3U cPCI I/O & Comm Board

Three I/O and communication function module slots—
A variety of modules to choose from


NAI’s 75C5 is a 3U cPCI Multifunction I/O and Communication Board with three independent function module slots. Two of the slots can be configured with a variety of I/O and communication functions; the third, with either a combination module featuring four multiplexed Analog-to-Digital (A/D) channels and 28 Discrete I/O programmable channels, or with a reference power supply. Using multiple DSPs, the enhanced motherboard enables higher processing power and dedicated pre-processing control for each module.

By eliminating the need for multiple, specialized, single-function boards, this unique design increases packaging density, saves enclosure slots, and reduces power consumption. The 75C5, a low-power/high-performance board, is ideally suited for rugged defense, commercial aerospace, and industrial applications.

In a PCI chassis, the external host processor acquires sensor measurement data and controls simulation signals from the 75C5 via the VME Bus or Gigabit Ethernet (Gig-E) port. Preexisting, fully-tested functions can be quickly and easily combined in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.

The 75C5 includes Software Support Kits (SSKs) for multiple operating systems. In addition, SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
