For the last few months I have be struggling with getting a PT-104 working with Labview 8.5. I have had some success but I have never been able to get data consistently. I have read through the discussion forums on this web site and the National Instruments web site and found a few other people who have encountered similar problems.
Anyway, I have written my own software but would like to clear up a couple of points:
The Labview vi has an option for 2,3&4 wire PRT's, how do I write the code to ensure that I am making a four wire measurement?
Is the protocol in the manual the full protocol for the unit?
Also it would be helpful if you add a little more detail to the calibration data, ie state the the calibration are bytes 19-22 for channel and and that 19 is the LSB.
