TCP/IP fails but HTTP works. Why?

[therealkilkenny]

Hi all,

Bit of a newbie when it comes to TCP/IP and HTTP. I am trying to talk to a SoMat eDAQ lite and stream data off it by making the appropriate call as shown in the pictures that are attached.

This seems to work fine if I use the HTTP subVI and saves a file to disk. I want to get access to the data so want to use the TCP/IP to get the data in chunks but it throws error 56 on the read TCP/IP subVI call.

Any advice?
