TTL Trigger properties
#6
Hi Josh, 

This is spot on.  I didn't appreciate how different NI boards choose different TTL modes.  

Since I'm controlling NiDAQmx in C using the Python wrapper PyDAQmx making this switch in software turned out to be a bit of a trick.  In case anyone else is looking to do this what should be done is to pass the C channel property "SetDOOutputDriveType", the value: "DAQmx_Val_ActiveDrive", as described here.  Setting the TTL to open collector using "DAQmx_Val_OpenCollector" results in a TTL that does not trigger the PulsePal.
