Introduction

1. Introduction

This manual describes the family of Universal Device Servers (UDS), including the UDS-10
Device Server and the UDS-10-IAP Device Server with Industrial Automation Protocols. The
UDS-10B Embedded Device Server is shown here for reference only. It is part of the UDS-10
family but is described in the Embedded Integration Kit (EIK) User Manual. For all practical
purposes, it is the same as the UDS-10 but has no external metal case.

Most of the material in this manual applies to all of the UDS-10 products. However, in some
cases there will be some features that apply to only one product. In those cases, a note will
explain the variation.

Note: In most cases UDS-10 refers to UDS-10, UDS-10-IAP and UDS-10B.

UDS-10 User Guide 1-1

Introduction

1.1 UDS-10

The UDS-10 Device Server connects serial devices to Ethernet networks using the IP
protocol family (TCP for connection-oriented stream applications and UDP for datagram
applications). A few of the different types of serial devices supported are listed below:

• Time/Attendance Clocks and Terminals

• ATM Machines

• CNC Controllers

• Data Collection Devices

• Universal Power Supply (UPS) Management Units

• Telecommunications Equipment

• Data Display Devices

• Security Alarms and Access Control Devices

• Handheld Instruments

• Modems

The UDS-10 connects these devices through a TCP data channel or through a Telnet
connection to computers or another Device Server. Datagrams can be sent by UDP.

The UDS-10 supports RS-232, RS-422/485 via its DB-25F serial port. It supports 10Mb/s
Ethernet through the RJ-45 connector. It can be configured via HTTP, SNMP, DHCP or
Telnet. It contains a Flash ROM for easy software upgrades.

UDS-10 User Guide

Introduction

1.2 UDS-10B

Note: This section is for the UDS-10B only.

The UDS-10B is the embedded version of the UDS-10, and is designed to be easily and
quickly integrated into products. The UDS-10B operates the same as the UDS-10, except the
UDS-10B has no external metal case. Serial interface is accomplished via a female DB25
(DCE) connector which provides the necessary signals for both RS232 and RS422/RS485
interfaces.

In addition, an RJ45 (10BASE-T) connector is available for Ethernet access. It will support
network speeds of 10Mbps.

The UDS-10B board comes with various power supply options:

• a power jack for 9-30 VDC or 9-24 VAC with maximum 140mA.

• power via the DB25 inputs at either the regulated +5 VDC with maximum 200mA or

the unregulated 9-30 VDC.

The UDS-10B’s well-developed IP firmware supports protocols such as ARP, UDP, TCP,
Telnet, ICMP, SNMP, BOOTP,DHCP, TFTP, AutoIP, HTTP, and custom protocols.

Note: Please see the EIK, Embedded Integration Kit user manual, 900-226, for information
on using the UDS-10B Embedded Device Server.

Introduction

1.3 UDS-10-IAP Device Server

Note: This section is for the UDS-10-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 1 – UDS-10-IAP

Lantronix provides IAP Device Servers specifically designed for different industrial
environments.

• CoBox-DR1-IAP, with a DIN rail interface for harsh environments or alongside

controls instruments in electrical panels.

• CoBox-FL-IAP, with fiber connectivity for long cable runs or electrically hazardous

environments.

• UDS-10-IAP, a compact Device Server for use in less demanding environments.

UDS-10 User Guide

Introduction

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

• Barcode scanners

• Label printers

• Most factory floor serial devices

1.3.1 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. The suite of protocols include DF1 (Rockwell
Automation) and Modbus (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.

For information about using any of the industrial communication protocols, see the user
manuals on the software CD or our web site. Protocol firmware files are also contained on the
CD and new versions are available from the Lantronix web site.

You can set up the unit using the serial port, or remotely over Ethernet using Telnet or 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. IAP Device Servers use Flash memory for
maintenance-free, non-volatile storage which allows for fast system upgrades.

UDS-10 User Guide 1-5

Introduction

1.4 Network Protocols

Note: UDS-10 refers to UDS-10, UDS-10-IAP and UDS-10B except where noted.

The UDS-10 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
point-to-point connection, UDP datagram is used.

1.4.1 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
UDS-10 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.

1.4.2 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 UDS-10’s
serial port. See IP Addresses on page 10-1 for a complete description of IP Addressing.

1.4.3 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 UDS-10, a port number can be configured on the channel (port). The UDS-10 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.

2. Getting Started

This section describes all the procedures for configuring your unit. For a short version, see
the Quick Start Guide. Go to the Lantronix web site for the latest firmware and release notes.

UDS-10 comes with Standard Tunnel Protocol and the UDS-10-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 UDS-10-IAP users, see Industrial Automation Protocols on page 1-5

Loading industrial protocols to a UDS-10-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 on the
software CD. This section describes the setup and configuration dialogs for the Standard
Tunnel Protocol.

Note: The following information is based on the condition that a UDS-10 is loaded with
Standard Tunnel Protocol. The UDS-10-IAP with IAP Standard Tunnel Protocol may have
different options available.

2.1 Addresses and Port Number

2.1.1 Ethernet (MAC) Address

The Ethernet address is also referred to as the hardware address or the 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.

00-20-4A-21-18-17 or 00:20:4A:21:18:17

2.1.2 Internet Protocol (IP) Address

Every device connected to an IP network must have a unique IP address. This address is used
to reference the specific unit.

UDS-10 User Guide 2-1

Getting Started

2.1.3 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.

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.

2.2 Physically Connecting the Unit

2.3 Methods of Assigning the 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:

Method Description

DHCP A DHCP server automatically assigns the IP address and network

settings. See
DeviceInstaller
(Recommended)

ARP and Telnet You manually assign the IP address and other network settings at a

AutoIP This automatic method is appropriate when you have a small group of

You manually assign the IP address using a graphical user interface

(GUI) on a PC attached to a network. See DeviceInstaller on page 2-5.

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

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

Port Login on page 2-12.

DHCP on page 2-4.

ARP and Telnet on page 2-11.

AutoIP on page 2-4.

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. Obtain the following information before starting to set up
your unit:
IP Address: ___ ___ ___ ___
Subnet Mask: ___ ___ ___ ___
Gateway: ___ ___ ___ ___

UDS-10 User Guide 2-3

Getting Started

2.3.1 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 DR1 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 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.

2.3.2 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 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.

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.

2-4

UDS-10 User Guide

Getting Started

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

2.4 DeviceInstaller

You can manually assign the IP address using DeviceInstaller software, which is found on the
product CD. If you want to use a serial connection instead of an Ethernet connection to
configure the device, go to Serial Port Login on page 2-12.

2.5 ARP and Telnet

The unit’s IP address must be configured before a network connection is available. You are
able to ARP an address into a CoBox/UDS device even if there is already an address in the
unit. 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. If you want to
initially configure the unit through the network, follow these steps:

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, which is found on the product
label on the bottom of the unit. Some UNIX hosts use colons “:” between hardware
octets, and some use dashes “-“. All Windows hosts use dashes.

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 will fail quickly, but the unit will
temporarily change its IP address to the one designated in this step.

telnet 191.12.3.77 1

4. Finally, open a Telnet connection to port 9999, and press Enter within three seconds to go
into Setup Mode. If you wait longer than three seconds, the unit will reboot and you will
need to perform step 3 again.

telnet 191.12.3.77 9999

5. Set all required parameters

Note: The IP address you just set is temporary and will revert to the default value when the
unit 's power is reset unless you log into the unit and store the changes permanently. Refer to
the chapter on configuration for instructions on permanently configuring the IP address.

UDS-10 User Guide 2-11

Getting Started

2.6 Serial Port Login

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.

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 Using a Telnet Connection on page 3-10.

3. Configuring the Unit

You must configure the unit so that it can communicate on a network with your serial device.
For example, you must set the way the unit will respond to serial and network traffic, how it
will handle serial packets, and when to start or close a connection. You can configure your
unit locally or remotely using the following procedures:

• Use a standard Web browser to access the unit’s internal Web pages and configure

the unit over the network. This is the easiest and preferred method.

• 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 unit’s configuration is stored in nonvolatile memory (NVRam) 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.

Note: The configuration menus in this section show a typical device and all of the possible
configuration options. Your device may have different configuration options.

3.4.2 Using the Serial Port

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

8. 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.

9. 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.

10. 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 Using a Telnet Connection on page 3-10.

3.5 Server Configuration (Network Configuration)

These are the unit’s basic network parameters. The following parameters are displayed when
you select Server configuration.

IP Address : (000) .(000) .(000) .(000)

3.5.1 IP Address

The IP address must be set to a unique value in your network. See Methods of Assigning the
IP Address on page 2-3 for more information about IP addressing.

3.5.2 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.

3.5.3 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
section.

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
is displayed in standard decimal-dot notation when the saved parameters are displayed (for
example, 255.255.255.0).

3.5.4 Change Telnet configuration password

Setting the Telnet configuration password prevents unauthorized access of the setup menu via
a Telnet connection to port 9999 or via Web pages. The password is limited to 4 characters.
An enhanced password setting of 16 characters is available under Security Settings for Telnet
access only.

Note: No password is required to access the Setup Mode window via a serial connection.

3.5.5 DHCP Naming

There are 3 methods for assigning DHCP names to these products.

1) 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 will default 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.

2) Custom DHCP name. You can create your own DHCP name on these products. If you are

using an IP address of 0.0.0.0, then the last option in "Server configuration" will be "Change
DHCP device name". The "Change DHCP device name" option will allow you to change the
DHCP name to an alpha numeric name.

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

3) Numeric DHCP name. You are able to change the DHCP name by specifying the last

octet of the IP address. When you use this method, the DHCP name will be 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 will be LTX12. This method will only work with 2 digit

numbers (0-99).

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.

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

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.

3.6.10 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.

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

Note: See Table 35 - Binary to Hexadecimal Conversion Table.

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.

UDS-10 User Guide 3-23

Configure

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.

3.6.11 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.

3.6.12 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 (see Pack Control on page 3-23).

3.6.13 Telnet Terminal Type

This parameter appears only if the terminal type option is enabled in Disconnect Mode (see
DisConnMode on page 3-21 above). If this option is enabled, you can use the terminal name
for the Telnet terminal type. Enter only one 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.

3.6.14 Channel (Port) Password

This parameter appears only if the channel (port) password option is enabled in Disconnect
Mode (see DisConnMode on page 3-21). If set, you can set a password on the serial port.

4. Updating Protocol (Firmware)

4.1 Protocol Firmware

You can update the unit's internal operational code to a newer revision, or change the code to
operate with a specific vendor.

The UDS-10-IAP was designed to allow loading of vendor specific protocol firmware. This
firmware takes the place of the IAP Standard Tunnel Protocol. Vendor specific protocols and
the software tools needed to load them can be found on the software CD.

You can obtain the most up-to-date protocol firmware and release notes for the unit from the
Lantronix Web site (www.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.

) or by using anonymous FTP (ftp.lantronix.com).

4.2 Reloading Protocol Firmware

There are several ways to update the unit's internal operational code (*.ROM): via
DeviceInstaller (the preferred way), 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 are located on the software CD in the firmware folder. Here is a list of
typical names for those files. Check the Lantronix web site for the latest versions and release
notes.

Firmware

4.2.4 Via the Serial Port

The following procedure is for using the HyperTerminal software application. In some cases,
the HEX format file is available on the software CD and on the Web site.

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 on page 7-1).

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.

4. After the final record is received, the unit checks the integrity of the firmware image
before programming the new firmware in the flash ROM. The following message
displays when the firmware upgrade is complete.

5. DeviceComm Manager

Lantronix DeviceComm Manager is a Windows based COM port redirector software utility.
Its function is to redirect customer application data destined for a local serial (COM) port to
the PC’s network port. Rather than going out the local serial port, the data is transmitted
across the Ethernet network port using the TCP/IP protocol.

A Device Server attached to the network receives the data and presents it on its serial port.
Conversely, data into the serial port of the Device Server is sent back over the network to the
DeviceComm Manager. The DeviceComm Manager then presents the data to the customer
application as if it were from a local serial COM port.

Customer
Application

This powerful 32-bit Windows utility allows any commercially available or application­specific software to communicate with networked devices as if they were directly attached to
the PC's COM ports. To the user, this means that when they network-enable a serial device
with a Lantronix Device Server, they can retain their existing PC-based applications software
without having to undertake the additional time and expense of developing new software.

Using simple on-screen menus, users can map up to 255 COM ports directly to IP addresses
assigned to Lantronix Device Servers. Once COM ports are mapped, any networked PC with
DeviceComm Manager software installed can access devices on the network via Lantronix’
Device Servers. Both the software application and the serial device operate normally as if
they were still directly connected - Lantronix Device Server and the DeviceComm Manager
utility do all the work in between to keep data flowing smoothly.

The DeviceComm Manager utility consists of a Control Panel applet, a device driver, and a
Windows service.

• Eliminates the need for the users to develop or modify their existing application software

• No understanding of how to develop networking software is required

• Everything is totally transparent to the serial device, the application software, and the user

• Redirects up to 255 COM ports simultaneously over TCP/IP protocol

• Provides raw mode data only, which means it will not change or modify the data being sent

• Supports Windows 2000, Windows NT4.0, and Windows XP

• Easy to install and even easier to configure

****Please Note:****
Because this is a raw mode redirector:
a. On UDS and CoBox products, you cannot use ports 14000 through 14009.
b. On MSS, ETS, LRS, and SCS products DO use the 3001, 3002, 3003, etc. ports.

Note: You will be required to reboot your system when enabling COM ports. You may want
to set them all up at one time and then reboot.

7. Click the Settings button for advanced configuration. Some serial applications do not
work well when redirected because they are not expecting the latency (delay) that an
Ethernet network may cause. Increasing the “Read Network Timeout” and the “Write
Network Timeout” values may help the situation. Network latency varies depending on a
number of factors. You can get a rough idea of the delay at a given time by “pinging” the
device server from the PC and looking at the “time” column. You may also find the PC
command “tracert” helpful. See your Windows OS documentation for more details on
these commands. Both “ping” and “tracert” are DOS prompt commands.

8. Click Ok to close the Settings dialog box.

9. Select the "Enable Connection Status” checkbox at the bottom of the DeviceComm
Manager screen if you wish to be notified via screen pop-up when the connection to the
remote port is established. If your application is very time sensitive regarding the initial
connection, or you do not wish to have a screen pop-up, leave this box unchecked.

10. Click OK to complete the setup.

No other setup is required. In the above example, all data sent to COM4 will be sent across
the network to the device server at “172.20.197.50”, port “10001”.

When you Telnet into port 1 on
the UDS/CoBox, you are only
assigning a temporary IP
address. When you Telnet into
port 9999 and do not press Enter
quickly, the UDS/CoBox will
reboot, causing it to lose the IP
address.

You did not press Enter quickly

seconds to press Enter before
the connection is closed.

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 UDS/CoBox 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.

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

Telnet back into 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 message “Press Enter to go
into Setup Mode.”

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 with
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 UDS/CoBox.
Make sure that the Link LED is lit.
If the Link LED is not lit, then the
UDS/CoBox is not properly

8.2 Configuring Multiple Devices

When configuring a number of Device Servers identically, it is useful to create a template
setup record. The setup record can then be sent to the “target” Device Servers from a
“master” Device Server via “cut and paste” or UDP (see Network Configuration using UDP
on page 8-1).

Device Servers use a 120-byte setup record in Intel Hex format. This format facilitates the
transfer of binary data using ASCII characters. See Setup Records on page 8-7 and The Intel
Hex Format on page 8-5 for information about setup records and converting them to Intel
Hex format.

8.2.1 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.

2. Enter Monitor Mode on the master Device Server (see Monitor Mode on page 7-1).

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.

UDS-10 User Guide 8-3

UDP

To request the setup record of a properly configured Device Server via another Device Server
on the network:

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

6. Enter Monitor Mode (with network support enabled) on the unit that is not properly
configured. (see Monitor Mode on page 7-1)

7. 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.

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

The unit will not reboot on its own. You must reboot the unit before the settings take effect.

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 on page 8-5).

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 on page 8-1). 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.

8.2.2 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.

UDS-10 User Guide

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

Monitor Mode on page 7-1)

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 on page 8-1).

Note: The Device Server responds with the FB datagram. Refer to the table.

8.2.3 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 20 - Block Types

Option Hex

Data block program memory (firmware) 00
End record 01
Data block configuration memory 10

UDS-10 User Guide 8-5

UDP

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).

8.2.4 Calculating the Checksum

As mentioned in Table 20 - 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

03 + 00 + 30 + 00+ 02 + 33 + 7A = E2

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

8.2.5 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.

8.4 IP Addresses

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.

8.4.1 Network Portion

The network portion of the IP address is determined by the network type: Class A, B, or C.

Table 31 - Network Portion of IP Address

Network Class Network Portion of Address

Class A First byte (2nd, 3rd, and 4th bytes are the host)
Class B First 2 bytes (3rd and 4th bytes are the host)
Class C First 3 bytes (4th byte is the host)

In most network examples, the host portion of the address is set to zero.

Table 32 - Available IP Addresses

Class Reserved Available

A 0.0.0.0

127.0.0.0

B 128.0.0.0

191.255.0.0

C 192.0.0.0

128.1.0.0 to 191.254.0.0

192.0.1.0 to 223.255.254.0

None (Check this)

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.

8.4.2 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.
