75D4-H2

3U cPCI Multifunction I/O Board, Gig-E Switch

The 75D4-H2 is a 3U cPCI I/O board that comes with a high-density I/O module slot pre-configured with the H2 Layer 2+ Gigabit Ethernet Switch module. This board operates at full 1000BASE-T speeds and consumes about 9.5 W of total power at 5V. In addition to the Ethernet switch, the motherboard also integrates four channels of RS232/423/422/485 serial communications. These channels can be accessed via the cPCI bus or optionally over Ethernet through one of the H2 switch ports.Thanks to its low-power consumption and high-performance capabilities, the 75D4-H2 is ideal for use in rugged defense, commercial aerospace, and industrial applications.
