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 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.
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 RJ45 serial connectors only 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 Set Ready 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 termination 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 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. 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.
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 32. Figure 3-9.
Chapter 3: Installation and Hardware Table 3-6.
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 Netmask: Number of Bits for Host Part 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 Key Type Encryption Key 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 Enter key prompts for the new passphrase or hexadecimal key. Key Type Encryption Key Hex Enter the Encryption Key as a hexadecimal value according the following guidelines: Passphrase Valid Hex alphanumeric characters are 0-9 and A-F. 64 bit hex = 5 bytes represented as xx-xx-xx-xx-xx. Example: 01-A3-47-E5-C9 128 bit hex = 13 bytes represented as xx-xx-xx-xx-xx-xx-xxxx-xx-xx-xx-xx-xx. Example: A1-B2-C3-E4-D5-F6-98-74-B7-65-A8-D3-F2 Enter the key as a string.
Chapter 4: XPress DR+W Transmission Data Rate If the above TX Data rate is set to fixed, the selected data rate is the XPress DR+W’s fixed transmission rate. If the above TX Data rate is set to auto, the selected data rate is the XPress DR+W’s maximum data rate. Lower data rates allow for larger distances. They may also be required when communicating with older devices. The default setting is 11 Mbps. TX Data rate 0=1, 1=2, 2=5.

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.
Chapter 9: Setup Mode: Channel Configuration If a partial IP address is presented in a command string, it is interpreted to be the least significant bytes of the IP address and uses the internally stored remote IP address to provide the most significant bytes of the IP address. If the IP address entered is 0.0.0.0/0, the device server enters Monitor Mode. 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.
Chapter 9: Setup Mode: Channel Configuration Figure 9-3. Hostlist Option 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 Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with XPress DR+ units, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.
Chapter 9: Setup Mode: Channel Configuration The unit ignores any character sequence received not starting with AT, and only recognizes and processes single AT-style commands. The unit treats compound AT commands as unrecognized commands. If the Full Verbose option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly (begins with AT and ends with carriage return) with the "OK" message and takes no further action.
Chapter 9: Setup Mode: Channel Configuration Modem Mode Command Function Enables or disables connections from the network going to the serial port. n=0 disables the ability to make a connection from the network to the serial port. ATS0=n n=1-9 enables the ability to make a connection from the network to the serial port. n>1-9 is invalid. Enables or disables character echo and responses. n=0 disables character echo and responses. ATEn n=1 enables character echo and responses.
Chapter 9: Setup Mode: Channel Configuration Remote Port You must set the remote TCP port number for the unit to make outgoing connections. This parameter defines the port number on the target host to which a connection is attempted. Remote Port ( 0) ? _ To connect an ASCII terminal to a host using the unit for login purposes, use the remote port number 23 (Internet standard port number for Telnet services).
Chapter 9: Setup Mode: Channel Configuration Flush Mode (Buffer Flushing) Using this parameter, you can control line handling and network buffers with connection startup and disconnect.

Chapter 9: Setup Mode: Channel Configuration Send Characters Enter up to two characters in hexadecimal representation in sendchar. SendChar 1 ( 0) ? _ SendChar 2 ( 0) ? _ If the unit receives a character on the serial line that matches one of these characters, it sends the character immediately, along with any awaiting characters, to the TCP connection. This action minimizes the response time for specific protocol characters on the serial line (for example, ETX, EOT).
Chapter 9: Setup Mode: Channel Configuration US=United States CA=Canada FR=France SP=Spain JP=Japan OT=Others, such as Europe (excluding France), Asia, Africa, and Australia Without adequate protection, a wireless LAN is susceptible to access by unauthorized users. As such, XPress DR+W features the WPA security standard, WPA2 based on IEEE 802.11i. WEP is provided for backwards compatibility and interaction with older devices. To modify WLAN settings, select 4 WLAN from the Change Setup menu.
Chapter 9: Setup Mode: Channel Configuration 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 9: Setup Mode: Channel Configuration Key Type Encryption Key A passphrase of more than 20 characters is recommended. Maximum length is 63 characters, including spaces and punctuation characters. 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) bytes and limits the number of key combinations.

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.
Chapter 13: Troubleshooting and Technical Support 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.
Chapter 13: Troubleshooting and Technical Support 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.
