Hello -
I am using NIDAQmx with a c-code to control the output of a cDAQ 9260 card while simultaneously reading some inputs using the 9239 card. When setting up the "write" channel, I have enabled SetAO_IdleOutputBehavior so that the card continues to output the last value. This works, i.e., if I test the output with a multimeter, the output is maintained even after clearing the write task.
However, if I do a simultaneous read/write where the read is triggered to start when the write starts using /ao/starttrigger, the output of the card right before the trigger drops to zero. Once the read is done, the output continues to maintain the last value. However, if the read/write loop is repeated, again, just before the output starts, the voltage output drops to zero.
Is there anyway to maintain the output before a triggered event?
Thanks -
