Proven high-performance serial NTDS for VMEbus computers

Versatile single board computer with serial NTDS I/O channel

The Serial NTDS connects VMEbus computers to military computers and peripherals with MIL-STD-1397C Type D (NTDS Serial) and E (Low Level Serial) interfaces. But it’s capabilities go far beyond those of a conventional I/O board. It’s architecture is unique in the industry because it combines the power and reliability of a 32-bit MC68020 processor and an industry standard VMEbus interface controller. With onboard memory, an onboard debugger, and the ability to run C or assembly language programs from RAM or EPROM, the Serial NTDS is a powerful and versatile single board computer with a full duplex NTDS I/O channel. The Serial NTDS supports distributed processing with the ability to run user applications onboard, which improves VMEbus bandwidth and offloads the host computer.
