Functional Features:
- Comprehensive I/O Integration: Consolidates a PCI-to-ISA bridge, ultra-wide SCSI adapter, and Super I/O functions into a single PMC-form-factor board.
- Advanced Signal Processing: Capable of amplifying, filtering, and correcting input signals, alongside precise control and regulation of output signals.
- Backward Compatibility: Fully supports legacy Motorola Computer Group (MCG) products, allowing seamless integration with older MVME761 and MVME712M transition boards.
- Extensive Protection Mechanisms: Built-in overvoltage, overcurrent, and thermal protection safeguards both the module and connected equipment.
Application Scenarios:
Widely deployed in industrial automation, robotics control, telecommunications infrastructure, smart home systems, medical equipment, and aerospace applications requiring high-performance signal processing and reliable control.
Performance Parameters:
- Maximum Output Current: +12VDC at 40A, -12VDC at 40A, +3.3VDC at 10A
- Operating Temperature Range: -40°C to +85°C
- SCSI Controller: LSI Logic SYM53C895A operating at a 40 MHz clock frequency
- PCI Interface: 32-bit PCI interface via connectors P11 through P14
Material Composition:
Constructed using industrial-grade printed circuit boards with high-reliability electronic components. The module features a ruggedized design optimized for electromagnetic compatibility (EMC) and thermal stability under continuous high-load operations.
Structural Characteristics:
- Form Factor: Single-width, standard-length, standard-height PMC (PCI Mezzanine Card) board.
- Connectors: Features four EIA-E700 AAAB connectors for host board interfacing, along with specific I/O routing through P14 and P15 connectors.
- Indicators: Equipped with dual LED indicators (SCSI LED and PIB LED) to provide real-time visual status of device activity and bus arbitration.
Working Principle:
The module acts as an intelligent intermediary, utilizing an onboard Winbond PCI-to-ISA bridge and LSI SCSI controller to manage data traffic. It routes specific signals (such as narrow SCSI, parallel ports, and synchronous serial ports) through the P14 connector to the host board, while routing remaining SCSI data lines through P15. In IPMC mode, it translates modern PMC I/O signals to be compatible with legacy rear transition modules.
Installation Requirements:
- Host Compatibility: Must be installed in PMC Slot 1 of compatible base boards such as the MVME6100, MVME5500, or MVME5100.
- Configuration: The base board must be configured (via jumpers) to support IPMC mode when utilizing this module.
- Physical Mounting: Ensure the PMC board is perfectly aligned with the host board’s standoffs and securely fastened using appropriate hardware to prevent vibration-induced disconnections.
