This product is a PCI Express bus-compliant interface card that supports transfer by bus mastering and performs input/output between the external device and digital signal. This product features unisolated LVTTL level (Operating voltage : 3.3V) I/O 32channels and you can select input / output in 16 units. Bus master transfer makes it possible to sample quickly large data with transfer rate at 20MHz maximum. It can be used as a pattern generator that outputs arbitrary digital patterns at high speed. It can also be used as a general-purpose I/O card when bus mastering is not used. Windows/Linux driver is bundled with this product. Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.
