Although NPort devices do not have a function to monitor the data passing through them, there is another way to monitor the data.

Note: This method can only monitor the data transferred from the serial side to the Ethernet side.

1. If you are using the Real COM mode:

    A. In the settings, change Max connection to a value greater than 1 (default value is 1).

    B. Map the COM ports with the driver and get the TCP port. The TCP port is 950 in the following example.

    C. Connect to the NPort by using a TCP Client and use the TCP port as the Dest. port.   

         You will be able to see the data passing from the serial side to the Ethernet side.

2. If you are using the TCP Server mode:

    A. In the settings, change Max connection to a value greater than 1 (default value is 1).

    B. Get the TCP port number (The TCP port value in the following example is 4001).

    C. Connect to the NPort using a TCP Client and the TCP port number.

         You will be able to see the data passing from the serial side to the Ethernet side
