PXI-7813R Digital lines pull-down?

[gyc]

Hi all.

Does anyone know if the digital lines of PXI-7813R have a pull-down or pull-up resistor in their internal cicuitry?

From the manual, I would conclude that there is no pull-up, since one needs to add it when DIO lines are programmed for output AND are driving 5V logic, but nothing is explicitely stated about pull-downs.

Thanks in advance to all that may help.
