Network Address Translation (NAT)/Port Forwarding (only some products have NAT)
The following sections provide an overview of some of the services provided by these protocols.
Serial data communication over TCP and UDP
Digi devices support serial data communication over TCP and UDP. The 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 are based on data and or serial hardware signals.
Control forwarding characteristics based on size, time, and pattern.

Allow incoming raw, telnet, and SSL/TLS (secure-socket) connections.

Support RFC 2217, an extension of the telnet protocol.

•
Serial data communication over UDP, also known as udpserial, can automatically perform the following
functions:
Digi Connect products can automatically send serial data to one or more devices or systems on the network

using UDP sockets. Options for sending data include whether specific data is on the serial line, a specific time
period has elapsed, or after the specified number of bytes has been received on the serial port.
Control forwarding characteristics based on size, time, and patterns.

Support incoming datagrams from multiple destinations.

Support outgoing datagrams sent to multiple destinations.

•
TCP/UDP forwarding characteristics.
•
Extended communication control on TCP/UDP data paths.
Timeout

Hangup

User-configurable Socket ID string (text string identifier on autoconnect only)

Dynamic Host Configuration Protocol (DHCP)
You can use Dynamic Host Configuration Protocol (DHCP) to automatically assign IP addresses, deliver TCP/IP stack
configuration parameters such as the subnet mask and default router, and provide other configuration information.
For more details, see
Auto-IP
The Auto-IP protocol automatically assigns an IP address from a reserved pool of standard Auto-IP addresses to the
computer on which it is installed. Digi devices automatically obtain their IP addresses from a DHCP server. If the
DHCP server is unavailable or nonexistent, Auto-IP assigns the device an IP address. For more details, see
an IP address using Auto-IP
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) manages and monitors network devices. The SNMP architecture
enables a network administrator to manage:
•
Nodes—servers, workstations, routers, switches, hubs, etc.—on an IP network
