The memory configuration has 128MB or 256MB SDRAM on board and supports parity function to ensure data integrity. Memory access latency is as low as 0.4 microseconds with support for dynamic packet sizes (4 to 64 bytes).Interface and bus compatibility PCI bus: Supports 32-bit/33MHz or 64-bit/66MHz configurations and is compatible with 3.3 V and 5.0 V logic levels. Optical fiber interface: the transmission distance of multimode optical fiber is up to 300m, and the single-mode optical fiber supports 10km; the baud rate is 2.125 Gbps.Peak bandwidth of transmission performance: 174MB/s (64-byte burst transmission). Standard transfer rate: 43-170MB/s (non-redundant mode), 20-87MB/s in redundant mode. Redundant mode: support dual-channel data transmission to improve network reliability.The network topology supports ring and star networking structures. The ring topology requires all nodes to be powered on to achieve deterministic latency, and the star topology bypasses failed nodes through reflective memory hubs.Physical characteristics Operating temperature: 0 ° C to + 65 ° C (forced air cooling) Storage temperature range: -40 ° C to + 85 ° C. Power consumption: 5V DC power supply, typical value 1.5A, maximum value 1.8 A. Dimensions: Standard PCI half-length card design.Other functions DMA channel: Two independent DMA engines, supporting large data block split transfer. Interrupt function: Support 4 general network interrupts, each interrupt can carry 32-bit data. Big and small end conversion: adapt to different CPU architectures (such as ARM, PowerPC, etc.).
