Linux is a freely-distributed UNIX-like operating system and is rapidly extending its applicability to PC-based measurement and control applications. Compared to other operating systems, Linux consumes less system resources and requires less hardware capabilities. ADLINK's DASK/X drivers are device drivers for custom data acquisition applications that run under Linux. DASK/X drivers provide common Application Programming Interfaces (APIs) for ADLINK's extensive family of PCI, CompactPCI, and PXI plug-in data acquisition cards, and utilize the full capabilities of these cards under the Linux environment. With DASK/X drivers, you can easily access all of the functionalities of ADLINK data acquisition cards to obtain optimal performance. ADLINK supports several of the major distributions with complete driver verification.
