The Curtiss-Wright/Parvus PRV-1059-02 is a 5-port PC/104 Fast Ethernet switch engineered for embedded systems operating in harsh, demanding environments. This unmanaged switch delivers 10/100 Mbps connectivity through five auto-crossover RJ-45 ports, operating as either a standalone unit or integrated directly into PC/104 (ISA) bus architectures. Qualified to MIL-STD-810 environmental standards, it sustains operation across -40°C to +85°C and withstands 20 Gs shock and airframe vibration profiles without performance degradation.
