2: Introduction

PLCs XPress DR-IAP

XPress DR-IAP Industrial Device Server

Note: This section is for the XPress DR-IAP only.

The Lantronix Industrial Automation Platform (IAP) family of device servers allows a single
network and protocol to connect multiple serial devices from many vendors. IAP provides the
automation industry with a network-enabling solution using TCP/IP and standard Ethernet
networks that is vendor-independent.

By encapsulating serial data and transporting it over Ethernet, the device server allows virtual
serial links to be established over Ethernet and IP (TCP/IP, UDP/IP) networks. As a result, limited
distance, point-to-point, direct serial connections can be extended within the plant, throughout the
facility, or across the global enterprise. The following picture is one of the device servers in the
IAP family.

Figure 2-1 RS-485 Multidrop with XPress DR-IAP

Lantronix provides IAP device servers are specifically designed for different industrial
environments.

 XPress DR-IAP, with DIN rail interface for harsh environments or alongside control

instruments in electrical panels

 UDS1100-IAP, a rugged device server for use in applications that require a wide operating

temperature range (-40 to 70°C)

 xDirect-IAP, a compact device server with multiple power options including PoE and wide

operating temperature range (-40 to 85°C)

A few examples of attached devices are:

 PLCs
 AC/DC drives
 CNC systems
 Operator panels and message displays
 Process Controls
 Instrumentation
 Power monitoring equipment
 Scales and weighing systems

Protocol Support

Industrial Automation Protocols

IAP device servers, 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.

IAP device servers are delivered with IAP Standard Tunneling protocol and can be loaded with
industrial communication protocols. 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.

For information about using any of the industrial communication protocols, see user manuals and
protocol firmware files available at www.lantronix.com/downloads

2: Introduction

.

You can set up the unit using the serial port, or remotely over Ethernet using Telnet or a web
browser. The Lantronix® DeviceInstaller™ application, a Windows
that simplifies the process of installing protocols and configuring them for use with attached
devices. The DeviceInstaller application is also available for download at

www.lantronix.com/downloads

free, non-volatile storage which allows for fast system upgrades.

Network Protocols (Standard Tunneling)

The XPress DR uses TCP/IP protocols for network communication. The supported standards are:
ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, AutoIP, and SNMP. For transparent connections,
TCP/IP (binary stream) or Telnet protocols are used. Firmware upgrades can be made 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 point­to-point connection, UDP datagram is used.

Additional Features

Packing Algorithm

The two available packet algorithms (which define how and when packets are sent to the
network) are software selectable. The standard algorithm is optimized for applications where
XPress DR is used in a local environment, allowing for very small delays for single characters
while trying to keep the packet count low. The alternate packing algorithm minimizes the packet
count on the network and is especially useful for applications in routed Wide Area Networks.
Various parameters can be set in this mode to economize the serial data stream.

based configuration software

. XPress DR device servers use flash memory for maintenance-

IP Address

Every active device connected to the TCP/IP network must have a unique IP address. This IP
address is used to reference a specific device, for example, to build a connection to XPress DR’s
serial port. See E: Alternative Ways to Assign an IP Address for a complete description of IP
Addressing.

Port Number

A destination IP address and a port number define every TCP connection and every UDP
datagram. A port number is necessary to address an application or a channel on a network host.
The port number can be compared to an extension on a PBX system.

A Telnet application (login to a host with an ASCII terminal) is commonly assigned TCP port
number 23. More than one Telnet connection can be established to one host using the Telnet
port; however, the other peer IP address/port number combinations must be different.

In the XPress DR, a port number can be configured on the channel (port). The XPress DR uses
this port number for outgoing messages and incoming connections, or UDP datagrams, which are
addressed to its port number. Port 9999 (decimal) is used for remote configuration.

Configuration Methods

After installation, the XPress DR requires configuration. For the unit to operate correctly on a
network, it must have a unique IP address on the network. There are three basic methods for
logging into the XPress DR and assigning IP addresses and other configurable settings:

DeviceInstaller: Configure 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 browser, configure the XPress DR settings using the Lantronix
Web-Manager. See 5: Configuration Using Web Manager.

2: Introduction

Dimensions

Serial and Telnet Ports: Use Setup Mode, a command line interface. 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 via Telnet or Serial Port (Setup Mode).

The XPress DR dimensions are shown in the following drawing.

3: Installation of the XPress DR Device Server

This section describes how to install your XPress DR device server and get it up and running in
the shortest possible time.

XPress DR comes with standard tunnel protocol and the XPress DR-IAP comes with the IAP
standard tunnel protocol. Both versions are similar but cannot be interchanged. Standard
tunneling is a serial communications protocol used by most Lantronix device servers. It can be
configured to Ethernet-enable most serial devices such as barcode scanners, weigh scales,
operator panels, data access devices, alpha numeric displays, and thousands of intelligent serial
devices. For XPress DR-IAP users, see Industrial Automation Protocols.

Loading industrial protocols to an XPress DR-IAP, such as IAP Modbus Bridge, may remove the
web pages and change the configure dialogs. See the user manuals on individual protocols for
protocol specific settings and configuration dialogs. Protocol manuals are found at

www.lantronix.com/downloads

Note: The following information is based on the condition that a XPress DR is loaded with

Standard Tunnel Protocol. The XPress DR-IAP with IAP Standard Tunnel Protocol has the same
options available.

XPress™ DR Industrial Device Server User Guide 18

To install the unit

1. Connect a serial device to your XPress DR. See Serial Interface Connections for more
information about cable and connector specifications.

2. Connect an Ethernet cable to the Ethernet port.

3. Supply power to your XPress DR using a 9-30VDC or 9-24VAC source.

Note: The required input voltage is 9-30VDC, 9-24VAC (3 W maximum).

4. Supply power to the serial device.

Note: Connecting a device to an active Ethernet network can disrupt communications on the

network. Make sure the device is configured for your application before connecting to an active
network.

Required Information

Before configuring the XPress DR device server, have the following information available:

Hardware Address

Take note of the unit’s hardware address (also known as the Ethernet or MAC address.) It is on
the Product Information Label. The first three bytes of the hardware Address are fixed and read
00-80-A3, identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique
numbers assigned to each unit.

3: Installation of the XPress DR Device Server

00-80-A3-21-18-17 or 00:80:A3:21:18:17

Internet Protocol (IP) Address

The XPress DR device server must have a unique IP address on your network. This address
references the specific unit. By default, the unit is DHCP-enabled and automatically assigned an
IP address on DHCP-enabled networks. If you are assigning a static IP address, the systems
administrator generally provides the IP address, subnet mask, and gateway.

Note: The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP, and AutoIP. When the

units boots, it sends a DHCP broadcast to try and get an IP address. If it receives no reply from a
DHCP server, the XPress DR tries BOOTP. If the XPress DR does not receive a response from
BOOTP, it reverts to an AutoIP address.

IP Address: ______ ______ ______ ______

Subnet Mask: ______ ______ ______ ______

Gateway: ______ ______ ______ ______

You have several options for assigning an IP address and related network settings to your unit.
This chapter provides information about using the DeviceInstaller (graphical user interface) and
serial port login (command line interface) methods.

Note: For information about other methods of assigning the IP address, such as DHCP, AutoIP,

ARP, and Telnet, see Alternative Ways to Assign an IP Address.

Port Number

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 PBX system.

XPress™ DR Industrial Device Server User Guide 19

Method

Description

The unit's serial channel (port) can be associated with a specific TCP/UDP port number. Port
number 9999 is reserved for access to the unit's Setup (configuration) Mode window.

Methods for Assigning an IP Address

The unit's IP address must be configured before a network connection is available. You have the
following options for assigning an IP to your unit:

Table 3-1 Methods for Assigning IP Addresses

3: Installation of the XPress DR Device Server

DHCP

DeviceInstaller
(Recommended)

ARP and Telnet

AutoIP

Serial Port Login

A DHCP server automatically assigns the IP address and network settings. See

DHCP.

You can manually assign the IP address using a graphical user interface (GUI) on a
PC attached to a network.

You manually assign the IP address and other network settings at a command
prompt using a UNIX or Windows-based system. Only one person at a time can be
logged into the configuration port (port 9999). This eliminates the possibility of several
people simultaneously attempting to configure the unit. See ARP and Telnet.

This automatic method is appropriate when you have a small group of hosts rather
than a large network. This method allows the hosts to negotiate with each other and
assign addresses, in effect creating a small network. See AutoIP.

You initially configure the unit through a serial connection. See Assigning the IP

Address: Serial Port Login.

These methods are described in the remaining sections of this chapter.

Note: In most installations, a fixed IP address is desirable. The systems administrator generally

provides the IP address.

6: Configuration via Telnet or Serial Port (Setup

Mode)

You must configure the unit so it can communicate on a network with your serial device. As an
alternative to using a web browser, as described in the previous chapter, you can use the
following procedures remotely or locally:

 Use a Telnet connection to configure the unit over the network.
 Use a terminal or terminal emulation program to access the serial port locally.

The series of prompts at which you enter configuration settings is called Setup Mode.

Note: Detailed information about other setup methods is available from your Lantronix Sales

Associate.

The unit’s configuration is stored in nonvolatile memory and is retained without power. You can
change the configuration at any time. The unit performs a reset after the configuration has been
changed and stored.

This chapter tells you how to access Setup Mode and the general procedure for using it. To
complete the configuration, continue with chapters 7: Setup Mode: Server Configuration, 8:

Channel Mode: Channel Configuration, and 9: Setup Mode: Advanced Settings.

Note: The menus in the configuration chapters show a typical device. Your device may have

different configuration options.

Serial Port Connection

If you want to initially configure the unit through a serial connection, follow these steps:

1. Connect a console terminal or PC running a terminal emulation program to your unit's serial
port. The default serial port settings are 9600 baud, 8 bits, no parity, 1 stop bit, no flow
control.

2. To enter Setup Mode, cycle the unit's power (power off and back on). After power-up, the
self-test begins and the red Diagnostic LED starts blinking. You have one second to enter
three lowercase x characters (xxx).

Note: The easiest way to enter Setup Mode is to hold down the x key at the terminal (or

emulation) while powering up the unit.

3. At this point, the screen display is the same as when you use a Telnet connection. To
continue with a serial port login, go to Telnet Connection.

Exiting Setup Mode

There are two options through which to exit setup mode:

 Please protect your device from unauthorized access and follow the instructions below:
 Always select Y to enable Telnet/Web Manager password

Enable the enhanced password setting and create a strong 16-character password. For details,
see Security Settings (Option 6) on page 58.

Note: We do not recommend that you only use the 4-character basic password as it does not

offer sufficient security. Using no passwod is very dangerous.

Change Telnet/Web Manager password (N) ?

DHCP Naming

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 or Monitor Mode (see

11: Monitor Mode).

Note: 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.

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

 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 XX.XX.XX.XX (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).

Port Number

The port number functions as the TCP/UDP source port number for outgoing packets. Packets
sent to the unit with this port number are received to this channel. The port number selected is
the Incoming TCP/UDP port and Outgoing TCP/UDP source port. Port 0 is used when you want
the outgoing source port to change with each connection.

Port No (10001) ? _

Default setting for Port 1 is 10001. Range: 0-65535 except for the following reserved port
numbers:

Recommended ports, should be used for DeviceComm Manager
(COM1-COM256) or direct socket connections

Warning: We recommend that you not use the reserved port numbers for this setting as

incorrect operation may result.

Use Port 0 for the outgoing local port to change with each connection. The port range is 50,000­59,999. Each subsequent connection increments the number by 1 (it wraps back around to

50,000).

Only use this automatic port increment feature to initiate a connection using TCP. Set the port to
a non-zero value when the unit is in a passive mode or when using UDP instead of TCP.

Connect Mode

Connect Mode defines how the unit makes a connection, and how it reacts to incoming
connections over the network.

ConnectMode (C0) ? _

Enter Connect Mode options in hexadecimal notation. The default setting is C0.

Note: See Table 11-1 Binary to Hexadecimal Conversion Table. All bit positions in the table that

Manual Connection: When you use manual connection, you are not required to enter the entire
IP address if the IP is already configured as the remote IP address in the unit. 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): If you enable Autostart, the unit automatically connects to
the remote IP address and remote port specified when the firmware starts.

Hostlist: 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.

Datagram Type: When selecting this option, you will be prompted for the Datagram type. Enter
01 for directed or broadcast UDP.

XPress™ DR Industrial Device Server User Guide 51

8: Channel Mode: Channel Configuration

Modem (Emulation) Mode: In Modem 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 device servers, and to use
an Ethernet connection instead of a phone call, without having to change communications
applications and make potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), or
D7 (echo with 1-character response).

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), or D7 (echo with 1-character response).

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 (no echo) refers to the modem not
sending an answer to the commands received (or displaying what was typed).

To disconnect a connection using Modem Mode commands:

 There must be 1-second guardtime (no data traffic) before sending +++.
 There must not be a break longer that 1 second between +s.
 There must be another 1-second guardtime after the last + is sent.
 The unit acknowledges with an OK to indicate that it is in command mode.
 Enter ATH and press Enter. It is echoed if echo is enabled. ATH is acknowledged by another

OK.

Pack Control

Two firmware-selectable 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.

XPress™ DR Industrial Device Server User Guide 54

Idle Time: Idle time to "Force transmit" defines how long the unit should wait before sending
accumulated characters. This wait period is between characters. If there is an idle period between
characters equal to the force transmit set, then the unit will package up the serial data currently in
the buffer and send it to the network.

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

Send Characters: If 2-Byte Send Character Sequence is enabled, the unit interprets the
sendchars as a 2-byte sequence; if not set, they are interpreted 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 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)

Use this parameter to set an inactivity timeout. The connection is dropped if there is no activity on
the serial line before the set time expires. Enter time in the following format: mm:ss, where m is
the number of minutes and s is the number of seconds. To disable the inactivity timeout, enter
00:00.

DisConnTime (00:00) ? _

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

XPress™ DR Industrial Device Server User Guide 55

8: Channel Mode: Channel Configuration

Send Characters

You can enter up to two characters in hexadecimal representation in the parameters "sendchar."
If a character received on the serial line matches one of these characters, it is sent immediately,
along with any awaiting characters, to the TCP connection. This minimizes the response time for
specific protocol characters on the serial line (for example, ETX, EOT, etc.). Setting the first
sendchar to 00 disables the recognition of the characters. Alternatively, the two characters can be
interpreted as a sequence.

SendChar 1 (00) ? _
SendChar 2 (00) ? _

Telnet Terminal Type

This parameter appears only if the terminal type option is enabled in Disconnect Mode (see

DisConnMode above). If this option is enabled, you can use the terminal name for the Telnet

terminal type. Enter only one name.

Terminal name () ?

If the terminal type option is enabled, the unit also reacts to the EOR (end of record) and binary
options, which can be used 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
(see DisConnMode). If set, you can set a password on the serial port.

10: Firmware Upgrades

Obtaining Firmware

The XPress DR-IAP was designed to allow loading of vendor specific protocol firmware. This
firmware takes the place of the Standard Tunnel Protocol. Vendor specific protocols and the
software tools needed to load them can be found at www.lantronix.com/downloads

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

Once you load a vendor specific protocol, you must reference the user manual associated with
that protocol, since many of the setup and configuration dialogs will be changed. Some features,
such as web pages, may not be available with certain vendor protocols.

Note: If you change the protocol to a vendor specific protocol, you MUST reference the

associated protocol manual for setup and configuration information. The menu options shown in
this manual are for Standard Tunnel Protocol.

.

).

There are several ways to update the unit's internal operational code (*.rom): via TFTP, via
another unit, or via the serial port. You can also update the unit's internal web interface (*.cob) via
tftp or deviceinstaller.

The firmware files can be found at www.lantronix.com/downloads
Program Files\DeviceInstaller\Firmware folder. Here is a list of typical names for those files.
Check the Lantronix web site for the latest versions and release notes.

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. Make sure the Put and Binary options at the top of the window are selected.

3. Enter the full path of the firmware file in the Source File field.

4. In the Destination File field, enter the current internal operational code or WEB5 for the
internal Web interface. (DA=XPress Family IAP)

5. In the Remote Host field, enter the IP address of the unit being upgraded.

6. Click the Put button to transfer the file to the unit.

XPress™ DR Industrial Device Server User Guide 61

10: Firmware Upgrades

Figure 10-1 TFTP Dialog Box

The unit performs a power reset after the firmware has been loaded and stored.

Distributing Firmware to Another Unit

To distribute firmware to another unit over the network:

1. Enter the host unit's Monitor Mode (see Monitor Mode).

2. Send the firmware to the receiving unit using the SF command, where x.x.x.x is the receiving
unit's IP address: SF x.x.x.x

The receiving unit performs a power reset after the firmware has been loaded and stored.

Note: You can only update your unit 's internal Web interface using TFTP or DeviceInstaller.

Using HyperTerminal

The following procedure is for using the HyperTerminal software application. In some cases, the
HEX format file is available for download at www.lantronix.com/downloads

Before you can load firmware through the serial port you need to convert the ROM code to HEX
format. There is a DOS application, R2H.EXE that can be used to convert the ROM file to HEX
format. The R2H.EXE application is available at ftp://ftp.lantronix.com/pub.

Put R2H.EXE and the *.ROM file into the same directory on a PC then open a DOS Window to
that directory and type: C:\ R2H filename

This will create a filename.hex file that you can load via the serial port.

Note: Do not switch off the power supply during the update. A loss of power while

reprogramming will result in a corrupt program image and a nonfunctional unit.

To download firmware from a computer via the unit’s serial port:

1. Enter Monitor Mode via the serial port. (see Monitor Mode).

.

2. Download the firmware to the unit using the DL command.

3. Select Send Text File and select the *.HEX file to be downloaded. The downloaded file must
be the .HEX (ASCII) version.

12: Com Port Redirector

The Com Port Redirector allows any PC running the Microsoft® Windows® operating system to
use ports on a network server as if they were connected directly to the PC. The Redirector
creates a virtual COM port within Windows, which for most purposes acts just like the selected
serial port on the server. Whenever this virtual port is accessed, the redirector forms a network
connection to the server, and routes all data between the physical serial port on the server and
the virtual port within Windows. This allows a modem on a server to be shared by many PC
users, thus the name of "modem sharing" which is commonly used to describe this.

The Redirector support both IP and IPX. For IP, you must have IP installed and bound to your
network card, and a server which supports TCP socket connections to its serial ports. For IPX,
you must have IPX/SPX installed and bound to your network card, and the server must support
IPX/SPX connections to its serial ports.

12: Com Port Redirector

The Com Port Redirector software download and the Com Port Redirector Quick Start Guide are
available at www.lantronix.com/downloads

Problem/Message Reason Solution

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.

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.

Check the cables and wiring.

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

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

If the Ready 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. See the full list of Connect

Acquiring a Valid Setup Record

There are a number of ways to acquire a valid setup record:

 Copy the setup record of a properly configured device server via Monitor Mode (easiest

method).

 Request the setup record of a properly configured device server via another device server on

the network.

 Build the setup record in software.
 From a host PC, request the setup record of a properly configured device server via UDP.

To copy the setup record of a properly configured device server:

1. Configure a “master” device server with the desired parameters.

Figure B-1 Sample Setup Record in Intel Hex Format

XPress™ DR Industrial Device Server User Guide 73

2. Enter Monitor Mode on the master device server (see 11: Monitor Mode).

B: Network Configuration Using UDP

3. At the prompt, enter GC followed by a carriage return. The device server will respond with its
setup record in Intel Hex format.

4. Copy the setup record into a text file and save it for future use.

To request the setup record of a properly configured device server via another device server on
the network:

1. Make sure that both units are plugged onto the network properly.

2. Enter Monitor Mode (with network support enabled) on the unit that is not properly
configured. (see 11: Monitor Mode)

3. Issue the command GC x.x.x.x followed by a carriage return, where x.x.x.x is the IP address
of the properly configured device. The properly configured device will respond by sending its
setup record to the unit you are currently on. This configuration will be displayed in Intel HEX
format.

4. Copy that HEX string, and then issue the command SC. Now paste the copied string.

To build the setup record in software:

1. Create a 120-byte setup record.

2. Convert it to an Intel Hex record (see The Intel Hex Format).

3. Copy the setup record into a text file and save it for future use.

To request the setup record of a properly configured device server via UDP:

1. Configure a device server with the desired parameters and place it on the network.

2. From a host PC, send the F8 datagram to the device server (see Network Configuration

Using UDP). The device server responds with the F9 datagram, which includes its setup

record.

3. Send a previously saved setup record from a host PC via UDP.

Sending a Setup Record

There are also a number of ways to send a setup record to a device server:

 Send a previously saved setup record via Monitor Mode (easiest method).
 Send the setup record of a properly configured device server to another device server on the

network.

 Send a previously saved setup record from a host PC via UDP.

To send a setup record via Monitor Mode:

1. Configure a “master” device server with the desired parameters and place it on the network.

2. Place another device server (the “target”) on the network.

3. Enter Monitor Mode (with network support enabled) on the master device server (see

11: Monitor Mode.)

4. At the prompt, enter SC, the IP address of the target, and a carriage return.

5. Send the setup record to the target device server.

Note: For example, using HyperTerminal, copy the setup record and select “Paste to Host” to

send it to the device server. The device server reboots with the new configuration.

To send a previously saved setup record to a device server via UDP, from a host PC, send the
FA (or FD) datagram to the “target” device server (see Network Configuration Using UDP).

Note: The device server responds with the FB datagram. Refer to the table.

The Intel Hex Format

With this format, 8-bit binary data can be sent and received as ASCII text. The transmission is
blocked in records, and every record has its own checksum.

The record begins with a colon (:) and consists of a block length (2-character Hex), a 16-bit
address (4-character Hex), and a block type (2-character Hex). It is built by adding all binary 8-bit
values and taking the complement, so adding all byte values (including length, address, and type)
should yield zero.

Example:

00000001FF

End record, type 01, length 00, address 00 00, checksum FF.

01002000805F

Data record consisting of one byte (value 80 Hex) for address 0020 (32 decimal).

For communication with the node, the following block types are defined:

Table B-2 Block Types

Option Hex

To get and set the node configuration, 120 bytes should be exchanged at once in 32-Byte
records. The IP address in the record (bytes 0 to 3) will be ignored (unless the UDP FD command
is being used).

Calculating the Checksum

As mentioned in Table B-2 Block Types above, the last two characters of an Intel Hex setup
record represent a checksum of the data in the line. Since the checksum is a two-digit
hexadecimal value, it can represent a value from 0 to 255.

The checksum is calculated by summing the value of the data on the line and taking the two’s
complement of the sum.

Note: Do not include the leading colon or the checksum byte in the sum.

Example:

0300300002337A1E

Record length: 03 (3 bytes of data)
Address: 0030 (the 3 bytes will be stored at 0030, 0031, and 0032)
Record Type: 00 (normal data)
Data: 02, 33, 7A
Checksum: 1E

The two’s complement of E2 is 1E. See Calculating the Two’s Complement below.

Calculating the Two’s Complement

The two’s complement of a number is the value that must be added to the number to reach a
Hexadecimal value of 100 (256 in decimal). In the example above, E2 + 1E = 100.

You can also calculate the two’s complement by subtracting the sum from 100. Using the
example above again, 100 - E2 = 1E. It may help to use a scientific calculator.

Setup Records

A setup record consists of 120 bytes. They are transmitted at once from and to the node. Unused
bytes should be initialized as 00. Table B-3 Setup Record Construction defines the structure of a

Each TCP/IP node on a network host has a unique IP address. This address provides the
information needed to forward packets on the local network and across multiple networks if
necessary.

IP addresses are specified as x.x.x.x, where each x is a number from 1 to 254; for example,

192.0.1.99. The device server must be assigned a unique IP address to use TCP/IP network
functionality.

IP addresses contain three pieces of information: the network, the subnet, and the host.

Consider the IP address 36.1.3.4. This address is a Class A address; therefore, the network
portion of the address is 36.0.0.0 and the host portion is 1.3.4.

Subnet Portion

The subnet portion of the IP address represents which sub-network the address is from. Sub­networks are formed when an IP network is broken down into smaller networks using a subnet
mask.

A router is required between all networks and all sub-networks. Generally, hosts can send
packets directly only to hosts on their own sub-network. All packets destined for other subnets are
sent to a router on the local network.

Host Portion

The host portion of the IP address is a unique number assigned to identify the host.

Network Address

A host address with all host bits set to 0 addresses the network as a whole (for example, in
routing entries).

192.168.0.0

Broadcast Address

A host address with all host bits set to 1 is the broadcast address, meaning for “for every station.”

192.168.0.255

Network and broadcast addresses must not be used as a host address; for example, 192.168.0.0
identifies the entire network, and 192.168.0.255 identifies the broadcast address.

IP Subnet Mask

An IP subnet mask divides IP address differently than the standards defined by the classes A, B,
and C. An IP subnet mask defines the number of bits to be taken from the IP address as the
network or host sections. The device server prompts for the number of host bits to be entered and
then calculates the netmask, which is displayed in standard decimal-dot notation (for example,

255.255.255.0) when saved parameters are displayed.

Private IP Networks and the Internet

If your network is not and will not be connected to the Internet, you may use any IP address. If
your network is connected or will be connected to the Internet, or if you intend to operate the
device server on an intranet, you should use one of the reserved sub-networks. Consult your
network administrator with questions about IP address assignment.

Serial Interface

XPress DR has a single serial port that can be accessed by an RJ-45 connector or screw block
terminals. Both connectors support RS232 and RS485/422. By setting the switch located on the
face of the XPress DR, RS232 or RS485/422 can be selected.

Note: XPress DR is a single serial port device, meaning that only the RJ-45 or the screw

terminals can be used at a time. In the configuration menu, Channel 1 can refer to either the RJ­45 or the screw terminal currently being used.

RJ-45 Serial Connector

The serial RJ-45 serial connector supports up to 115200 bits per second and has the following
signals.

E: Alternative Ways to Assign an IP Address

E: Alternative Ways to Assign an IP Address

Earlier chapters describe how to assign a static IP address using DeviceInstaller, Web Manager,
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.

Provided a DHCP server exists on the network, it will assign the unit an IP address, gateway
address, and subnet mask when the unit boots up. The XPress DR has acquired an IP address if
the red LED stops flashing and the green Status LED is on continuously. (If no DHCP server
exists, the unit responds with a diagnostic error: the red Diagnostic LED blinks continuously, and
the green Status LED blinks five times. This blinking only continues for about 15 seconds.)

You can use the Lantronix® DeviceInstaller™ software to search the network for the IP your unit
has been assigned by the DHCP server and add it to the managed list. See Add the Unit to the
Manage List later in this chapter.

Note: This DHCP address will not appear in the unit’s standard configuration screens. You can

determine your unit’s DHCP-assigned IP address from the DHCP server, or in Monitor Mode.
When you enter Monitor Mode from the serial port with network connection enabled and issue the
NC (Network Communication) command, you will 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 automatically obtain an IP address in
smaller networks that may not have a DHCP server. A range of IP addresses (from 169.254.0.1
to 169.254.255.254) has been explicitly reserved for AutoIP-enabled devices. The range of Auto
IP addresses is not to be used 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, then 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 is not intended to replace DHCP. The unit will continue to look for a DHCP server on the
network. If a DHCP server is found, the unit will switch to the DHCP server-provided address and
reboot.

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.

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

An IP address is a 32-bit value, divided into four octets of eight bits each. The standard
representation is four decimal numbers (in the range of 0..255) divided by dots.

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

XPress™ DR Industrial Device Server User Guide 91

E: Alternative Ways to Assign an IP Address

192.2.1.123

This is called decimal-dot notation.

The IP address is divided in two parts: network and host. To support different needs, three
network classes have been defined. Depending on the network class, the last one, two or three
bytes define the host, while the remaining part defines the network. In the following explanations,
x stands for the host part of the IP address:

Class A Network

IP address 1.x.x.x to 127.x.x.x

Only 127 different networks of this class exist. These have a very large number of potential
connected devices (up to 16,777,216).

Example: 10.0.0.1, (network 10, host 0.0.1)

Class B Network

IP address 128.0.x.x to 191.255.xxx.xxx

These networks are used for large company networks. Every network can consist of up to 65,534
devices.

Example: 172.1.3.2 (network 172.1, host 3.2)

Class C Network

IP address 192.0.0.xxx to 223.255.255.xxx

These network addresses are most common and are often used in small companies. These
networks can consist of a maximum number of 254 hosts.

Example: 192.7.1.9 (network 192.7.1, host 9)

The remaining addresses 224.x.x.x - 239.x.x.x are defined as ”class D” and are used as multicast
addresses.

The addresses 240.x.x.x. - 254.x.x.x are defined as class E and are reserved addresses.

Network Address

The host address with all host bits set to 0 is used to address the network as a whole (in routing
entries, for example).

Broadcast Address

The address with the host part bits set to 1 is the broadcast address, meaning for every station.

Network and broadcast addresses must not be used as a host address (for example, 192.168.0.0
identifies the entire network and 192.168.0.255 identifies the broadcast address).

IP Netmask

The netmask is used to divide the IP address differently from the standard defined by classes A,
B, C. A netmask defines how many bits from the IP address are to be taken as the network
section and how many bits are to be taken as the host section. When the number of host bits is
entered, the XPress DR calculates the netmask. The netmask is displayed in standard decimal­dot notation.

XPress™ DR Industrial Device Server User Guide 93

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) method from UNIX
and Windows-based systems to assign a temporary IP address.

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 (Unix)

arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)

Note: For the ARP command to work on Windows operating system (OS), the ARP table on

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

2. 1.1. If you are using Windows OS, 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

E: Alternative Ways to Assign an IP Address

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.

F: Binary to Hex Conversion

Many of the device server’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

The following are two simple ways to convert binary numbers to hexadecimals.

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, 0010 0011) to a hexadecimal representation,
the upper and lower four bits are treated separately, resulting in a two-digit hexadecimal number
(in this case, 4C).

Use the following table to convert values from binary to hexadecimal.

Table F-1 Binary to Hexadecimal Conversion Table

Decimal Binary Hex

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 ProgramsAccessoriesCalculator.

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

3. Select Bin (Binary), and type the number to convert.
