About This Guide

Introduction

Purpose

This user guide provides the following:

• Configuration and administration procedures

• Configuration examples

Audience

This guide is intended for the person responsible for configuring and administering device server. It assumes that this person has experience configuring network devices and is familiar with networking concepts.

Scope

This guide provides step-by-st ep instructions for configuring and administering your Digi device’s main features. It focuses on performing these tasks through the Web user interface. It does not address how to configure ever y option, provide complete inf ormation on commands, or discuss hardware installation. These topics are covered in other documents in the Digi library.

Setup Overview

Following is an overview of the process for setting up a device in the Digi TS family of devices for use. The rest of this guide provides details on each step of the process.

Step A: Plan

Before beginning setup, consider the following:

• How to assign an IP address to the Digi device’s Et hern et i nt erface , which can be accomplished in a number o f ways. See "Configuring the IP Address" on page 13.

• How to configure serial ports. A key consideration is whether to use RealPort. Other considerations include the type of peripheral t hat will connect to the port and the peripheral’s cabling requirements. See "Setting Up RealPo r t" on p a ge 35 and the online RealPort driver documentation and Cable Guide, both of which are on the Software and Documentation CD.

• The various ways in which your Digi device can be configured. See "About Configuration Methods" on page 9 for more information.

Step B: Set Up the Hardware

1. If the Digi device supports multiple serial port interfaces (EIA-232, EIA-422/485), set the interface with the dip switches on the device.

2. Connect the device to the network.

3. Connect peripherals to serial ports. See the Cable Guide on the Software and Documentation CD.

4. Connect the power supply to the Digi device.

Step C: Install and Setup Digi Port Authority-Remote

Digi Port Authority-Remote is a utility that provides one of the ways to configure an IP address and also provides port monitoring.

Step D: Configure an IP Address

There are a number of ways to configure an IP address. See "Configuring the IP Address" on page 13 for more information.

Step E: Configure Ports

See the following for mo re information:

• "Setting Up RealPort" on page 35

• "Network Settings" on page 17

8 Chapter 1 Introduction

Supported Devices

Step F: Configure Other Features as Required

See the following for information on setting up other features:

• "PPP Settings" on page 31

• "Configuring Autoconnection" on page 43

• "Configuring IP Routing" on page 47

• "Configuring S ec urity Features" on page 49

• "Special Features:Domain Name Sy stem (DNS)" on page 63

This manual prov ides information on the following Digi devices:

• Digi One TS, Digi One TS H (high temperature), and Digi One TS

Wireless

• PortServer TS 1/3 + Modem

• PortServer TS 2/4, PortServer TS 2/4 MEI, PortServer TS 2/4 H,

PortServer TS 2/4 MEI H, and PortServ er 2/4 Wireless

Rack

About Configuration Methods

Use this section to learn about the different configuration methods.

Configure the Digi Device with the Wizard

Simply follow the prompts and choose your configuration with the wizard. Choose either a Microsoft Windows or Unix platform.

Configure the Digi Device from an Attached Terminal

With this method, you cable a terminal or PC running terminal emulation software to a device server port and then use the command line to enter commands. This method allows you to configure a ll features. It requires, however, that you and the device server be in the same location. Some users find it advantageous to configure the device server IP address this way and then u se one of the othe r met hods for t he rest of the configu ration .

Configure the Digi Device from a Telnet Session

With this method, you Telnet to the device server and use the command line to complete configuration tasks. The only disadvantage to this method is that you have to configure the device server with an IP address before you can Telnet to it.

Configure the Digi Device from the Web Interface

The great advantage to this method is ease of use. This method requires that you configure the IP address before you can access the configuration from the web interface, however, some features cannot be configured this way.

Chapter 1 Introduction 9

Downloading a Configuration File

With this method, you configure a Digi device and then do the following:

1. Download an existing configuration file to a host system.

2. Edit the file with specific configuration using a text editor.

3. Upload the file to the device server.

This an excellent method for maintaining highly similar configuration files for multiple Digi devices. The disadvantage is that the device server requires some configuration steps, such as the IP address, to be completed before it can be used.

Accessing the Configuration from the Web Interface

To access the configuration from the web interface, follow these steps. This procedure assumes that you have configured the Digi device with an

IP address already. See "Configuring the IP Address" on page 13.

1. Access the Digi device from a web browser by specifying the device server’s IP address in the URL window.

2. Log on as root. The default password is dbps.

Configuring the IP Address

The next step in the device configuration process is to configure an IP address and access the device for more advanced configurations. You must set the initial IP before you can use the web interface. Once the IP is set, the device can be accessed through the web interface and any changes made including cha ngin g the IP add ress.

Options for Configuring the IP Address and Mask

The device server IP address can be configured using the following methods:

• With the Wizard from the Software and Documentation CD. (Insert

the CD and the wizar d auto mati cally po p s up f or Micr osof t Window s systems. If you have a UNIX system see the back of the quick start guide for mounting instructions.)

• With Digi Port Authority-Remote, a Digi utility on the Software and

Documentation CD.

• From the command line, using the set config command. See the

Digi Command Reference for more details.

• By updating the ARP table on a server and then pinging the Digi

device (called ARP-Ping, see "Configuring the IP Address Using ARP-Ping" on page 14).

• Using a DHCP server ("Configuring an IP Address using DHCP and

RARP" on page 15.)

• Using a RARP server ("Configuring an IP Address using DHCP and

RARP" on page 15.)

The IP address and mask can also be changed using the web interface, but not for initial IP address configuration.

Device Support: Digi Port Authority-Remote and ARP-Ping for IP Address Configuration

Not all Digi devices can use Digi Port Authority-Remote and ARP-Ping for IP address configuration. To determine if you can use these features, find the hardware label on your Digi device and then use the table below to determine whether this feature is available:

Device Part Number Revision Required

Digi One IA RealPort 50000764-01 F or higher Digi One RealPort 50000723-01 J or higher PortServer TS 2 50000723-02 J or higher PortServer TS 4 50000723-03 G or higher

Chapter 2 Configuring the IP Address 13

Configuring the IP Address with Digi Port Authority-Remote

Use this section to configu re an initial IP add ress, subnet mask, and defau lt gateway using Digi Por t Autho rit y-Re mote. Thi s proce dure cannot b e used to change the IP address, but only to assign the initial IP address. It also cannot be used if a DHCP server is act i ve.

Assumptions

This procedure assumes the following:

• That your Digi device supports this feature. See "Device Support:

Digi Port Authority-Remote and ARP-Ping for IP Address Configuration" on page 13.

• That your Dig i device is connected to the Ethernet network.

• That the Digi device has DHCP client turned on. This is the default

setting and it will be on unless it was turned off.

• That you do not have a DHCP server to serve IP ad dress. If you d o,

use the DHCP procedure. See "Configuring an IP Address using DHCP and RARP" on page 15.

• That you have installed Digi Port Authority-Remote version 2.01.11

or later. Click the Help button on the tool bar in Digi Port AuthorityRemote to check the version number.

Procedure

1. Run Digi Port Authority-Remote.

2. Click Discover. A list of Digi devices appears. Systems with IP addresses of 0.0.0.0 nee d IP addresses.

3. Select a device from the list and then click Configure.

4. Supply an IP address, subnet mask, and default gateway and then choose OK.

Digi Port Authority-Remote configures the IP address, subnet mask, and default gateway.

Configuring the IP Address Using ARP-Ping

An IP address can be configured by manually updating a server’s ARP table and then pinging the Digi device.

Note: The ARP-Ping command assigns the IP address you designate but also

assigns default subnet mask and gateway addresses. It is necessary to change the subnet mask and gateway addresses.

Assumptions

This procedure assumes the following:

• That your Digi device supports this feature. See "Device Support:

Digi Port Authority-Remote and ARP-Ping for IP Address Configuration" on page 13.

• That your Dig i device is connected to the Ethernet network

14 Chapter 2 Configuring the IP Address

Procedure

1. Record the MAC address of th e Digi device. The MAC addr ess is on the back of the unit.

2. Access a server on the same subnet as the Digi device.

3. Manually updat e the server’s ARP table using the Digi device’s MAC address and the IP address you want assigned to the Digi device. The following is an example of how this is done on a Windows NT 4.0 system:

arp -s 143.191.2.1 00-00-9d-22-23-60

4. Ping the Digi device using the IP address just assigned. The following is an example:

ping 143.191.2.1

The ping will probably time out before there is a response from the Digi device.

5. Wait several seconds and then ping the Digi device again. The Digi device replies to the ping, indicating that the IP address has

been configured.

Configuring an IP Address using DHCP and RARP

About DHCP and RARP

When the device server boots, it transmits a DHCP request and a RARP request. This continues until an address is assigned.

Procedure

To use RARP or DHCP follow these steps:

1. Set up an entry for an address on a DHCP or RARP server. If you intend to use RealPort, do the following:

• Reserve a permanent IP address.

• Record the IP address. You will need it when you configure the

2. Power on the device server.

The DHCP or RARP server assigns the device server an IP address.

Accessing the Digi Devi ce

1. Enter the IP address in the URL bar of your browser.

2. Enter your login name (root) and password (dbps).

Note: The following screen appears allowing you to configure the device for your

RealPort driver.

Network Settings

Configuration

The next step in the device setup process is to configure the network and serial port settings. In order t o access the web in te rfa c e an IP addre ss must be assigned. It is assumed you have logged onto the web interface using the username, root and password, dbps in order to make any changes or additional configuration assignments. However, it is important to note that if you have used the wizard, your configuration is complete and you do not additional changes.

1. Click Network to view the IP settings or make any changes to the IP address.

2. Click Advance Network Settings.

Chapter 3 Configuration 17

Adjust the network settings to fit your configuration needs. If you need additional information use the Help button on the top right hand corner of the configuration screen.

3. Click Apply to save any changes you make.

4. Click Reboot for changes to take effect.

Procedure for Using a Name Server

To configure a DNS server, follow these steps:

1. Click Network and select Use the following IP address.

2. Enter the IP address for the DNS server in the Name Server box. The DNS server maps names (MyDeviceName.mycompany.com) to IP addresses (192.105.1.2).

3. Enter a name for a group of network devices.

4. Enter the domain name that this device will live in and is tied to the DNS server address assigned in step 2. This name can be used by other network devices to talk to it, instead of using the its IP address. Get this name from the network administrator, because it must be entered in the DNS server to work properly.

5. Enter the Base Socket. The base socket is the incoming port number which remote devices need to use to access the device using the named protocols.

Note: Base Socket

This determines which network port (socket) on this Digi terminal server another network device (such as another Digi terminal server or a PC) uses to communicate using certain services. Most applications can leave this value unchanged. To calculate these settings: Telnet port = Base Socket + Serial Port Number Raw port = Base Socket + 100 + Serial Port Number

3. Click Change Profile and select a profile based on the device you have connected to your port.

Note: The following section shows the settings available for each profile.

Chapter 3 Configuration 19

Note: The ‘More’ link will describe the profiles with additional information.

Note: Profiles appear depending on your device. Naturally, if you do not have a

device capable of a specific profile such as Power Management or Wireless, you will not have that particular profile available.

4. Click Apply to save the profile. The interface will determine any additional settings and advise you what tab to click next. See "Port Profiles" on page 21 or click Help for additional information.

5. A port profile or port options page will come up and ask for additional parameters if needed. Enter the appropriate parameters and click Apply.

6. Click Reboot for changes to take effect.

20 Chapter 3 Configuration

Port Profiles

Each port profile determines the setti ngs nee de d. The fol low i ng screenshots of each profile show the port settings. For a complete description of each profile click the Help button.

RealPort

Installed on a network-based PC, Rea l Port emulates a serial port. That is, the application “t hinks” it is working with a real serial port, such as COM1. When the applicatio n sends dat a to this serial port, RealPor t ship s the data across the network to the device server which in turn routes it to the serial device. This is also referred to as COM Port Redirection. The network is transparent to both the application and the device.

Console Management

Access a device's console port over a network connection. Most network devices such as routers, switches, and servers offer serial port(s) for management. Instead of connecting a terminal to the console port, ca ble the console port to the serial port of your Digi device. Then using TCP/IP utilities like reverse telnet, network administrators can access these consoled serial ports from the L AN.

Chapter 3 Configuration 21

TCP Sockets

TCP socket communication enables serial devices to communicate with each other over an Ethernet network as though they were connected by a serial cable.

Configuring TCP socket communications involves configuring the Digi device for the following types of c onnections:

• Inbound connections, that is, connections that are initiated by the

device on th e other side of the network.

• Outbound connection, that is, connections that are initiated by the

device connected to the serial port.

Note: TCP Sockets profile is also the profile to use for Autoconnection. See "Click

UDP Sockets

Reboot for changes to take effect." on page 33 for more information.

The Digi TS Family devices are capable of UDP multicast. UDP multicast is used to send serial dat a over an Et hernet cable to one or many host s at the same time. UDP is a ‘connectionless’ protocol, meaning UDP does not need a protoc ol , b ut i s se nding data wi thout any form of acknowledgement or error correction. Up to 64 devices can receive a UDP multicast at one time. Both the transmitting and receiving devices must be configured properly for UDP multicast to work.

Configuring UDP multicast communications involves configuring the D i gi device for the following types of c onnections:

• Inbound connections, that is, connections that are initiated by the

device on th e other side of the network.

• Outbound connection, that is, connections that are initiated by the

device connected to the serial port.

22 Chapter 3 Configuration

Note: The serial parameters for two connecting devices must match meaning if one

device is set for 9600 bps, the other device must be set for the same rate.

Serial Bridging

A serial bridge is a network connection between two serial devices, each of which uses a device server. The serial devices “think” they are communicating wit h each other across a serial cable using serial communication techniques. There is no need to reconfigure the server or the serial device. Neither is aware of the intervening network.

This profile configures each side of the bridge separately. Repeat the configuration for the secon d Dig i device se rve r o f the bridge sp eci fyi ng the IP address of the first Digi device server.

Chapter 3 Configuration 23

Printer

This profile allows you to con nect a printer to a serial port. Use this profile i f you intend to print using the lpd protocol on your UNIX system.

Note: Refer to your UNIX User Guide for tips on configuring the print spooler on

your UNIX system.

Terminal

This profile allows you to connect to a terminal to the serial port.

24 Chapter 3 Configuration

Industrial Automation

The Industrial Autom ation (IA) Profile all ows you to co nnect IA device s and PLCs to the serial port in order to network-enable the devices. Use this profile if you need to communicate over the network with an IA device or PLC that only uses serial protocols. This profile may also be used to add routing capabilities to IA devices or PLCs that act as serial masters and send packets to various systems or devices on the network. Industrial Automation enhances the IA device or PLC connected to the serial port.

Modem Profiles

There are 3 types of modem profiles :

• Modem Emulation

Modem Emulation allows the Digi device to function as a modem. A short description follow the modem profiles listed below. For more specific informat ion about Mo dem Emulat ion see "Special Features: Modem Emulatio n" on page 43, including AT commands specific to this function.

• Modem

The Modem profile configures the Digi device for attaching a modem to a serial port. For more specific information about the modem profile use the H elp button in the upper right corner on the profile page of the web inter f a c e.

• Internal Mode m

The Internal Modem profile (not liste d in the graphic) is specific to the PortServer TS 1/3+Modem devices. The fully functioning

Chapter 3 Configuration 25

modem is embedded in port one and uses the standard AT command set. See the Documentation on the Digi CD for the complete AT Command Reference.

Modem Emulation

Modem Emulation allows you to configure the serial port to act as a modem. The Digi device emulates modem responses to a serial device and seamlessly sends an d receiv es dat a ov er an Eth ernet ne twork i nstea d of a PSTN (Public Swit ched Telephone Net work). The advan tage f or a user is the ability to retain legacy software applications without modification and use a less expensive Ethernet network in place of public telephone lines.

Modem

Modem allows you to attach modem devices to the serial port in order to establish or receive connections from other systems and modems.

Note: Click the PPP Configuration link to set up incoming, outgoing or advanced

PPP settings if the attached modem uses PPP connections. See "System Configuration" on page 31 for more information about PPP settings.

Power Management

The Power Controller feature allows the administrators of the Digi CM to use console management to control power function s. Power control consists of three basic functions: on, off, and reboot (power cycle).There are two typical scenarios when using a power controller. The simplest scenario is a non-serial device connected to a power controller (for example, an environmental sensor controller or a tape backup device).

Note: Power controller settings can be automatically detected or configured

User Configuration

Although it is not required, the device server is often configured to accommodate the requirements of particular users. Typical configurable user attributes include:

• Whether the user is required to supply a password.

• Autoconnection attributes, such as the system to which the user

should be automatically connec ted at login.

• The interface the device presents the user, such as a menu or

command line.

• Whether th e user has access to outbound ports.

Note: For information on configuring PPP users, see "PPP Settings" on page 31.

About RealPort

Setting Up RealPort

The next step in the device setup process is to configure RealPort. This section provides a brief introduction to RealPort. If you use the wizard, follow the steps in the pop-up after selecting the Incoming scenario.

What is RealPort?

RealPort is a feature that allows network-based host systems to use the ports of the device server as though they were the host system’s own ports, appearing and behaving as local ports to the network-based host.

RealPort Advantages

RealPort provides the following advantages:

• It expands the number of ports available to the host system.

• It enables device server ports to be treated as if they were directly

connected to the host, whi ch mean s they use al l st andar d opera ting system interfaces that control baud rate, parity, stop bits, and flow control.

• It enables host administrators to do most of the required

configuration on the host, the syst em with which th e administrator is most familiar.

• It dramatically reduces host CPU overhead because multiple

terminal or printer sessions are multiplexed over the same TCP/IP connection.

Configuring the RealPort Software

You must install and configure RealPort software on each host that will use RealPort ports. See the RealPort documentation for more information.

1. From the CD, click Software. (If the wizard pops up, click cancel.)

Modem Emulation

Special Features: Modem Emulation

The following Digi TS Family products include Modem emulation:

• Digi One TS

• Digi One TS Wireless

• PortServer TS 2/4 MEI

• PortServer TS 2/4 Wireless

• PortServer TS 1/3 + Modem

Note: Port one on the PortServer TS 1/3 + Modem is an actual embedded modem.

The remaining ports are capable of emulating a modem.

• PortServer 8/16

Modem emulation enables a system administrator to configure a networked Digi device to act as a modem. The Digi device emulates modem responses to a serial device and seamlessly sends and receives data over an Ethernet network instead of a PSTN (Public Switched Telephone Network) . The adva ntag e for a user is th e abil ity to reta in lega cy software applications without modification and use a less expensive Ethernet network in place of pub lic tele phone lines.

To use a Digi device for modem emulation, do the following:

• Use a cable with the correct wiring pinouts (see "Modem Emulation

Cable Signals" on page 44)

• Configure the serial ports and device type with the Web Interface

serial port profile - Modem Emulation

Common User Scenarios

The Digi device in modem emulation mode allows for the easy replacement of modems in almost any environment where there is a LAN or WAN.

In Diagram A, the Digi One TS repla ces a modem connected to a workstation running an application. The Digi One TS allows for the use of software applications without modification by responding to all the AT commands configured in the workstation application. The Digi One TS

Chapter 7 Special Features: Modem Emulation 43

connects to the IP Address of the server when an ATDT ipaddress:port (ATDT 192.168.25.5:50001) command is issued. Once the remote device establishes the TCP connection, a CONNECT message is sent to the serial port and only then does the Digi device switch from AT command mode to data mode. Using the modem escape sequence or dropping DTR on either side terminates the connection. A DISCONNECT message will be sent to the application if the remote side closes the TCP connection.

In Diagram B, two Digi devices will replace modems on both sides of the connection. The initiation of the connection occurs with either of the Digi devices. If both ends are Digi devices, the TCP listening port number is 50001 for port 1. An example of the connection command is ATDT

192.168.25.30:50001. Upon establishing a successful TCP connection, a CONNECT message is sent to the serial port and only then does the Digi device server switch from AT command mode to data mode. After the CONNECT is received, the transmi ssion of data begins. Using the modem escape sequence or dropping DTR on either side terminates the connection.

Modem emulation has the ability to communicate to an infinite number of other devices.

Modem Emulation Cable Signals

Use the following signal assignments to make a cable connecting the Digi device to a serial device.

DSR and DTR on the serial device side are connected to the DSR signal of the Digi device.

Scenarios for Modem Emulation

Outgoing Modem Emulation Connection

Serial device sends ATDx.x.x.x:y command, which triggers the device server to establish a telnet connection to destination IP=x.x.x.x, port=y.

Incoming Modem Emulation Connection

A device on the network telnets to port 50001 (50000+1 = 1st serial port). This incoming conn ection trig gers the device ser ver to gen erate a R ING on the serial port. The device attached to the serial port will answer the RING and the connection is established.

Modem Emulation Pooling

This is a combination of Incoming Modem Emulation Connection and a hunt group. A device on the network telnets to port 50000. The device server checks if a serial port configured for modem emulation is available. If so, it connects to the port, otherwise returns an error.

Modem Emulation Bridge

A combination of Outgoing and Incoming Modem Emulation Connections, in which both serial devices requir e to talk to a modem. The first serial device telnets to the second device using ATDx.x.x.x:y, the second device gets a RING and accepts the incoming telnet connect ion.

To send data to a Digi device server, enter the following information for your application replacing the telephone number with the Digi device server’s IP address and TCP port number. Enter the following command:

ATDT ipaddress:tcp_port#

an example is ATDT 146.135.13.5:50001

Answering Calls

The Digi device server listens on a pre-defined TCP port to receive data. When the Digi device server receives a call notification (RING) through a serial port to begin a TCP connection, it needs to reply with an ATA or a pre-configured Auto-Answer to answer the call.

Note: The TCP ports assigned to the serial ports are as follows:

Serial port 1 listens on TCP port 50001 Serial port 2 listens on TCP port 50002 Serial port 3 listens on TCP port 50003 Serial port 4 listens on TCP port 50004

Disconnecting Calls

Sets the number of rings required before the Digi Device Server automatically answers a call. Setting this register to Zero disables autoanswer mode.

Ring Counter S1 is incremented each time the modem

detects a ring signal on the telephone line. S1 is cleared if no rings occur over an eight second interval.

Escape Character S2 holds the decimal value of the ASCII char-

acter used as the escape character. The default value corresponds to an ASCII ’+’. A value over 127 disables the escape process, i.e., no escape character will be recognized.

Carriage Return Character Sets the command line and result code termi-

nator character. Pertains to asynchronous operation only.

Line Feed Character Sets the character recognized as a line feed.

Pertains to asynchronous operation only. The Line Feed control character is output after the Carriage Return control character if verbose result codes are used.

Backspace Character Sets the character recognized as a backspace.

Pertains to asynchronous operation only. The modem will not recognize the Backspace character if it is set to a value that is greater than 32 ASCII. This character can be used to edit a command line. When the echo command is enabled, the modem echoes back to the local DTE the Backspace character, an ASCII space character and a second Backspace character; this means a total of three characters are transmitted each time the modem processes the Backspace character.

Escape Prompt Delay Defines the maximum period, in fiftieths of a

second, allowed between receipt of the last character of the three escape character sequence from the DTE and sending of the OK result code to the DTE. If any characters are detected during this time, the OK will not be sent. Note that sending of the OK result code does not affect entry into command mode.

Serial Power Feature

Special Features: Power Over the Serial

The Serial Power feature available for the Digi One TS, PortServer TS 2 MEI, and PortServer TS 4 MEI allows the Digi device to power a serial device (power out) or use a serial device to power the Digi device (power in). The advantage of this feature is to eliminate an external power supply.

Power out is available on all ports through Ring Indicator (RI) or Data Terminal Ready (DTR). Power in is availab le only through RI and only on port one (1). The Seri al Power fe ature is ac tive on a spec ific port whe n that port is configured for RS 232 operation.

Ports

• The power out budget equals one (1) watt (the total amount of power available). The available pow er c an be divided in any combination between the ports but the following rules must be observed:

— RI = 5 volts @ up to 200 mA (max) — DTR = 9 volts @ up to 100 mA (max) — You may use DTR or RI as the source of power (power out) on

any port but you may not use bot h DTR a nd RI on the same po rt.

• Pinout information

Configuring RI Power

RI Power In

Ring Indicator (RI) power in accepts power into the Digi device server only on port one. Power in is availabl e using the RI pin . The Digi device r equires power in the range of 9-30 VDC @ 525mA (max). Ports 2, 3, and 4 can still supply power to a serial device through the RI or DTR pins for each port. When using power in through the RI, the external power supplies (both powered Ethernet and the barrel connector power supply) are inoperative. Altpin will not work for RI power in.

— RI is pin 1 —DTR is pin 9

• RI signaling is lost when the pin is used for power

Chapter 8 Special Features: Power Over the Serial Ports 59

1. Open the device unit enclosure and move the black jumper to the

ill

following settings: P-6 jumper on pins 1 and 2

Note: When the jumper is

placed correctly for power in, the jumper w set on the pins closest to the edge of the board. The left arrow indicates the open pin and the right arrow is pointing to the jumper.

2. Close the device unit enclosure.

RI Power Out

Ring Indicator (RI) power out is available on all ports. The total power budget for this featu re is one (1 ) watt not to exceed 5 volt s @ up to 200mA on any single port. The following procedure assumes the unit will only be used for RI power out.

1. Set the port DIP switches to the following place s: sw i tch 1 an d 3 are up and 2 and 4 are do wn (see "Serial Power Table" on page 61 for illustration).

2. Enable the RI power through the web interface.

3. Connect power su pply with the bar rel-connect or power sup ply provid ed with the device or use powered Ethernet.

Note: If the unit will be used with RI power in (port 1 only), set the jumper to the

Configuring DTR Power

Power Out

Data Terminal Ready (DTR) power out is the factory default on the Digi device server. Total power budget for th is feature is one w att no t to exce ed 9 volts @ up to 100mA to any single port.

1. Set the port DIP switches to EIA 232 (switch 1 is up, 2,3, and 4 are down) to enable DTR power.

following setting: P-6 jumper on pins 1and 2 and do not use an external power source. Port 1 cannot be used for both power in and power out.

60 Chapter 8 Special Features: Power Over the Serial Ports

2. Open the port and set DTR high.

Note Here are the pins to verify

the jumper position. The default position has the jumper on the two pins furthest from the edge. DO NOT MOVE THE JUMPER FROM THE DEFAULT UNLESS USING RI POWER IN.

Serial Power Table

If you are havi ng trouble with your unit after using the Power over port feature, you may have tripped the circuit breaker in the unit. You can identify this by the RI or DTR signal indicators found in the System Information under Administrat i on on the main menu in the web interface. Click the port number using serial power. (Remember serial power out is unavailable if the MEI settings are not 232.)

Under serial power will be a message if the breaker is tripped. Follow the instructions to reset.

From the command line use the two examples below for additional information.

Special Features: IA (Industrial

Automation)

Industrial Automation (IA) uses the Modbus protocol that defines how devices in an IA environment communicate. It specifies that a controlling unit, called a master, manages one or more units, called slaves. Only the master may initiate communication, and slaves may only respond.

Some of the element s of communication between devices that are defin ed by the Modbus protocol include:

• The structure of Modbus messages

• How the mast er requests infor m ation from the slave or specifies an

action for the slave to ta ke

• How the sla ve is to respond

• Addressi ng conventions

• Handling of many of th e other det ails req uired for communicati on to

occur.

Modbus defines two encod ing schemes: M odbus AS CII an d Modb us RT U. Each Modbus device uses one or the other.

Designed to function over a serial commu nication cab le, Modbus ha s been extended in rec ent years to fu nction over an Ethernet network using Modbus/TCP, which defines a method of encapsulating Modbus ASCII or Modbus RTU messages in IP packets for transport over the network.

The extermely flexible Digi implementation includes support for Modbus ASCII, Modbus RTU, Modbus/TCP, and two other methods of transport over a network, TCP socket and UDP socket communication. The implementation enables multiple net w ork-based masters to concurrently initiate communica tion w ith se r ial -b ase d sl a ves u si ng an y of th e su pp or ted network prot ocols.

Configuring Industrial Automation with Modbus

1. Click Serial Port > Change profile and select Industrial Automation.

2. Click Apply.

3. Under Profile settings, click change protocol.

4. Select the protocol that be st matches your environment (master or slave) Use the Help button for additonal information.

5. Enter the User defined protocol settings (Start delimiter, end delimiter, Message timeout, and Process ANSI escape characters) and click Apply.

6. Click Packet Routing > Add.

7. Enter the packet routing information. Click the Help button for additional information.

Note: Configure the serial port for the serial communication parameters (baud rate,

Chapter 9 Special Features: IA (Industrial Automation) 63

data bits, parity and stop bits) required by the connected IA device. If you configure the port for a slave, you do not have to configure a network-based master. Communication with the master just works. (If the master is

connected to a serial port, it must be configured, however.) If you configure a port for a master and the slaves are located on the network, TCP sockets, UDP sockets, and Modbus/TCP are all supported. Use the protocol required by the master.

Chapter 10

This chapter describes the configuring SNMP, the network management protocol that governs the exchange between nodes and stations.

About SNMP and the Device Server Agent

This section introduces SNMP and network management in TCP/IP networks and it describes the d evice server agent. It discusses the following:

• Network management components

• SNMP agent

•SNMP traps

• MIB support of the device server agent

• Support traps of the device server agent

Network Management Components

The TCP/IP network management architecture contains the following components:

• Managed nodes such as host systems, routers, terminal and com-

munications servers (such as device server) and other network devices.

Special Features: SNMP

• One or more network manager s (also called network manag ement

stations), which are the points from which the network is m anaged

• Agents that reside on managed nodes and retr ieve management

information and communicate this information to network managers.

• The network management protocol, SNMP, which governs the

exchange of inf ormation between the nodes and stations.

• Management information, which is the database of information

about managed objects. This database is called the management information base (MIB ).

SNMP Management Agent

Each managed node contains at least one agent—a component that responds to requests from the network manager—that retrieves network management information from its node and notifies the manager when significant events occur.

SNMP Traps

A mechanism defin ed by SNMP i s called a tr ap, which is a report or “a larm” from a managed node to an SNMP manager that a significant event has occurred.

MIB Support

The SNMP management agent supports the following MIBs:

Chapter 10 Special Features: SNMP 65

• Read-write for MIB II (RFC 1213), which is an Internet-standard

MIB, consisting of managed ob jects from the systems, inte rfaces, IP, ICMP, TCP, UDP, transmission, and SNMP group

• Read-write for the characte r-st ream d evice s usi ng SMIv2 MIB (RFC

1658)

• Read-write for the RS-232-like hardware devices MIB (RFC 1659)

• Read-write for the device server IP Network Control Protocol of the

Point-to-Point Protocol MIB (RFC 1473)

Message Support

The SNMP agent supports the Set, Get, GetNext, and Trap messages as defined in RFC 1157. These messages are used as follows:

• Set, which means set the value of a specific object from one of the

supported MIBs

• Get, which means retrieve the value of a specific object form one of

the supported MIBs

• GetNext, which means retrieve the value of the next object in the

MIB

• Trap, which means send traps to the manager when a particular

type of significant event occurs

Supported Traps

The agent can send traps when any of the following occur:

• Cold starts (d evi ce ser ver initi a lizes)

• Authentication failures

• Login attempts

Configuration Procedure: Web Interface

1. Click SNMP under System from the menu.

2. Fill in the configuration fields and click Apply to save settings.

3. Click Reboot for changes to take effect.
