The Abaco Systems VMIVME-5565-110000 is a Reflective Memory Node Card for VMEbus systems that enables deterministic, real-time data sharing across distributed processor networks using optical ring-based shared memory technology. Independent of bus structures and operating systems, this card delivers high-speed, software-transparent data transfer with minimal latency—ideal for simulations, industrial control, and advanced data acquisition where timing precision and data consistency are critical.
