TCP and UDP network port numbering conventions
Digi devices use these conventions for TCP and UDP network port numbering.
For this connection type...
Telnet to the serial port
Raw connection to the serial port
Ensure that the application or Digi device that initiates communication with the uses these network
ports numbers. If they cannot be configured to use these network port numbers, change the
network port on the Digi device.
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.
Serial Bridge profile
The Serial Bridge profile configures one side of a serial bridge. A serial bridge connects two serial
devices over the network, each of which uses a Digi device, as if they were connected with a serial
cable. The serial devices "think" they are communicating with each other across a serial cable
using serial communication techniques. There is no need to reconfigure the server or the serial
device. Neither is aware of the intervening network. Serial bridging is also known as
serial tunneling.
This profile configures each side of the bridge separately. Repeat the configuration for the second
Digi device of the bridge, specifying the IP address of the first Digi device.
