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. Autoconnection is enabled through
the TCP Sockets profile’s setting labeled Automatically establish TCP connections.
RFC 2217 support
Digi devices 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 device functioning as RFC 2217 servers.
If using the RFC 2217 protocol, do not modify the port settings from the defaults. If the
port settings have been changed, restore the factory default settings (see "Restore a device
configuration to factory defaults" on page 215). No additional configuration is required.
