How can I communicate PXI-6509 by Static DIO Register-Level Programming?

[PXI-6509]

- How can I communicate PXI-6509 by Static DIO Register-Level Programming?

  PXI-6509 physically Port0 is connected to Port1.

  For checking all connections are correct for this case so I have used DAQmx Test Panel. Just in case everything is ok.

  In this case I interested in to communicate the PXI6509 by Register-Level Programming.  

  I have tried to use Open VISA Test Panel for sending and reading data (in MAX explorer) and

  use NI-Spy for checking communication data.

  The first step I configured Port0 to Outputs state and Port1 to Inputs state.

  The second step I setup Port0 to 0xAA.

  The third step I read back Port1 and expected data will be 0xAA but just only 0x0. Why???

Hello!

We don't do support on register-level programming but the problem you are experiencing might be due to tri-state on the ports?

Please check this manual that covers register programming of the device you are using:
