Hello folks!
I have two NI SCXI-1305 modules installed in an NI SCXI-1000 chassis. Each SCXI-1305 has 8 analog input channels.
I have no problem accessing all the channels of the first module. But I just cannot get access to any channels of the 2nd module.
ai = analoginput('nidaq','Dev1');
ch=addchannel(ai,0:7);
=========Works fine, but
ch=addchannel(ai,0:8); <<<=== trying to add an extra channel to the ai object
=========Does not work. error msg:
?? Error using ==> daqdevice.addchannel at 198
The channels(s) being added are invalid for the current input type.
I believe both modules are installed properly as they both passed the "self test" in NI-MAX successfully.
Do I miss anything? A colleague of mine using LabView..,. he has no problem ccessing both modules
I use Matlab 7.11.0.584 (R2010b), with Data Acquisition Toolbox Version 2.17 (R2010b)
Thank you!
