Protocols, ports and connections
The Ethernet protocols supported by your device allow simultaneous
connections through the IP service ports.
NOTE: Some protocol port numbers are read-only and not
configurable.

By enabling or disabling TCP/IP protocols, you can control whether or not your meter accepts new socket connection requests. Changing settings for one port does not impact the other existing connections. Depending on the protocol, you can also change the port number.
