TCP Port Question

[JeffOverton]

Hey gang,

  I'm pretty new to TCP connections, so I figure it's better to ask about this stuff up front than to ruin my company's network.  Eventually, I'm going to have a networked laptop that will also be connected to a deployed FieldPoint, and I'm going to be using TCP for server/client conversations between the FP and PC.  The question is, are there any ports that are going to cause problems?  Is there a range that is preferred for hardware communications?

Hi Jeff.  With just your PC talking to Fieldpoint, there shouldn't be any ports you can select that will
cause problems with the network.

As far as choosing ports to use, I would recommend ports > 1024 as a minimum, and better would
be > 49152.  You really just want to avoid picking a port (on the PC side) that some other service
uses.  The Fieldpoint side should be happy using (almost) anything, but again > 49152 is safest.

Thanks, Matt.  That's exactly the answer I was looking for.

Hi guys,

I have a question: I need to create a PDA version of my software and here is the situation:

It is a server client application which works over DSTP protocol for communication. But the labVIEW PDA module does not support DSTP protocol so: I must create a PDA client which reads data using TCP protocol.

So to simplify, the scope here is: To create a TCP client who reads data from DSTP server!!

Thanks,
