    This user guide describes and provides the information needed to configure, use, and update the Lantronix® XPress™ DR+ industrial device server. These device servers are members of the XPress family that work with Industrial Automation Protocols (IAP). It is for system administrators and those responsible for installing and maintaining these device servers.

Live tutorials on the Explain and demonstrate assigning an IP address and setting up the unit and the Redirector.

  • Page 11: 2: Introduction

    2: Introduction 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 RS-232, RS-422, or RS-485 serial devices to an Ethernet network.

  • Page 12: Industrial Automation Protocols

    For information about using any of the industrial communication protocols, find the protocol firmware files and the specific protocol guides at the Lantronix website at www.lantronix.com/support/downloads.html. XPress™ DR+ Industrial Device Server User Guide...

  • Page 13: Network Protocols (Serial Tunneling)

    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.

  • Page 14: Xpress Dr+ Application Examples

    2: Introduction XPress DR+ 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. Figure 2-2.

  • Page 15: Addresses And Port Numbers

    2: Introduction Figure 2-3. Example of Cascading Multiple XPress DR+ Units Addresses and Port Numbers Hardware Address The hardware address is also referred to as the Ethernet address or MAC address. Take note of the unit’s hardware address (also known as the Ethernet or MAC address). It is on the product label (see Product Information Label).

  • Page 16: Configuration Methods

    2: Introduction 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. You can associate the unit's serial channel (port) with a specific TCP/UDP port number.

  • Page 17: 3: Installation And Hardware

    The following diagram shows the basic connectivity of an XPress DR+ to the network and a serial device. The Lantronix-supplied part number 500-103-R serial cable can be used on the RJ45 RS- 232 serial ports to connect the XPress DR+ to a PC or to a serial device that has a DB9M RS-232 DTE interface.
