XPress DR+ User Guide 11
Chapter 2: Introduction
This chapter provides basic information about the wired and wireless versions of the XPress DR+. The wireless version has two modes of operation: wireless and wired. In wired mode, the wireless functionality is not used, and the unit behaves identically to the wired XPress DR+. In wireless mode, the unit's behavior is wireless to serial, and the Ethernet ports are not functional.
Unless otherwise noted, information in this User Guide applies to both versions of the product. Information specific to the wireless version of the XPress DR+ unit is in
Chapter 4: XPress DR+W.
Note: In this User Guide we sometimes refer to the XPress DR+W as "the wireless unit"
or the "wireless device server."

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 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
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)
Note: For a diagram and description of XPress DR+W, see Front Panel
Description on page 31.
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.
XPress DR+ User Guide 13

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 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 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 serial port 1 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.
Chapter 2: Introduction

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.
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.
XPress DR+ User Guide 14
Loading industrial protocols such as Modbus Bridge 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.

XPress DR+ Application Examples

Note: For XPress DR+W application examples, see Chapter 4: XPress DR+W.
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.
Figure 2-2. Example of Serial Tunneling
Chapter 2: Introduction
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.

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
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.
XPress DR+ User Guide 16
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 Chapter 5: Using DeviceInstaller.)
Web Manager: Through a web interface, configures the XPress DR+ settings using the Lantronix Web Manager. (See Chapter 6: 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. To use DeviceInstaller for communication to an XPress DR+W over a wireless network, the WLAN network settings must be configured first.

Serial Interface

The XPress DR+ supports RS-232 via RJ45 connectors. It also supports RS-422/485 via screw terminals (Serial Port 2 only).
Note: Serial Port 2 supports RS232, RS422, and RS485, but only one mode at a
time. This means you can use either the RJ45 connector or the terminal block, not both.
The RJ45 serial connectors only support RS232, up to 230400 bits per second.

Note: Termination resistors (R = 120 Ohm) are used to match impedance of a
node to the impedance of the transmission (TX) line. Termination resistors should be placed only at the extreme ends of the data line, and no more than two terminations should be placed in any single segment of an RS-485 network. The termination resistors may not be needed for your application.

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 full and half-duplex modes, as well as automatic MDI/MDIX crossover, allowing use of both straight-through and crossed Ethernet cables. The unit also supports IEEE 802.1d spanning tree, which protects against the possibility of a network loop.

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 causes a hardware reboot of the XPress DR+. The hardware reset does not reset or change the configuration of the XPress DR+.

Chapter 4: XPress DR+W
The wireless version of the XPress DR+ (XPress DR+W) provides serial-to-wireless network connectivity as an alternative to wired Ethernet connectivity. The wireless unit uses IP protocol (TCP for connection-oriented stream applications and UDP for datagram applications), enabling virtually any serial device or equipment to be remotely accessed, controlled, monitored, or shared on an 802.11b/g wireless network. The XPress DR+W provides a fully integrated solution that combines an operating system, embedded Web server, full TCP/IP protocol stack with an 802.11b/g transceiver supporting WEP and WPA security.

Application Examples

The XPress DR+W has an 802.11b/g transceiver in addition to its serial and Ethernet ports. Each serial port is connected to the serial communication port of a device. The wireless transceiver connects to another wireless device or to an Access Point (AP). This section includes typical scenarios for using the XPress DR+W.

connected to it. The combination of the XPress DR+W, a PC, and Lantronix’s Com Port Redirector software allows the PC to communicate directly to the wireless unit’s serial devices, providing wireless serial tunneling. Com Port Redirector is available on the product CD and the Lantronix web site (www.lantronix.com
).
Ad Hoc Network
Figure 4-2. Ad Hoc Network Example
In the example above, the AP is not present. The PC makes a direct wireless connection with the XPress DR+W to manage serial devices. Without an AP, it is a peer-to-peer relationship.

Chapter 4: XPress DR+W
In the example above, the XPress DR+W communicates with another device server via the AP. The UDS device server, in this example, is connected via an Ethernet connection to the AP. In this way, the XPress DR+W and the device server communicate directly and can transfer information between their serial devices.
Ad Hoc XPress DR+W Connection
Figure 4-4. Direct XPress DR+W - to- XPress DR+W Connection
In the example above, two XPress DR+W s have established an Ad Hoc peer-to-peer relationship. They communicate directly to each other’s serial devices without a PC or an AP.
