Guide 12

Protocol Support

The SDS 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 devic es witho ut a point-to-point connection.

Additional Features

Modem Emulation: In modem emulation mode, the SDS 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 SDS 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 SDS 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 SDS and ass ign ing IP addr es ses and other configurable
settings:

DeviceInstaller: Configure the IP address and other network settings on the SDS
using a Graphical User Interface (GUI) on a PC attached to a network.
(See Assigning the IP Address: DeviceInstaller )

Web-Manager: Through a web browser, configure the SDS 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).

Product Information Label

00-20-4A-14-01-18 or 00:20:4A:14:01:18

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, identif yin g

SDS1101/2101 User Guide 16

Required Information

Before configuring the SDS, have the following information available:

Hardware Address

Take note of the unit’s hardware address (also known as the Ether net 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 (see Product Information Label).

Hardware Address: 00-20-4a-_____-_____-_____

IP Address

The SDS 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 SDS tries
BOOTP. If the SDS does not receive a response from BOOTP, it reverts to
an AutoIP address.
