Appendix C – Port Assignment on the
unit
Port Allocation
It is possible to identify specic ports that will be used for functionality supported on the unit.
These functions are:
FTP
Telnet
HTTP
Telemetry Control
Audio
Debug
Some of these ports have default settings that will link to the default settings of a standard network
infrastructure, e.g. port 21 default port for FTP, port 80 default port for HTTP.
However if these default port numbers have already been allocated to other devices on the network
then it is possible to identify alternative port numbers.
NOTE: It’s important to ensure all devices that are part of the system conguration are all allocated
the same port number otherwise communication between the devices will not be successful.
To view the ports that have been enabled and congured on the unit, select Network -> Firewall
Options. This details the port numbers, type of connection, application and use.
The screen shot shows the default settings for each of the features that utilises a port number as
part of its communication path.
Telnet <IP address or unit> 5201
It is possible to redene the port allocation for FTP, telnet and HTTP, how this is achieved is detailed
in the Conguration section of this manual.
The telemetry control, audio port and engineering debug are default settings and are not
congurable; these port numbers must be given to the Network Manager to ensure there are no
other devices on the network using these ports.
Using a telnet session it is possible to telnet to a specic port to obtain debug information, for
example at the prompt enter:
