SC-2345 and DAQCard-6062E

[ArrowHead]

Hello, I started working here at my new job, trying to fix what the previous guy messed up. My current setup is a SC-2345 board that plugs in to a DAQCard-6062E and that to the laptop. What i am trying to accomplish are 2 basic things. I have a transducer to measure pressure and several thermalcouples to measure tempeture. I have the transducer wired and powerd. The transducer produces a signal from 1 to 5 Volts depending on the pressure its at. I have the signal from the transducer connected to a SCC-FT01 module. When i open NI Measurement & Automotaion, under Devices & Interfaces >> NI-DAQmx Devices i have SC-2345 and a NI DAQCard-6062E: "Dev2" items. It seems everything nder SC-2345:"SCC1" is configured right. But when i select properties on NI DAQCard-6062E: "Dev2" I am not able to select SC-2345 (There is no option for it) currently its on TBX-68. Then if i do a self-test it fails. if i got to test panels and do a sample reading on  Dev2/ai0 it slowly goes upto 10 and then down to -10 and etc. Please help me how i can this setup to work properly. What is it that i need to check that so that i know everything is hooked up right? when i do a read from a DMM on the transducer i get a read of 1V which is right because 1V = 0 pressure. but Neither LabVIEW or NI can see this signal. Thank you for the help in advancce.

Hi ArrowHead,

Which slot on the 2345 is the FT01 hooked up to (J1-J8)?  Those different slots correspond to the different analog input channels on your 6062E.  The SCC configuration needs to know that it is using the 6062E, and it should also list which modules are connected to which slots.  You shouldn't need to set up the 2345 as an accessory of your DAQ card.  Make sure you are testing the channel that the FT01 is hooked up to, and that the mode is set to 'differential'.  In your case, you tested ai0, which corresponds to J1.

It is a little strange that the device is failing the self test.  Try resetting the device, then do the self test again.  Let us know what happens!

Thanks,
