Console/Serial Switch
Located at the back of the desktop IOLAN models is a switch that controls whether serial port 1 is in
Console or Serial mode.
Look at your model to verify the direction of the ON switch position. ON indicates that serial port 1
is in Console mode; otherwise serial port 1 is in Serial mode.
Console Mode
Console mode is used when you have a direct connection between a serial device (like a terminal or a
PC) and the IOLAN, accessed by the admin user to configure/manage the IOLAN. Console mode
automatically sets serial port settings as:
z Serial Interface to EIA-232
z Speed to 9600
z Flow Control to No
z Bits to 8
z Stop Bits to 1
z Parity to None
Console mode also displays extra system messages.
Serial port 1 will ignore any Serial Port settings when in Console mode, so you need to turn Console
mode off to use serial port 1 in your network.
Getting to Know Your IOLAN
Note:
When the console switch is in the on position, the Power/Ready LED will blink green.
Serial Mode
Serial mode is used when the IOLAN acts as a communications server, or anytime you are not
connecting directly to the IOLAN to configure it. You can connect directly to the IOLAN in Serial
mode, but the IOLAN will not display all the messages/information you will get in Console mode.

Introduction
This chapter provides information about the different methods you can use to configure the IOLAN.
Before you can configure the IOLAN, you must assign an IP address to the IOLAN. See the
Started to find out how to assign an IP address to the IOLAN.
Once an IP address is assigned to the IOLAN, you can use any of the configuration methods to:
z Configure users.
z Configure IOLAN system parameters.
z Configure serial port parameters.
z Configure network parameters.
z Configure time parameters.
z Reboot the IOLAN.
z Manage I/O channels (when applicable).
z View statistics while connected to the IOLAN.

Configuration Methods Overview
Some of the IOLAN configuration methods have the capability of configuring an IP address, which is
the first required configuration step for a new IOLAN. Once the IOLAN has been assigned an IP
address, any of the configuration methods can be used to configure the IOLAN.
Configures an IP Address
Following is a list of methods for setting the IOLAN IP address and a short explanation of when you
would want to use that method:
z Easy Config Wizard—The Easy Config Wizard is available from the CD ROM included with
your IOLAN. You can use the Easy Config Wizard to set the IOLAN’s IP address and configure
serial ports. This configuration method would typically be used when:
z All ports are to have the same configuration.
z Only the most commonly used profiles are required.
z Straightforward application with no advanced functionality required.
z Easy Config is installed on a Windows
z DeviceManager—Use this method when you can connect the IOLAN to the network and access
the IOLAN from a Windows
®
PC. The DeviceManager is a Windows®-based application that
can be used for IOLAN configuration and management. The DeviceManager can be used to
assign an IP address and perform the complete configuration and management of the IOLAN.
z Direct Connection—Use this method when you can connect to the IOLAN from a serial
terminal or from a computer running terminal emulation software over a serial port. Using this
method, you will need to configure and/or manage the IOLAN using either th e Menu or CLI.
z DHCP/BOOTP—Use this method when you have a BOOTP or DHCP server running and you
can connect the IOLAN to your network. The IOLAN will automatically obtain an IP address
from a local network DHCP/BOOTP server when this service is enabled (it is disabled by
default). You can also configure certain IOLAN parameters that will be passed from the
DHCP/BOOTP server to the IOLAN when it boots up. Other configurators such as
DeviceManager, CLI, or Menu can be used to set this option, and obtain the initial IP address.
z ARP-Ping—Use this method when you can connect the IOLAN to the network and want to
assign a temporary IP address to the IOLAN by adding an ARP entry to your PC and then
pinging it.
z IPv6 Network—When the IOLAN is connected to an IPv6 network, its local link address is
determined using stateless auto configuration.
Once an IP address has been assigned to the IOLAN, in most cases, you can continue to use the same
method if it is a configurator or you can switch to any other configuration method.

DHCP/BOOTP
Overview
Several IOLAN parameters can be configured through a DHCP/BOOTP server during the IOLAN
bootup. This is particularly useful for configuring multiple IOLANs.
Not all configuration parameters are supported in the DHCP/BOOTP configuration (see
DHCP/BOOTP Parameters for supported configuration parameters), so you will need to use another
configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.
Features
DHCP/BOOTP supports the following features:
z DHCP/BOOTP can supply the IOLAN’s IP address.
z The DHCP/BOOTP server can configure certain server and user configuration parameters when
the IOLAN is booted.
z The DHCP/BOOTP server can auto-configure the IOLAN with basic setup information (IP
address, subnet/prefix bits, etc.).
z The DHCP/BOOTP server can download a new version of firmware when the IOLAN is
rebooted.
z The DHCP/BOOTP server can download a full configuration file when the IOLAN is rebooted.

parameter, follow the directions in Using a Direct
Using DHCP/BOOTP
To use DHCP/BOOTP, edit the bootp file with IOLAN configurat ion parameters. You can use
DHCP/BOOTP to perform the following actions on a single or multiple IOLANs on bootup:
z auto-configure with minimal information; for example, only an IP address
z auto-configure with basic setup information (IP address, subnet/prefix bits, etc.)
z download a new version of firmware
z download a full configuration file
DHCP/BOOTP is particularly useful for multiple installations: you can do all the IOLANs’
configuration in one DHCP/BOOTP file, rather than configure each IOLAN manually. Another
advantage of DHCP/BOOTP is that you can connect the IOLAN to the network, turn on its power
and let autoconfiguration take place. All the configuration is carried out for you during the
DHCP/BOOTP process.
Configuration Methods 42
Page 43
DHCP/BOOTP Parameters
The following parameters can be set in the DHCP/BOOTP bootp file:
z SW_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the
firmware update.
z CONFIG_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name
of the configuration file. Note: these parameters include clear text user passwords.
z GUI_ACCESS—Access to the IOLAN from the HTTP WebManager. Values are on or off.
z SECURITY—Restricts IOLAN access to devices listed in the IOLAN’s host table. Values are
yes or no.
z TFTP_RETRY—The number of TFTP attempts before aborting. This is a numeric value, for
example, 5.
z TFTP_TMOUT—The time, in seconds, before retrying a TFTP download/upload. This is a
numeric value, for example, 3.
z CUSTOM_LANG—The full path, pre-fixed by a hostname/IP address (IPv4 or IPv6), and file
name of a translated language file. For example,
192.101.34.211 /accounting/Iolan_ds_german.txt.
z EXTRA_TERM1—(EXTRA_TERM2, EXTRA_TERM3) The full path, pre-fixed by a
hostname/IP address (IPv4 or IPv6), and file name of a termcap file for a specific terminal type.

SNMP
Overview
The IOLAN supports configuration and management through SNMP. SNMP Management tools
(SNMP client/MIB browser software) can be used to set IOLAN configuration parameters and/or
view IOLAN statistics.
Before you can configure/manage the IOLAN using SNMP, although you need to set the IOLAN IP
address and configure a read-write user for SNMP version 3 or a community for SNMP version 1 or
2. You can use DeviceManager, CLI, or the Menu to set the IP address and user/community (don’t
forget to reboot the IOLAN before connecting with the SNMP manager to make your changes take
effect).
Access Platforms
You can access the IOLAN SNMP MIB from any system that runs your SNMP client/MIB browser
software.
Features
SNMP supports the following features:
z You can configure SNMP traps.
z Since not all versions of SNMP support secure communication, password parameters must be set
using another configuration method.
SNMP
Connecting to the IOLAN Using SNMP
Before you can connect to the IOLAN through an SNMP Management tool or MIB browser, you
need to set the following components through another configuration method.
1. Configure a known IP address on the IOLAN.
2. Configure a read-write user for SNMP version 3 or a community for SNMP version 1 or 2 on the
IOLAN.
3. Reboot the IOLAN to make sure the changes take effect.
To connect to the IOLAN through an SNMP Management tool or MIB browser, do the following:
1. Load the perle-ds.MIB file from the IOLAN CD-ROM or Perle website into your SNMP
manager (this MIB works for all DS1 and TS2 models).
Note:
2. Verify that the read-write user for SNMP version 3 or a commu nit y for SNMP version 1 or 2
match the configuration on the IOLAN.
3. Type in the IOLAN’s IP address and connect to the IOLAN.
You are now ready to start configuring the IOLAN using SNMP.
You need to have the following MIBs installed in yo ur SNMP manager (these are
usually part of the standard SNMP client/MIB browser):
z SNMPv2-SMI
z SNMPv2-TC

Introduction
There are several different configuration methods available to configure the IOLAN Configuration
Methods Overview for more information. This chapter describes the three main minimal
configuration requirements for the IOLAN through either Easy Config Wizard (cannot configure
users using this method), DeviceManager, or WebManager:
1. Setting up the network—This minimally consists of configuring an IP address or enabli n g
DHCP/BOOTP. Once the IOLAN has an IP address, you can use any configuration method.
2. Setting up the serial ports—You will want to select the serial port profile that matches the serial
port requirement/scenario for your serial device.
3. Setting up users—This is an optional step, which is only required when your implementation
requires users to access the IOLAN.
Easy Configuration Wizard
The Easy Config Wizard quickly sets up the IOLAN’s network configuration and all serial ports to
one of the following:
z Console Management—Allows users on the network to connect to a serial device that is
connected to a serial port on the IOLAN.
IOLAN DS1/TS2 User’s Guide, Version 4.5 46
Page 47
z TruePort (Virtual COM Port)—Allows a networked system to communicate with your serial
device through a virtual COM or TTY port, using the Perle TruePort software.
z TCP Sockets (Raw TCP)—Allows hosts on the network to communicate with a serial device
that requires raw data throughput (such as a printer or card reader) connected to the IOLAN
serial port.
z Terminal—Allows a terminal device to connect to a specified host on the network through a
serial port on the IOLAN.
z Printer—(SDS/STS/SCS only) Allows hosts on the network to talk to a printer using LPD
connected to the IOLAN.
z Serial Tunneling—Allows IOLAN s on the network to establish a virtual link between their
serial ports. Typically, one IOLAN’s serial port is configured as a Tunnel Server and the other
IOLAN’s serial port is configured as a Tunnel Client.
Setting Up the Network
The most important part of setting up the network is assigning an IP address to the IOLAN, whether
this is a static IP address or enabling a DHCP/BOOTP-assigned IP address. You should also assign a
name to the IOLAN, to make it easier to recognize. This section deals primarily with setting the IP
address.
Setting Up the Network
Using DeviceManager
To use the DeviceManager, you must first install it on a Windows® operating system. The
DeviceManager is able to automatically discover all IOLANs on your local network, even if they
have not yet been assigned an IP address. If routers on the network have been setup to propagate
multicasts, DeviceManager will also be able to discover IOLANs in other networks. The
DeviceManager installation wizard can be found on the CD-ROM included in the IOLAN package.
1. Connect the IOLAN to the network.
2. Power on the IOLAN.
3. From the CD-ROM that was included in the IOLAN packaging, select the DeviceManager link.
4. Click on the link under Location and click Open to automatically start the DeviceManager
installation.
5. Install the DeviceManager by following the installation wizard. On the last window, check the
Yes, I want to launch DeviceManager now. box and click the Finish button.
6. When you launch the DeviceManager, it will automatically scan the local network and display
any IOLANs that it can find.
7. Any IOLAN that does not have an IP address will be displayed as Not Configured, with the
Model and MAC Address to identify the IOLAN. Highlight the IOLAN that you want to assign
an IP address to and click the
8. Choose the method you want to use to assign an IP address to the IOLAN:
z Type in the IP address that you want to assign to this IOLAN.
z Enable the Have the IOLAN automatically get a temporary IP address option. This will

Using a Direct Serial Connection to Enable BOOTP/DHCP
If you are using BOOTP, you need to add an entry in the BOOTP server for the IOLAN that
associates the MAC address (found on the back of the IOLAN) and the IP address that you want to
assign to the IOLAN. After you have made the MAC address/IP address association for BOOTP, use
the following directions for BOOTP or DHCP.
You can connect to the IOLAN using a PC with a terminal emulation package, such as
HyperTerminal or a dumb terminal.
1. Connect the IOLAN to your PC or dumb terminal. Make sure the DIP switch is in Console mode
(desktop models, this sets the IOLAN serial port to EIA-232). When connecting a terminal or PC
directly (without modems), the EIA-232 signals need to be crossed over (‘null modem’ cable).
See
EIA-232 Cabling Diagrams for cabling diagrams.
2. Using a PC emulation application, such as HyperTerminal, or from a dumb terminal, set the Port

If for some reason it cannot obtain an IP address from your DHCP/BOOTP server, you will have to
either reconnect to the IOLAN on the console port and reboot it or push the Reset to Factory button to
access the IOLAN.
You are now ready to configure the IOLAN. See Configuration Methods Overview for information
on the different IOLAN configuration methods.

Using ARP-Ping
You can use the ARP-Ping (Address Resolution Protocol) method to temporarily assign an IP address
and connect to your IOLAN to assign a permanent IP address. To use ARP-Ping to temporarily assign
an IP address:
1. From a local UNIX/Linux host, type the following at the system command shell prompt:
arp -s a.b.c.d aa:bb:cc:dd:ee:ff
On a Windows® 2000 or newer system, type the following at the command prompt:
arp -s a.b.c.d aa-bb-cc-dd-ee-ff
(where a.b.c.d is the IPv4 address you want to temporarily assign to the IOLAN, and
aa:bb:cc:dd:ee:ff is the Ethernet (MAC) address of IOLAN (found on the back of the unit).
2. Whether you use UNIX or Windows®, you are now ready to ping to the IOLAN. Here is a UNIX
example of the sequence to use:
arp -s 192.168.209.8 00:80:d4:00:33:4e
ping 192.168.209.8
From the ping command issued in step 2, the IOLAN will pickup and use the IP address entered into
the ARP table in step 1. You are now ready to configure the IOLAN. See
Overview for information on the different IOLAN configuration methods.

Setting Up the Serial Port(s)
The DeviceManager and WebManager have the following serial port profiles that will simplify serial
port setup:
Setting Up the Serial Port(s)
z Console Management—The Console Management profile configures a serial port to provide
network access to a console or administrative port. This profile sets up a serial port to support a
TCP socket that listens for a Teln et connection from the network.
z TruePort—The TruePort profile configures a serial port to connect network servers or
workstations running the TruePort software to a serial device as a virtual COM port. This profile
is ideal for connecting multiple serial ports to a network system or server.
z TCP Sockets—The TCP Sockets profile configures a serial port to allow a serial device to
communicate over a TCP network. The TCP connection can be configured to be initiated from
the network, a serial device connected to the serial port, or both. This is sometimes referred to as
a raw connection or a TCP raw connection.
z UDP Sockets—The UDP Sockets profile configures a serial port to allow communication
between the network and serial devices connected to the IOLAN using the UDP protocol.
z Terminal—The Terminal profile configures a serial port to allow network access from a terminal
connected to the IOLAN’s serial port. This profile is used to access predefined hosts on the
network from the terminal.
z Serial Tunneling—The Serial Tunneling profile configures a serial port to establish a virtual link
over the network to a serial port on another IOLAN. Both IOLAN serial ports must be
configured for Serial Tunneling (typically one serial port is configured as a Tunnel Server and
the other serial port as a Tunnel Client).
z Virtual Modem—The Virtual Modem (Vmodem) profi le configures a serial port to simulate a
modem. When the serial device connected to the IOLAN initiates a modem connection, the
IOLAN starts up a TCP connection to another IOLAN configured with a Virtual Modem serial
port or to a host running a TCP application.
Getting Started 51
Page 52
Setting Up the Serial Port(s)
z Control Signal I/O—The Control Signal I/O profile enables the use of the EIA-232 serial port
signal pins to be used as assigned Digital Inputs or Digital Outputs.
z Modbus Gateway—The Modbus Gateway profile configures a serial port to act as a Modbus
Master Gateway or a Modbus Slave Gateway.
z Custom Application/Plugin—The Custom Application/Plugin profile configures a serial port to
run a custom application or IOLAN plugin. After you download the custom application files and
specify the application name and any parameters you want to pass to it, the IOLAN will execute
the application when the serial port is started.
Each serial port profile contains all the parameters that are required to completely configure the serial
port scenario represented by the profile.
To select a serial port profile in the DeviceManager, connect through the DeviceManager to the
IOLAN you are configuring and select
serial port you want to configure and then click

Introduction
The DeviceManager and WebManager IOLAN managers have been designed to be very similar to
use. DeviceManager is a Windows
application. Both options use the IOLAN’s IP address to access the IOLAN; the DeviceManager can
be used to assign an IP address to a new IOLAN and the WebManager requires that the IOLAN
already have an IP address before it can be used to configure the IOLAN.
When using W ebManager, you are required to click the Apply button each time you make a change to
a configuration window/tab. In DeviceManager, you must download your configuration changes to
the IOLAN either periodically or after you are done with the configuration changes. From both
managers you must reboot the IOLAN in order for you configuration changes to take effect.

Common Tabs
Overview
There are several functions that are common to more than one profile. These functions are:
z Hardware—Configure the physical serial line parameters. See Hardware Tab Field
Descriptions .
z Packet Forwarding—Configure data packet parameters. See Packet Forwarding Tab Field
Descriptions .
Hardware Tab Field Descriptions
The Hardware tab configures all the serial port hardware connection information.
Serial Port Profiles
Configure the following parameters:
Serial Interface Specifies the type of serial line that is being used with the IOLAN.
Data Options: EIA-232, EIA-422, or EIA-485. TS2 models support only EIA-
232.
Default: EIA-232
Speed Specifies the baud rate of the serial line; keep in mind that speed is affected by
the length of the cable. You can also specify a custom baud rate. When you
enter a custom baud rate, the IOLAN will calculate the closest baud rate
available to the hardware. The exact baud rate calculated can be viewed in the
Serial Ports statistics.
Range: 50-230400, custom supports 50-1843200
Default: 9600
Data Bits Specifies the number of bits in a transmitted character.
Default: 8

Monitor DSR Specifies whether the EIA-232 signal DSR (Data Set Ready) should be
monitored. This is used with modems or any device that sends a DSR signal.
When it is monitored and the IOLAN detects a DSR signal, the line profile is
started. If both
Monitor DCD and Monitor DSR are enabled, both signals must
be detected before the line profile is started.
Default: Disabled
Monitor DCD Specifies whether the EIA-232 signal DCD (Data Carrier Detect) should be
monitored. This is used with modems or any other device that sends a DCD
signal. When it is monitored and the IOLAN detects a DCD signal, the line
profile is started. If both
Monitor DCD and Monitor DSR are enabled, both
signals must be detected before the line profile is started.
Default: Disabled
Enable Echo
Suppression
This parameter applies only to EIA-485 Half Duplex mode. All characters will
be echoed to the user and transmitted across the serial ports. Some EIA-485
applications require local echo to be enabled in order to monitor the loopback
data to determine that line contention has occurred. If your application cannot
handle loopback data, echo suppression should be enabled.
Default: Disabled

When enabled, specifies the character that when received will define when the
packet is ready for transmission. The actual transmission of the packet is based
on the Trigger Forwarding Rule.
Range: Hex 0-FF
Default: 0
Enable Trigger2
Character
When enabled, creates a sequence of characters that must be received to
specify when the packet is ready for transmission (if the End Trigger1
character is not immediately followed by the End Trigger2 character, the
IOLAN waits for another End Trigger1 character to start the End Trigger1/End
Trigger2 character sequence). The actual transmission of the packet is based on
the Trigger Forwarding Rule.
Range: Hex 0-FF
Default: 0
Frame Definition When enabled, this group of parameters allows you to control the frame that is
transmitted by defining the start and end of frame character(s). If the internal
buffer (1024 bytes) is full before the EOF character(s) are received, the packet
will be transmitted and the EOF character(s) search will continue.
Default: Disabled
SOF1 Character When enabled, the Start of Frame character defines the first character of the
frame, any character(s) received before the Start of Frame character is ignored.
Range: Hex 0-FF
Default: 0
SOF2 Character When enabled, creates a sequence of characters that must be received to create
the start of the frame (if the SOF1 character is not immediately followed by the
SOF2 character, the IOLAN waits for another SOF1 character to start the
SOF1/SOF2 character sequence).
Range: Hex 0-FF

Break Handling Specifies how a break is interpreted.
Data Range:
z None—The IOLAN ignores the break key completely and it is not passed
through to the host.
z Local—The IOLAN deals with the break locally. If the user is in a
session, the break key has the same effect as a hot key.
z Remote—When the break key is pressed, the IOLAN translates this into a
telnet break signal which it sends to the host machine.
z Break Interrupt—On some systems such as SunOS, XENIX, and AIX, a
break received from the peripheral is not passed to the client properly. If
the client wishes to make the break act like an interrupt key (for example,
when the stty options
-ignbrk and brkintr are set).
Default: None
Session Strings Controls the sending of ASCII strings to serial devices at session start and
session termination as follows;
z Send at Start—If configured, this string will be sent to the serial device
on power-up of the IOLAN or when a kill line command is issued on this
serial port. If the "monitor DSR" or "monitor DCD" options are set the
string will also be sent when the monitored signal is raised.
z Range: 0-127 alpha-numeric characters. Non printable ascii characters
must be entered in this format <027>. The decimal numbers within the
brackets must be 3 digits long (example 003 not 3).
z Send at End—If configured, this string will be sent to the serial device
when the TCP session on the LAN is terminated. If multihost is
configured, this string will only be sent to the serial device when the
profile is configured as a listen mode connection and after all multihost
connections are terminated.
Range: 0-127 alpha-numeric characters. Non printable ascii characters
must be entered in this format <027>. The decimal numbers within the
brackets must be 3 digits long (example 003 not 3).
z Delay after Send—If configured, a delay time is sent to the device. This
delay can be used to provide the serial device with time to process the
string before the session is initiated.
Range: 0-65535 ms
Default: 10 ms

Tr uePort Profile
Overview
TruePort is COM Port redirector that is supplied with the IOLAN. TruePort can be installed as a
client on a Workstation or Server and supports a variety of operating systems. It, in conjunction with
the IOLAN, emulates a local serial port (COM port), to the application, to provide connectivity to a
remote serial device over the network. The TruePort profile operates in conjunction with the TruePort
software.
Serial Port Profiles

Range: 1-99
Default: 45 seconds
a remote modem.
Range: 0-99
Default: 2
Functionality
TruePort is a COM port redirector utility for the IOLAN. It can be run in two modes (these modes
will be set on the client software when it is configured):
z TruePort Full mode—This mode allows complete device control and operates as if the device
was directly connected to the Workstation/Server’s local serial port. It provides a complete COM
port interface between the attached serial device and the network. All serial controls, baud rate
control, etc., are sent to the IOLAN and replicated on its associated serial port.
z TruePort Lite mode—This mode provides a simple raw data interface between the application
and the remote serial port. Although the port will still operate as a COM port, control signals are
ignored. In this mode, the serial communications parameters must be configured on the IOLAN.
See the TruePort User’s Guide for more details about the TruePort client software.
General Tab Field Descriptions
The TruePort General tab determines how the TruePort connection is initiated and then sets up the
appropriate connection parameters.

TCP Sockets Profile
Overview
The TCP Socket profile allows for a serial device to communicate over a TCP network. The TCP
connection can be initiated from a host on the network and/or a serial device. This is typically used
with an application on a Wo rkstation or Server that communicates to a device using a specific TCP
socket. This is often referred to as a RAW connection.
Functionality
The TCP Sockets profile permits a raw connection to be established in either direction, meaning that
the connection can be initiated by either the Workstation/Server or the IOLAN.

UDP Sockets Profile
Overview
The UDP profile configures a serial port to send or receive data to/from the LAN using the UDP
protocol.
Functionality
You can use UDP profile in the following two basic modes. The first is to send data coming from the
serial device to one or more UDP listeners on the LAN. The second is to accept UDP datagrams
coming from one or more UDP senders on the LAN and forward this data to the serial device. You
can also configure a combination of both which will allow you to send and receive UDP data to/from
the LAN.
Serial Port Profiles
Sample UDP Sockets configuration screen
Four individual entries are provided to allow you greater flexibility to specify how data will be
forwarded to/from the serial device. All four entries support the same configuration parameters. You
can configure one or more of the entries as needed.
The first thing you need to configure for an entry is the “Direction” of the data flow. The following
options are available;
z Disabled - UDP service not enabled.
z LAN to Serial - This setting will allow UDP data to be received from one or more hosts on the
LAN and forwarded to the serial device attached to this serial port.
z Serial to LAN - This setting will allow data originating from the serial device attached to this
serial port to be sent to one or more hosts on the LAN using UDP datagrams.
86
Page 87
Serial Port Profiles
z Both - Allows for data to flow from the serial device to the LAN and from the LAN to the serial
device.
The role of each of the configurable parameters in an entry depends on the “Direction” selected.
When the direction is "LAN to Serial" the role of the additional parameters is as follow;
z Start IP Address - This is the IP address of the host from which the UDP data will originate. If
the data will originate from a number of hosts, this becomes the starting IP address of a range.
z End IP Address - If you wish to receive data only from the single host defined by "Start IP
address", leave this entry as is (0.0.0.0). If you wish to accept data from a number of hosts, this
address will represent the upper end of a range starting from "Start IP Address". Only data
originating from this range will be forwarded to the serial port.
z UDP port - This is the UPD port from which the data will originate. There are three options for
this parameter.
z Auto Learn - The first UDP message received will be used to define which UDP port we
are going to accept UDP data from. Once learned, only data from this UDP port will be
accepted. The data must also originate from a host which is in the IP range defined for this
entry.
z Any Port - Any UDP port will be accepted as long as the data originates from a host in the
IP range defined for this entry.
z Port - Only data originating from the UDP port configured here as well as originating from
a host in the IP range defined for this entry will be accepted.
When the direction is "Serial to LAN" the role of the additional parameters is as follow;
z Start IP Address - This is the IP address of the host to which the serial data will be sent using
UDP datagrams. If the serial data is to be sent to more than one host, this becomes the starting IP
address of a range.
z End IP Address - If you wish to send serial data to a single host, leave this entry as is (0.0.0.0).
If you wish to send the serial data to a number of hosts, this address will represent the upper end
of a range starting from "Start IP Address".
z UDP port - This is the UPD port to which the serial data will be forwarded. For a direction of
"Serial to LAN", you must specify the port to be used.
When the direction is "Both" the role of the additional parameters is as follow;
z Start IP Address - This is the IP address of the host to which the serial data will be sent using
UDP datagrams. It is also the IP address of the host from which UDP data coming from the LAN
will be accepted from. If the data is to be sent to or received from more than one host, this
becomes the starting IP address of a range.
z End IP Address - If you wish to send serial data to a single host and only receive data from the
single UDP host, leave this entry as is (0.0.0.0). If the data is to be sent to or received from more
than one host, this address will represent the upper end of a range starting from "Start IP
Address". Only data originating from this range will be forwarded to the serial port.
z UDP Port - This is the UPD port to which the serial data will be forwarded as well as the UPD
port from which data originating on the LAN will be accepted from. For a direction of "Both",
there are two valid option for the UDP Port as follows;
z Auto Learn - The first UDP message received will be used to define which port we are
going to accept UDP data from. Once learned, only data from this UDP port will be accepted
and serial data being forwarded to the LAN will be sent to this UDP port. Until the port is
learned, data from the serial port intended to be sent to the LAN will be discarded.
87
Page 88
Serial Port Profiles
z Port - Serial data being forwarded to the LAN from the serial device will sent to this UDP
port. Only data originating from the UDP port configured here (as well as originating from a
host in the IP range defined for this entry) will be forwarded to the serial device.
Special values for "Start IP address"
z 0.0.0.0 - This is the "auto learn IP address” value which is valid only in conjunction with the
"LAN to Serial" setting. The first UDP packet received for this serial port will set the IP address
from which we will accept future UDP packets to be forwarded to the serial port. For this setting,
leave the "End IP Address" as 0.0.0.0.
z 255.255.255.255 - This selection is only valid in conjunction with the "LAN to Serial" setting. It
will accept all UDP packets received for this serial port regardless of the originating IP address.
For this setting, leave the "End IP Address" as 0.0.0.0.
z Subnet directed broadcast - You can use the “Start IP Address” field to enter a subnet directed
broadcast address. This is done by specifying the subnet address with the host portion filled with
1s. For example, if you are on the subnet 172.16.x.x with a subnet mask of 255.255.254.0 than
you would specify an IP address of 172.16.1.255 (all ones for host portion). For this setting,
leave the "End IP Address" as 0.0.0.0. For any “LAN to Serial” ranges you have defined for this
serial port, you must ensure that IP address of this IOLAN is not included in the range. If your IP
address is within the range, you will receive the data you send via the subnet directed broadcasts
as data coming in from the LAN.
An example UDP configuration is described based on the following window.
The UDP configuration window, taken from the DeviceManager, is configured to:
z UDP Entry 1
All UDP data received from hosts that have an IP address that falls within the range of
172.16.1.25 to 172.16.1.50 and source UDP Port of 33010 will be sent to the serial device.
The IOLAN will not send any data received on its serial port to the host range defined by this
entry.
z UDP Entry 2
All hosts that have an IP Address that falls within the range of 172.16.1.75 to 172.16.1.80

Virtual Modem Profile
Overview
Virtual Mo dem (Vmodem) is a feature of the IOLAN that provides a modem interface to a serial

modem would. This feature is typically used when you are replacing dial-up modems with the
IOLAN in order to provide Ethernet network connectivity.

The serial port will behave in exactly the same fashion as it would if it were connected to a modem.
Using AT commands, it can configure the modem and the issue a dial-out request (ATTD). The
IOLAN will then translate the dial request into a TCP connection and data will be begin to flow in
both directions. The connection can be terminated by ’hanging’ up the phone line.
You can also manually start a connection by typing ATD<ip_address>,<port_number> and end
the connection by typing
address of the receiver. For example,
ATD12303402304310001, without any punctuation (although you do need to add zeros where there
are not three digits presents, so that the IP address is 12 digits long).
Serial Port Profiles
+++ATH. The ip_address can be in IPv4 or IPv6 formats and is the IP
ATD123.34.23.43,10001 or you can use

Configure the following parameters:
Serial Port Profiles
Listen on TCP Port The IOLAN TCP port that the IOLAN will listen on.
Default: 10000 + serial port number (for example, serial port 12 defaults to
10012)
Connect

Status As
When enabled, automatically establishes the virtual modem connection when
the serial port becomes active.
Default: Enabled
Default: 0 (zero)
When enabled, the virtual modem requires an AT command before it
establishes a connection. Specify this option when your modem application
sends a phone number or other AT command to a modem. The serial device
can supply an IP address directly or it can provide a phone number that will be
translated into an IP address by the IOLAN using the mapping table.
Default: Disabled
When your modem application provides a phone number in an AT com mand
string, you can map that phone number to the destination host.
See Phone Number to Host Mapping for information about the window that
appears when you click this button.
When enabled, the connection success/failure indication strings are sent to the
connected device, otherwise these indications are suppressed. This option also
determines the format of the connection status results that are generated by the
virtual modem.
Default: Enabled
Verbose String When enabled, the connection status is sent by text strings to the connected
device.
Default: Disabled
