Use NI USB-6259 Mass Term to output analog signals through 3 channels

[过客wasd]

Hello everyone

I‘m want to use NI USB-6259 Mass Term to generate analog voltage signals in 3 channels: ao0,ao1 and ao2.

But there is a problem.

I set 3 different wave forms for the 3 channels, and run the labview program.

No error is shown but only 2 channels: ao0 and ao1 is generating signals, ao2 is not work at all.

I want to know why it is not working. 6259 has 4 analog out put channels and I set the DAQmx VIs correctly. ( if not, i wont get analog output through 2 channels )

Plz help me, im very grateful

Hi wasd,

I‘m want to use NI USB-6259 Mass Term to generate analog voltage signals in 3 channels: ao0,ao1 and ao2.

Please check the routing of the 3rd output channel: is it at the connector you expect it?

Did you check the ao2 signal when not using the "mass term" unit? (Please use full words instead of abbrevations!)

Plz help me

To get more help you should supply more information like current wiring, correct unit numbers and descriptions!

And again: please use full words!

In addition to what GerdW suggests, if you are having a problem with your LabVIEW code, then you should attach your VI(s) (no pictures, please) so we can see what you are doing and (possibly) suggest how to fix it.
