01-W3914B Motorola | VME I/O Board, New Surplus

Description

Product Introduction

The Motorola 01-W3914B is a VMEbus board manufactured by Motorola’s Embedded Communications Computer Group, which later became part of Emerson Network Power and then Artesyn Embedded Technologies. VMEbus systems are widely used in high-reliability industrial applications including semiconductor manufacturing, medical imaging, defense systems, telecommunications infrastructure, and industrial automation. This board likely functions as an I/O interface, communications controller, or system processor within a VME-based embedded system.

Motorola was one of the largest suppliers of VMEbus single-board computers and I/O modules, with products such as the MVME series becoming industry standards. The 01-W3914B is part of this legacy product family. While VMEbus has largely been superseded by newer form factors, thousands of VME-based systems remain in operation, particularly in applications requiring long lifecycle support. For facilities still running Motorola VME systems, sourcing verified replacement boards is essential for maintaining operations without undertaking costly system migrations.

Key Technical Specifications

Due to the legacy nature of this module and limited public OEM documentation, we cannot provide a complete specification table without verifying the exact product type.

We recommend verification before purchasing.

Key Selling Points & Differentiators

• Legacy VME Support: Direct replacement for original Motorola VMEbus systems. Critical for facilities without a migration plan to newer embedded platforms.
• Application-Specific Verification: We work with you to confirm the board is appropriate for your specific VME chassis, backplane, and application before shipping.
• OEM Authenticity: Each unit undergoes visual inspection for Motorola OEM markings, serial number traceability, and PCB integrity. We do not sell counterfeit or refurbished units with unknown history.
• Tested for Functionality: We test every 01-W3914B on a compatible VME chassis or test system to verify communication, I/O operation, and system interface before shipping.
• Return Protection: If the board does not function in your system due to compatibility issues despite our verification, we offer return support to ensure you get the correct part.

Frequently Asked Questions (FAQ)

Q: What VME system is the Motorola 01-W3914B designed for?
The 01-W3914B is part of Motorola’s embedded VME product line. It may be:

• An MVME single-board computer (SBC) with processor and memory
• A VME I/O module with analog or digital I/O capability
• A communications controller for serial or network interfaces
• A custom board for specific OEM applications

To determine if this board fits your system, we need to know your VME chassis, backplane, and the role this board plays in your application.

Q: Is this board discontinued?
Yes. Motorola’s embedded computer group was sold to Emerson Network Power, and many VME products have been discontinued. Availability is limited to new surplus and tested used inventory. For VME-based systems still in operation, securing spares is essential.

Q: What is the difference between the 01-W3914B and similar Motorola VME boards?
Motorola used part number structures like 01-Wxxxx for various embedded products. Without original documentation, we cannot provide exact differences between variants. We recommend matching the full part number exactly to ensure compatibility, as different suffixes may indicate variations in processor speed, memory configuration, I/O options, or temperature range.

Q: Can I use this board in any VME chassis?
Not necessarily. VMEbus modules have specific requirements for:

• Form factor: 3U or 6U (this unit is likely 6U, but confirm)
• Backplane type: Standard VME, VME64, or VME320
• Addressing modes: A16, A24, or A32
• Data transfer modes: D08, D16, D32, or MBLT64

We can verify compatibility if you provide your chassis model and backplane specifications.

Q: Does this board require configuration before installation?
Most VMEbus modules require some level of hardware configuration for addressing, interrupts, or operating modes. The 01-W3914B likely has DIP switches or jumpers that must match your existing board’s settings. We recommend photographing your current board’s switch and jumper positions before removal and replicating them exactly on the replacement.

Q: What testing do you perform before shipping?
We test every 01-W3914B on a compatible VME chassis or test system. Our test procedure includes:

• Visual inspection for physical damage, corrosion, or previous repairs
• Edge connector cleaning and inspection
• Power-on test to confirm the board initializes without faults
• Communication verification with the VME backplane
• Functional test based on board type (I/O, processing, etc.)
• 24-hour continuous power-on soak test

A test report with test results is included with each shipment.

Q: How can I verify this is the correct board for my system?
Contact our technical support team with the following:

• Clear photos of your existing board (front, back, and edge connector)
• Your VME chassis make and model
• Any documentation from the original system integrator
• The application or machine type

We will cross-reference against our internal database of Motorola embedded products and help you confirm compatibility before shipping.
