6U OpenVPX Multi-function I/O

Model OpenVPX 67C3

The 67C3 is a single slot 6U OpenVPX (0.8” pitch) multi-function I/O and serial communications board.

With VME, Gigabit Ethernet (Gig-E) and High Speed sRIO or PCIe control interface selections, users can confidently choose to take advantage of the OpenVPX form-factor offering higher speed switched fabric communication options.

The motherboard contains six independent module slots, each of which can be populated with a function-specific module, and can now be controlled by the VME, Gig-E and sRIO or PCIe. This enhanced motherboard, using multiple DSPs, allows for higher processing power and dedicated pre-processing control for each module function. This unique design eliminates the need for multiple, specialized, single function cards by providing a single board solution for a broad assortment of signal interface modules.

In addition, the 67C3 incorporates serial communication modules such as RS232/422/423/(188C)/485, MIL-STD-1553, CANBus and ARINC429/575.This approach increases packaging density, saves enclosure slots and reduces power consumption. Additional enhancements include FIFO data buffering for A/D, D/A, S/D and LVDT functions, and fully programmable, continuous background Built-in-Test (BIT).

A Wind River® VxWorks® Software Support Kit (SSK), including source code to build a board specific library, is supplied to facilitate function implementation independent of user's Single Board Computer (SBC).
