Hi,
I think you have to write a register level driver for the PCI-6034E to use RTX... No National Instruments driver exists for E series and RTX.
Below is a link to help you ....
Personnally, I recommend you to use new M series (similar to E series) because they are supported under RTX via NI-DAQmx Base 2.0.
