Sir/Ma'm,
 
I have been trying to use Labview TPC/IP to received data from an Omega Iseries sensor.  I have been able to establish contact with the devise through a command prompt ping, through internet explorer, and a Labview Telnet example program.  I have not  been able to read data using a Labview Vis using Telnet or TCP/IP vis.  Any suggestions?  I am interested in using the TCP/IP protocol or Telnet to receive the data in a labview datalogging application.

Which specific device are you trying to talk to? In general, you need to know the protocol, as in what commands to send out, and how many bytes to read, and whether the device is continuously sending out these packets, or if it does so only in response to a command.

I have checked Omega and newport websites and the NI website, which do not have labview drivers for the Omega iSeries.  I have been successful establishing the port connections with a labview telnet program, but I have not been successful in finding the correct syntax or command in the omega user guide to read the data.

What is the model number of the device that you're using? Can't help without knowing what you're talking to...

I am talking to a Omega iServer CNiTH-i8DH42-2-C4EI.  It is a humidity sensor/controller.  When I use the Labview TELNET program, I can only seem to get configuration and setup menus.  When I use the ? command.  I don't seem to have any sensor reading commands available.
