The IS200VCMIH2BE operates as the VME‑bus master, broadcasting deterministic packets to all remote racks. Downstream VCMI boards extract assigned data from each broadcast frame.\u003c\/p\u003e\n\u003cp\u003eThe board contains \u003cstrong\u003eno programmable flash\u003c\/strong\u003e; firmware resides in the controller.
