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.

7: Setup Mode: Server Configuration

This chapter explains how to configure the network settings.

Note: Current values display in parentheses.

Server Configuration (Option 0)

The unit’s basic network parameters display when you select Server configuration (option 0). The IP Address, Set Gateway IP Address, and Netmask fields display the current values.

Figure 7-1. Server Settings

IP Address : (000) .(000) .(000) .(000) Set Gateway IP Address (N) Netmask: Number of Bits for Host Part (0=default) (0) Change telnet config password (N)

IP Address

If DHCP is not used to assign IP addresses, enter the IP address manually. The IP address must be set to a unique value in the network. Enter each octet and press Enter between each section. The current value displays in parentheses.

If DHCP is used, the third octet of the IP address sets the BootP/DHCP/AutoIP options. The following table shows the bits you can manually configure to force the XPress DR+ to disable AutoIP, DHCP, or BootP. To disable an option, set the appropriate bit.

For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are disabled; only DHCP is enabled. (The value 5 results from adding the binary equivalents of 0 and 2.) This is the most common setting when using DHCP.

Set Gateway IP Address

The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP address of the router connected to the same LAN segment as the unit. The gateway address must be within the local network. The default setting is N (No), meaning the gateway address has not been set. To set the gateway address, type Y and enter the address.

Set Gateway IP Address (N) ? Y Gateway IP addr ( 0) ( 0) ( 0) ( 0)_

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.

Change Telnet Configuration Password

Setting the Telnet configuration password prevents unauthorized access to Setup Mode through a Telnet connection to port 9999 or through web pages. The password must have 4 characters.

Change telnet config password (N) ? _

An enhanced password setting (for Telnet access only) of 16 characters is available under Security Settings (Option 6) on page 64.

Note: You do not need a password to access the Setup Mode window by a serial

connection.

DHCP Name

If a DHCP server has automatically assigned the IP address and network settings, you can discover the unit by using the DeviceInstaller network search feature.

There are three methods for assigning DHCP names to the unit.

XPress DR+ User Guide 48

7: Setup Mode: Server Configuration

 Default DHCP Name: If you do not change the DHCP name, and you are using

an IP of 0.0.0.0, then the DHCP name defaults to CXXXXXX (XXXXXX is the last 6 digits of the MAC address shown on the label on the bottom/side of the unit). For example, if the MAC address is 00-20-4A-12-34-56, then the default DHCP name is C123456.

 Custom DHCP Name: You can create your own DHCP name. If you are using

an IP address of 0.0.0.0, then the last option in Server configuration is Change DHCP device name. This option allows you to change the DHCP name to an alphanumeric name (LTX in our example).

Change DHCP device name (not set) ? (N) Y Enter new DHCP device name : LTX

 Numeric DHCP Name: You can change the DHCP name by specifying the last

octet of the IP address. When you use this method, the DHCP name is LTXYY where YY is what you chose for the last octet of the IP address. If the IP address you specify is 0.0.0.12, then the DHCP name is LTX12. This method only works with 2 digit numbers (01-99).

Accepts any incoming connection when a connection is not already established. Default setting.

A single character is transmitted to the serial port when there is a change in connection state: C = connected, D = disconnected, N = host unreachable.

Single character mode specifies the character response. The IP address of the host connecting to the unit displays when the unit is in verbose mode. This option is overridden when the Active Start Modem Mode or Active Start Host List is in effect. Default setting is Nothing (quiet).

Does not attempt to initiate a connection under any circumstance. Default setting.

Attempts to connect when any character is received from the serial port.

Attempts to connect when the DTR input changes from not asserted to asserted.

Attempts to connect when it receives a specific start character from the serial port. The default start character is carriage return.

Attempts to connect when directed by a command string received from the serial port. The first character of the command string must be a C (ASCII 0x43), and the last character must be either a carriage return (ASCII 0x0D) or a line feed (0x0A). No blanks or space characters may be in the command string. Between the first and last command string characters must be a full or partial destination IP address and may be a destination port number.

The IP address must be in standard decimal-dot notation and may be a partial address, representing the least significant 1, 2, or 3 bytes of the remote IP address. The period is required between each pair of IP address numbers.

If present, the port number must follow the IP address, must be presented as a decimal number in the range 1-65535, and must be preceded by a forward slash (ASCII 0x2F). The slash separates the IP address and the port number. If you omit the port number from a command string, the internally stored remote port number starts a connection.

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. (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.

Autostart (Automatic Connection)

Hostlist

If you enable Autostart, the unit automatically connects to the remote IP address and remote port specified when the firmware starts.

If you enable this option, the device server scrolls through the hostlist until it connects to a device listed in the hostlist table. Once it connects, the unit stops trying to connect to any others. If this connection fails, the unit continues to scroll through the table until it is able to connect to another IP in the hostlist.

Hostlist supports a minimum of 1 and a maximum of 12 entries. Each entry contains the IP address and the port number. The hostlist is disabled for Manual and Modem Modes. The unit does not accept a data connection from a remote device when the hostlist option is enabled.

Figure 8-3. Hostlist Option

XPress DR+ User Guide 55

8: 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. For Retrycounter, enter the number of times the Lantronix unit should try to make a good network connection to a hostlist entry that it has successfully ARPed. The range is 1-15, with the default set to 3.

5. For Retrytimeout, enter the number of seconds the unit should wait before failing an attempted connection. The time is stored as units of milliseconds in the range of 1-65535. The default setting is 250.

d) Datagram Type

Directed UDP

When selecting this option, you are prompted for the Datagram type. Enter 01 for directed or broadcast UDP.

When the UDP option is in effect, the unit never attempts to initiate a TCP connection because it uses UDP datagrams to send and receive data.

e) Modem Mode

In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device. It accepts AT-style modem commands and handles the modem signals correctly.

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.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response), CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response, CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

XPress DR+ User Guide 56

8: Setup Mode: Channel Configuration

Without Echo

Data Echo & Modem Response

Modem Responses Only

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).

Full Verbose: The unit echoes modem commands and responds to a command with a message string shown in the table below.

Numeric Response: The unit echoes modem commands and responds to a command with a numeric response.

Full Verbose: The unit does not echo modem commands and responds to a command with a message string shown in the table below.

Numeric Response: The unit does not echo modem commands and responds to a command with a numeric response.

4 Error

Received commands must begin with the two-character sequence AT and be terminated with a carriage return character.

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.

If the Numeric Response option is in effect, the unit responds to an unrecognized command string that is otherwise formatted correctly with the "0" message and takes no further action.

When an active connection is in effect, the unit transfers data and does not process commands received from the serial interface.

When a connection is terminated or lost, the unit reverts to command mode.

XPress DR+ User Guide 57

8: 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.

 The character string ATH is received, terminated with a carriage return. The unit

responds affirmatively according to the selected echo/response mode and drops the network connection. The serial interface reverts to accepting command strings.

If this sequence is not followed, the unit remains in data transfer mode.

XPress DR+ User Guide 60

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). Adjusting parameters in this mode can economize the network data stream.

Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not need specific functions.

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.

Packing Interval

Packing Interval defines how long the unit should wait before sending accumulated characters. This wait period is between successive network segments containing data. For alternate packing, the default interval is 12 ms.

Trailing Characters

In some applications, CRC, Checksum, or other trailing characters follow the end-ofsequence character; this option helps to adapt frame transmission to the frame boundary.

XPress DR+ User Guide 61

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. If this option is set, the unit sends immediately after recognizing the transmit condition (sendchar or timeout).

Note: A transmission might occur if status information needs to be exchanged or

an acknowledgment needs to be sent.

DisConnTime (Inactivity Timeout)

DisConnTime (0: 0) ?:

To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes, 59 seconds). Default setting is 0.

8: 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). Setting the first sendchar to 00 disables the recognition of the characters. Alternatively, the unit can interpret two characters as a sequence (see Pack Control on page 61).

Telnet Terminal Type

This parameter displays only if you enabled the terminal type option in Disconnect Mode. With this option enabled, you can use the terminal name for the Telnet terminal type. Enter only one name.

With terminal type option enabled, the unit also reacts to the EOR (end of record) and binary options, useful for applications like terminal emulation to IBM hosts.

Channel (Port) Password

This parameter appears only if the channel (port) password option is enabled in Disconnect Mode. With this option enabled, you can set a password on the serial port.

Obtaining Firmware

You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix web site (www.lantronix.com) or by using anonymous FTP (ftp.lantronix.com).

Reloading Firmware

There are several ways to update the unit's internal operational code (*.ROM): using DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update the unit's internal web interface (*.COB) using TFTP or DeviceInstaller.

Here are typical names for those files. Check the Lantronix web site for the latest versions and release notes.

Table 10-1. Firmware Files

ROM File COB

XDRPL_6101.ROM XDRPL _WEBM_1402.COB

Please refer to the DeviceInstaller online Help for information about reloading firmware using DeviceInstaller. The other methods are discussed below.

Using TFTP: Graphical User Interface

To download new firmware from a computer:

1. Use a TFTP client to send a binary file to the unit (*.ROM to upgrade the unit's internal operational code and *.COB to upgrade its internal web interface).

Note: TFTP requires the .ROM (binary) version of the unit's internal

operational code.

2. In the TFTP server field, enter the IP address of the unit being upgraded.

3. Select Upload operation and Binary format.

4. Enter the full path of the firmware file in the Local file name field.

5. In the Remote file name field, enter the current internal operational code (R1) or WEB1 to WEB19 for the internal web interface.

6. Click the Upload Now button to transfer the file to the unit.

XPress DR+ User Guide 68

Figure 10-1. TFTP Window

After the firmware has been loaded and stored, which takes approximately 8 seconds to complete, the unit performs a power reset.

Using TFTP: Command Line Interface

To download new firmware from a computer:

1. Enter the following from a TFTP command line interface:

tftp –i <ip address> put <local filename> <destination file name>

The following examples demonstrate the TFTP command sequence to download the .ROM file and the .COB file:

tftp –i 192.168.1.111 put xdrpl_6100.rom R1 tftp –i 192.168.1.111 put xdrpl_webm_1402.cob WEB4

2. In the Remote file name field, enter the current internal operational code (R1) or WEB1 to WEB19 for the internal web interface.

Recovering the Firmware Using the Serial Port and DeviceInstaller

If for some reason the firmware is damaged, you can recover the firmware file by using DeviceInstaller to download the *.ROM file over the serial port.

To recover firmware:

1. Start DeviceInstaller. If your PC has more than one network adapter, a message displays. Select an adapter and click OK.

2. From the Tools menu, select Advanced/Recover Firmware. The Serial Port Firmware Upgrade window displays.

3. For Port on PC, enter the COM port on the PC that is connected to the serial port of the Lantronix unit.

11: Monitor Mode

Monitor Mode is a command-line interface used for diagnostic purposes.

There are two ways to enter Monitor Mode: locally using the serial port or remotely using the network.

Entering Monitor Mode Using the Serial Port

To enter Monitor Mode locally:

1. Follow the same steps used for setting the serial configuration parameters (seeSerial Port on page 45).

2. Instead of typing three x keys, however:

a) Type zzz (or xx1) to enter Monitor Mode with network connections.

b) Type yyy (or yy1) to enter Monitor Mode without network connections.

A 0> prompt indicates that you have successfully entered Monitor Mode.

Entering Monitor Mode Using the Network Port

To enter Monitor Mode using a Telnet connection:

1. Establish a Telnet session to the configuration port (9999).

2. Type M (upper case). A 0> prompt indicates that you have successfully entered Monitor Mode.

12: 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. Make sure that your unit's IP address is unique.

When troubleshooting the following problems, make sure that the unit is powered up. Confirm that you are using a good network connection.

Problems and Error Messages

Note: For information about diagnostic LEDs, see page 22.

Table 12-1. Problems and Error Messages

Problem/Message Reason Solution

When you issue the ARP –S command in Windows, the "ARP entry addition failed: 5" message displays.

When you attempt to assign an IP address to the unit by the ARP method, the "Press Enter to go into Setup Mode" error "(described below) message displays. Now when you Telnet to the device server, the connection fails.

When you Telnet to port 9999, the "Press Enter to go into Setup Mode" message displays. However, nothing happens when you press Enter, or your connection closes.

Your currently logged-in user does not have the correct rights to use this command on this PC.

When you Telnet to port 1 on the device server, you are only assigning a temporary IP address. When you Telnet into port 9999 and do not press Enter quickly, the device server reboots, causing it to lose the IP address.

You did not press Enter quickly enough. You only have 5 seconds to press Enter before the connection closes.

Have someone from your IT department log you in with sufficient rights.

Telnet back to port 1. Wait for it to fail, then Telnet to port 9999 again. Make sure you press Enter quickly.

Telnet to port 9999 again, but press Enter as soon as you see the "Press Enter to go into Setup Mode" message.

XPress DR+ User Guide 73

12: 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.

When you try to assign an IP with DeviceInstaller, you get the following :

"No response from device! Verify the IP, Hardware Address and Network Class. Please try again."

The device server is not communicating with the serial device to which it is attached.

When you try to enter the setup mode on the device server using the serial port, you get no response.

You may have entered the Ethernet address incorrectly with the ARP command.

The IP address you are trying to assign is not on your logical subnet.

The device server may not be plugged into the network properly.

The cause is most likely one of the following:

The hardware address you specified is incorrect.

The IP address you are trying to assign is not a valid IP for your logical subnet.

You did not choose the correct subnet mask.

The most likely reason is the wrong serial settings were chosen.

The issue is most likely something covered in the previous problem, or possibly, you have Caps Lock on.

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. In Windows and usually in Unix, the segments of the Ethernet address are separated by dashes. In some forms of Unix, the Ethernet address is segmented by colons.

Confirm that your PC has an IP address and that it is in the same logical subnet that you are trying to assign to the device server.

Make sure that the Link LED is lit. If the Link LED is not lit, then the device server is not properly plugged into the network.

Double-check the parameters that you specified.

Note: You cannot assign an IP

address to a device server through a router.

The serial settings for the serial device and the device server must match. The default serial settings for the device server are RS-232, 9600 baud, 8

character bits, no parity, 1 stop bit, no flow control.

Double-check everything in the problem above. Confirm that Caps Lock is not on.

XPress DR+ User Guide 74

12: Troubleshooting and Technical Support

Problem/Message Reason Solution

You can ping the device server, but not Telnet to the device server on port 9999.

The device server appears to be set up correctly, but you are not communicating with your device attached to the device server across the network.

When connecting to the WebManager within the device server, the "No Connection With The Device Server" message displays.

There may be an IP address conflict on your network

You are not Telneting to port 9999.

The Telnet configuration port (9999) is disabled within the device server security settings.

If you are sure that the serial port setting is correct, then you may not be connecting to the correct socket of the device server.

Another possibility is that the device server is not set up correctly to make a good socket connection to the network.

Your computer is not able to connect to port 30718 (77FEh) on the device server.

Turn the device server off and then issue the following commands at the DOS prompt of your computer:

ARP -D X.X.X.X (X.X.X.X is the IP of the device server).

PING X.X.X.X (X.X.X.X is the IP of the device server). If you get a response, then there is a duplicate IP address on the network. If you do not get a response, use the serial port to verify that Telnet is not disabled.

You can check to see whether there is a socket connection to or from the device server by looking at the Status LED.

If the Status LED is blinking consistently, then there is a good socket connection.

If the Status LED is solid green, then the socket connection does not exist. Use the Connect Mode option C0 for making a connection to the device server from the network. Use Connect Mode option C1 or C5 for a connection to the network from the device server.

Make sure that port 30718 (77FEh) is not blocked with any router that you are using on the network. Also, make sure that port 77FEh is not disabled within the Security settings of the device server.

XPress DR+ User Guide 79

C: Alternative Methods of Assigning an IP

Address

Earlier chapters describe how to assign a static IP address using DeviceInstaller, WebManager, and Setup Mode (through a Telnet or serial connection). This section covers other methods for assigning an IP address over the network.

DHCP

The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit boots up.

You can use the DeviceInstaller software (if applicable) to search the network for the DHCP-assigned IP address and add it to the list of devices retrieved.

Note: This DHCP address does not appear in the unit’s Setup Mode or in Web-

Manager. You can determine your unit’s DHCP-assigned IP address in Monitor Mode. When you enter Monitor Mode from the serial port with network connection enabled and issue the NC (Network Communication) command, you see the unit’s IP configuration.

AutoIP

The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address automatically in smaller networks that may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses over the Internet.

 If your unit cannot find a DHCP server, and you have not manually assigned an

IP address to it, the unit automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request to other nodes on the same network to see whether the selected address is being used.

 If the selected address is not in use, the unit uses it for local subnet

communication.

 If another device is using the selected IP address, the unit selects another

address from the AutoIP range and reboots. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so on.

AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it finds a DHCP server, the unit switches to the DHCP server-provided address and reboots.

XPress DR+ User Guide 80

C: Alternative Methods of Assigning an IP Address

Note: If a DHCP server is found, but it denies the request for an IP address, the

unit does not attach to the network, but waits and retries.

You can disable AutoIP by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but disables AutoIP.

BOOTP

Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific duration of time.

ARP and Telnet

If the unit has no IP address, you can use Address Resolution Protocol (ARP).

To assign a temporary IP address:

1. On a UNIX or Windows-based host, create an entry in the host's ARP table using the intended IP address and the hardware address of the unit (on the product label on the bottom of the unit).

arp -s 191.12.3.77 00:20:4a:xx:xx:xx

Note: For the ARP command to work on Windows 95, the ARP table on

the PC must have at least one IP address defined other than its own.

2. If you are using Windows 95, type ARP -A at the DOS command prompt to verify that there is at least one entry in the ARP table. If the local machine is the only entry, ping another IP address on your network to build a new entry in the ARP table; the IP address must be a host other than the machine on which you are working. Once there is at least one additional entry in the ARP table, use the following command to ARP an IP address to the unit:

arp -s 191.12.3.77 00-20-4a-xx-xx-xx

3. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily changes its IP address to the one designated in this step.

telnet 191.12.3.77 1

4. Open a Telnet connection to port 9999, and press Enter within five seconds to go into Setup Mode. If you wait longer than five seconds, the unit reboots.

telnet 191.12.3.77 9999

Note: The IP address you just set is temporary and reverts to the default value

when the unit’s power is reset, unless you configure the unit with a static IP address and store the changes permanently.

XPress DR+ User Guide 81

D: Binary to Hexadecimal Conversions

Many of the unit’s configuration procedures require you to assemble a series of options (represented as bits) into a complete command (represented as a byte). The resulting binary value must be converted to a hexadecimal representation.

Converting Binary to Hexadecimal

Following are two simple ways to convert binary numbers to hexadecimal notation.

Conversion Table

Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A (for

10), B (for 11), etc. To convert a binary value (for example, 0100 1100) to a hexadecimal representation, treat the upper and lower four bits separately to produce a two-digit hexadecimal number (in this case, 4C). Use the following table to convert values from binary to hexadecimal.

Decimal Binary Hex Decimal Binary Hex

0 0000 0 8 1000 8

1 0001 1 9 1001 9

2 0010 2 10 1010 A

3 0011 3 12 1100 C

4 0100 4 13 1101 D

5 0101 5 14 1110 E

6 0110 6 15 1111 F

7 0111 7

Scientific Calculator

Another simple way to convert binary to hexadecimals is to use a scientific calculator, such as the one available on Windows’ operating systems. For example:

1. On the Windows’ Start menu, click ProgramsÆAccessoriesÆCalculator.

1. On the View menu, select Scientific. The scientific calculator displays.

2. Click Bin (Binary), and type the number you want to convert.
