NI-SCOPE provides application programming interfaces for many development environments.
Environment NI PXI-5124 Note To ensure that the NI PXI-5124 cools effectively, follow the guidelines in the Maintain Forced Air Cooling Note to Users included in the NI PXI-5124 kit. The NI PXI-5124 is intended for indoor use only.
NI PCI-5124 To ensure that the NI PCI-5124 cools effectively, make sure that the chassis in which it is used has active cooling that provides at least some airflow across the PCI card cage. To maximize airflow and extend the life of the device, leave any adjacent PCI slots empty. Refer to the Maintain Forced Air Cooling Note to Users included in the NI PCI-5124 kit for important cooling information. The NI PCI-5124 is intended for indoor use only.
