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 server. The TCP Client allows the Digi device
server to automatically establish a TCP connection to an application or a network.
RFC 2217 Support
Digi Connect devices -except Digi Connect WAN support RFC 2217, an extension of the
Telnet protocol used to access serial devices over the network. RFC 2217 implementations
enable applications to set the parameters of remote serial ports (baud rate, flow control,
etc.), detect line signal changes, as well as receive and transmit data. The configuration
information provided in this section applies to Digi Connect devices functioning as RFC
2217 servers.
If using the RFC 2217 protocol, do not modify the port settings from the defaults. If you
have altered the device server, restore the factory default settings (see "Restore Device
Configuration to Factory Defaults" on page 127). No additional configuration is required.
UDP Sockets Profile
The UDP Sockets profile allows serial devices to communicate using UDP. (Not
supported in the Digi Connect WAN.) 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.
