Introduction

11.. IInnttrroodduuccttiioonn

This manual describes the CoBox-FL family of Device Servers, including the CoBox-FL
Device Server and the CoBox-FL-IAP Device Server with Industrial Automation Protocols.

Most of the material in this manual applies to all of the CoBox-FL 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 CoBox-FL refers to CoBox-FL and CoBox-FL-IAP.

1.1 CoBox-FL

The CoBox-FL 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 CoBox-FL 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 CoBox-FL supports RS-232, RS-422/485 through the DB-25F Channel 1 serial port. It
supports RS-232 through the DB-9M Channel 2 serial port. It supports 10Mb/s Ethernet
through an RJ-45 connector and through ST-Fiber connectors. It can be configured via HTTP,
SNMP, DHCP or Telnet. It contains a Flash ROM for easy software upgrades.

Introduction

1.2 CoBox-FL-IAP Device Server

Note: This section is for the CoBox-FL-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 – CoBox-FL-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.

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

1.2.1 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.

Introduction

1.3 Network Protocols

Note: CoBox-FL refers to CoBox-FL and CoBox-FL-IAP except where noted.

The CoBox-FL 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.

1.3.1 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
CoBox-FL 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.

1.3.2 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 CoBox­FL’s serial port. See Appendix A for a complete description of IP Addressing.

1.3.3 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 CoBox-FL, a port number can be configured on the channel (port). The CoBox-FL 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.

1.4 Serial Interface

The CoBox-FL has two serial ports. CH 1 uses a DB-25F (DCE) connector and supports RS­232, RS-422/485. CH 2 uses a DB-9 connector and supports RS-232 only. It supports 10Mb/s
Ethernet through the RJ-45 (10BASE-T) connector or the ST-Fiber (10BASE-FL). It can be
configured via HTTP, SNMP, DHCP or Telnet. It contains a Flash ROM for easy software
upgrades.

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.

CoBox-FL comes with Standard Tunnel Protocol and the CoBox-FL-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 CoBox-FL-IAP users, see Industrial Automation Protocols on page 1-3

Loading industrial protocols to a CoBox-FL-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 CoBox-FL is loaded with
Standard Tunnel Protocol. The CoBox-FL-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.

CoBox-FL 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

Serial Port Login You initially configure the unit through a serial connection. See Serial

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: ___ ___ ___ ___

CoBox-FL 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 CoBox-FL has acquired an IP address
if the red LED stops flashing and the green GL 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 GL LED blinks five times. This blinking only continues for about 5 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.

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

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

inten n the product

ded IP address and the hardware address of the unit, which is found o
label on the bottom of the unit. Some UNIX hosts use colons “:” betwe
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;
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 fo

llowing 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 t
into Setup Mode. If you wait longe

o port 9999, and press Enter within three seconds to go

r than three seconds, the unit will reboot and you will

need to perform step 3 again.

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 yo
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.

3.5.5 DHCP Naming

There are 3 methods for assigning DHCP names to th

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 nam

e. 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 "Chan
DHCP device name". The "Change DHCP device name" option will allow you to change
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, t
YY is what you chose for the last octet of the IP address. If the IP address you specify

he DHCP name will be LTXYY where

is

0.0.0.12, then the DHCP name will be LTX12. This method will only work with 2 digit

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

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.

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.

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.
