MOTOROLA MVIP301 IndustryPack Serial Communication Module

MOTOROLA MVIP301 IndustryPack Serial Communication Module

Introduction

The MOTOROLA MVIP301 is a high-density, intelligent serial I/O module designed under the IndustryPack (IP) architecture.

It serves as a mezzanine expansion board that can be mounted on various VME, PCI, or CompactPCI carrier boards.

The MVIP301 is specifically engineered for industrial applications requiring multiple high-speed serial channels with flexible protocol support.

Unlike standard serial cards, the MVIP301 provides a modular and space-efficient way to add communication ports to a larger system without occupying additional backplane slots.

It is a critical component for legacy and high-reliability systems in the telecommunications and industrial control sectors.

The MVIP series offers different configurations based on port density and physical interface:

MOTOROLA MVIP302: 8-channel asynchronous serial module (EIA-232).

MOTOROLA MVIP303: 8-channel asynchronous serial module (EIA-422).

MOTOROLA MVIP340: Digital I/O module with two MC68230 timers.

Application Cases

Distributed Control Systems (DCS): Used as a communication bridge to link legacy serial sensors and actuators to a modern VME-based central controller.

Telecommunications Gateways: Handles synchronous data streams for network signaling and protocol conversion in legacy switching systems.

SCADA Systems: Integrated into Remote Terminal Units (RTUs) for reliable serial data polling across vast industrial utility networks.

Military & Defense: Employed in shipboard or ground-based systems where high-reliability, multi-protocol communication is required in a small footprint.

Product Advantages and Features

Mezzanine Versatility: Its IndustryPack design allows it to be swapped between different carrier architectures (VME to PCI) without changing the core software logic.

Multiprotocol Capability: Supports both RS-232 and RS-422. allowing users to mix and match hardware interfaces within the same system.

High Efficiency: Offloads serial processing from the main CPU, reducing system overhead and improving real-time performance.

Compact Footprint: Fits into the “Single IP” slot size, enabling high-density I/O configurations on a single 6U VME board.

Other Models in the Same Series

MVIP-IO: General-purpose digital input/output modules.

MVIP-ADC: Analog-to-digital conversion modules for sensor data acquisition.

MVIP-DAC: Digital-to-analog modules for motor and valve control.

Installation and Maintenance

Installation: Align the 50-pin female connectors of the MVIP301 with the male pins on the IP carrier board (e.g., MVME162).

Press firmly until seated and secure with mounting screws. Warning: Always disconnect power before seating or unseating modules to avoid damaging the CMOS components.

Jumper Configuration: Some variants require hardware jumpers to be set for RS-232 vs RS-422 selection. Refer to the carrier board manual for specific memory address mapping (A16/A24/A32).

Maintenance: Check for oxidized pins on the 50-pin interface if intermittent communication occurs. Use anti-static (ESD) handling procedures at all times during maintenance.

Unique Product Description

The Motorola MVIP301 is a masterclass in modular industrial design. By condensing two powerful,

multiprotocol serial engines into a tiny IndustryPack footprint,

Motorola provides engineers with the ultimate tool for system expansion.

Whether you need to support synchronous high-speed data or standard RS-232 terminal connections, the MVIP301 delivers robust, industrial-grade reliability.

It is an essential spare part for maintaining the longevity of VMEbus systems, ensuring that critical communications remain uninterrupted in even the most demanding environments.
