Introduction

The MOTOROLA MVME335 is a robust and versatile I/O expansion module designed for the VMEbus architecture.

It provides a critical link for VME-based systems that require multi-channel serial communication and parallel printing capabilities.

As a high-reliability interface board, the MVME335 is commonly used to connect VME single-board computers (SBCs) to external peripherals such as terminals,

modems, and printers, making it a staple in legacy industrial control and data acquisition systems.

Installation and Maintenance

Installation: Insert the MVME335 into an available 6U VME slot. Ensure the board is properly seated in both the P1 and P2 backplane connectors.

Use the captive front-panel screws to secure the module against vibration.

Jumper Settings: Consult the technical manual to configure the board’s address map before powering on the system, as conflicting addresses can cause system-wide bus errors.

Maintenance: This is a low-maintenance board.

Periodic inspection for dust accumulation around the connectors and checking the tightness of external DB-connectors is recommended to ensure signal integrity.

Unique Product Description

The MOTOROLA MVME335 is the “Swiss Army Knife” of VMEbus I/O.

While modern systems have moved toward USB and Ethernet, the MVME335 remains essential for maintaining the operational life of mission-critical legacy infrastructure.

Its ability to provide stable, hardware-level RS-232 and Parallel connectivity without the overhead of complex network protocols makes it the gold standard for reliable industrial communication.
