disable certain services so the device runs only those services specifically needed. To improve device
security, you can disable non-secure services such as telnet.
Best practice Use the default network port numbers for basic network services because the port
numbers are used by most applications.
CAUTION! Exercise caution when enabling and disabling network services, particularly
disabling them. Changing certain settings can render a Digi Connect device inaccessible.
For example, disabling Advanced Digi Discovery Protocol (ADDP) prevents a network
from discovering the device, even if it is actually connected. Disabling HTTP and HTTPS
disables access to the web interface. Disabling basic services such as telnet, rlogin, and
so on makes the Command-Line interface inaccessible.
Supported basic network services and their default port numbers
For Digi devices with multiple serial ports, the network port number defaults for various services are
set based on the following formula:
base network port number + serial port number
The assumed default base is 2000. For example, the telnet passthrough service is set to network port
2001 for serial port 1, 2002 for serial port 2, and 2003 for serial port 3, and so on.
If you change a network port for a particular service, that is the only network port number that
changes. That change does not carry over to the other network ports. For example, if you change the
network port number for telnet passthrough from 2001 to 3001, that does not mean that the other
network ports changes to 3002, 3003, and so on.
There are two types of network services available:
n Basic services: You can access these services by connecting to a particular well-known
network port.
n Passthrough services: You can set up a specific type of service for a specific serial port. To use
the service, you must use the correct protocol and specify the correct network port. For
example, assuming default service ports and using a Linux host, here is how a user would
access the SSH and telnet passthrough services on port 1:
#> ssh -l fred digi16 -p 2501
#> telnet digi16 2101
The following table shows the network services, services provided, and the default network port
number for each service.

Device Discovery, also
known as Advanced Digi
Discovery Protocol (ADDP)
Discovery of Digi devices on a network. Disabling
this service disables use of the Digi Device
Discovery utility to locate the device. You cannot
change the network port number for ADDP from
its default.
