Trouble with Multiple Instances of DAQ Assistant

Trouble with Multiple Instances of DAQ Assistant

Trouble with Multiple Instances of DAQ Assistant

(OP)
Hi,

I am trying to generate two waveforms simutaneously and output them to a NI DAQ box.  I used two signal simulators connected to two DAQ assistats.

The problem is only one of the two ever works.  Randomly when you start the VI, one or the other will output fine, but never two at the same time?

Any ideas?  Should I be using the DAQmx tools directly?

RE: Trouble with Multiple Instances of DAQ Assistant

What kind of inputs are you trying to read? Are they both analog or digital?
If both inputs are of the same type, you can inside one DAQ Assistant, configure it to read multiple channels. So you have to separate the signals using that Demux (don't remember it's name exactly [Unmerge Signals or something like this]) in the Signal Manipulation Pallete. The order is the same as set inside the DAQ Assistant: the top output signal is the one define in the top of the DAQ Assistant list. So you can treat each channel separately.
