For those applications where VMEbus slots are at a premium, the VME Swift-PAKs™ are the perfect solution to increase performance while reducing slot space.

Utilizing our state-of-the-art Swift™ PMC technology in a VMEbus environment, the VME Swift-PAK™ allows users the flexibility to pack up to two (2) complete NTDS I/O channels in a single VMEbus slot. These channels can be any combination of NTDS Parallel or Serial I/O channels. The VME Swift-Pak™ includes a powerful set of standard features and support for most popular operating systems, making it ideally suited for normal NTDS I/O functions as well as passive tap applications.
