Introduction Chapter 1

About the IOLAN

The IOLAN is an Ethernet communications/terminal server that allows serial devices to be connected directly to LANs. The IOLAN can connect to a wide range of devices including:

z T erminals for multi-user UNIX systems z Data acquisition equipment (manufacturing, laboratory, scanners, etc.) z Retail point-of-sale equipment (bar coding, registers, etc.) z PCs using terminal emulation z Modems for remote access and Internet access z ISDN adapters for branch remote access and Internet access z All types of serial printers

The performance and flexibility of the IOLAN allows you to use a wide range of high speed devices in complex application environments. The IOLAN products will work in any server environment running TCP/UDP/IP.

IOLAN Family Models

The IOLAN comes in several different models to meet your network needs:

z DS—Offered as a 1-port unit (DB25M, DB25F, RJ45, and DB9M interfaces available), this

model provides general IOLAN functionality and supports software configurable serial interface protocols EIA-232/422/485.

z TS—This model is available with two serial ports (RJ45 only) and supports EIA-232 only. The

TS model is similar to the DS model supporting only general IOLAN functionality.

z SDS—This model is available in both desktop and rack mount configurations. Both models

support software configurable serial interface protocols EIA-232/422/485. The SDS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.

z STS—This model comes in one desktop model and several rack mount configurations. All

models support EIA-232 only. The STS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.

z SCS—This model comes in several rack mount configurations. All models support EIA-232

only and have an internal PCI card interface. The SCS model has the advanced secure IOLAN feature set in addition to the general IOLAN functionality.

See Hardware on page 20 for information about the hardware specifications for your IOLAN model. See Software on page 21 for a list of the basic and advanced software features.

Getting to Know Your IOLAN

This section describes the hardware components found on your IOLAN unit.

Overview

All IOLANs have the same basic hardware components to allow you to connect to serial devices, connect to the network, monitor LAN and serial activity, and manage the unit. Below is a list of these components:

z Serial Port(s)—Connector(s) that will be used to connect to a serial device. z Activity—This LED flashes to indicate LAN activity. z Link10/100—This LED indicates the Ethernet connection speed for desktop models:

– Green—10 Mbits – Yellow—100 Mbits –Off—no LAN connection

z Power/Ready—This LED can cycle through several colors (yellow, green, red) during a boot

process, but should complete with a green light. If the LED is green after power up but continues to cycle on and off (flashes green), this indicates that the console switch is in the on position. You can learn more about the Power/Ready LED in

z External Power Supply—This is an external AC power supply. z Console/Serial Switch—This switch determines whether serial port 1 functions as a serial port

or a console port. If you have an I/O model, you will see two console switches. Console/Serial Switch 1 is used to determine the console/serial setting for Port 1 and the Console/Serial Switch 2 is not used.

z Reset—The inset RESET button will reboot the IOLAN if pushed in and released quickly. It will

reset the IOLAN to factory defaults if pushed in and held for more than three seconds.

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 LED will cycle on and off (flashes 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.

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 Confi g 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-based PC with local network access to the IOLAN.

z DeviceManager—Use this method when you can connect the IOLAN to the network and access

the IOLAN from a Windows 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 the 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 specifying an ARP entry from 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.

Unique Features

The CLI supports the following unique features:

z You can access the IOLAN from any application that supports Telnet. z Ability to clear the ARP table (cache).

Command Line Interface

Connecting to the IOLAN Using the CLI

There are two ways you can access the IOLAN, through the network (Ethernet connection) or through the serial connection. If you are accessing the IOLAN through the network, the IOLAN must already have a known IP address configured; see

Address on page 47 getting started for information on configuring an IP address.

Through the Network

To connect to the IOLAN through the network to configure/manage it using the CLI, do the following:

1. Start a Telnet session to the IOLAN’s IP address; for example:

telnet 10.10.201.100

2. You will get a Login: prompt. You can login as the admin user or as a user with Admin Level

rights. If the login is successful, you will get a prompt that displays the IOLAN model and

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 on page 41 for supported configuration parameters), so you will need to

use another configuration method, such as DeviceManager, WebManager or CLI, to complete the configuration.

Unique Features

DHCP/BOOTP supports the following unique features:

z DHCP/BOOTP can supply the IOLAN’s IP address. z The DHCP/BOOTP server can configure certain server and user configuration parameter s wh en

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.

Connecting to the IOLAN Using DHCP/BOOTP

The IOLAN will automatically request an IP address from the DCHP/BOOTP server when the

parameter, follow the directions in Using a Direct

Using DHCP/BOOTP

To use DHCP/BOOTP, edit the bootp file with IOLAN configuration param eters. 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.

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, altho ugh yo u 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.

Unique Features

SNMP supports the following unique 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.

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 community 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.

Introduction

There are several different configuration methods available to configure the IOLAN (see Chapter 3,

Configuration Methods on page 29 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 minimal ly consists of configuring an IP address or enabling

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 3.4 45

Page 46

Setting Up the Network

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 IOLANs on the netwo rk to establish a virtual link bet ween 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 Tu nnel 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 the IOLAN, to make it easier to recognize. This section deals primarily with setting the IP address.

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

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

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® 98 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

Methods on page 29 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:

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 Telnet 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) profile 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.

50 IOLAN DS1/TS2 User’s Guide, Version 3.4

Page 51

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

Using DeviceManager

Introduction

The DeviceManager and WebManager IOLAN managers have been designed to be very similar to use. DeviceManager is a Windows-based application and WebManager is a browser-based 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 WebManager, 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 on page 70.

z Packet Forwarding—Configure data packet parameters. See Packet Forwarding Tab Field

Descriptions on page 72.

Hardware Tab Field Descriptions

The Hardware tab configures all the serial port hardware connection information.

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

Parity Specifies the type of parity being used for the data communication on the serial

port. If you want to force a parity type, you can specify

Mark for 1or Space for

Data Options: Even, Odd, Mark, Space, None Default: None

Stop Bits Specifies the number of stop bits that follow a byte.

Data Options: 1,1.5, 2 Default: 1

Duplex Used with a EIA-485 serial interface, specify whether the serial port is Full

Duplex

(communication both ways at the same time) or Half Duplex

(communication in one direction at a time).

Default: Full

TX Driver Control Used with a EIA-485 serial interface, if your application supports RTS

(Request To Send), select this option. Otherwise, select

Auto.

Default: Auto

Flow Control Defines whether the data flow is handled by the software (Soft), hardware

(

Hard), Both, or None.

Data Options: Soft, Hard, Both, None Default: None

Enable Inbound Flow Control

Enable Outbound Flow Control

Determines if input flow control is to be used. Default: Enabled

Determines if output flow control is to be used.

Default: Enabled

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

Serial Port Profiles

Packet Forwarding Tab Field Descriptions

The Packet Forwarding tab can be used to control/define how and when data packets are sent from the IOLAN.

Configure the following parameters:

Minimize Latency This option ensures that all application data is immediately forwarded to the

serial device and that every character received from the device is immediately sent on the network. Select this option for timing-sensitive applications.

Default: Enabled

Optimize Network Throughput

Prevent Message Fragmentation

Delay Between Messages

Custom Packet Forwarding

This option provides optimal network usage while ensuring that the application performance is not compromised. Select this option when you want to minimize overall packet count, such as when the connection is over a WAN.

Default: Disabled This option detects the message, packet, or data blocking characteristics of the

serial data and preserves it throughout the communication. Select this option for message-based applications or serial devices that are sensitive to inter-character delays within these messages.

Default: Disabled The minimum time, in milliseconds, between messages that must pass before

the data is forwarded by the IOLAN.

Range: 0-65535 Default: 250 ms

This option allows you to define the packet forwarding rules based on the packet definition or the frame definition.

Default: Disabled

72 IOLAN DS1/TS2 User’s Guide, Version 3.4

Page 73

Serial Port Profiles

Packet Definition When enabled, this group of parameters allows you to set a variety of packet

definition options. The first criteria that is met causes the packet to be transmitted. For example, if you set a

Packet Size of 100 bytes, whichever criteria is met first is what will cause the

Force Transmit Timer of 1000 ms and a

packet to be transmitted.

Default: Enabled

Packet Size The number of bytes that must be received from the serial port before the

packet is transmitted to the network. A value of zero (0) ignores this parameter.

Range: 0-1024 bytes Default: 0

Idle Time The amount of time, in milliseconds, that must elapse between characters

before the packet is transmitted to the network. A value of zero (0) ignores this parameter.

Range: 0-65535 ms Default: 0

Enable Trigger1 Character

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 Default: 0

Transmit SOF Character(s)

When enabled, the SOF1 or SOF1/SOF2 characters will be transmitted with the frame. If not enabled, the SOF1 or SOF1/SOF2 characters will be stripped from the transmission.

Default: Disabled

Page 74

Serial Port Profiles

EOF1 Character Specifies the End of Frame character, which defines when the frame is ready to

be transmitted. The actual transmission of the frame is based on the Trigger

Forwarding Rule.

Range: Hex 0-FF

Default: 0 EOF2 Character When enabled, creates a sequence of characters that must be received to define

the end of the frame (if the EOF1 character is not immediately followed by the

EOF2 character, the IOLAN waits for another EOF1 character to start the

EOF1/EOF2 character sequence), which defines when the frame is ready to be

transmitted. The actual transmission of the frame is based on the Trigger

Forwarding Rule.

Range: Hex 0-FF

Default: 0 Trigger

Forwarding Rule

Determines what is included in the Frame (based on the EOF1 or EOF1/EOF2)

or Packet (based on Trigger1 or Trigger1/Trigger2). Choose one of the

following options:

z Strip-Trigger—Strips out the EOF1, EOF1/EOF2, Trigger1, or

Trigger1/Trigger2, depending on your settings.

z Trigger—Includes the EOF1, EOF1/EOF2, Trigger1, or

Trigger1/Trigger2, depending on your settings.

z Trigger+1—Includes the EOF1, EOF1/EOF2, Trigger1, or

Trigger1/Trigger2, depending on your settings, plus the first byte that follows the trigger.

z Trigger+2—Includes the EOF1, EOF1/EOF2, Trigger1, or

Trigger1/Trigger2, depending on your settings, plus the next two bytes received after the trigger.

Default: Trigger

Console Management Profile

Overview

The Console Management profile provides access through the network to a console or administrative port of a server or router attached to the IOLAN’s serial port. This profile configures the IOLAN’s serial port to set up a TCP socket that will listen for a Telnet connection from the network.

Functionality

Use the Console Management profile when you are configuring users who need to access a serial console port from the network.

thus either ensuring the connection stays active OR causing a dropped

connection condition to be recognized.

This parameter needs to be used in conjunction with

Status Interval

parameter found in the Serial, Advanced, Advanced Settings

Monitor Connection

tab. The interval determines how long the IOLAN will wait during inactivity

before "testing" the connection. It should be noted that if a network connection

is accidentally dropped, it can take as long as the specified interval before

anyone can reconnect to the serial port.

Default: Disabled Enable Message of

the Day (MOTD)

Enables/disables the display of the message of the day.

Default: Disabled Multisessions The number of extra network connections available on a serial port (available

only on 2 port+ models), in addition to the single session that is always

available. Enabling multisessions will permit multiple users to monitor the

same console port. Each user monitoring the port can be assigned different

privileges to this port.

Data Range: 0-7 multisessions per serial port

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

Serial Port Profiles

TruePort 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.

Functionality

TruePort is a COM port redirector utility for the IOLAN. It can be run in two modes (these mod e s 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.

Terminal Profile

Overview

The Terminal profile allows network access from a terminal connected to the IOLAN’s serial port. This profile is used to access pre-defined hosts on the network from the terminal.

Functionality

This profile can be setup in two ways:

1. The user can be required to log into the IOLAN and then a connection to a host can be

established.

2. The user connecting to the serial port will be directly connected a host.

Serial Tunneling Profile

Overview

The Serial Tunneling profile allows two IOLANs to be connected back-to-back over the network to establish a virtual link between two serial ports based on RFC 2217.

Functionality

The serial device that initiates the connection is the Tunnel Client and the destination is the Tunnel

Server

, although once the serial communication tunnel has been successfully established,

communication can go both ways.

Serial Port Profiles

A more detailed implementation of the Serial Tunneling profile is as follows:

The IOLAN serial port signals will also follow the signals on the other serial port. If one serial port receives DSR then it will raise DTR on the other serial port. If one serial port receives CTS then it will raise RTS on the other serial port. The CD signal is ignored.

Configure the following parameters:

Act As Tunnel Server

The IOLAN will listen for an incoming connection request on the specified

Internet Address on the specified TCP Port.

Default: Enabled

TCP Port The TCP port that the IOLAN will listen for incoming connection on.

Default: 10000+serial port number; so serial port 2 is 10002.

Enable TCP Keepalive

Enables a per-connection TCP keepalive feature. After the configured number of seconds, the connection will send a gratuitous ACK to the network peer, thus either ensuring the connection stays active OR causing a dropped connection condition to be recognized.

This parameter needs to be used in conjunction with

Status Interval parameter found in the Serial, Advanced, Advanced Settings

Monitor Connection

tab. The interval determines how long the IOLAN will wait during inactivity before "testing" the connection. It should be noted that if a network connection is accidentally dropped, it can take as long as the specified interval before anyone can reconnect to the serial port.

Default: Disabled

Act as Tunnel Client

The IOLAN will initiate the connection the Tunnel Server.

Default: Disabled

Host Name A preconfigured host name that is associated with the IP address of the Tunnel

Server.

TCP Port The TCP port that the IOLAN will use to connect to the Tunnel Server.

Default: 10000+serial port number; so serial port 5 is 10005.

Virtual Modem Profile

Overview

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

device. It will respond to AT commands and provide signals in the same way that a serially attached modem would. This feature is typically used when you are replacing dial-up modems with the IOLAN in order to provide Ethernet network connectivity.

Functionality

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).

Default: Enabled Host Name The preconfigured target host name. TCP Port The port number the target host is listening on for messages.

Default: 0 (zero) Connect Manually

Via AT Command

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 Phone Number to

When your modem application provides a phone number in an AT com mand

string, you can map that phone number to the destination host .

window that appears when you click this button.

Send Connection Status As

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 Success String String that is sent to the serial device when a connection succeeds.

Default: CONNECT <speed>, for example, Failure String String that is sent to the serial device when a connection fails.

Default: NO CARRIER
