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 Getting 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.
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 for information on configuring/managing the IOLAN with DeviceManager.
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/Quick Access Buttons Navigation Tree Display Area Download Button Navigating the Options The left-hand navigation tree allows you to quickly and easily navigate the various Configuration and Statistics pages of DeviceManager.
WebManager Downloading the Configuration When you have completed all your configuration changes, click the Download All Changes button to download the configuration to the IOLAN. You must reboot the IOLAN for your configuration changes to take effect. 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.
WebManager 3.
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 . 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 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 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 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 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.
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® 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.
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: 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 Connect 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.
Navigating DeviceManager/WebManager WebManager The WebManager uses an 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. Whenever you connect to the IOLAN through the DeviceManager, you connect as the Admin user and must supply the password for the Admin user.

Serial Port Profiles 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.
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.
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.
Serial Port Profiles This entry is disabled since Direction is set to Disabled. General Tab Field Descriptions Configure the following parameters: Listen for connections on UDP port The IOLAN will listen for UDP packets on the specified port. Default: 1000+ (for example, 10001 for serial port 1) Direction The direction in which information is received or relayed: z Disabled—UDP service not enabled.
Serial Port Profiles Port The UDP port to use. Default: 0 (zero) Advanced Tab Field Descriptions Configure the following parameters: Session Strings Controls the sending of ASCII strings to serial devices at session start 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 the serial port.

11 Configuring the System Chapter 11 Introduction This chapter describes the alerts (syslog) that can be configured for the IOLAN and the advanced options (SNMP, custom applications/plugins, and other miscellaneous configuration options) that you will want to look at to see if they are required for your implementation. Alerts Syslog Overview The IOLAN can be configured to send system log messages to a syslog daemon running on a remote host if the Syslog service is activated.
Management Secondary Host If the IOLAN cannot communicate with the primary host, then the IOLAN will attempt to send system log messages to this preconfigured host; messages will be displayed on the host’s monitor. Default: None Level Choose the event level that triggers a syslog entry.
Management Internet Address The IP address of the SNMP manager that will send requests to the IOLAN. If the address is 0.0.0.0, any SNMP manager with the Community name can access the IOLAN. If you specify a network address, for example 172.16.0.0, any SNMP manager within the local network with the Community name can access the IOLAN. Field Format: IPv4 or IPv6 address Permissions Permits the IOLAN to respond to SNMP requests. Data Options: z None—There is no response to requests from SNMP.
Management Community The name of the group that devices and management stations running SNMP belong to. Community only applies to SNMP v1 and v2c. Inform Timeout This is only used for Inform traps. Select the number of seconds to wait for the acknowledgement of the trap. T Default: 1 second. Retires This is only used for Inform traps. Select the number of times the trap will be sent if no acknowledgement is received.
Management Configure the following parameter: Command Line The name of the application that has been already been downloaded to the IOLAN, plus any parameters you want to pass to the program. For example, using sample outraw program (this is sample program supplied with the SDK), you would type: outraw -s 0 192.168.2.1:10001 Acct:10001 if you were starting the application on the Server (notice the -s 0 parameter specifies serial port 1 to this particular application).
Management Use a Generic WebManager Login Screen When set, and the user connects to the IOLAN using WebManager, the WebManager login screen that is displayed is generic — the Perle banner, IOLAN model name, and firmware version are not displayed to the user. Default: Disabled Password Retry Limit The number of attempts a user is allowed to enter a password for a serial port connection from the network, before the connection is terminated and the user has to attempt to login again.
Management Message of the Day (MOTD) Tab Field Descriptions The message of the day is displayed when users log into the IOLAN through a telnet or SSH session or through WebManager or EasyPort Web. There are two ways to retrieve the message of the day to be displayed to users when they log into the IOLAN: z The message of the day file is retrieved from a TFPT server every time a user logs into the IOLAN.
Management TFTP Tab Field Descriptions You must have a TFTP server running on any host that you are uploading or downloading files to/from. Note: TFTP file transfers send via UDP packets. When the packet delivery is interrupted for any reason and a timeout occurs, that packet is resent if the retry count allows it. Therefore, if a very large file is being transferred and is interrupted, the entire file is not resent, just the part of the file that was not received.
12 Controlling the I/O Channels Chapter 12 Introduction The Control section appears when the IOLAN is connected to an I/O model. I/O Channels Overview When the DeviceManager is connected to an I/O model IOLAN, the I/O Status/Control option is available. You can view the I/O status and manually control such options as clearing alarms, clearing minimum/maximum values, resetting the channel(s), and activating/deactivating output.
I/O Channels Activate Output Button Manually activates the channel output. Deactivate Output Manually deactivates the channel output. Button Reset All Channels Resets all the channels. Button Refresh Button Resets the highlighted channel (click on a channel to highlight it).
13 System Administration Chapter 13 Introduction This chapter addresses the functions that the admin user or a user with Admin Level privileges might do. This chapter uses the DeviceManager as the configuration method described in most administrative functions. As a general rule, administrative functions are accessed from the menu bar in the DeviceManager and under the Administration option in the WebManager’s navigation tree.
Managing Configuration Files Downloading Configuration Files You can download a configuration file to the IOLAN by doing the following: z z In DeviceManager: 1. Connect to the IOLAN to retrieve the current configuration file. 2. Open the configuration file you want to download to the IOLAN by selecting File, Import Configuration from a File and then browsing to the configuration file. This will replace the retrieved configuration file. 3.
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.
Managing Configuration Files 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.
Downloading IOLAN Firmware Resetting the IOLAN to the Default Configuration The RESET button on the IOLAN allows you to reset the IOLAN to its Perle or custom factory default configuration. The Power/Ready LED color and the resetting of the IOLAN default configuration vary depending on how long you press and hold the RESET button, as shown in the table below. When you press and hold the RESET button for...
Calibrating I/O Calibrating Voltage When calibrating the IOLAN Analog input for voltage, you will need a calibration meter that is better than .1% volts precision. When you calibrate one channel, all voltage 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 also automatically calibrated.
Calibrating I/O Calibrating Temperature Input To calibrate an Analog (Temperature) input channel, read the section that applies to the type of input you are calibrating. Note that calibration will be done for the active channel configuration; for example, if Channel A1 is set to thermocouple, you cannot calibrate it for RTD.
Calibrating I/O Calibrating Analog Channels Analog Input can be calibrated for Analog and Temperature IOLAN models. Select the channel you want to calibrate. This example uses an A4 model that has channel A1 set to Current with a Range of 0 to 20mA. If you have not disabled confirmation messages (Tools, Options in DeviceManager only), you will get prompted to verify channel calibration. Click Yes to proceed with calibration.
Setting the IOLAN’s Date and Time 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. For example, if you are connecting to the IOLAN through the DeviceManager and your PC’s time zone is set to Pacific Standard Time (GMT -8:00) and the IOLAN’s time zone is set to Eastern Standard Time (GMT -5:00), the IOLAN’s time is actually three hours ahead of your PC’s time.
Language Support Language Support Two language files, in addition to English, are supplied on the supplemental CD, French and German. You can use any of these language files to create a translation into a language of your choice. You can download the language file (whether the language is supplied or translated) into the IOLAN and select the Language option of Custom Language or Customlang (custom language), making the Menu and CLI field labels display in the desired language.
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, VT320-7, and HP700/44.
Resetting Configuration Parameters For example: term=AT386 | at386| 386AT |386at |at/386 console acsc=jYk?lZm@qDtCu4x3 bold=\E[1m civis= clear=\E[2J\E[H cnorm= cup=\E[%i%p1%02d;%p2%02dH rev=\E4A rmacs=\E[10m rmso=\E[m smacs=\E[12m smso=\E[7m page= circ=n Note: As you can see from the example, capabilities which are not defined in the terminfo file must still be included (albeit with no value). Each entry has an 80 character limit.
Lost admin Password Lost admin Password If the admin user password is lost, there are only two possible ways to recover it: z reset the IOLAN to the factory defaults z have another user that has Admin level rights, if one is already configured, reset the admin password 201
