i4000 - Quad M-module carrier for VMEbus
User Manual	Version: 1.2

2.PRODUCT OVERVIEW

2.1.INTRODUCTION

The i4000 provides a compact high-performance VMEbus gateway to the M-module interface. The i4000 has a 6U form factor. Four M-modules can be mounted on the i4000.

The M-module interface of the i4000 complies with the M-module Specification. The M-module specification is ANSI approved. The M-module interface features A8, A24, D16 and D32 access types.

2.2.TECHNICAL OVERVIEW

Below an overview of the i4000 is listed.

VME interface

•A24/A16, D16/D08(EO)

•D08(O) (DYN) interrupt vector (vector unique per module)

•I(x) interrupt level (on the i4000/NP2 this is programmable per module)

M-module interface

•4 M-module Interfaces (A08/A24, D16/D32)

•INTA software-end-of interrupt

•INTB hardware-end-of-interrupt

•INTC interrupt-vector-transfer

Connections

•Via 25 pole sub-D connector on the front of the M-module

•Via 24 pole I/O connector on the i4000 for rear I/O (only on the i4000/P2 version)

•Via P1 to VMEbus

•Via VME-P2 connector (only on the i4000/P2 version)

Note: The P2 on an i4000/P2 can be used to create an alternative I/O-path for M-modules placed on the carrier board. The M-modules must support an alternative I/O-path (usually recognizable by a 24-pole female header near the DSUB-25).

IMPORTANT: The i4000/P2 cannot be used in a VMEbus rack with monolithic backplane or a P2/J2 backplane. For these cases use an i4000/NP2 instead.
