DESCRIPTION: |
|
The HAWKE VME NTDS interface Board from Sabtech is an off-the shelf, NDI solution that provides a high speed intelligent 32-bit interface between the VMEbus and MIL-STD 1397 A/B input/output devices. This capability allows direct connection of military computer equipment to the open architecture VMEbus for application such as software development, simulation and training support. |
