Hello,
For a spectroscopy project, I've tweaked the example Multi-Function-Synch-AO-AI.vi to continually write values out a single DAC channel and simultaneously read in two ADC channels. Works fine.
Now, I'd like to add the ability to read a few more ADC channels (house-keeping data) at a much lower frequency. Again, I started with an example (Acq&Graph Voltage-Inc) to read three consecutive channels just one read each channel. Also works fine.
When I add my Housekeeping vi to my Spectroscopy vi, I get an error saying
-----
Error -50103 occurred at DAQmx Start Task.vi:22
Possible reason(s):
NI Platform Services: The specified resource is reserved. The operation could not be completed as specified.
Task Name: _unnamedTask<5CE>

I not new to LabVIEW, but am new to DAQ hardware. Thanks in advance for any help!
Using NI USB-6211 running on WinXP with LabVIEW 2011.

Ah, that would explain it.
thanks much!

Hello,
I am using Labview to collect data from two channels: Dev1/ai0 and Dev1/ai1. I want to collect the data at different frequencies for each channel. It seems that you have done something similar, if I understand your question correctly. Would you be willing to post your vi as a reference if you were able to collect data at different frequencies for different channels on the same DAQmx read task?
Thanks very much,
