XPress DR+ User Guide 11

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. Information specific to the wireless version of the XPress DR+ unit is in

Chapter 4: XPress DR+W.

Note: In this User Guide we sometimes refer to the XPress DR+W as "the wireless unit"

or the "wireless device server."

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 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

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)

Note: For a diagram and description of XPress DR+W, see Front Panel

Description on page 31.

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.

XPress DR+ User Guide 13

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 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 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 serial port 1 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.

Chapter 2: Introduction

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.

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.

XPress DR+ User Guide 14

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.

Using a method called serial tunneling, the XPress DR+ encapsulates serial data
into packets and transports them over Ethernet. Using two XPress DR+ units,
connected by a network, you can extend virtual serial connections across a
facility or around the world.

Figure 2-2. Example of Serial Tunneling

Chapter 2: Introduction

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.

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

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.

XPress DR+ User Guide 16

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 Chapter 5: Using DeviceInstaller.)

Web Manager: Through a web interface, configures the XPress DR+ settings using the
Lantronix Web Manager. (See Chapter 6: 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. To use DeviceInstaller for
communication to an XPress DR+W over a wireless network, the WLAN network settings
must be configured first.

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 full and half-duplex modes, as well as
automatic MDI/MDIX crossover, allowing use of both straight-through and crossed
Ethernet cables. The unit also supports IEEE 802.1d spanning tree, which protects
against the possibility of a network loop.

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. The XPress DR+W
provides a fully integrated solution that combines an operating system, embedded Web
server, full TCP/IP protocol stack with an 802.11b/g transceiver supporting WEP and
WPA security.

Application Examples

The XPress DR+W has an 802.11b/g transceiver in addition to its serial and Ethernet
ports. Each serial port is connected to the serial communication port of a device. The
wireless transceiver connects to another wireless device or to an Access Point (AP). This
section includes typical scenarios for using the 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. The PC makes a direct wireless connection

XPress DR+ User Guide 29

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. Direct XPress DR+W - to- XPress DR+W Connection

In the example above, two XPress DR+W s have established an Ad Hoc peer-to-peer
relationship. They communicate directly to each other’s serial devices without a PC or an
AP.

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 WPA2/802.11i security are only available in infrastructure

mode.

Installing the XPress DR+W for Initial Configuration

Two settings are required for the XPress DR+W to communicate on a wireless network:

 The Server (0) settings

 The WLAN (4) settings

Complete the following steps to connect and initially configure the XPress DR+W
required settings. Initial configuration is done using the Setup Mode’s Change Setup
menu.

1. Connect one end of the supplied serial cable to the unit’s serial port 1. (See 9-Pin

RS-232 to Serial RJ45 Cable (P/N 500-103) on page 22.)

2. Connect the other end of the serial cable to a terminal or a PC’s serial COM port.

3. On the PC, open a terminal emulation application (e.g. HyperTerminal). Configure the
XPress DR+W serial settings as 9600 baud, 8 bits, not parity, 1 stop bit, and no flow
control (9600, 8, N, 1).

4. Enter Setup Mode by simultaneously connecting the power supply and holding down
the x key. Upon connection, the following information displays:

5. Press Enter within 5 seconds to display the Change Setup menu.

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.

IP Address : (000) (000) (000) (000) _

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.

Table 4-2. BootP/DHCP/AutoIP options

Options Bit

AutoIP 0 1

DHCP 1 2

BootP 2 4

Value

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.

WLAN Configuration (Option 4)

Without adequate protection, a wireless LAN is susceptible to access by unauthorized
users. For that reason, XPress DR+W features the WPA security standard, based on
IEEE802.11i. WEP is provided for backwards compatibility and interaction with older
devices.

Note: Due to regulations, the country-specific setting has been removed from the setup

menu and Web Manager. We provide a separate utility for changing the Country/Zone
setting. The utility is called SetZone and is included in the XPress DR+W package. It is
also available for download from the Lantronix web site.

The syntax is SetZone <IP address> [<zone abbreviation>]

XPress DR+ User Guide 35

Adhoc Network Channel

When Adhoc is selected in the Topology parameter, and the XPress DR+W cannot find
the specified network, it creates one with that name by transmitting a beacon on the
selected channel.

Channel (11) ? _

Only channels allowed in the country for which the XPress DR+W is designated can be
selected. The country displays in the Setup Mode settings overview.

Security

The Security Suite prompt enables you to select the type of security. The XPress DR+W
features WEP, WPA and WPA2/802.11i to secure all wireless communication. WPA and
WPA2/802.11i are only available when the topology is Infrastructure.

Notes:

 In the WPA and WPA2 modes, the encryption setting denotes the lowest acceptable

encryption method, CCMP > TKIP > WEP. For example, if the unit is configured for
WEP, and the Access Point supports TKIP, the negotiation will result in TKIP being
used. If the unit is configured for TKIP, and the Access Point only supports WEP,
association will fail because the Access Point does not meet the unit's demands.
(CCMP is only available in WPA2 mode.)

 Communication between the Access Point and a single wireless device is called

unicast and uses the pairwise encryption method. Communication from the Access

XPress DR+ User Guide 36

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.

A group encryption lower than the pairwise encryption is necessary to use higher
security with the XPress DR+W than other devices connecting to the same
Access Point can support.

 CCMP is also called AES on products of other manufacturers. CCMP is an

extension of AES. It provides the strongest current encryption method.

WEP

Authentication selects whether the encryption keys are matched (1 = shared) with those

of the communication partner before passing through messages or not (2 = open/none).

The Encryption prompt requests the length of the encryption key and the security
strength. WEP64 uses a 40 bits/5 bytes key (option 1). WPE128 uses a 104 bits/13 bytes
key (option 2).

Select Y (Yes) at the Display current key prompt to show the currently configured
key/passphrase.

Select Y (Yes) at the Change key prompt to be able to modify the currently configured
key.

The Key type indicates whether the new key is in hexadecimal or passphrase format.

Enter key prompts for the new encryption key.

Key Type Encryption Key

Hex Enter the Encryption Key as a hexadecimal value according the following

guidelines:

 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-xx-

xx-xx-xx-xx-xx-xx.
Example: A1-B2-C3-E4-D5-F6-98-74-B7-65-A8-D3-F2

Passphrase

Enter the key as a string. A passphrase is a sentence that is translated into
hex by a hashing algorithm.
Example: My dog has spots and likes to chase cats.

A passphrase of more than 20 characters is recommended. Maximum length
is 63 characters. Spaces and punctuation characters are permitted.

XPress DR+ User Guide 37

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. In case the WEP key is entered as a passphrase, the
four WEP keys are generated according to the Linksys algorithms and will be
different.

WPA

This firmware version allows only Pre-Shared Keys (PSK) for authentication.

Select Y (Yes) at the Display current key prompt to show the currently configured

Assigning an IP Address

Note: To use DeviceInstaller for communication to an XPress DR+W over a wireless

network, you must first configure the network and WLAN settings using a serial
connection.

The XPress DR+'s IP address must be configured before the unit can work correctly on a
network. You have several options for assigning an IP to your unit. We recommend that
you manually assign the IP address over the network using DeviceInstaller software,
which is on the product CD.

The unit’s IP address is normally set to 0.0.0.0 at the factory. The hardware address is on
the product label. The unit is DHCP-enabled as the default.

To assign an IP address manually:

1. Click StartÆPrograms Æ LantronixÆDeviceInstallerÆDeviceInstaller. If your PC
has more than one network adapter, a message displays. Select an adapter and click
OK.

Server Configuration (Option 0)

You can configure the unit’s basic network parameters when you select Server
configuration (option 0).

Note: Current values display in parentheses.

Network Mode (XPress DR+W only)

The first prompt requires you to set the unit for wired or wireless use. Wired is the
default.

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.

IP Address : (000) (000) (000) (000) _

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.

Value

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 ((000) (000) (000) (000)_

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 89.

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.

 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.

Chapter 8: Setup Mode: Server Configuration

 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).

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
50,000 to 59,999. 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.

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.

XPress DR+ User Guide 73

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. (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.

XPress DR+ User Guide 74

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. 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.

XPress DR+ User Guide 75

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.

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).

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.

XPress DR+ User Guide 76

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.

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.

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.

Alternate Packing Algorithm (Pack Control)

Enable 1

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.

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)

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

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.

XPress DR+ User Guide 81

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 80).

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.

Chapter 9: Setup Mode: Channel Configuration

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.

WLAN Settings (XPress DR+W Only)

Note: To use DeviceInstaller for communication to an XPress DR+W over a wireless

network, you must first configure the network and WLAN settings using a serial
connection. See Chapter 4:XPress DR+W.

Before the XPress DR+W can communicate on an 802.11b/g wireless network, the
WLAN settings must match the wireless network. By default, the XPress DR+W is set to
Ad Hoc network mode, and its wireless Network Name (SSID) is LTRX_IBSS.

Note: Due to regulations, the country-specific setting has been removed from the setup

menu and Web Manager. We provide a separate utility for changing the Country/Zone
setting. The utility is called SetZone and is included in the XPress DR+W package. It is
also available for download from the Lantronix web site (www.lantronix.com

The syntax is SetZone <IP address> [<zone abbreviation>]

).

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:

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.

Only channels allowed in the country for which the XPress DR+W is designated can be
selected. The country displays in the Setup Mode settings overview.

Security

The Security Suite prompt enables you to select the type of security. The XPress DR+W
features WEP, WPA and WPA2/802.11i to secure all wireless communication. WPA and
WPA2/802.11i are only available when the topology is Infrastructure.

Notes:

 In the WPA and WPA2 modes, the encryption setting denotes the lowest acceptable

encryption method, CCMP > TKIP > WEP. For example, if the unit is configured for
WEP, and the Access Point supports TKIP, the negotiation will result in TKIP being
used. If the unit is configured for TKIP, and the Access Point only supports WEP,
association will fail because the Access Point does not meet the unit's demands.
(CCMP is only available in WPA2 mode.)

 Communication between the Access Point and a single wireless device is called

unicast and uses the pairwise encryption method. Communication from the Access

XPress DR+ User Guide 83

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.

A group encryption lower than the pairwise encryption is necessary to use higher
security with the XPress DR+W than other devices connecting to the same
Access Point can support.

 CCMP is also called AES on products of other manufacturers. CCMP is an

extension of AES and is the correct term. It provides the strongest current encryption
method.

WEP

Authentication selects whether the encryption keys are matched (1 = shared) with those

of the communication partner before passing through messages or not (2 = open/none).

The Encryption prompt requests the length of the encryption key and the security

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. 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 25.

Table 13-1. 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.

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.

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.
