Ports and protocols required via Ethernet connection

Could someone advise what ports and protocols IQAN software are using when connecting via Ethernet to MD4?

When starting Ethernet communication the IQAN software begins with discovering modules on the same network. For this UDP port 8324 is used. The result is shown in the Ethernet connection dialog.

When selecting one of the discovered master modules UDP port 8325 is used to communicate with the module.

If you want to communicate with a master module that is not connected to the same router as your computer it will not show up as a discovered module. In this case you have to know the IP address of the master module and use the "Static modules" tab of the Ethernet connection dialog instead. When connecting to a master module using this way we use TCP on port 8323 instead. This makes it easier and more reliable to e.g. connect over a VPN connection. Note that this connection is considered to be a remote connection and will by default trigger a confirmation message on the MD4 before connecting.

Would it be possible to get access to the communication protocol IQAN use?


Unfortunately no, we do not provide the internal IQAN protocols to external parties.
