Chapter 1 Introduction
8Chapter 1 Introduction
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 Ethernet interface,
which can be accomplished in a number of 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 that
will connect to the port and the peripheral’s cabling requirements.
See "Setting Up RealPort" on page 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 more information:
• "Setting Up RealPort" on page 35
• "Network Settings" on page 17
Chapter 1 Introduction 9
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 Security Features" on page 49
• "Special Features:Domain Name System (DNS)" on page 63
Supported Devices
This manual provides 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 PortServer 2/4 Wireless
• PortServer TS 8/16, PortServer TS 16 Rack, PortServer TS 16 DC
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 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.
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.
10 Chapter 1 Introduction
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.

12 Chapter 1 Introduction
Chapter 2 Configuring the IP Address 13
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 changing the IP address.
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 wizard automatically pops up for Microsoft Windows
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:
Chapter 2 Configuring the IP Address
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
14 Chapter 2 Configuring the IP Address
Configuring the IP Address with Digi Port Authority-Remote
Use this section to configure an initial IP address, subnet mask, and default
gateway using Digi Port Authority-Remote. This procedure cannot be used
to change the IP address, but only to assign the initial IP address. It also
cannot be used if a DHCP server is active.
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 Digi 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 address. If you do,
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 Authority-
Remote 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 need 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 Digi device is connected to the Ethernet network
Chapter 2 Configuring the IP Address 15
Procedure
1. Record the MAC address of the Digi device. The MAC address is on the
back of the unit.
2. Access a server on the same subnet as the Digi device.
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 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
RealPort driver.
2. Power on the device server.
The DHCP or RARP server assigns the device server an IP address.
Accessing the Digi Device
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
specific needs. A tutorial is available to guide you in your decisions. The Help
16 Chapter 2 Configuring the IP Address
button in the upper right corner is also available.
From the web interface, you make any changes you need for your
configuration. Remember to click Apply to save your changes and Reboot
when you are ready for the changes to take effect.
Chapter 3 Configuration 17
The next step in the device setup process is to configure the network and
serial port settings. In order to access the web interface an IP address
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.
Network Settings
1. Click Network to view the IP settings or make any changes to the IP
address.
2. Click Advance Network Settings.
Chapter 3 Configuration
18 Chapter 3 Configuration
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
Chapter 3 Configuration 19
6. Click Apply.
7. Click Reboot for changes to take effect.
Configuring the Serial Ports
1. Click Serial Ports under Configuration.
2. Click the port number that you want to configure.
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.
Service Base Socket Network Port
telnet 2000 2001
raw (TCP or UDP) 2000 2101
20 Chapter 3 Configuration
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.
Chapter 3 Configuration 21
Port Profiles
Each port profile determines the settings needed. The following
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, RealPort 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 ships 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, cable
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 LAN.
22 Chapter 3 Configuration
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 connections:
• Inbound connections, that is, connections that are initiated by the
device on the 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
Reboot for changes to take effect." on page 33 for more information.
UDP Sockets
The Digi TS Family devices are 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 is a ‘connectionless’ protocol, meaning UDP does not
need a protocol, but is sending data without 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 Digi
device for the following types of connections:
• Inbound connections, that is, connections that are initiated by the
device on the other side of the network.
• Outbound connection, that is, connections that are initiated by the
device connected to the serial port.
Chapter 3 Configuration 23
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 with 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 second Digi device server of the bridge specifying the
IP address of the first Digi device server.
24 Chapter 3 Configuration
Printer
This profile allows you to connect a printer to a serial port. Use this profile if
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.
Chapter 3 Configuration 25
Industrial Automation
The Industrial Automation (IA) Profile allows you to connect IA devices 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 information about Modem Emulation see "Special Features:
Modem Emulation" 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 Help button in the upper right corner on the profile
page of the web interface.
• Internal Modem
The Internal Modem profile (not listed in the graphic) is specific to
the PortServer TS 1/3+Modem devices. The fully functioning
26 Chapter 3 Configuration
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 and receives data over an Ethernet network instead
of a PSTN (Public Switched Telephone Network). The advantage for 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.
Chapter 3 Configuration 27
Power Management
The Power Controller feature allows the administrators of the Digi CM to
use console management to control power functions. 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
manually.
28 Chapter 3 Configuration
Custom
This profile allows you to see all settings and set them accordingly. Use this
profile only if your application does not fit into any of the predefined port
profiles.

Chapter 4 Setting Up RealPort 35
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.
About RealPort
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, which means they use all standard operating
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 system with which the 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
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.

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 advantage for 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.
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

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 replaces 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
44 Chapter 7 Special Features: Modem Emulation
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 transmission 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.

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 connection triggers the device server to generate a RING 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 require 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 connection.

In the following table, the Digi device server receives a request for a
connection.
Originating Calls
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
The TCP connection disconnects by either dropping the DTR signal on the
serial port or sending the escape sequence <P>+++<P> to the Digi device
server. <P> represents a one second pause.
Disconnecting Calls-Digi Device Server
The Digi device sends a NO CARRIER response to the serial port when
the network connection is dropped.

Rings to Auto-Answer
Sets the number of rings required before the
Digi Device Server automatically answers a
call. Setting this register to Zero disables auto-
answer mode.
0-255 Rings * 0
S1
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 sec-
ond interval.
0-255 Rings 0
S2
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.
0-255 ASCII * 43
S3
Carriage Return Character
Sets the command line and result code termi-
nator character. Pertains to asynchronous
operation only.
0-127 ASCII 13
S4
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.
0-127 ASCII 10
S5
Backspace Character
Sets the character recognized as a backspace.
Pertains to asynchronous operation only. The
modem will not recognize the Backspace char-
acter 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 trans-
mitted each time the modem processes the
Backspace character.

Chapter 8 Special Features: Power Over the Serial Ports 59
Serial Power Feature
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 available only through RI and only on
port one (1). The Serial Power feature is active on a specific port when that
port is configured for RS 232 operation.
• The power out budget equals one (1) watt (the total amount of
power available). The available power can be divided in any combi-
nation 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 both DTR and RI on the same port.
• Pinout information
— RI is pin 1
—DTR is pin 9
• RI signaling is lost when the pin is used for power
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 available using the RI pin. The Digi device requires
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.
Chapter 8 Special Features: Power Over the Serial
Ports
60 Chapter 8 Special Features: Power Over the Serial Ports
1. Open the device unit enclosure and move the black jumper to the
following settings:
P-6 jumper on pins 1 and 2
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 feature is one (1) watt not to exceed 5 volts @ 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 places: switch 1 and 3 are up
and 2 and 4 are down (see "Serial Power Table" on page 61 for
illustration).
2. Enable the RI power through the web interface.
3. Connect power supply with the barrel-connector power supply provided
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
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.
Configuring DTR Power
Power Out
Data Terminal Ready (DTR) power out is the factory default on the Digi
device server. Total power budget for this feature is one watt not to exceed
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.
Note: When the jumper is
placed correctly for
power in, the jumper w
ill
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.
Chapter 8 Special Features: Power Over the Serial Ports 61
2. Open the port and set DTR high.
If you are having 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 Administration 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.

Chapter 9 Special Features: IA (Industrial Automation) 63
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 elements of communication between devices that are defined
by the Modbus protocol include:
• The structure of Modbus messages
• How the master requests information from the slave or specifies an
action for the slave to take
• How the slave is to respond
• Addressing conventions
• Handling of many of the other details required for communication to
occur.
Modbus defines two encoding schemes: Modbus ASCII and Modbus RTU.
Each Modbus device uses one or the other.
Designed to function over a serial communication cable, Modbus has been
extended in recent years to function 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 network-based masters to concurrently
initiate communication with serial-based slaves using any of the supported
network protocols.
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 best 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,
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
Chapter 9 Special Features: IA (Industrial
Automation)
64 Chapter 9 Special Features: IA (Industrial Automation)
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 Special Features: SNMP 65
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 device 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.
• One or more network managers (also called network management
stations), which are the points from which the network is managed
• Agents that reside on managed nodes and retrieve management
information and communicate this information to network managers.
• The network management protocol, SNMP, which governs the
exchange of information 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 defined by SNMP is called a trap, which is a report or “alarm”
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
66 Chapter 10 Special Features: SNMP
• Read-write for MIB II (RFC 1213), which is an Internet-standard
MIB, consisting of managed objects from the systems, interfaces, IP,
ICMP, TCP, UDP, transmission, and SNMP group
• Read-write for the character-stream devices using 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 (device server initializes)
• 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.

Rack Mounting Installation (PortServer TS 16 Rack and DC Rack)
• Distribute weight evenly in the rack to avoid overloading.
• Ensure proper ventilation with at least 12 inches (30 centimeters) of
clearance on all sides.
• Check equipment nameplate ratings before connecting to the supply
circuit to avoid overloads which may damage over-current protection
devices and supply wiring.
• Maintain reliable earthing for rack-mounting equipment, especially
for supply connections.
• Install equipment in Restricted Access Areas only (dedicated
equipment rooms/closets) in accordance with Articles 110-16,
110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.
• Connect equipment to a DC supply source (reliably earthed) that is
electrically isolated from the AC source.
• Directly connect the equipment chassis to the DC supply system-
grounding electrode conductor or a bonding jumper from a
grounding terminal bar (or bus) that is connected to the DC supply
system grounding electrode conductor.
• Contain equipment that has a connection between the grounded
conductor of the same DC supply circuit, the grounding conductor,
and also the point of grounding of the DC system in the same
immediate area. Do not ground the equipment elsewhere.
• Locate the DC supply source within the same premises as the
equipment.
• Route away and secure all DC input wiring from sharp edges to
prevent chaffing as well as provide strain relief.
Provide a readily accessible disconnect device and protective device a
fixed wiring for a DC power supply suitable for the specified rated voltage
and current. Disconnect and protective devices to be rated 2A Amps
maximum.

must be used to avoid electrical shock from such facilities. You must
avoid contact with all such facilities.
• Telephone wiring must be at least 6 feet from bare power wiring or
lightning rods and associated wires, and at least 6 inches from other
wire (antenna wires, doorbell wires, wires from transformers to neon
signs), steam or hot water pipes, and heating ducts.
• Before working with existing inside wiring, check all electrical outlets
for a square telephone dial light transformer and unplug it from the
electrical outlet. Failure to unplug all telephone transformers can
cause electrical shock.
• Do not place a jack where it would allow a person to use the
telephone while in a bathtub, shower, swimming pool, or similar
hazardous location.
• Protectors and grounding wire placed by the service provider must
not be connected to, removed, or modified by the customer.
