I'm a student and new to Labview and DAQ cards, so this should be easy for most of you reading this...
I have an IOTECH 1000 series DAQ card. I am able to input a sine wave into one channel and get results of the A/D conversion; however, I cannot get more than one channel to work...
I have configured the channels I want and am getting data, but it isn't valid data. I have also configured for single-ended and am getting errors (invalid configuration error #5601).
Specifically, when I am configured for one input 0(1) and differential, I get what seems to be valid data (sine wave from signal generator on CH0 and SGND). When I configure for two channels 0(1),1(1) I get crap...moreoever, the second column of the array is nothing but ones and zeros, which led me to believe the DAQ is set for differential by default. So, I configured it for single-ended and I get the same data, but I also get an error for the single-ended configuration (invalid configuration error# 5601). Also, when I tie the same input to CH0 and CH1, I get ones and zeros in both columns of the array.
The documentation for IOTECH seems to be ok for initial setup, but they don't give any examples. They say that it's compatible with Labview and provide a pdf file for using the DAQ with Labview, but it's nothing more than basic setup/config info for the VI's. I've searched and searched and can't find a clear answer or any information that seems to help. I also ran across a comment about a HI and LO side for the analog inputs...but they say it has 16 single-ended inputs...and I have 16 analog inputs on my card...nothing about a HI and LO. Anyway...
I hope this was clear. If not, feel free to ask for clarification and additional information. I'm sure anyone who has used this DAQ card and Labview can answer this question. Any help/advice is greatly appreciated.
