GE IS215VCMIH2C VME Communications Interface Board

Overview

The GE IS215VCMIH2C is a VME Communications Interface Board for Mark VI turbines. It manages high-speed communication between the main processor, I/O boards, and the IONet network. It ensures real-time data exchange and supports Triple Modular Redundancy (TMR) for fault-tolerant operation. The board secures communication with AES-128 encryption and a built-in firewall, and it interfaces directly with all I/O modules.
