Thread Subject: addchannel in daq problem

Hello

I have problem with adding channels to analog input. I can add
channel with number less than 8.
addchannel(ai, [0:7]); %allright

when I add channel with higher number, I get error ...
addchannel(ai, [8]);
??? Error using ==> daqdevice.addchannel
The channel(s) being added are invalid for the current input type.

I would like to use more than 8 analog input channels of my measure
card NI6024 with 16 analog input channels.

thanks witt

Hello,
is it possible that your card have 8 differential channels / 16 single-ended
channels?
Perhaps you have to change your input-Type to single-ended with
ai.InputType = 'SingleEnded';
Does that help you?

Best regards
Andrea
