We want to receive data from a Multi-para patient monitor

Question

Want to get / receive data from a patient monitor with multiple pairs.

I googled a lot, but could not find the right solution. These monitors are mainly manufactured by the Chinese, and no documents regarding the same are provided.

In the monitors, a network cable port is available, as well as one third-party software called Central Station that displays information on a computer (we want to do the same, but independently for data analysis). But we have no way to contact this software manufacturer or we cannot find out how they receive this data.

So, anyone can help how we can do this or how I can find a solution to the same thing.

Thanks.

Edit:

With WIRESHARK we can sniff network data, and it looks like this:

From this, at least I can know that it collects information from these two ip ie 192.168.2.34 and 192.168.2.35, and its port is 52435 and 47327.

Can anyone tell how can I do the same with programming in java ??
