XPress DR+ User Guide 10

2: Introduction

This chapter provides basic information about the XPress DR+.

Product Description

The Lantronix XPress DR+ Industrial Device Server is a robust, feature-rich, and cost
effective way to network-enable equipment in an industrial automation environment. The
XPress DR+ provides two serial ports, two switched Ethernet ports, a wide power input
range, and expanded environmental specifications, making it an ideal solution
for connecting multiple asynchronous RS232, RS422, or RS485 serial devices to an
Ethernet network.

The internal two-port Ethernet switch allows the XPress DR+ to cascade connections
from a single network drop to another Ethernet device or from one XPress DR+ to
another and another, and so on. By leveraging a single network drop to connect multiple
devices, the XPress DR+ greatly reduces device connectivity costs, reduces cabling cost
and simplifies system changes and device moves.

By encapsulating serial data and transporting it over Ethernet, the XPress DR+ allows
virtual serial links over Ethernet and IP (TCP/IP, UDP/IP) networks. As a result, you can
extend limited distance, point-to-point, direct serial connections within the plant,
throughout the facility, or across the global enterprise.

The XPress DR+ provides an impressive list of features and functions enabling multiple
industrial automation devices to be connected, controlled, configured, managed, and
updated over a network. With two serial ports and two auto-sensing Ethernet ports, the
XPress DR+ can easily connect multiple serial devices to a network and cascade from
one XPress DR+ to another from a single network drop.

Types of supported devices:

 Programmable controllers (PLCs)
 Process controllers
 Motor drive controllers
 Power monitoring equipment
 Human-machine interfaces
 Robots
 Flow meters
 Temperature monitoring equipment
 Scales
 Mixing stations
 Gas detection devices
 CNC Machines

XPress DR+ User Guide 11

2: Introduction

The XPress DR+ can connect devices using various methods of TCP/IP communications,
for example, through a TCP data channel, using UDP datagrams, or though a Telnet
connection. Communication can be established from the XPress DR+ to a host computer
or another device or from a host computer or device to the XPress DR+.

Figure 2-1. XPress DR+ (Front)

The XPress-DR+ supports RS-232 through RJ45 connectors. It also supports
RS-422/485 by means of screw terminals (Serial Port 2 only). It has two Ethernet Ports
10/100Base-T and –TX with Auto MDI/MDI-X by means of RJ45 connectors. You can use
either Ethernet port for daisy-chained configuration.

Industrial Automation Protocols

The XPress DR+, 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.

The XPress DR+ is delivered with IAP Standard Tunneling protocol and can be loaded
with industrial communication protocols. The suite of protocols includes DF1 Multi-Master
(Rockwell Automation) and Modbus Bridge, which supports MODBUS/TCP,
MODBUS/ASCII, and MODBUS/RTU (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.

XPress DR+ User Guide 12

For information about using any of the industrial communication protocols, see the
specific protocol guides on the software CD or the Lantronix web site. Protocol firmware
files are also on the CD.

Note: Please check the Lantronix web site for newer versions that may become

available.

You can set up the unit using the serial port or remotely over Ethernet using Telnet or,
when using the Standard Tunneling firmware, 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. The XPress DR+ uses Flash memory for maintenance-free, non-volatile storage
that allows fast system upgrades.

Network Protocols (Serial Tunneling)

The XPress DR+ uses TCP/IP protocols for network communication. The supported
standards are ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, AutoIP, MODBUS/TCP, and
SNMP. For transparent connections, TCP/IP (binary stream) or Telnet protocols are
used. You can perform firmware upgrades 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.

2: Introduction

For typical datagram applications, where devices interact with others without maintaining
a point-to-point connection, UDP datagram is supported in the Standard Tunnel Protocol.

XPress DR+ comes loaded with Standard Tunnel Protocol. Standard Tunneling is a serial
communications protocol used by most Lantronix device servers. You can configure it to
Ethernet-enable most serial devices such as barcode scanners, weigh scales, operator
panels, data access devices, alphanumeric displays, and thousands of intelligent serial
devices.

Loading industrial protocols such as Modbus to an XPress DR+ changes the
configuration dialogs. See the user guides on individual protocols for protocol-specific
settings and configuration dialogs. Protocol manuals are on the software CD.

Note: This User Guide describes the setup and configuration dialogs for the

Standard Tunnel Protocol.

Application Examples

Using a method called serial tunneling, the XPress DR+ encapsulates serial data into
packets and transports them over Ethernet. Using two XPress DR+ units, connected by a
network, you can extend virtual serial connections across a facility or around the world.

XPress DR+ User Guide 13

2: Introduction

Figure 2-2. Example of Serial Tunneling

The internal two-port Ethernet switch allows the XPress DR+ to cascade connections
from a single network drop to another Ethernet device or from one XPress DR+ to
another and another, and so on.

XPress DR+ User Guide 14

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address or 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.

Figure 2-4. Sample Hardware Address

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

IP Address

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

Port Numbers

2: Introduction

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 phone system.

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

Configuration Methods

After installation, the XPress DR+ requires configuration for the unit to operate correctly
on a network. There are three basic methods for logging into the XPress DR+ and editing
the configurable settings.

DeviceInstaller: Configures the IP address and other network settings on the XPress
DR+ using a Graphical User Interface (GUI) on a PC attached to a network.
(See 4: Using DeviceInstaller.)

Web-Manager: Through a web interface, configures the XPress DR+ settings using the
Lantronix Web-Manager. (See 5: Configuration Using Web-Manager.)

Serial and Telnet Ports: 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 6: Configuration Using Telnet or Serial Port (Setup Mode) through 9: Setup Mode:

Advanced Settings.)

Ethernet Interface

The XPress DR+ includes a two-port unmanaged Ethernet switch with a future option to
migrate to a managed solution.

The internal IEEE 802.3-compliant Ethernet switch is non-blocking, using a 1K MAC
address lookup table with store-and-forward architecture. The XPress DR+ supports
auto-negotiation for 10Base-T or 100Base-TX in both full and half-duplex modes, as well
as automatic MDI/MDIX crossover, allowing use of both straight-through or crossed
Ethernet cables. The unit also supports IEEE 802.1d spanning tree, which protects
against the possibility of a network loop.

Multi-Drop Ethernet Connections

Although there are two Ethernet ports, the XPress DR+ only has one MAC address and
IP address. Either port can be used as the primary connection with the other used
to inter-connect other Ethernet devices or cascade from one XPress DR+ to another.

Power Requirements

As with most industrial automation devices, the XPress DR+ does not ship with a power
supply. Its flexible power input circuit allows the product to be powered by any 9-30 VDC
or 9-24 VAC power supply that can provide the 2.3-Watt maximum required by the
XPress DR+.

In addition to the wide power input range, the XPress DR+ provides:

 2K VAC and 2.8K VDC galvanic isolation between the power input and the

 2K VAC and 2.8K VDC galvanic isolation between the power input and the serial

Ethernet ports

ports

Reset Switch

The XPress DR+ includes a hardware reset switch located in the small hole above the
power connector. Pressing the reset switch provides a hardware reboot of the XPress
DR+. The hardware reset does not reset or change the configuration of the XPress DR+.
(See Figure 3-2. Front Panel Layout).

you manually assign the IP address over the network using DeviceInstaller software,
which is on the product CD.

Note: To use a serial connection instead of an Ethernet connection to configure the

device, see Configuration Using Telnet or Serial Port (Setup Mode) on page 45.
