SCRAMNet GT Distributed Shared-Memory Networking

The SCRAMNet GT architecture supports data sharing between interconnected computing systems. Its distributed shared-memory approach is suitable for applications requiring coordinated communication between multiple processors and computing platforms.

128MB Shared Memory

The H-AS-GPM128SC-20 incorporates 128MB of shared memory, allowing compatible host systems to exchange information through the SCRAMNet GT network. The module supports concurrent access by the local host and network interface.

850nm Fiber-Optic Communication

This configuration includes one 850nm short-wavelength pluggable optical transceiver. The fiber-optic interface supports communication between compatible SCRAMNet GT network nodes.

PMC Interface and System Integration

The module uses a 66MHz PCI-based PMC interface for integration into compatible single-board computers and embedded computing platforms. Host compatibility, PMC electrical requirements, software drivers and SCRAMNet GT network configuration should be verified before installation.

Typical Applications

• Real-Time Distributed Computing
• Industrial Automation and Control
• Hardware-in-the-Loop Simulation
• Test and Measurement Systems
• Aerospace and Defense Computing
• Legacy SCRAMNet GT Network Maintenance

Replacement and Compatibility

When replacing an existing SCRAMNet GT200 module, verify the complete manufacturer part number, shared-memory capacity, PMC interface requirements, optical transceiver wavelength, network topology and software compatibility.

The H-AS-GPM128SC-20 is specifically configured with a single 850nm optical transceiver. Other GT200 variants may have different optical media configurations and should not be treated as direct replacements without technical verification.
