Introduction

The IMASI03 is a single printed circuit board that occupies one slot in an INFI 90 Module Mounting Unit (MMU). Two captive latches on the module faceplate secure it to the MMU. The slave module has three card edge connectors for external signals and power: P1, P2, and P3. P1 connects to the supply voltages. P2 connects the IMASI03 to the slave expander bus, over which it communicates with the MFP.
