DAQmx multiple channels from multiple devices

[nano_era]

Hello,

General question here. If I am using two devices which are exactly the same, can I and should I use one DAQmx task to read all/only analog inputs? Or is it better to use a task for each device?

Thanks

Hi there,

You actually can't use a single task to read from multiple devices.  You'll get error -200558.  You will need to create a separate task for each device.

Hope that helps!

To supplement DianeS's answer, I'd like to point out that this is actually possible for some devices, provided all channels share common timing.  Have a look at this Knowledge Base to see which devices support this.

I have done this with cDaq (shared timing enine), what devices are you using.
