1: Introduction
The IAP Family of Device Servers
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 tobe established over Ethernet and IP networks. As a result, direct serial
connections can be extended within the plant, throughout the facility, and across the global
enterprise.
Existing COM-port-based WindowsTM applications can access network-enabled serial
devices, using Comm Port Redirector TM software. Redirector allows the creation of virtual
serial ports, which can be mapped to remote Device Servers over Ethernet. When used in
conjunction with an OPC server, most Windows based HMI, SCADA, and PC based
control applications have full access to information in the connected device.
Lantronix provides IAP Device Servers specifically designed for different industrial
environments:
u CoBox-DR1-IAP, with a DIN rail interface for harsh environments or alongside
controls instruments in electrical panels.
u CoBox-FL-IAP, with fiberconnectivity for long cable runs orelectrically hazardous
environments.
u UDS-10-IAP, a compact design Device Server for use in less demanding
environments.

Key Features Introduction

A few examples of attached devices are:
u PLCs
u AC/DC drives
u CNC systems
u Operator panels and message displays
u Process Controls
u Instrumentation
u Power monitoring equipment
u Scales and weighing systems
u Barcode scanners
u Label printers
u Most factory floor serial devices
Key Features
IAP Device Servers, adapted to the three factory environments, will 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 IAP Device Servers feature installable industrial communication protocols.
Lantronix’s Automation Protocols Suite (APS) includes protocols such as DF1 (Rockwell
Automation) and Modbus (Schneider Electric). Where the Standard Tunneling protocol is
limited to exclusive, device-to-device connections, the industrial protocols offer
connections to other devices simultaneously.
You can configure the unit using the serial port, or remotely over the network using Telnet
or a web browser. The APS CD (the CD that comes with your Device Server) includes
Windows-based configuration software that simplifies the process of installing protocols
and configuring them for use with attached devices. Flash memory provides for
maintenance free, non-volatile storage and allows system upgrades.

Introduction Network Protocols
1-3
Network Protocols
Device Servers use IP protocols for network communications. The supported protocols are
ARP, UDP, TCP, ICMP, Telnet, TFTP, DHCP, HTTP, SNMP, and BOOTP. For
connections to the serial port, TCP, UDP, or Telnet protocols are used. Firmware updates
can be performed using TFTP.
The Internet Protocol (IP) defines addressing, routing, and data block handling over the
network. The Transmission Control Protocol (TCP) assures that no data is lost or
duplicated, and that everything sent to the connection arrives correctly at the target.
For typical datagram applications in which devices interact with other devices without
maintaining a point-to-point connection, User Datagram Protocol (UDP) is used.
Packing Algorithms
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 Device Server
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.
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 (e.g., 00-20-4A), identifying the unit as
a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each
Device Server.
Figure 1-1: Sample Ethernet Address
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 Device Server.
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 PBX system.
00-20-4A-14-01-18 or 00:20:4A:14:01:18

3: Getting Started
This chapter covers the required steps to get the Device Server on-line and working.
Consider the following points before logging into and configuring the Device Server:
u The Device Server’s IP address must be configured before a network connection is
available.
u The IP address mustbe within avalid range,unique to your network, and in the same
subnetwork as your PC.
u Only one person at a time may be logged into the Setup (configuration) screen. This
eliminates the possibility of several people simultaneously attempting to configure
the Device Server.
u Network port logins can be disabled. The system manager will not be able to access
the unit if the port is disabled. This port can also be password protected.
u Only one terminal at a time can be connected to a serial port.
Assigning the IP Address
You can several methods to assign an IP address to your Device Server, including:
u DHCP
u AutoIP
u APS Configuration Utility
u ARP
u Direct serial connection
DHCP
IP Address
The Device Server ships with a default setting of 0.0.0.0, which automatically enables
DHCP within the Device Server.
Provided a DHCP server exists on the network, it will supply the Device Server with an IP
address, gateway address, and subnet mask when the Device Server bootsup. (If no DHCP
server exists, the redDiagnostic LED blinks continuously,and the green Status LED blinks
five times.)

Assigning the IP Address Getting Started
3-2
A DHCP-assigned IP address does not appear in the Device Server’s configuration screen
(Setup Menu). You can, however, determine your Device Server’s DHCP-assigned IP
addressin Monitor Mode. When you enter MonitorMode fromthe serial port withnetwork
connection enabled and issue the NC (Network Connection) command., you will see the
Device Server’s IP configuration. (For more information about Monitor Mode, see the
Troubleshooting appendix.)
DHCP Name
A DHCP name is a unique identifier used for managing multiple DHCP hosts on a network.
Your Device Server ships with a default DHCP name of Cxxxxxx, where the xxxxxx is the
last six digits of your Device Server’s MAC address. You can change the DHCP name (up
to 8 characters) from the Server Configuration option on the Setup Menu.
The name can be changed to LTXdd, where 0.0.0.dd is the IP address assigned (dd should
be a number between 1and 99). For example, if the IP address is set to 0.0.0.5, the resulting
DHCP name is LTX05.
Figure 3-1: Server Configuration Option
Note: If you are rolling out a large number of Device Servers and do not
want to track them by their MAC address, change the DHCP name to
LTX##, where ## is the IP address of your Device Server. For
example, if the IP address is 192.169.11.17, then the DHCP name for
the Device Server will be LTX17.
The Device Server’s IP address must be configured before a network connection is
available. If the IP address was not set automatically via DHCP, set it now using one of the
following methods.
Auto IP
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 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices.
The range of Auto IP addresses is not intended to be used over the Internet.
If your Device Server cannot find a DHCP server, and you have not manually assigned an
IP address to it, then it automatically selects an address from the AutoIP reserved range.
Then, your device sends out an (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
Device Server uses it for local subnet communication.
If another device is using the selected IP address, the Device Server selects anotheraddress
fromthe AutoIP range andreboots itself. Afterreboot, the Device Server sends out another
ARP request to see if the selected address is in use, and so on.
Change DHCP device name (LTRX) ? (N) Y
Enter new DHCP device name : LTRXYES

Getting Started Assigning the IP Address
3-3
AutoIP is not intended to replace DHCP. The Device Server will continue to look for a
DHCP server on the network. If it finds a DHCP server, the Device Server 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 Device Server does not attach to the network, but waits and retries.
AutoIP can be disabled by setting the Device Server’s IP address to 0.0.1.0.
APS Configuration Utility
You can manually assign the IP address using the APS Configuration Utility, which you
can install from the APS CD and then select the protocol (firmware) to suit your needs.
1Insert the APS CD into your CD-ROM drive.
2Respond to the installation wizard prompts.
Note: If the CD does not launch automatically, click the Start button on the
Windows Task Bar and select Run.In the Open field, enter your drive
letter, colon, backslash, and setup.exe (e.g., E:\setup.exe). Click OK.
3Click the Start button on the Windows Task Bar, and select Programs-->APS
Config-->APS Config. The Configuration Utility window displays.

Note: If you do not receive Reply received messages, make sure the Device
Server is properly attached to the network and that the IP address
assigned is valid for the particular network segment you are working
with. If you are not sure, check with your Network Administrator.
10 Click the Query Device icon. The Query Device window displays. Confirm
that the IP address is correct.
Figure 3-3: Query Device Window
11 Click the Get Device Information button. Firmware Type displays the protocol
that is currently loaded on the device.
Note: The communications protocol is an integrated part of the Device
Server firmware. When you load the firmware, you are loading the
protocol too. (For that reason, in this manual we use the terms
firmware and protocol interchangeably.)
The unit comes with the Standard Tunneling protocol installed. If your application
requires a different protocol, such as Modbus (Schneider) or DF1 (Allen-Bradley),
follow the steps in Load the Protocol below to install it. Otherwise, proceed to the
Telnet to the Device Server section.

Assigning the IP Address Getting Started
3-6
Load the Protocol (Firmware)
1Click the Load icon. The Load Firmware window displays.
2Click Select FW File. A list of firmware files displays
Figure 3-4: Firmware Files.
3Select the desired protocol and click Open. The selected file displays in the FWFile
field.
4Click Download FW File. The File download successful message displays. Click
OK.
Note: You can use the query tool to confirm that the protocol has been
installed.
Telnet to the Device Server
To configure the Device Server, use the Telnet tool in the APS Configuration Utility. The
tool allows you to establish a terminal session with the Device Server. Within the terminal
session, menus will guide you through the process of configuring the unit.
1Click the Telnet icon and press Enter within 5seconds.
The Configuration Set-Up window for the protocol displays.
2Continue with the configuration procedure for the protocol you installed.
Instructions are in the specific protocol manual on the APS CD.
When you are finished, make sure to save the current configuration and exit. This
configuration is stored in non-volatile memory and is retained even if power is
removed. At this point, the Device Server will reset and restart-- using the
configuration parameters just programmed.

Getting Started Assigning the IP Address
3-7
ARP
ARP can be used from a Windows or Unix host to assign a temporary IP address to the
Device Server. The server sets its IP address from a directed ARP packet and uses it until
it is rebooted. This method only works if your Windows or Unix host are on the same side
of the router.
1On a UNIX host, create an entry in the host’s ARP table using the intended IP
address and the hardware address of the Device Server, which is found on the
product label.
Figure 3-4: ARP on UNIX
For the ARP command to work on Windows 95, the ARP table on the PC musthave
at least one IP address defined other than its own. Type ARP -A at the DOS 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 isat least one additional entry in the
ARP table, use the following command to ARP an IP address to the Device Server:
Figure 3-5: ARP on Windows
2Now open a Telnet connection to port 1. The connection should fail quickly (3
seconds), but the Device Server will temporarily change its IP address to the one
designated in step 1.
Figure 3-6: Telnet to Port 1
3Finally, open a Telnetconnection toport 9999and set all required parameters. Make
sure to enter the information quickly; otherwise you will be timed out and will need
to open a Telnet connection to port 1 again.
Figure 3-7: Telnet to Port 9999
Note: This IP address is temporary and will revert to the default value when
the Device Server’s power is reset. Youmustlog into theDevice Server
and store the changes permanently.
arp -s 191.12.3.77 00:20:4a:xx:xx:xx
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
telnet 191.12.3.77 1
telnet 191.12.3.77 9999

Configuring the Device Server Getting Started
3-8
Direct Serial Connection
1Connect a console terminal or PC running a terminal emulation program to the
Device Server’s first serial port (CH 1). The default serial port settings are 9600
baud, 8 bits, no parity, 1 stop bit, no flow control.
2To enter Setup (configuration) Mode, cycle the Device Server’s power (power off
and back on). After power-up, the self-test beginsand 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 while powering up the Device Server.
3Select 0(Server Configuration) and follow the prompts until you get to IP address.
4Enter the new IP address.
5Select 9to save the configuration and exit Setup Mode. The Device Serverperforms
a power reset.
Note: Every time you exit the configuration menu, the Device Server
performs a power reset even if you did not make any changes.
Configuring the Device Server
Although IAP Device Servers ship with the Standard Tunneling protocol, they also support
other industrial protocols. Refer to the APS CD for instructions on installing another
protocol (User Guide for your Device Server) and configuring the Device Server with that
protocol (appropriate Protocol Manual).
Note: )Only Standard Tunneling communications are simultaneously
supported through both the Device Servers’ serial channels. When
other protocols such as Modbus or DF1 are used, communication is
supported through one serial channel only.

4-1
4: Using the Device Server
Comm Port Redirector
The Lantronix Comm Port Redirector application allows PCs to share modems and other
serial devicesconnectedto a DeviceServer usingWindows-based applications.The Comm
Port Redirector intercepts communications to specified communication ports and sends
them over an IP network connection to the Device Server’s serial port. This enables the PC
to use the Device Server’s serial port as if it were one of the PC’s communication ports.
Using their existing communications software, users can dial out to a remote host through
a modem connected to the Device Server.
Redirector Setup
To set up the Comm Port Redirector software:
1Install the Redirector software from the APS CD. The software and installation
instructions are included on the APS CD.
2In the Redirector’s configuration screen, select Port Setup and add as many
communication ports as you need (for example, one for each Device Server).
3Under each port, selectAdd IP and enter the IP address (Host) of the Device Server
that you want to assign to that port and the TCPPort number (3000 to 3009).
Note: Remember the TCPPort number. You will need it to configure the
Device Server.
4Save the configurations, and if you’ve just installed the Redirector, reboot your PC.
Device Server Configuration
The following procedure should be repeated for each Device Server defined in the
Redirector setup, above.
1Enter the Device Server’s Setup (configuration) Mode (see the protocols manuals on
the APS CD).
2Set the Port Number to a value that is 11000 higher than the TCPPort number
selected in the Redirector setup above (for example, if the TCPPort number was
3005, set the Device Server’s Port Number to 14005).
3Save the configurations and exit Setup Mode.
Note: When using the Redirector, ensure that the Device Server serial port’s
configuration matches the configuration of your serial device.
