Description
Product Overview
The IS215VCMIH2B VME Bus Master Controller Board from GE’s Mark VI System serves as the central communication interface between controllers, I/O boards, and the IONet system network. It manages rack-wide board IDs and supports both simplex and triple modular redundant (TMR) configurations.
This board monitors internal power buses and diagnostic signals via the J301 backplane connector. It supports analog and digital feedback, ground fault detection, and external monitoring circuits. The board includes three IONet ports for scalable system integration.

Features & Performance
The IS215VCMIH2B board functions as the VME bus master and coordinates communication across control and I/O racks. It supports multiple I/O racks per IONet and ensures synchronized data exchange across redundant channels (R, S, T).
The board continuously monitors voltage levels and triggers alarms based on configurable thresholds. It integrates seamlessly with power distribution modules and supports both local and remote I/O configurations.
