Configuring the Digi Connect Devices
About TCP and UDP Port Numbers
Digi Connect devices use the following default TCP and UDP port numbering
conventions described in the following table:
You must ensure that the application or device that initiates communication with the Digi
Connect device uses these ports. If they cannot be configured to use these ports, you can
change the individual network port on the Digi Connect device, which allows you to use
different port numbers to designate a Telnet or raw connection to the serial port.
Serial Bridge Profile
The Serial Bridge profile allows users to create a serial bridge. A serial bridge is a network
connection between two serial devices, each of which uses a Digi Connect device. 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.
This profile configures each side of the bridge separately. Repeat the configuration for the
second Digi device server of the bridge specifying the IP address of the first Digi device
server.
For this connection type... Use this Port
Telnet to the serial port 2001 (TCP only)
Raw connection to the serial port 2101(TCP and UDP)
