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 s olution using TCP/IP and
standard Ethernet networks that is vendor-ind e pen dent.
By encapsulating serial data and transporting it over Ethernet, the Device Server allows
virtual serial links t o be establishe d over Ethernet a nd IP networks. As a result, direct serial
connections can be extended within the plant, throug hout the facility, and across the global
enterprise.
Existing COM-port-based Windows
devices, using Comm Port Re director 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 fiber connectivity for long cable runs or electrically hazardo us
environments.
u
UDS-10-IAP, a compact design Device Server for use in less demanding
environments.

Key Features
IAP Device Servers, adapted to the three factory environments , will unit e any mixture of
equipment from indust rial automation v endors into a sing le reliable pipel ine. 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 P rotocol s Suite (APS) includes protocol s such as DF1 (Rock well
Automation) and Modbus (Schneider Electric). Where the Standard Tu nneli ng p rotoco l 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 po rt, 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
Network Protocols
Device Servers use IP protocols for network communicatio ns. The supported prot ocols 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 withou t
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 algor ith m i s opti mized for app lications in which the Device Serv er
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 f ourth, fifth, and sixt h bytes are u nique numbers assigned to each
Device Server.
Figure 1-1: Sample Ethernet Address
00-20-4A-14-01-18 or 00:20:4A:14:01:18
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 UD P datagram i s defined by a dest ination IP ad dress 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.

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 befor e a network connection is
available.
u
The IP address must be within a valid range, unique to your network, and i n the same
subnetwork as your PC.
u
Only one person at a time may be logged in to the Set up (configu ration) sc reen. 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 t he network, it will su pply the Device S erver with an IP
address, gateway addres s, and subnet mask whe n the Device Server boot s up. (If no DHCP
server exists, the red Di agnostic LED blinks continuously, and the green Status LED bl inks
five times.)
3-1
Assigning the IP Address Getting Started
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
address in Monitor Mod e. When you enter Monit or Mode from the seri al port with network
connection enabled and issue the NC (Network Connection) command., you will see the
Device Server’s IP configuration. (For more infor mat i on abou t 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 Cxxxx xx, where the xxxxxx is the
last six digits of your Device Server’s MAC address . You can change the DHCP nam e (up
to 8 characters) from the Server Configuration option on the Setup Menu.
The name can be changed to LTXdd, where 0.0.0.d d is the IP address assigned (dd s hould
be a number between 1 and 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
Change DHCP device name (LTRX) ? (N) Y
Enter new DHCP device name : LTRXYES
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 ad dr ess i s 1 92. 169 .11.17, then the D HCP n ame fo r
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 canno t find a DHCP s erver, and you have no t man ually ass igned 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 another address
from the AutoIP rang e and reboots it self. After rebo ot, the Device Serv er sends out an other
ARP request to see if the selected address is in use, and so on.
