Functional Role in VME Systems

Rather than acting as a processing unit, the VME-PMC-CADDY serves as an expansion and mounting solution. It enables flexible system configuration by allowing PMC modules—such as communication, data acquisition, or I/O cards—to be securely installed and connected within VME platforms.

Common usage scenarios include:

• VME systems requiring additional I/O channels

• Embedded control platforms with modular expansion needs

• Defense and aerospace systems using PMC-based peripherals

• Industrial automation systems with customized interface requirements

Mechanical Structure and Components

The module features a rugged mechanical frame designed to securely hold PMC cards during operation. Precision-aligned connectors ensure stable electrical contact, while the structural design supports resistance to vibration and mechanical stress often found in industrial and mission-critical environments.

Key structural elements include:

• PMC card mounting frame

• High-quality electrical connectors

• VME-compatible mechanical interface

• Reinforced structure for long-term durability
