Rugged Gig-E Switch - RESIU31

Configured with NAI's 75D4-H2 —
Gigabit-E Switch on a 3U cPCI board

NAI’s RESIU31 subsystem is configured with NAI’s 75D4-H2, a Layer 2+ Gigabit Ethernet (Gig-E) Switch built upon NAI’s multifunction, 3U cPCI board technology. Ideally suited for rugged military, industrial, and commercial applications, the RESIU31 delivers an off-the-shelf Ethernet switching solution that accelerates deployment of SWaP-optimized systems.

In addition, the 75D4 motherboard can integrate four channels of RS232/423/422/485 serial communications. Serial data is available on the cPCI bus or, optionally, via one of the Ethernet switch ports.
