FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PCI-7811R provide analog I/O?

No. NI identifies the 781xR family as reconfigurable digital I/O without analog input or output channels.

How does the PCI-7811R differ from the PCI-7813R?

Both have 160 digital lines. The PCI-7811R uses a Virtex-II V1000 FPGA, while the PCI-7813R uses a larger Virtex-II V3000 FPGA.

Which connection accessories does NI list for this model?

NI's accessory guide lists SHC68-68-RDIO cabling and SCB-68 or SCB-68A connector blocks for PCI-7811. Consult the guide and connector-specific pinout before wiring.
