Description
The Motorola MVME 333-2 is a 6-channel intelligent serial communication controller board designed for VMEbus systems. VMEbus, short for Versa Module Eurocard bus, is an older standard for modular computer systems used in industrial automation and embedded applications. Here’s a breakdown of the MVME 333-2’s functionalities:
Core Function:
- Enables communication between a VMEbus system and multiple serial devices using its six intelligent serial communication channels. Serial communication is a common method for data exchange between devices in industrial settings.
Features (based on available information):
- 6 Serial Ports: Provides six independent RS-232 or RS-422 serial ports for connecting to various serial devices like sensors, actuators, and terminals.
- Intelligent Channels: These channels might offer features like:
- Baud rate configuration (data transmission speed)
- Parity control (error detection)
- Flow control (regulating data flow between devices)
- Interrupt handling (signaling the CPU for attention when data arrives)
- Depending on the specific model revision, additional functionalities might be available.
Applications (historical):
- Industrial Automation Systems: Facilitating communication between VMEbus-based controllers and serial devices used in industrial processes like sensors, programmable logic controllers (PLCs), and Human-Machine Interfaces (HMIs).
- Embedded Systems: Offering serial communication capabilities for data exchange or remote access in VMEbus-based embedded systems.
Availability and Use Today:
- The MVME 333-2 is likely an older product and might be difficult to find new.
- VMEbus itself is a legacy standard. While some legacy systems might still be in operation, newer industrial systems typically use modern communication interfaces like USB or Ethernet.
Finding More Information:
- Limited Resources: Due to the product’s age, finding comprehensive information online might be challenging. Here are some potential resources:
- Online Marketplaces: Used electronics marketplaces might have listings for the MVME 333-2, which could include product descriptions or manuals (availability not guaranteed).
- Motorola Documentation Archive (uncertain): Motorola might have an archive section on their website for older products. However, the existence and accessibility of such resources are uncertain.
Additional Considerations:
- Legacy Standard: VMEbus and the MVME 333-2 are suited for maintaining or repairing legacy systems, not ideal for new projects.
- Modern Alternatives: Modern industrial systems typically use USB or Ethernet for communication, offering easier integration and faster data transfer speeds.
- Driver Compatibility: Driver software might be needed for the operating system running on the VMEbus system to interact with the MVME 333-2. The availability and compatibility of drivers depend on the specific model revision and operating system.
If you’re looking for a serial communication solution for a modern system, using a USB to serial adapter or a device with built-in USB or Ethernet ports would be a more suitable choice.
