3 Configuration Methods Chapter 3 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 Chapter 4, Getting Started on page 45 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.
Configuration Methods Overview 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.
Easy Config Wizard Easy Config Wizard The Easy Config Wizard is a configuration wizard that will configure all the serial ports on your IOLAN to one of the following: z Console Management z TruePort (Virtual COM Port) z TCP Sockets (Raw TCP) z Terminal z Printer (not supported on DS1/TS2 models) z Serial Tunneling You can launch the Easy Config Wizard from the Perle website or from the installation CD-ROM.
DeviceManager DeviceManager Overview The DeviceManager is a Windows-based application that can be used to connect to the IOLAN to actively manage and configure it or can create new IOLAN configurations offline. See Chapter 5, Using DeviceManager and WebManager on page 53 for information on configuring/managing the IOLAN with DeviceManager. Access Platforms The DeviceManager can be run from Windows 98/NT/2000/ME/Server 2003/XP/Vista.
DeviceManager All discovered IOLAN will be displayed on the list along with their name and IP address. When a new IOLAN is discovered on the network, that has not yet been assigned an IP address, it will be displayed with an IP Address of Not Configured. To configure the IP address, click on the IOLAN and then click the Assign IP button.
DeviceManager Using DeviceManager After you have successfully connected to the IOLAN, you will see the following window: Menu Options/Icons Navigation Tree Configuration/Info Download Button You navigate through the different configuration windows by selecting an option in the left-hand navigation tree. If double-click on option that is next to a folder, more navigation are displayed when you click on it: Navigation Tabs The Network folder contains two configuration options, IP Address and Advanced.
WebManager WebManager Overview The WebManager is a web-browser based method of configuring/managing the IOLAN. It follows the same design as the DeviceManager, so it is easy to switch between the WebManager and DeviceManager when configuring your IOLAN. See Chapter 5, Using DeviceManager and WebManager on page 53 for information on configuring/managing the IOLAN with DeviceManager. Access Platforms You can access the IOLAN through WebManager from any system that can run a web browser.
WebManager Using WebManager After you have successfully logged into WebManager, you will see the following: Navigation Tree System Information You navigate through the different configuration windows by selecting an option in the left-hand navigation tree. If click on option that is next to a folder, more navigation are displayed when you click on it: Navigation Tabs The Network folder contains two configuration options, IP Address and Advanced.
Command Line Interface Command Line Interface Overview The Command Line Interface (CLI) is a command line option for IOLAN configuration/management. See the Command Line Interface Reference Guide for a full breakdown of all the CLI commands and their functionality. Access Platforms The CLI is accessed by any application that supports a Telnet session to the IOLAN’s IP address, such as Putty, SecureCRT, or from a command prompt.
Menu Through the Serial Port To connect to the IOLAN through the serial port to configure/manage it using the CLI (or Menu), see Using a Direct Serial Connection to Specify an IP Address on page 47. After you have established a connection to the IOLAN, you will get a Login: prompt. You can login as the admin user or as a user with Admin Level rights.
Menu Using the Menu After you have successfully logged in, type screen at the prompt and press Enter. You will be asked to enter a terminal type, and then you will see the following Menu: To navigate through the Menu options, do the following: 1. Highlight a Menu option by using the keyboard up and down arrows to navigate the list. 2.
DHCP/BOOTP 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.
DHCP/BOOTP 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.
SNMP 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.
SNMP Using the SNMP MIB After you have successfully connected to the IOLAN through your SNMP Management tool or MIB browser, expand the PERLE-IOLAN-DS-MIB folder to see the IOLAN’s parameter folders. Below is an example of the configurable parameters under the ServicesInfo folder. The first variable in each folder is the Status variable, for example, serviceStatus.

4 Getting Started Chapter 4 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 minimally consists of configuring an IP address or enabling DHCP/BOOTP.
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.
Setting Up the Network 10. Expand the Server Configuration folder and select Server. Verify the IP address configuration. You should also enter a name in the Server Name field to make the IOLAN easily identifiable. 11. To make your edits take effect, you need to download the new configuration file and then reboot the IOLAN. Download the configuration file to the IOLAN by selecting Tools, Download Configuration to Unit or click the Download All Changes button. 12.
Setting Up the Network 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).
Setting Up the Network 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.
Setting Up the Serial Port(s) Setting Up the Serial Port(s) The DeviceManager and WebManager have the following serial port profiles that will simplify serial port setup: 50 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.
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.
Setting Up Users Setting Up Users When you have a user who is accessing a device connected to a serial port from the network or who is accessing the network from a device connected to a serial port through the IOLAN, you can create a user account and configure the user’s access privileges. Notice that there is a Default user; the Default user’s parameters are inherited by users accessing a serial port configured for the Terminal profile with the Conenct to remote system option enabled.
5 Using DeviceManager and WebManager Chapter 5 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.
Navigating DeviceManager/WebManager Navigating DeviceManager/WebManager The DeviceManager and WebManager have very similar navigation methods. The left-hand side of the manager is the navigation tree and the center is the configuration area. The DeviceManager has menu and quick access buttons, whereas the WebManager has system information and some navigation options on the far right-hand side. DeviceManager The DeviceManager uses a folder/page navigation tree.
Navigating DeviceManager/WebManager WebManager The WebManager uses a expandable/collapsible buttons with folders and pages for the navigation tree. You can expand the buttons to view the folders and pages to see the available configuration options. When you access a configuration page, you can often navigate the tabs in the configuration area to access all of the configuration options.
Using DeviceManager to Connect to the IOLAN Using DeviceManager to Connect to the IOLAN DeviceManager can connect to existing IOLANs or assign an IP address to a new IOLAN.

Managing Configuration Files Downloading Configuration Files to Multiple IOLANs You can download a configuration file to multiple IOLANs at the same time by doing the following in DeviceManager (DeviceManager is the only configurator that does this function): 1. Select Tools, Download Configuration to Multiple IOLANs. 2. Specify the IOLANs that you want to download the configuration to: Enter the following information for each IOLAN that you want to configure with the same configuration file: 3.
Downloading IOLAN Firmware 4. Click the Download> button to start the download process. A status window will display with the configuration download status. Uploading Configuration Files When you upload a configuration to the DeviceManager, you are uploading the IOLAN’s working configuration file. In most other configurators (the exception being SNMP), you are always seeing the working configuration file. In DeviceManager, select Tools, Upload Configuration from IOLAN.
Calibrating I/O Calibrating I/O All I/O channels are factory calibrated and should not need recalibration during initial use. However should calibration be required, you can recalibrate in DeviceManager or WebManager. In DeviceManager, you calibrate the I/O channel(s) by selecting Tools, I/O Channels, Calibrate. In WebManager, you calibrate the I/O channel(s) by selecting I/O Channels, Calibrate.
Calibrating I/O Calibrating RTD When calibrating the IOLAN Analog input for RTD, you will need a resistor that is better than .05% Ohms accuracy. When you calibrate one channel, all RTD channels are automatically calibrated for that range; if another channel is set for a different range, you will need to calibrate that channel separately, but all channels that use that range are automatically calibrated. Calibrating Analog Channels Analog Input can be calibrated for Analog and Temperature IOLAN models.
Setting the IOLAN’s Date and Time Resetting Calibration Data You can reset the I/O channels calibrations to the factory calibrations in DeviceManager by selecting Tools, I/O Channels, Reset Calibrate Data or in WebManager by selecting Administration, Reset, I/O Calibration. Setting the IOLAN’s Date and Time When you set the IOLAN’s time, the connection method and time zone settings can affect the actual internal clock time that is being set.
Resetting the IOLAN to Factory Defaults Resetting the IOLAN to Factory Defaults You can reset the IOLAN to its factory default configuration by selecting Tools, Reset, Reset to Factory Default in DeviceManager and Administration, Reset, Factory Defaults in WebManager. The IOLAN will automatically reboot itself with the factory default configuration. Language Support Two language files, in addition to English, are supplied on the supplemental CD, French and German.
Language Support Translation Guidance To help you with your translation, of supplied ASCII text language files we offer the following guidance: z The IOLAN will support languages other than English (and the supplied German and French languages). The English language file, english.txt, displays the character length of each line at the beginning of the line. If a translated line goes over that character length, it will be displayed truncated in the Menu or CLI.
Downloading Terminal Definitions Downloading Terminal Definitions All terminal types can be used on the IOLAN. Some terminal types which are not already defined in the IOLAN, however, are unable to use Full Screen mode (menus) and may not be able to page through sessions properly. When installed, the IOLAN has several defined terminal types—Dumb, WYSE60, VT100, ANSI, TVI925, IBM3151, VT320, and HP700.

G Troubleshooting Appendix G Introduction This chapter provides information that can help resolve problems with the IOLAN. Hardware Problems If the IOLAN Power/Ready LED is red and stays red for over 10 seconds, you have a hardware problem that might to require factory service. First, try the following: z If the IOLAN is not in Console mode, do the following: a. Set up a direct connection to the IOLAN; see Through the Serial Port on page 38 for information on this type of connection. b.
DeviceManager Problems z If the WebManager or DeviceManager cannot communicate with the IOLAN, verify that the Security, Services HTTP parameter is enabled for WebManager and DeviceManagerD is enabled for DeviceManager. DeviceManager Problems Error Message: 16 bit Windows Subsystem - C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'Close' to terminate the application.
Problems with Terminals Problems with Terminals The following section concerns problems with the appearance of data on your terminal screen. The IOLAN logs me out after a few minutes: z Check the Idle Timer value set for the user. The default setting for the Idle Timer for all users is 0 seconds (does not timeout). Corrupt data. z Check your line settings (baud rate, stop bits, etc.) Missing data. z Verify that the same type of flow control is set in both your terminal and on the IOLAN’s port.
DHCP/BOOTP Problems DHCP/BOOTP Problems Messages: host name too long or filename too long. z The IOLAN can only accept host names of 14 characters or file names of 64 characters, so verify that you are not attempting to pass a string that is longer than those maximums. DHCP or BOOTP have been set up to configure my IOLAN, but does not seem to have done anything. z Check that the server DHCP/BOOTP service is set to on, if not set it to on and reboot.
Glossary This chapter provides definitions for Device Server terms. BOOTP (BOOTstrap Protocol) An Internet protocol that enables a diskless workstation to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive. Callback A security feature where the Device Server calls back the User at a predetermined number defined in the User’s account.
PAP (Password Authentication Protocol) Standard authentication protocol for PPP connections. see CHAP RADIUS (Remote An open standard network security server that communicates with the PAP protocol. Authentication Dial In Users Services) Reverse Connection Connections that originate from a host that go directly to a serial device through the Device Server. RIP (Routing A protocol that allows gateways and hosts to exchange information about various routes to Information Protocol) different networks.
