6U cPCI D/S, S/D, I/O & Comm Board

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


NAI’s 78CS2 is a 6U cPCI Multifunction I/O and Communication Board designed for applications requiring Digital-to-Synchro/Resolver (D/S) stimulus output, as well as I/O and communication functions. This board contains five independent function module slots. The board can be configured for 10 D/S channels, or for D/S in combination with I/O and communication modules. Additional enhancements include FIFO data buffering for select modules. 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 78CS2, a low-power/high-performance board, is ideally suited for rugged defense, commercial aerospace, and industrial applications.

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 78CS2 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.


  • Support for 5 independent, intelligent function modules
  • Up to 10 D/S channels with:
    • On/off output capability
    • Individual reference inputs per channel
    • Rotation with start and stop angles
  • High efficiency D/S design requires less current from the power supply & substantially reduces heat generated on the CCA
  • FIFO data buffering for A/D, D/A, S/D, and LVDT functions
  • Programmable multi-speed ratio between 2 and 255 for S/D and D/S functions
  • Short circuit protection (standard); one of the outputs can be grounded without effecting performance
  • On board 5 VA programmable reference supply (optional)
  • Control via PCI Bus or Gigabit Ethernet (Gig-E) interface
  • Connections via front panel, rear panel, or both
  • Automatic Background Built-in-Test (BIT) (module dependent)
  • Software Support Kits (SSKs) and drivers available
  • Commercial and rugged models
  • Operating temperature: 0° C to 70° C commercial, -40° C to +85° C rugged
