Features Features This is an overview of key features in Digi devices. Firmware features are covered in more detail in the next three chapters. Hardware specifications are covered in Chapter 7, "Specifications and certifications". User interfaces There are several user interfaces for configuring and monitoring Digi devices, including the following. Some of these user interfaces can be customized.
Features IP protocol support All Digi devices include a Robust on-board TCP/IP stack with a built-in web server.
Features Serial data communication over TCP and UDP Digi devices support serial data communication over TCP and UDP. Key features include: Serial data communication over TCP, also known as autoconnect and tcpserial can automatically perform the following functions: – Establish bidirectional TCP connections, known as autoconnections, between the serial device and a server or other network device. Autoconnections can be made based on data and or serial hardware signals.
Features Simple Network Management Protocol (SNMP) Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network devices. SNMP architecture enables a network administrator to manage nodes--servers, workstations, routers, switches, hubs, etc.--on an IP network; manage network performance, find and solve network problems, and plan for network growth. Digi devices support SNMP Versions 1 and 2.
Features Point-to-Point Protocol (PPP) The Point-to-Point Protocol (PPP) transports multi-protocol packets over point-to-point links. PPP encapsulates the data packet, allows the server to inform the dial-up client of its IP address (or client to request the IP address), authenticates the exchange, negotiates multiple protocols, and reassembles the data packet for network communication.
Features RealPort software Digi devices use the patented RealPort COM/TTY port redirection for Microsoft Windows, UNIX, and Linux environments. RealPort software provides a virtual connection to serial devices, no matter where they reside on the network. The software is installed directly on the host PC and allows applications to talk to devices across a network as though the devices were directly attached to the host. Actually, the devices are connected to a Digi device somewhere on the network.
Features Alarms Digi devices can be configured to issue alarms, in the form of email message or SNMP traps, when certain device events occur. These events include changes in GPIO signals, certain data patterns being detected in the data stream,. Receiving alarms about these conditions provides the advantage of notifications being issued when events occur, rather than having to monitor the device on an ongoing basis to determine whether these events have occurred.
Features Security features in Digi devices Secure access and authentication One password, one permission level. Passwords can be issued to device users. Selective enabling/disabling network services such as ADDP, RealPort, Encrypted RealPort, HTTP/HTTPS, LPD, Remote Login, Remote Shell, SNMP, and Telnet. Can control access to inbound ports. Can control access to specific devices, IP addresses, or networks through IP filtering.
Features SNMP security SNMP “set” commands can be disabled to make use of SNMP read-only. Changing public and private community names is recommended to prevent unauthorized access to the device.
Supported connections and data paths in Digi devices Supported connections and data paths in Digi devices Digi devices allow for several kinds of connections and paths for data flow between the Digi device and other entities. These connections can be grouped into two main categories: Network services, in which a remote entity initiates a connection to a Digi device. Network/serial clients, in which a Digi device initiates a network connection or opens a serial port for communication.
Supported connections and data paths in Digi devices Network services associated with serial ports in general RealPort: A single TCP connection manages (potentially) multiple serial ports. Modem emulation, also known as pseudo-modem (pool): A TCP connection to the “pool” port is interpreted as an incoming call to an available pseudo-modem in the “pool” of available port numbers.
Supported connections and data paths in Digi devices Network/serial clients A network/serial client connection is one in which a Digi device initiates a network connection or opens a serial port for communication.
Interfaces for configuring, monitoring, and administering Digi devices Interfaces for configuring, monitoring, and administering Digi devices There are several interfaces for configuring, monitoring, and administering Digi devices. These interfaces are covered in more detail later in this guide.
Interfaces for configuring, monitoring, and administering Digi devices Configuration interfaces Several interfaces are available for configuring Digi devices, including: The Digi Device Setup Wizard, which helps set up an IP address for the device and quickly configure features. The Digi Device Discovery Utility, which locates Digi devices on a network, and allows opening the web interface for the devices. Device Management, a configuration interface to fine-tune or monitor devices.
Interfaces for configuring, monitoring, and administering Digi devices For most users, the Digi Device Setup Wizard interface provides adequate device configuration. Device configuration is made easier by providing a set of port profiles which configure a serial port based on the way the port will be used. Each port profile displays the relevant settings for the configuration.
Interfaces for configuring, monitoring, and administering Digi devices Digi Device Discovery utility The Digi Device Discovery utility locates Digi devices on a network and allows for opening the web interface for discovered devices, configuring network settings, and rebooting the device.
Interfaces for configuring, monitoring, and administering Digi devices Device Management™ interface Device Management is a software-as-a-service, delivering capabilities that empower IT, network operations and customer support organizations to conquer the challenges of managing the vast array of equipment in their device networks. As a network grows, the complexity of effectively managing the network assets grows exponentially.
Interfaces for configuring, monitoring, and administering Digi devices With Device Management, management of large populations of devices is made easy. Devices can be tagged and grouped together enabling management tasks to groups of devices within a network simultaneously. Furthermore, the Scheduled Operations feature allows device management tasks to be automated and scheduled to run either on a one-time or a recurring basis, against a single device or multiple devices.
Interfaces for configuring, monitoring, and administering Digi devices Web interface A web interface is provided as an easy way to configure and monitor Digi devices. Configurable features are grouped into several categories. These categories vary by product; examples include Network, Serial Port, Alarms, and System. Most of the configurable features are arranged by most basic settings on a page, with associated and advanced settings accessible from that page.
Interfaces for configuring, monitoring, and administering Digi devices Java applet interface An alternative configuration interface is provided with Digi Connect Family products, in the form of a Java applet. This interface provides many, but not all, of the configuration choices available through the web interface. The Java applet is primarily intended as a sample alternative interface for embedded products. Embedded product manufacturers can use the applet as a base for their custom user interface.
Interfaces for configuring, monitoring, and administering Digi devices The Java applet can also be used as a basis for further interface development. That is, if the Java applet is adequate for most configuration needs, but needs some modifications, the applet’s operation can be customized. If a totally unique user interface is desired, the Java applet can serve as a sample program and a starting point from which to build new interfaces.
Interfaces for configuring, monitoring, and administering Digi devices Command-line interface Digi devices can be configured by issuing commands from the command line. The command-line interface allows communication directly without a graphical interface. To access the command line from the Digi Device Discovery utility, click Telnet to command line.
Interfaces for configuring, monitoring, and administering Digi devices Simple Network Management Protocol (SNMP) Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network devices. The SNMP architecture enables a network administrator to manage nodes-servers, workstations, routers, switches, hubs, etc.--on an IP network; manage network performance, find and solve network problems, and plan for network growth. Digi devices support SNMP Versions 1 and 2.
Interfaces for configuring, monitoring, and administering Digi devices Monitoring capabilities and interfaces Monitoring Digi devices includes such tasks as checking device status, viewing information on a device’s GPIO pins, checking runtime state, viewing serial port operations, and reviewing network statistics, and managing their connections. There are several interfaces for monitoring Digi devices and managing their connections.
Interfaces for configuring, monitoring, and administering Digi devices Device administration Periodically, administrative tasks need to be performed on Digi devices, such as uploading and managing files, changing the password for logging onto the device, backing up and restoring device configurations, updating firmware, restoring the configuration to factory defaults, and rebooting.

To ensure proper ventilation and air flow for units, provide at least 12 inches (30 centimeters) of clearance on all sides for each unit. Distribute weight evenly in the rack to avoid overloading.
Configuration C H A P T E R 3 This chapter describes how to configure a Digi device. It covers these topics: "IP address assignment" on page 42 "Configuration through Device Management" on page 45 "Configuration through the Digi Device Setup Wizard" on page 46.
IP address assignment IP address assignment Default IP address and DHCP settings All products that have a cellular (WAN) interface ship with static IP address for the Ethernet port of 192.168.1.1 and DHCP server enabled by default. The Ethernet port of the laptop should be configured to automatically receive an IP address and DNS server address. All products that only have an Ethernet or Wi-Fi (LAN) interface ship with DHCP client enabled by default.
IP address assignment Assign an IP address using the Digi Device Setup Wizard The Digi Device Setup Wizard is included on the Software and Documentation CD for your product. Using this wizard is the easiest way to assign an IP address and initially configure Digi devices. It discovers Digi devices on a network, configures an IP address for a Digi device, and configures basic serial port parameters according to how the device will be used.
IP address assignment Configure an IP address using Auto-IP The standard protocol Automatic Private IP Addressing (APIPA or Auto-IP) automatically assigns the IP address from a group of reserved IP addresses to the device on which Auto-IP is installed. Use Digi Device Discovery or DHCP to find the Digi device and assign it a new IP address that is compatible with your network. Once the unit is plugged in, Auto-IP automatically assigns the IP address. Auto-IP addresses are typically in the 169.254.x.
Configuration through Device Management Configuration through Device Management Device Management is an on-demand service. After creating a Device Cloud account, you can connect to Device Management. There are no infrastructure requirements. Remote devices and enterprise business applications connect to Device Management via standards-based Web Services.
Configuration through the Digi Device Setup Wizard Configuration through the Digi Device Setup Wizard The Digi Device Setup Wizard configures Digi devices according to one of several port profiles, or configuration scenarios that characterize the manner in which the Digi device will be used. Depending on the Digi device, the wizard configures several other features. To run the wizard, insert the Software & Documentation CD packaged with your Digi device in your computer’s CD/ DVD drive.
Configuration through the Digi Device Setup Wizard Verify configuration settings On the Verify Configuration screen, clicking Next shows the configuration settings that will be uploaded to the Digi device. Save settings The Save Settings page is displayed while the configuration settings are uploaded to the Digi device. Other messages and wizards may be displayed during this step; click OK on message boxes and Next on wizard screens to continue the installation process.
Configuration through the web interface Configuration through the web interface Open the web interface To open the web interface, either enter the Digi device’s URL in a web browser and log on to the device, if required, or use the Digi Device Discovery utility to locate it and open its web interface. By entering the Digi device’s IP address in a web browser 1 In the URL address bar of a web browser, enter the IP address of the device.

Depending on whether a system administrator has configured password authentication for the device, a login may be required.
Configuration through the web interface Organization of the web interface The Home page When the web interface is opened, the Home page is displayed. Here is the Home page for Digi Connect ME The left side of the Home page has a menu of choices that display pages for configuration, management, and administration tasks, and to log out of the web interface. This chapter focuses on the choices under Configuration and Applications.
Configuration through the web interface Configuration pages The choices under Configuration in the menu display pages for configuring settings for various features, such as network settings, and serial port settings. Some of the configuration settings are organized on sets of linked screens. For example, the Network Configuration screen initially displays the IP Settings, and provides links to Network Services Settings, Advanced Settings, and other network settings appropriate to the Digi device.
Configuration through the web interface Change the IP address from the web interface, as needed Normally, IP addresses are assigned to Digi devices either through DHCP or the Digi Device Setup Wizard. This procedure assumes that the Digi device already has an IP address and you simply want to change it. 1 Open a web browser and enter the Digi device’s current IP address in the URL address bar. 2 If security is enabled for the Digi device, a login prompt is displayed.
Configuration through the web interface Network configuration settings The Network configuration pages include: Ethernet IP settings: For viewing IP address settings and changing as needed. See page 56. WiFi IP settings: For setting the IP address used for wireless LAN communication. See page 60. WiFi LAN settings: For setting basic options for wireless LAN devices such as network name and network connection options. See page 60.
Configuration through the web interface Alternatives for configuring network communications There are three ways a Digi device can be configured on the network. Using dynamic settings: All network settings will be assigned automatically by the network, using a protocol called DHCP. Contact your network administrator to find out if a DHCP server is available. Using static settings: All network settings are set manually and will not change. The IP address and subnet mask are mandatory.
Configuration through the web interface Ethernet IP settings or Ethernet Switch IP Settings Ethernet Uplink IP Settings (for Digi Connect ES 4/8 SB with Switch) The Ethernet IP Settings page configure how the IP address of the Digi device is obtained, either by DHCP or by using a static IP address, subnet mask, and default gateway. For more information about how these settings are assigned and used in your organization, contact your network administrator.
Configuration through the web interface Ethernet IP Settings (for Digi Connect ES 4/8 SB with Switch only) This section describes configuring and deploying Digi Connect ES4/8 SB with Switch devices in a network. The Digi Connect ES4/8 SB with Switch has two Ethernet interfaces: Ethernet Uplink: An uplink interface, that connects to the central data management system network.
Configuration through the web interface Assuming the network topology just described, here are the steps for configuring the Ethernet interfaces of each Digi Connect ES 4/8 SB with Switch device for installation. These steps apply to a single Digi Connect ES 4/8 SB with Switch and its connected Ethernet and serial devices, and must be performed for each Digi Connect ES 4/8 SB with Switch deployed.
Configuration through the web interface Deploy the Digi Connect ES 4/8 SB with Switch To deploy the Digi Connect ES 4/8 SB with Switch after network configuration: 1 Install the Digi Connect ES 4/8 SB with Switch in the desired location. 2 Connect the Digi Connect ES 4/8 SB with Switch to the main/business Ethernet network through the Ethernet Uplink connection, using a straight-through Ethernet cable. 3 Connect the network devices to the Ethernet Switch ports, using straight-through Ethernet cables.
Configuration through the web interface WiFi IP settings The WiFi IP settings configure how the IP address of a Wi-Fi-enabled Digi device is obtained. It has the same settings as the Ethernet IP settings page. WiFi LAN settings Digi devices with Wi-Fi (wireless LAN) capability contain a wireless network interface that may be used to communicate to wireless networks using 802.11b8 technology.
Configuration through the web interface WiFi security settings The WiFi security settings specify the wireless security settings that the wireless network uses. Multiple security and authentication modes may be chosen depending on the configuration of the access point or wireless network. The wireless device will automatically select and determine the authentication and encryption methods to use while associating to the wireless network.
Configuration through the web interface Data Encryption: Multiple encryption methods can be selected. – Use any available encryption method: enables all of the methods. The actual method used will be determined by the capabilities of the wireless network. – Use the following selected method(s): Selects one or more encryption methods. Open System: No encryption is used over the wireless link. Open System encryption is valid only with Open System and Shared Key authentication.
Configuration through the web interface WiFi 802.1x authentication settings These settings are not required based on the current Wi-Fi authentication settings. They are only configurable when WEP with 802.1x authentication or WPA with 802.1x authentication are enabled on the WiFi Security Settings tab. EAP Methods: These are the types of Extensible Authentication Protocols (EAP) or outer protocols that are allowed to establish the initial connection with an authentication server or access point.
Configuration through the web interface Network services settings The Network Services page shows a set of common network services that are available for Digi devices, and the network port on which the service is running. Common network services can be enabled and disabled, and the TCP port on which the network service listens can be configured. Disabling services may be done for security purposes. That is, certain services can be disabled so the device runs only those services specifically needed.
Configuration through the web interface Service Services provided Default network port number Device Discovery, also known as Advanced Digi Discovery Protocol (ADDP) Discovery of Digi devices on a network. Disabling this service disables use of the Digi Device Discovery utility to locate the device, either on its own or as part of running the Digi Device Setup Wizard. The network port number for ADDP cannot be changed from its default.
Configuration through the web interface Service Services provided Default network port number Telnet Server Allows users an interactive Telnet session to the Digi device’s command-line interface. If disabled, users cannot Telnet to the device. 23 Telnet Passthrough Allows a Telnet connection directly to the serial port, often referred to as reverse Telnet. 2001 Transmission Control Protocol (TCP) Echo Used for testing the ability to send and receive over a TCP connection, similar to a ping.
Configuration through the web interface IP filtering settings You can better restrict your device on the network by only allowing certain devices or networks to connect. This is better known as IP Filtering or Access Control Lists (ACL). By enabling IP filtering, you are telling the device to only accept connections from specific and known IP addresses or networks.
Configuration through the web interface IP forwarding settings When a Digi device acts as a router and communicates on both a private and public network with different interfaces, it is sometimes necessary to forward certain connections to other devices. This is also known as Network Address Translation (NAT) or Port Forwarding. When an incoming connection is made to the device on the private network, the IP port is searched for in the table of port forwarding entries.
Configuration through the web interface – Enable DMZ Forwarding to this IP address: DMZ Forwarding allows you to specify a single host (DMZ Server) on the private (internal) network that is available to anyone with access to the NAT Public Interface IP address, for any TCP- and UDP-based services that haven't been configured. Services enabled directly on the Digi device take precedence over (are not overridden by) DMZ Forwarding.
Configuration through the web interface – Forward TCP/UDP/FTP connections from external networks to the following internal devices: Specifies a list of connections based on a specific IP port and where those connections should be forwarded to. Typically the connecting devices come from the public side of the network and are redirected to a device on the private side of the network. It is possible to forward a single port or a range of ports.
Configuration through the web interface Socket tunnel settings A Socket Tunnel can be used to connect two network devices: one on the Digi device’s local network and the other on the remote network. This is especially useful for providing SSL data protection when the local devices do not support the SSL protocol. One of the endpoint devices is configured to initiate the socket tunnel. The tunnel is initiated when that device opens a TCP socket to the Digi device device on the configured port number.
Configuration through the web interface Advanced network settings The Advanced Network Settings are used to further define the network interface. These settings rarely need to be changed. Contact your network administrator for more information about these settings. IP Settings The IP settings are used to fine-tune IP address configuration. Host Name: The host name to be placed in the DHCP Option 12 field. This is an optional setting which is only used when DHCP is enabled.
Configuration through the web interface Ethernet Interface Speed: The Ethernet speed the Digi device uses on the Ethernet network. – 10: The device operates at 10 megabits per second (Mbps) only. – 100: The device operates at 100 Mbps only. – auto: The device senses the Ethernet speed of the network and adjusts automatically. The default is auto. If one side of the Ethernet connection is using auto (negotiating), the other side can set the Ethernet speed to whatever value is desired.
Configuration through the web interface Serial port settings The Serial Port Configuration page is used to establish a port profile for the serial port of the Digi device. The Serial Port Configuration page includes the currently selected port profile for the serial port, detailed configuration settings for the serial port, dependent on the port profile selected, and links to basic and advanced serial settings.
Configuration through the web interface RealPort profile The RealPort profile maps a COM or TTY port to a serial port. This profile configures a Digi device to create a virtual COM port on a PC, known as COM Port Redirection. The PC applications send data to this virtual COM port and RealPort sends the data across the network to the Digi device. Data is routed to the serial device connected to the Digi device’s serial port. The network is transparent to both the application and the serial device.
Configuration through the web interface TCP Sockets profile The TCP Sockets profile allows serial devices to communicate over a TCP network. The TCP Server allows other network devices to initiate a TCP connection to the serial device attached to the serial port of the Digi device. Automatic TCP connections (autoconnection) The TCP Client allows the Digi device to automatically establish a TCP connection to an application or a network, known as autoconnection.
Configuration through the web interface UDP Sockets profile The UDP Sockets profile allows serial devices to communicate using UDP. The UDP Server configuration allows the serial port to receive data from one or more systems or devices on the network. The UDP Client configuration allows the automatic distribution of serial data from one host to many devices at the same time using UDP sockets. The port numbering conventions shown in the TCP Sockets Profile also apply to UDP sockets.
Configuration through the web interface Modem Emulation profile The Modem Emulation profile allows a Digi device to sends and receive modem responses to the serial device over the Ethernet instead of PSTN (Public Switched Telephone Network). This profile allows maintaining the current software application but using it over a less-expensive Ethernet network. The commands that can be issued in a modem-emulation configuration are described in the Digi Connect Family Command Reference.
Configuration through the web interface Basic serial settings After selecting a port profile, the profile settings are displayed. Choose the appropriate features for your environment. Here are brief descriptions of the fields in the Basic Serial Settings; see the online help for detailed information about each setting. The Description field specifies an optional character string for the port which can be used to identify the device connected to the port.
Configuration through the web interface Advanced serial settings The advanced serial settings further define the serial interface, including whether port buffering (also known as port logging), RTS Toggle, and RCI over Serial are enabled as general serial interface options. You can also define how specific aspects of TCP and UDP serial communications should operate, including timeouts and whether a socket ID is sent.
Configuration through the web interface TCP settings The TCP Settings are displayed only when the current serial port is configured with the TCP Sockets or the Custom Profile.The settings are as follows: Send Socket ID: Include an optional identifier string with the data sent over the network. The Socket ID can be 1 to 256 ASCII characters.
Configuration through the web interface Close connection after the following number of idle seconds: Enable to close an idle connection. Use the Timeout field to enter the number of seconds that the connection will be idle before it is closed. This can be 1 to 65000 seconds. Close connection when DCD goes low: When selected, the connection will be closed when the DCD (Data Carrier Detected) signal goes low.
Configuration through the web interface GPIO pins All Digi Connect Family devices except Digi Connect SP and Digi Connect Wi-SP have several General Purpose IO (GPIO) pins. In normal operation, GPIO pins are used for the serial signals CTS, DCD, DSR, DTR, and RTS. On Digi Connect EM and Wi-EM, both sets of RXD/TXD signals are also configured. These GPIO pins can be used for either standard serial communication signalling or a user-defined purpose, such as when a significant event occurs in the device.
Configuration through the web interface Out: Allows output of GPIO signals. The GPIO pin is used for user-defined signal output from the Digi device to the connected device. This mode can be used to toggle the output of GPIO signals between high and low.
Configuration through the web interface Alarms The Alarms page is for configuring device alarms and displaying alarm settings. Device alarms are used to send email messages or SNMP traps when certain device events occur.
Configuration through the web interface Alarm conditions The Alarm Conditions part of the Alarms page shows a list of all of the alarms. Up to 32 alarms can be configured for a Digi device, and they can be enabled and disabled individually. Alarm list and status The alarm list displays the current status of each alarm. This list can be used to list to view alarm status at a glance, then view more details for each alarm as needed.
Configuration through the web interface Alarm configuration To configure an alarm, click on it. The configuration page for individual alarms has two sections. Alarm conditions For specifying the conditions on which the alarm is based, such as GPIO pin state changes, serial data pattern matching, signal strength (RSSI), or data usage. Alarm conditions include: Send alarms based on GPIO pin states: Click this radio button to specify that this alarm is sent when the specified GPIO pin states are detected.
Configuration through the web interface Alarm destinations Alarm Destinations defines how alarm notifications are sent, either as an email message or an SNMP trap, or both, and where the alarm notification is sent. Send E-mail to the following recipients when alarm occurs: Select the checkbox to specify that the alarm should be sent as an email message. Then specify the following information: – To: The email address to which this alarm notification email message will be sent.
Configuration through the web interface System settings The System Configuration page configures device identity and description information, date and time settings, and settings for Simple Network Management Protocol (SNMP). Device identity settings The device identity settings create a description of the Digi device’s name, contact, and location. This information can be useful for identifying a specific Digi device when working with a large number of devices in multiple locations.
Configuration through the web interface Date and Time settings The Date and Time settings set the Coordinated Universal Time (UTC) and/or system time and date on a device, or sets the offset from UTC for the device's system time. Set Date and Time Click the Set button to configure the hours, minutes, seconds, month, day, and year on the device. If offset is set to 00:00, the device's system time and UTC are the same.
Configuration through the web interface Time Source Settings The time source settings configure access to up to five external time sources that can be used to set and maintain time on the device. Type: Specifies the type of time source for this entry. – sntp server: The device uses its SNTP client to poll the NTP/SNTP server, specified by the FQDN, for time. – cellular: The device polls the cellular service for time. Interval: Specifies the interval in seconds between polls of a time source.
Configuration through the web interface Time Source Global Settings The Time Source Global settings configures global settings that control time source management. Time Adjustment Threshold: a value in seconds that defines a range around the current time value maintained by the device. If a time update is received from a best (smallest value) ranking time source and the new time is within that range, the device's time is not changed.
Configuration through the web interface Simple Network Management Protocol (SNMP) Simple Network Management Protocol (SNMP) is a protocol that can be used to manage and monitor network devices. Digi devices can be configured to use SNMP features, or SNMP can be disabled entirely for security reasons. To configure SNMP settings, click the Simple Network Management Protocol link at the bottom of the System Configuration page.

Configuration through the web interface Device Cloud settings Note In this discussion: – The term Device Cloud refers to the Etherios machine-to-machine cloud-based network operating platform. – Device Management refers to a web based device management application that allows a user to manage their inventory of iDig devices. – Device Cloud-registered device is device that connects to the Device Cloud platform which implements the EDP protocol in order to establish and maintain this connection.
Configuration through the web interface Connection settings The Connection settings configure how the Device Cloud-registered device connects to Device Cloud. These settings include information about communication between the Device Cloudregistered device and Device Cloud, and the connection methods used by the various interfaces on the device.
Configuration through the web interface A timed connection is another form of a device-initiated connection. For a timed connection, the Device Cloud-registered device attempts to connect to the Device Cloud Server at a configured, regular interval (period). If a connection to an Device Cloud Server is already established, the timed connection will not be attempted. The next attempt for a timed connection will occur at the next scheduled interval.
Configuration through the web interface Retry if the IP address update fails: Retry after: These options specify whether another IP address update attempt should be made after a previous attempt failed, and how often the retry attempts should occur. Timed Device Cloud Connection Enable Timed Device Cloud Connection: When enabled, this device will initiate the connection to the Device Cloud Server at the configured interval (period).
Configuration through the web interface Paged Device Cloud Connection settings Enable Paged Device Cloud Connection: When enabled and a request is received to do so, the Device Cloud-registered device will initiate the connection to Device Cloud. A paged connection is initiated on demand when a request to connect is received from an external communication, such as a Short Message received via a mobile service provider.
Configuration through the web interface Advanced Device Cloud settings The default settings for Device Cloud remote management usually work for most situations. The Advanced settings configure the idle timeout for the connection between the Device Cloudregistered device and Device Cloud, and the keep-alive settings of the various interfaces (TCP and HTTP for mobile and Ethernet network connections). These settings should only be changed when the defaults do not properly work.
Configuration through the web interface Server Send Interval: Specifies how frequently the Device Cloud-registered device sends a keep-alive packet to Device Cloud if the Device Cloud connection is idle. Device Cloud expects to receive either Device Cloud protocol messages or keep-alive packets from the Device Cloud-registered device at this interval. Important: It is recommended that this interval value be set as long as your application can tolerate to reduce the amount of data traffic.
Configuration through the web interface Manually configure a Device Cloud-registered device to connect to Device Cloud To use Device Management as a device manager for your Device Cloud-registered device, you need to manually configure the device to connect to Device Cloud. 1 Open the web interface for the Device Cloud device and go to Configuration > Device Cloud. 2 On the Device Cloud Configuration settings page, enter the URL of the Device Cloud platform, for example, login.etherios.
Configuration through the web interface Managing alarms through Device Cloud All alarms can be sent to Device Cloud for display and management from that interface. See "Alarms" on page 85. Users settings Users settings involve several areas: User authentication: whether authentication is required for users accessing the Digi device, and the information required to access it.Depending on the Digi product, multiple users and their authentication information can be defined.
Configuration through the web interface Two-user model User 1 has a default name of root. This user is also known as the administrative user. User 1 has default permissions that enables it to issue all commands. Permissions for User 1 can be changed to be less than the default root permissions. User 2 is undefined. That is, it does not exist by default, but it can be defined.
Configuration through the web interface Password authentication By default, Digi Connect Family devices have password authentication enabled. That means when a login prompt is displayed when accessing the device by opening the web interface or issuing a telnet command. Disable password authentication Password authentication can be disabled as needed. In the web interface: 1 On the Main menu, click Users. 2 On the Users Configuration page, check the Enable password authentication check box.
Configuration through the web interface Change the password for administrative user To increase security, change the password for the administrative user from its default. By default, the administrative username is root. Note Record the new password. If the changed password is lost, the Digi device must be reset to the default firmware settings. In Digi devices with a single-user model, changing the root password also changes the password for Advanced Digi Discovery Protocol (ADDP).
Configuration through the web interface Add users Digi devices allow multiple users to be defined. For those products, the Users Configuration page shows the currently defined users and allows you to add more user definitions. To add a user definition: 1 On the Main menu, click Users. 2 On the Users Configuration page, click New. 3 On the Add New Users page, specify the user name and password to be used for login. The password can be from 4 through 16 characters long and is case-sensitive.
Configuration through the web interface User permissions settings The User Permissions page is used to define whether and how users can use services and configuration settings for the Digi device. For example, you can disable a user’s access to certain parts of the web interface, or allow them to display settings only but not change them. The list of services and the user permissions available for them vary by Digi device and the features supported in the product.
Configuration through the web interface User permissions and effects Permission Setting Effect None The user will not have permission to execute this setting. Read Self The user will be able to display their own settings, but not those of other users. Read The user has permission to read the setting for all users, but does not have permission to modify or write the setting. Read/Write Self The user has permission to read and write their own setting, but not those of other users.
Configuration through the web interface Additional ways to control user access Disable unused and non-secure network services To further secure the Digi device, network services not necessary to the device, particularly nonsecure or un-encrypted network services such as Telnet, can be disabled.

Administration from the web interface Device administration C H A P T E R 5 This chapter discusses the administration tasks that need to be performed on Digi devices periodically, such as file management, changing the password used for logging onto the device, backing up and restoring device configurations, updating firmware and Boot/POST code, restoring the device configuration to factory defaults, and rebooting the device.
Administration from the web interface File management The File Management page of the web interface uploads custom files to a Digi device, such as the files for a custom applet, or a custom image file of your company logo. Custom applets allow the flexibility to alter the interface either by adding a different company logo, changing colors, or moving information to different locations. If custom applets or the sample Java applet is not used, using this feature is not necessary.
Administration from the web interface Backup/restore device configurations Once a Digi device is configured, backing up the configuration settings is recommended in case problems occur later, firmware is upgraded, or hardware is added. If multiple devices need to be configured, the backup/restore feature can be used as a convenience, where the first device’s configuration settings is backed up to a file, then the file is loaded onto the other devices.
Administration from the web interface Update firmware and Boot/POST Code The firmware and/or boot/POST code for a Digi device can be updated from a file on a PC or through TFTP. The recommended method is to download the firmware to a local hard drive. TFTP is supported for those using UNIX systems. Both the firmware and the boot/POST code are updated using the same set of steps.The Digi device automatically determines the type of image being uploaded.
Administration from the web interface Restore a device configuration to factory defaults There are several ways to reset the device configuration of a Digi device to the factory default settings: using the Administration > Factory Defaults page in the web interface; using the boot command from the command line; and using the Reset button, or, on some models, a Reset signal The first two reset methods are a soft reset, while the reset button/signal method is a hard reset.
Administration from the web interface Using the Reset button If the Digi device cannot be accessed from the web interface, the configuration can be restored to factory defaults by using the Reset button.This kind of reset clears all configuration settings. 1 Power off the Digi device. 2 Locate the Reset button or pin on your device.Here is the reset button for a Digi Connect SP unit.
Administration from the web interface 3 Hold the Reset button down gently with a non-conductive, small diameter tool (such as wood or plastic) with a blunt end (NOT SHARP or the button could be damaged). Power on the device while holding the Reset button down. On some models, after a few seconds you may see the Status LED blink a 1-1-1 pattern once. For Digi Connect ME and Digi Connect Wi-ME, short pin 20 (the /init pin) to ground during boot up to restore the module to factory defaults.
Administration from the web interface Display system information System information displays the model, MAC address, firmware version, boot version, and POST version of the Digi device. It also displays memory available: total, used, and free, and tracks CPU percent utilization and the uptime. From the web interface menu, select Administration > System Information. Select General, GPIO, Serial, Network, or Diagnostics for the appropriate information.
Administration from the Java applet interface Administration from the Java applet interface In the Java applet device interface, administration tasks are also organized under Administration in the main menu. There are fewer choices than in the web interface: Backup/Restore: Backs up or restores a Digi device configuration. Restore Factory Defaults: Restores a Digi device’s configuration to factory defaults.
Administration from the Java applet interface Restore device configuration to factory defaults There are two ways to restore the device configuration to the factory default settings: Reset the configuration from a web browser, which clears all current device configuration settings except the IP address settings and administrator password.
Administration from the command-line interface Administration from the command-line interface Administrative tasks for Digi devices can also be performed from the command line. Here are several device-administration tasks and the commands used to perform them. See the Digi Connect Family Command Reference for more complete command descriptions. For descriptions of these commands, see the Digi Connect Family Command Reference.
Latency Tuning Latency Tuning C H A P T E R 6 What is Latency? This section discusses latency and a recommended process for defining and addressing latency issues in your network and application. Latency is the amount of time a packet takes to travel from source to destination. Together, latency and bandwidth define the speed and capacity of a network.
Latency Tuning Step 1: Determine the characteristics of your application Consider your application in terms of traffic pattern and amount of traffic generated.
Latency Tuning Step 4: Optimize the network and transport layers Depending on the results produced in steps 1, 2, and 3, optimize the network and transport layers. Optimizing the network and transport layers, may include, but is not limited to, these recommendations: Isolate any unnecessary TCP/IP traffic from the network. Choose smaller packets to reduce transit times through intermediate networking devices, as most of these devices are store-and-forward.
Latency Tuning Command options for optimizing network and transport layers A major contributor to latency for the network and transport layers is unnecessary retransmissions of data. The command-line interface has several command options to help you reduce these unnecessary retransmissions. These options are available through the command-line interface only, not the Web user interface. See the Digi Connect Family Command Reference for command descriptions.
Latency Tuning Considerations for using latency-related command options There are several considerations for using these latency-related command options: Changing the options from their defaults may violate RFCs. Decrementing the values for these options increases the amount of network activity, for example, there will be increased retransmissions. For a peer-to-peer application, you need to consider both sides of the connection and how options are set.
