Why Does My Specified Channel Not Work as an Analog Trigger Source in DAQmx? Primary Software: Driver Software>>NI-DAQmxPrimary Software Version: 7.0 Primary Software Fixed Version: N/A Secondary Software: N/A Hardware: Multifunction DAQ (MIO)>>M Series
Problem: I have configured my analog trigger to trigger off of one of my device's analog input channels, but I receive DAQmx error -200265. Solution: The trigger source input to the DAQmx Start Trigger (Analog Edge) must be either a channel name that you've specified in DAQmx Create Channel (AI-Voltage-Basic).vi or an appropriate APFI line. Specifying the device and channel name will not work. For example, if you want to trigger off of an analog input channel, and you wire the name to assign terminal of the DAQmx Create Channel (AI-Voltage-Basic).vi with the value “Voltage” then you must also wire “Voltage” to the source terminal on the DAQmx Start Trigger (Analog Edge).vi. Wiring the physical channel name (i.e. “dev1/ai0”, “M-Series1/ai1”, etc.) will result in a DAQmx error -200265. The attached image below highlights the relevant terminals in an example VI.
