Introduction Hardware features A summary of hardware features, including power-supply information, is in "Hardware specifications" on page 169. For detailed hardware specifications, see the Hardware Reference and data sheet for your Digi Connect product. Network interface features A detailed list of network interface features is in Chapter 7, "Specifications and certifications". See also the data sheet for your Digi product.
Introduction IP protocol support All Digi devices include a Robust on-board TCP/IP stack with a built-in web server.
Introduction 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.
Introduction 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.
Introduction 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.
Introduction 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.
Introduction 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.
Introduction Configuration management Once a Digi device is configured and running, configuration-management tasks need to be periodically performed, such as: Upgrading firmware Copying configurations to and from a remote host Software and factory resets Rebooting the device Memory management File management For more information on these configuration-management tasks, see Chapter 5, "Digi device administration".
Introduction 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.
Introduction 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.
Introduction 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.
Introduction 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. Configuration capabilities Device configuration involves setting values and enabling features for such areas as: Network configuration: Specifying the device’s IP address settings, network-service settings, and advanced network settings.
Introduction The Digi Device Setup wizard The Digi Device Setup Wizard is a wizard for quick initial configuration of Digi devices. It is available from the Digi Support site and also provided on the Software and Documentation CD shipped with each product. It assigns an IP address for the device, configures the device’s serial port parameters based on a selected configuration scenario called a port profile, and determines whether RealPort software needs to be installed.
Introduction 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.
Introduction iDigi™ Platform interface The iDigi Platform provides remote network management of all connected hardware. In contrast to the one-user-to-one device model of other Digi device interfaces, the iDigi Platform uses a oneuser-to-many-devices interface model. By providing a central point of access to remote devices or groups of devices, the iDigi Platform makes it easier for you to manage many devices.
Introduction 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, GPIO (for all products except Digi Connect SP, Digi Connect Wi-SP), Alarms, System, Remote Management, UsersSecurity. Most of the configurable features are arranged by most basic settings on a page, with associated and advanced settings accessible from that page.
Introduction 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.
Introduction The Java applet interface is a completely customizable interface. For example, the web interface can be changed by replacing the Digi logo with your company logo or changing the colors used in the interface workspace. 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.
Introduction 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.
Introduction 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. SNMP is easy to implement in extensive networks.
Introduction 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.
Introduction 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. As with configuration and monitoring, administration can be done from a number of interfaces, including the web interface, command line, and the iDigi Platform.

Configure Digi devices Configure Digi devices C H A P T E R 3 This chapter describes how to configure a Digi device. It covers these topics: "Default IP address and methods for assigning an IP address" on page 46 "Configuration through the iDigi Platform" on page 50 "Configuration through the Digi Device Setup Wizard" on page 56.
Configure Digi devices Default IP address and methods for assigning an IP address 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.
Configure Digi devices 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.
Configure Digi devices Configure an IP address using DHCP An IP address can also be configured using Dynamic Host Configuration Protocol (DHCP). DHCP is an Internet protocol for automating the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses and deliver TCP/IP stack configuration parameters. As mentioned previously, all products that have a cellular (WAN) interface ship with static IP address for the Ethernet port of 192.168.1.
Configure Digi devices Configure an IP address from the command-line interface The set network command configures an IP address from the command line. Include the following parameters: ip=device ip: The IP address for the device. gateway=gateway: The network gateway IP address. submask=device submask: The device subnet mask. dhcp=off: Turns off use of the Dynamic Host Configuration Protocol (DHCP), so that the IP address assigned is permanent.

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. Enter the user name and password for the device.
Configure Digi devices Network configuration settings The Network configuration pages include: Ethernet IP settings: For viewing IP address settings and changing as needed. See page 66. WiFi IP settings: For setting the IP address used for wireless LAN communication. See page 70. WiFi LAN settings: For setting basic options for wireless LAN devices such as network name and network connection options. See page 70.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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. The uplink interface provides a single Internet Protocol (IP) address for all communication to and from the devices at a single location.
Configure Digi devices 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. 1 Connect a laptop to one of the Ethernet Switch ports on the Digi Connect ES 4/ 8 SB with Switch and open the web interface.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices The table shows network services, services provided, and the default network port number for each service. 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices – 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.
Configure Digi devices – 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.
Configure Digi devices 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.
Configure Digi devices 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 These settings are used to fine-tune IP address settings. 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.
Configure Digi devices 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.
Configure Digi devices Serial port settings Use the Serial Port Configuration page 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices Local Configuration profile The Local Configuration profile allows for connecting standard terminals or terminal emulation programs to the serial port in order to use the serial port as a console to access the command line interface. Profile settings enable and disable access to the command line.
Configure Digi devices Custom Profile The Custom port profile displays all serial-port settings, which can be changed as needed. Use the Custom profile only if the use of the serial port does not fit into any of the predefined port profiles, for example, if network connections involve a mix of TCP and UDP sockets. Basic serial settings After selecting a port profile, the profile settings are displayed. Choose the appropriate features for your environment.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices 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.
Configure Digi devices Additional implementation required for input and output choices Changing the GPIO pin settings from Serial to Input or Output means you are responsible for implementing how the pins and signals will work, including developing any applications, signalhandling, and hardware.
Configure Digi devices 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. These events include changes in GPIO signals, certain data patterns being detected in the data stream Alarm notification settings On the Alarms page, the Alarm Notification Settings control the following: Enable alarm notifications: Enables or disables all alarm processing for the Digi Connect device.
Configure Digi devices 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. Enable: Checkbox indicates whether the alarm is currently enabled or disabled.
Configure Digi devices 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.

Changing public and private community names from their defaults is recommended to prevent unauthorized access to the device. Public community: The password required to get SNMP-managed objects. The default is public.
Configure Digi devices Remote management settings The Remote Management configuration page sets up the connection to the iDigi Platform remote management server so the Digi device knows how to connect to the server. The iDigi Platform allows devices to be configured and managed from remote locations. To use the iDigi Platform as a remote manager of a Digi device, follow the procedures that begin on page 50. There are two pages of remote management settings: Connections and Advanced settings.
Configure Digi devices A server-initiated connection works the opposite way. The remote management server opens a TCP connection, and the Digi device must be listening for the connection to the remote management server to occur. An advantage of server-initiated connections is that you are not charged for sending the keep-alive bytes that are used in client-initiated connections.
Configure Digi devices Advanced remote management settings The default settings for remote management usually work for most situations. These Advanced settings are used in advanced situations. They are used to configure the idle timeout for the connection between the Digi device and the remote management server, 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.
Configure Digi devices – HTTP over Proxy Settings: The settings required to communicate over a proxy network using HTTP. These settings apply when Automatic or HTTP over Proxy connection methods are selected. Hostname: The name of the proxy host. TCP Port: The network port number for the TCP network service on the proxy host. Username: Password: The username and password for logging on to the proxy host.
Configure Digi devices Manually configure a Digi device to connect to the iDigi Platform To use iDigi Platform as a device manager for your Digi device, you need to manually configure the Digi device to connect to iDigi Platform. 1 Open the web interface for the Digi device and go to Configuration > Remote Management. 2 On the Remote Management settings page, enter the URL of the iDigi Platform connectivity server (for example, sd1-na.idigi.
Configure Digi devices User settings User 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. User authentication settings are on the Users settings page. User access settings: the device interfaces that a user can access, such as the command line or web interface.

Digi device administration Virtual Private Network (VPN) Identities The Virtual Private Networking (VPN) Identities database is used to load host certificates and keys. Identity certificates and keys allow for IPSec authentication and secure key exchange with ISAKMP/IKE using RSA or DSA signatures. The VPN identity certificate must be issued by a CA trusted by the peer. Upload VPN Identity Keys and Certificates: Use this section to upload VPN RSA or DSA identity keys and certificates.
Digi device administration Secure Sockets Layer (SSL) / Transport Layer Security (TLS) Certificates The Secure Sockets Layer (SSL) and Transport Layer Security (TLS) databases are used to load host certificates and keys, as well as peer certificates and revocations. Identity Certificates and Keys – Upload SSL/TLS Identity Keys and Certificates: use this section to upload SSL/TLS RSA or DSA identity keys and certificates. Identity certificate and key files may be in ASN.
Digi device administration 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.
Digi device administration Restore a device configuration to factory defaults Restoring a Digi device to its factory default settings clears all current configuration settings except the IP address settings and host key settings. In addition, any files that were loaded into the device through the File Management page such as custom-interface files and applet files are retained. See "File management" on page 151 for information on loading and deleting files.
Digi device administration 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. 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. For Digi Connect EM or Digi Connect Wi-EM, the Reset button is located between P3 and CR1, as shown: Reset button Digi Connect ME and Digi Connect Wi-ME do not have a reset button.
Digi device administration 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. Note that shorting pin 14 simply reboots the unit but does not restore the configuration. 4 After a few seconds you may see a 1-1-1 blink once on some devices. 5 Wait until you see the Status LED blink a 1-5-1 pattern, then release the reset button. 6 Wait for the device to boot up.

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. Note that these options are available through the command-line interface only, and not the Web user interface. For complete descriptions of these commands and options, see the Digi Connect Family Command Reference.
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.

Address Resolution Protocol (ARP) A protocol for mapping an Internet Protocol address () to a physical machine address that is recognized in the local network.
configuration applet See Java applet interface. configuration management Managing the files and settings that contain device configuration information. Configuration management tasks include copying device configuration files to and from a remote host, upgrading device firmware, and resetting the device configuration to factory defaults. CTS Clear to Send. device server A one- or two-port intelligent network device that converts serial data into network data.
File Transfer Protocol (FTP) A standard Internet protocol that specifies the simplest way to exchange files between computers on the Internet. HyperText Transfer Protocol (HTTP) An application protocol in the TCP/IP suite that defines the rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide web (WWW).
NAT NAT (Network Address Translation) is the translation of an Internet Protocol address () used in one network to a different IP address known in another network through a NAT table that does the global-to-local and local-to-global IP address mapping. This increases security since each outgoing or incoming request must go through a translation process that also authenticates the request or matches it to a previous request.
Remote Command Interface (RCI) A programmatic interface for configuring and controlling Connect family devices. RCI is an XML-based request/response protocol that allows a caller to query and modify device configurations, access statistics, reboot the device, and reset the device to factory defaults. Unlike other configuration interfaces that are designed for a user, such as the command-line or browser interfaces, RCI is designed to be used by a program.
Simple Mail Transfer Protocol (SMTP) A TCP/IP protocol used in sending and receiving e-mail. Since it is limited in its ability to queue messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP, that let the user save messages in a server mailbox and download them periodically from the server. SMTP usually is implemented to operate over Internet port 25. An alternative to SMTP that is widely used in Europe is X.400.
Trivial File Transfer Protocol (TFTP) An Internet software utility for transferring files that is simpler to use than the File Transfer Protocol (FTP) but less capable. It is used where user authentication and directory visibility are not required. TFTP uses the User Datagram Protocol (UDP) rather than the Transmission Control Protocol (TCP). TFTP is described formally in Request for Comments (RFC) 1350.
