The Curtiss-Wright/Systran SCRAMNet GT200 PCI-X card delivers high-speed, deterministic data communication for real-time distributed systems. Built on replicated shared-memory architecture, it transfers data across multiple computing platforms with sub-microsecond latency. The card consolidates network control and data streams into a single 2.5 Gbit/s link, eliminating multiple network interfaces and enabling complex simulations, data acquisition, and distributed control without compromising performance.
## Technical Specifications
• **Data Throughput:** Exceeds 210 MB/s
• **Data Transfer Rate:** 2.5 Gbit/s
• **System Latency:** Sub-microsecond
• **Shared Memory:** 128 MB dual-port

• **Host Interface:** PCI-X (33 MHz/66 MHz, 32/64 bit); PMC format available
• **Optical Media:** Industry-standard SFP transceivers
– Short wavelength (850 nm): 250 m maximum
– Long wavelength (1300 nm): 10 km maximum
• **Signaling Voltages:** 3.3 V or 5 V PCI
• **Memory Buffering:** Insertion and transmit/receive FIFOs prevent data collisions
• **Interrupts:** Selectable local host interrupts; broadcast and unicast network interrupts for node synchronization
## Key Features
• Concurrent network and host memory access without flow control overhead
• Multiple transceiver options: shortwave multi-mode and longwave single-mode with optional redundancy
• Available in standard and conduction-cooled rugged form factors
• Operates with LinkXchange family switches (2.5 Gbps or faster)
• Cross-platform interoperability across diverse computing architectures
## Operating System Support
Linux, Windows, VxWorks, Solaris, RTX, IRIX, MATLAB, and LabVIEW.
## Compatibility & Integration
Variations interoperate completely on the link interface, functioning as a unified multi-processor system regardless of host platform. The architecture supports both broadcast and unicast signaling for distributed control and synchronization across networked nodes.
