Chapter 1: Using This Guide Purpose and Audience This manual describes the Lantronix XPress DR+ and XPress DR+W device servers. These device servers are members of the XPress family that work with Industrial Automation Protocols. The XPress DR+ W has wireless as well as wired capability. This guide provides the information needed to configure, use, and update the XPress DR+ device servers. It is for system administrators and those responsible for installing and maintaining these device servers.
Chapter 1: Using This Guide Chapter 13: Troubleshooting and Technical Support Describes common problems and error messages and how to contact Lantronix Technical Support. Appendix A: Technical Specifications Lists technical information about the unit. Appendix C: Alternative Methods of Assigning an IP Address Describes other ways to assign an IP address, for example, though ARP and Telnet.
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.
Chapter 2: Introduction 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.
Chapter 2: Introduction 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.
Chapter 2: Introduction 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.
Chapter 2: Introduction Figure 2-3. Example of Cascading Multiple XPress DR+ Units Note: For examples of wireless applications, see Chapter 4: XPress DR+W. 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.
Chapter 2: Introduction 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.
Chapter 3: Installation and Hardware What's in the Box? Verify and inspect the contents of the package using the enclosed packing slip or the list below. If any item is missing or damaged, contact your place of purchase immediately. XPress DR+ or XPress DR+W Resource CD Quick Start Guide P/N: 500-103 RJ45-DB9F serial cable.
Chapter 3: Installation and Hardware Figure 3-1. Typical Configuration 1. Connect a serial device to your XPress DR+. (See Serial Interface on page 20 for cable and connector specifications.) 2. Connect an Ethernet cable to the Ethernet port. (See Ethernet Interface on page 23.) 3. Supply power to your XPress DR+ using a 9-30 VDC or 9-24 VAC (2.3W maximum) source. (See Power Requirements on page 24.) 4. Supply power to the serial device.
Chapter 3: Installation and Hardware Figure 3-2. Front of XPress DR+ 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 serial RJ45 serial connectors support RS232, up to 230400 bits per second.
Chapter 3: Installation and Hardware Figure 3-3. RJ45 Connector – Front View Table 3-1. RJ45 Serial Connector Pinouts Pin Direction Name Function 1 Output from DR+ RTS Ready To Send 2 Output from DR+ DTR Data Terminal Ready 3 Output from DR+ TXD Transmitted Data 4 Ground GND Signal Ground 5 Ground GND Signal Ground 6 Input to DR+ RXD Received Data 7 Input to DR+ DSR Data Carrier Detected 8 Input to DR+ CTS Clear To Send Screw Terminal Serial Connectors Table 3-2.
Chapter 3: Installation and Hardware 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 terminator resistors may not be needed for your application. Figure 3-5.
Chapter 3: Installation and Hardware 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.
Chapter 3: Installation and Hardware Figure 3-7. Multi-Drop Ethernet Connections 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.
Chapter 3: Installation and Hardware Figure 3-8. Reset Switch Caution: Even though a chassis ground is not required for operation, it is mandatory for protection against transient voltages and ESD. A chassis ground must be connected to earth. LEDs Note: For a description of the XPress DR+W's LEDs, see page 33. Figure 3-9.

Steady On Ethernet link established.
Chapter 3: Installation and Hardware Wall Mount Bracket Included with the XPress DR+ is an accessory DIN-rail wall mount bracket that makes it very easy to mount the unit in locations where a DIN-rail is not available. Figure 3-11.
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.
Chapter 4: 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.
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.

Chapter 4: XPress DR+W IP Address: _______ Subnet Mask: Gateway: _______ _______ _______ _______ _______ _______ _______ _______ _______ _______ _______ WLAN Settings Before the XPress DR+W can communicate on an 802.11b/g wireless network, the WLAN settings must match the wireless network. By default, the XPress DR+W is set to Ad Hoc network mode, and its wireless Network Name (SSID) is LTRX_IBSS. You can configure WEP, WPA, or WPA2/802.11i settings: Note: WPA and WPA2/802.
Chapter 4: XPress DR+W Network Mode (XPress DR+W only) The first prompt requires you to set the unit for wired or wireless use. Wireless is the default, so just press Enter at the prompt. Figure 4-7. Network Mode The IP Address, Set Gateway IP Address, and Netmask fields display the current values. Figure 4-8. Server Settings IP Address : (000) .(000) .(000) .
Chapter 4: XPress DR+W A netmask defines the number of bits taken from the IP address that are assigned for the host part. Netmask: Number of Bits for Host Part (0=default) (0) _ Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits The unit prompts for the number of host bits to be entered, then calculates the netmask, which appears in standard decimal-dot notation (for example, 255.255.255.0) when the saved parameters display. Table 4-3.
Chapter 4: XPress DR+W Leaving the zone blank causes the utility to report the current setting only. Following are valid zone abbreviations. These settings are consistent with IEEE802.11b/g zones: US=United States CA=Canada FR=France SP=Spain JP=Japan OT=Others, such as Europe (excluding France), Asia, Africa, and Australia To modify WLAN settings, select 4 WLAN from the Change Setup menu. Topology Select Infrastructure (ESS) mode or Adhoc (IBSS) mode. Infrastructure mode communicates with Access Points.
Chapter 4: XPress DR+W Point to many wireless devices at once is called multicast and uses the group encryption method. To receive broadcast and multicast messages, the group encryption for all wireless devices communicating with the same access point must be equal. If any of these devices is WEP-only (no support for WPA), set the encryption to TKIP+WEP.
Chapter 4: XPress DR+W Passphrase input is not the same as ASCII input. The passphrase input is safer because it has up to 63 characters. ASCII input has a maximum of 5 (WEP64) or 13 (WEP128) characters and limits the number of key combinations. TX Key index selects the WEP key used for transmissions. Enter a value between 1 and 4. The default setting is 1. In case the WEP key is entered in hex, all keys (1-4) are the same.
Chapter 4: XPress DR+W input style recommended. Set the Encryption type to the minimum required security. The plus sign denotes that the group (broadcast) encryption method is different from the pairwise (unicast) encryption, in this case WEP and TKIP, respectively. For example, CCMP+TKIP => pairwise = CCMP, and group = TKIP. WPA2/802.11i The WPA2/802.11i mode complies with the Robust Secure Network specified in the IEEE standard 802.11i. It enables the AES-based strong CCMP encryption.

Chapter 9: Setup Mode: Channel Configuration Note: All bit positions in the table that are blank represent “don’t care” bits, for that particular option, which can be set to either a 0 or 1 value. Table 9-5.
Chapter 9: Setup Mode: Channel Configuration a) Incoming Connection Never Accept Incoming Rejects all external connection attempts. Accept with DTR Active Accepts external connection requests only when the DTR input is asserted. Cannot be used with Modem Mode. Always Accept Accepts any incoming connection when a connection is not already established. Default setting.
Chapter 9: Setup Mode: Channel Configuration For example, if the remote IP address already configured in the unit is 129.1.2.3, then an example command string would be C3/7. (This would connect to 129.1.2.3 and port 7.) You may also use a different ending for the connection string. For example, C50.1/23 would connect you to 129.1.50.1 and port 23. Figure 9-2. Manual Connection Address Example Command String Result if remote IP is 129.1.2.3 and remote port is 1234 C121.2.4.
Chapter 9: Setup Mode: Channel Configuration To enable the hostlist: 1. Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you a list of current entries already defined in the product. 2. To delete, modify, or add an entry, select Yes. If you enter an IP address of 0.0.0.0, that entry and all others after it are deleted. 3. After completing the hostlist, repeat the previous step if necessary to edit the hostlist again. 4.
Chapter 9: Setup Mode: Channel Configuration Without Echo In Modem Mode, echo refers to the echo of all of the characters entered in command mode; it does not mean to echo data that is transferred. Quiet Mode (without echo) refers to the modem not sending an answer to the commands received (or displaying what was typed). Data Echo & Modem Response Full Verbose: The unit echoes modem commands and responds to a command with a message string shown in the table below.
Chapter 9: Setup Mode: Channel Configuration When an active connection is in effect, the unit terminates the connection if it receives the following sequence from the attached serial device: No serial data is received for one second. The character sequence +++ is received, with no more than one second between each two characters. No serial data is received for one second after the last + character. At this time, the unit responds affirmatively per the selected echo/response mode.
Chapter 9: Setup Mode: Channel Configuration Send the Escape Sequence (+++) in Modem Mode Send ‘+++’ in Modem Mode (Y) ? _ Disable or enable the unit's ability to send the escape sequence. The default is Y (Yes) (send the escape sequence). Auto Increment Source Port Auto increment source port (N) ? _ Y (Yes) auto increments the source port. The XPress DR+ increments the port number used with each new connection. Remote IP Address This is the destination IP address used with an outgoing connection.

Chapter 9: Setup Mode: Channel Configuration Pack Control The packing algorithms define how and when packets are sent to the network. The standard algorithm is optimized for applications in which the unit is used in a local environment, allowing for very small delays for single characters, while keeping the packet count low. The alternate packing algorithm minimizes the packet count on the network and is especially useful in applications in a routed Wide Area Network (WAN).
Chapter 9: Setup Mode: Channel Configuration Send Characters If 2-Byte Send Character Sequence is enabled, the unit interprets the sendchars as a 2-byte sequence; if this option is not enabled, the unit interprets them independently. If Send Immediately After Characters is not set, any characters already in the serial buffer are included in the transmission after a "transmit" condition is found.
Chapter 9: Setup Mode: Channel Configuration WLAN Settings (XPress DR+W Only) Note: To use DeviceInstaller for communication to an XPress DR+W over a wireless network, you must first configure the network and WLAN settings using a serial connection. See Chapter 4:XPress DR+W. Before the XPress DR+W can communicate on an 802.11b/g wireless network, the WLAN settings must match the wireless network. By default, the XPress DR+W is set to Ad Hoc network mode, and its wireless Network Name (SSID) is LTRX_IBSS.
Chapter 9: Setup Mode: Channel Configuration Adhoc Network Channel When Adhoc is selected in the Topology parameter, and the XPress DR+W cannot find the specified network, it creates one with that name by transmitting a beacon on the selected channel. Channel (11) ? _ Only channels allowed in the country for which the XPress DR+W is designated can be selected. The country displays in the Setup Mode settings overview.

Chapter 13: Troubleshooting and Technical Support This chapter discusses how you can diagnose and fix errors quickly without having to contact a dealer or Lantronix. It helps to connect a terminal to the serial port while diagnosing an error to view summary messages that may display. When troubleshooting, always ensure that the physical connections (power cable, network cable, and serial cable) are secure. Note: Some unexplained errors might be caused by duplicate IP addresses on the network.
Appendix A:Technical Specifications Problem/Message Reason Solution When you Telnet to port 1 to assign an IP address to the device server, the Telnet window does not respond for a long time. You may have entered the Ethernet address incorrectly with the ARP command. Confirm that the Ethernet address that you entered with the ARP command is correct. The Ethernet address may only include numbers 0-9 and letters A-F.
Appendix A:Technical Specifications Problem/Message Reason Solution You can ping the device server, but not Telnet to the device server on port 9999. There may be an IP address conflict on your network Turn the device server off and then issue the following commands at the DOS prompt of your computer: You are not Telneting to port 9999. The Telnet configuration port (9999) is disabled within the device server security settings.
