Working Principle As a VME bus host board, it runs control programs and performs logic calculations through the built-in Celeron processor, exchanges data and control signals with other VME modules via the VME backplane, and outputs operation instructions to drive peripheral industrial devices.
Installation Requirements
- Insert into a standard 6U VME chassis slot
- Ensure the backplane connector is fully inserted and locked
- Connect chassis grounding wire for electrostatic protection
- Maintain unobstructed ventilation around the board
Usage Notes
- Power off the chassis before inserting or removing the board
- Wear an anti-static wrist strap during handling to prevent ESD damage
- Do not input voltage exceeding the rated range
- Clean connector contacts regularly to ensure signal transmission quality
