PCI-6024E Daq I/O Board

[matethreat]

I have purchased a PCI-6024E I/O Board and a CB-68LPR I/O Connector block. I have wired into the Analog Input Channel 0. All i am trying to do is have labview aquire the voltage I have inputed into this channel. The voltage range of the input is from 2 to 5 volts. I am using the (Aquire 1 point from 1 channel.vi) and the vi returns the upper limit of my range (5 Volts). When using a multi meter I read 2.3 volts. I have exhausted all avenues I know of for getting this to read the proper voltage. According to the manual it should be a simple procedure to read the voltage from one channel, but I am having no luck.

Any help would be greatly appreciated.

Thanks,

Aaron

If your connections are between channel 0 and AIGND, make sure your board is configured for single ended input. If you are connected to channel 0 and channel 8, make sure your are configured for differential inputs. If you are connected differentially, measure the potential between your signal an AIGND, it must be less than 15V (common mode voltage).

Aaron, one thing you have to consider is whether you are grounding the connection. If you connect to the AIGND, you need to switch your ComponentWorks Control property to Single-Ended Input. Furthermore, make sure you are specifying the correct channel. What you can also do is check the samples provided and compare your code versus the code in the examples. Another problem may be that you haven't started the scanning series or have done simply a one shot scan instead of a continuous read. I believe the directory is:
MeasurementStudio>LabView>Samples>DAQ>Analog Input. Hope this helps.
