Digi One Family and PortServer TSFamily

Digi One Family

The Digi One SP serial server provides reliable and cost-effective network connectivity for virtually any type of serial device.

This compact serial server supports a wide range of protocols using serial tunneling, TCP/UDP connections or Digi’s patented RealPort® COM port redirector for remote native COM port access. RealPort enables existing applications to communicate, without modification, with serial devices over the Ethernet as if they were communicating over a serial cable. Additionally, Digi One SP features modem emulation, allowing equipment designed for modem access to communicate transparently across the Ethernet.

PortServer TSFamily

PortServer TS serial servers offer RS-232 serial port expansion, making it easy to connect any serial device to your network. Available in 1, 2, or 4-port models, these serial servers combine the inherent benefits of data networking with proven asynchronous connectivity. They deliver powerful, yet simple Ethernet connectivity for all your serial devices.

PortServer TS device servers are ideal for applications requiring COM ports or where TCP/UDP Sockets or multicast functionality is required. All Digi device servers include Digi’s patented RealPort® COM port redirector technology, which makes it possible to establish a connection between the host and networked serial device by creating a local COM or TTY port on the host computer, allowing existing software applications to work without modification.

Device set up process overview

The following is an overview of the process for setting up your Digi device. The rest of this guide provides details on each step of the process.

Step 1: Deployment Considerations

Before beginning setup, consider the following:

n How to assign an IP address to the Digi device’s Ethernet interface, which can be accomplished

in a number of ways. See Configure the IPaddress.

n The various ways in which your Digi device can be configured. See Methods for configuring Digi

devices.

A key consideration is whether to use RealPort. Other considerations include the type of peripheral that will connect to the port and the peripheral’s cabling requirements. See

Configure Industrial Automation (IA) and the online RealPort driver documentation and Cable

Guide, both of which are available on the Digi website, www.digi.com.

Step 2: Set Up Hardware

1. Mount brackets to side of device for rack mounting.

2. Adhere the rubber feet to the bottom of the device for desktop.

3. Connect the device to the network.

4. Connect peripherals to serial ports.

5. Connect the device to the network.

6. Connect the power supply to the Digi device.

Step 3: Download Digi Device Discovery Utility

The Digi Device Discovery Utility is a tool to help you discover Digi devices on your network. From this utility’s interface, you can configure basic network settings and launch the configuration and management web interface for your device. You can download the Digi Device Discovery Utility from the Digi Device Discovery Utility support page.

Step 4: Configure an IP Address

There are a number of ways to configure an IP address. See Configure the IPaddress.

Step 5: Configure Ports

See the following for more information:

Methods for configuring Digi devices

Use this section to learn about the different methods for configuring Digi devices.

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 all 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 use one of the other methods for the rest of the configuration.

Note You cannot configure the Digi device from an attached terminal if you are using SP and DOIA. The

device type has changed from terminal to printer, which no longer allows access through the serial port when SP and DOIA are set to factory defaults.

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.

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.

To access the configuration from the web interface, follow these steps.

1. Make sure you have configured the Digi device with an IP address already. See Configure the

IPaddress.

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

URL window. The web interface log in screen displays.

3. Log in to the web interface using the default user name and password.

n User name: root

n Default password: The unique default password is printed on the label on the device. If

the password is not on the label, the default password is dbps. If neither password

works, the password may have been changed. Contact your system administrator.

Digi One Family and PortServer TS Family

Digi One Family and PortServer TSFamily Quick reference for configuring features

Download 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.

Quick reference for configuring features

This table is a quick reference for configuring features and performing device tasks, the Digi devices in which the features are supported, and where to find them in the web interface.

Some features are configurable from the command-line interface only. In those cases, the commands that configure the feature are noted. The command descriptions are in the Digi One and PortServer TS

Configure the IPaddress

The next step in configuring your Digi product 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 changing the IP address.

Before you begin

Before you configure your device server, write down the MAC Address located on the bottom of your product. For Digi One IA and Digi One SP products, the MAC address also serves as the serial number.

Options for configuring the IPaddress and mask

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

n From the command line, using the “set config” command. See Digi One and PortServer TS

Family Command Reference for more details including syntax and supported devices.

n By updating the ARP table on a server and then pinging the Digi device. This is called ARP-Ping.

See Configure the IP address using ARP-ing.

n Using a DHCP server. See Configure an IP Address using DHCP and RARP.

n Using a RARP server. See Configure an IP Address using DHCP and RARP.

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

address configuration.

Configure the IP address using ARP-ing

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

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.

This procedure assumes that your Digi device is connected to the Ethernet network.

1. Record the MAC address of the Digi device. The MAC address is on the label side (bottom) of the

unit.

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

Digi One Family and PortServer TS Family

Configure the IPaddress Configure an IP Address using DHCP and RARP

3. Manually update 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 191.168.2.2 00-00-9d-22-23-60

4. Ping the Digi device using the IP address just assigned. For example:

ping 191.168.2.2

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

5. Wait 30 seconds and then ping the Digi device again.

The Digi device replies to the ping, indicating that the IP address has been configured.

Configure an IP Address using DHCP and RARP

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

n DHCP Option 12: If the device is configured to use DHCP, the combined host and domain will

be sent as a hint to the DHCP server when requesting an IP address. As a convention, some

DHCP servers use this hint to assign the IP address associated with the host name.

n DHCP Option 81 FQDN (Fully Qualified Domain Name): If the device is configured to use

DHCP, and the FQDN option is enabled in the advanced settings menu, the device will send the

combined host and domain name as a request to the DHCP server to assign the IP address

associated with the host name.

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:

n Reserve a permanent IP address.

n Record the IP address. You will need it when you configure the RealPort driver.

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

Access the Digi device

Once an IP address is set, you can access its configuration and management web interface from a web browser.

Digi One Family and PortServer TS Family

Configure the IPaddress Access the Digi device

1. Enter the IP address in the URL bar of your browser. A web interface login screen displays.

2. Log in to the web interface. The Home page for the Digi device appears allowing you to

configure the device for your specific needs. A tutorial is available to guide you in your

decisions. The Help button in the upper right corner is also available.

3. Make any changes you need for your configuration.

4. Click Apply to save your changes.

5. Reboot when you are ready for the changes to take effect.

Digi One Family and PortServer TS Family

Configure network and serial ports

The next step in the device setup process is to configure the network and serial port settings, using the web interface for your Digi product.

Assumptions

To access the web interface, an IP address must be assigned to your Digi product. See Configure the

IPaddress. This chapter assumes that you have logged into the web interface using the default user

name and password.

n User name: root

n Default password: The unique default password is printed on the label on the device. If the

password is not on the label, the default password is dbps. If neither password works, the

password may have been changed. Contact your system administrator.

Network settings

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

Digi One Family and PortServer TS Family

Configure network and serial ports Network settings

2. Click DNS Settings.

n In the Name Servers fields, enter Primary, Secondary, and Teritiary DNS servers. The

DNS server maps names (example: MyDeviceName.mycompany.com) to IP addresses

(example:192.105.1.2).

n In the Domain field, enter the domain name that this device will live in that 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.

n In the Host Name field, enter a host name for a group of network devices.

3. Click Advanced Network Settings.

4. Enter the Base Socket. The base socket determines the network port (socket) on this Digi

terminal server that another network device (such as another Digi terminal server or a PC)

uses to communicate using the Digi device’s serial port services. These services include Telnet,

raw TCP/UDP, and SSL.

Most applications can leave this value unchanged. To calculate these settings:

n Telnet port = Base Socket + Serial Port Number

n Raw port = Base Socket + 100 + Serial Port Number

n SSL port = Base Socket + 600 + Serial Port Number

5. For example:

Service Base socket Network port

telnet 2000 2001

raw (TCP or UDP) 2000 2101

SSL 2000 2601

Port profiles

Each port profile determines the settings needed. Following are overviews of the port profiles and screen shots showing their settings. For more details about the port profile settings, click the Help link.

RealPort port profile

The RealPort profile configures the serial port to interoperate with the RealPort Driver hosted on a network-based PC. When RealPort is installed on a network-based PC, it emulates a serial port. That is, the application “thinks” it is working with a real serial port, such as COM1. When the application sends data to this serial port, RealPort encapsulates the data and ships it across the network to the Digi device 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.

With RealPort, SSL encryption is supported in network port 1027. Standard RealPort service is on network port 771. Both can be configured on the Advanced Network Settings page. To use SSL encryption, you must have a RealPort driver that supports SSL. For Unix and Linux, you can use one of these drivers: Linux, Solaris, AIX, SCO Openserver 5.x and 6, and HP-UX. With Windows, you can use the Win2k/Xp/2003 driver online, which supports Encrypted RealPort (OpenSSL/TLS1.0 128-bit AES).

A simple challenge/response MD5 hash authentication is also supported by the Windows driver on fs1.

Console Management port profile

Console Management involves accessing 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, cable the console port to the serial port of your Digi device. Then using Telnet features, network administrators can access these consoled serial ports from the LAN by addressing the appropriate TCP port.

Enabling port sharing

Under Console Management you can also enable port sharing. Port sharing allows multiple users to access the port at the same time. If port sharing is disabled, then only one user may access the port at a time. You may change the number of users at any time. If you increase the number of users from 2, the change takes effect immediately. If you decrease the number of users, the change does not

take effect until the users log off. For example, if port sharing is available for 9 with 9 users on, then changed to 2, the change will not take effect until at least 2 users log off. If port sharing is enabled for 2 and then disabled, the change will not take effect until everyone is off. The default value when port sharing is disabled is one.

Device and Driver Support for the Port Sharing Feature

n The port sharing feature and the set sharing command are supported in the following

products.

l All PortServer TS Family products.

l All Digi One products except Digi One IAP.

n The console menu feature and the Console Management port profile can be used to enable the

port sharing feature. The console menu feature and Console Manager port profile are available

on PortServer TS Family devices only. To configure port sharing for all other devices, use the

set sharing command.

n When used with RealPort, the port sharing feature is formally tested with the Windows

RealPort driver only, and not with Unix/Linux driver versions.

TCPSockets port profile

The Digi device supports TCP socket communication. 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 connections:

n Inbound connections, that is, connections that are initiated by the device on the other side of

the network.

n Outbound connection, that is, connections that are initiated by the device connected to the

serial port.

TCP Sockets profile is also the profile to use for Autoconnection. See Autoconnection.

UDPSockets port profile

The Digi device is capable of UDP multicast. UDP multicast is used to send serial data over an Ethernet cable to one or many hosts at the same time. UDP does not need a protocol because it sends data without any form of acknowledgment of error or error correction.

Configure network and serial ports Port profiles

The number of devices that can receive a UDP multicast varies by product.

n PortServer TS 8/16 Family: up to 16 devices can receive a UDP multicast at one time.

n All other products, including the Digi One Family and PortServer TS 1/2/4: 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 Digi device for the following types of connections:

n Inbound connections (UDPserver): Connections that are initiated by the device on the other

side of the network.

n Outbound connections (UDP client): Connections that are initiated by the device connected to

the serial port on the Digi device.

When you use UDPport profile, you are connecting a device with a serial port to the serial port on the Digi device. The serial parameters for both devices must match. For example, if the serial port for the device connected to the Digi device is set for 9600 bps, the serial port on the Digi device must also be set for 9600 bps.

Serial Bridging port profile

The Digi device supports serial bridging (sometimes referred to as ‘tunneling’). 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 with each other across a serial cable using serial communication
