AT-XMC/PMC-DIO is a slave mezzanine card, providing x1 Lane PCI-Express interface or 32-bit PCI interface with the host system. It provides interface to different types of input and output signals for the avionics domain user interactions. The XMC/PMC discrete I/O boards are designed to provide users with a high degree of reliability and flexibility to meet input-output requirements. They are ideally suited for stringent military and airborne applications. AT-XMC/PMC-DIO has implemented all its discrete I/O logic in the FPGA. All discrete inputs and outputs are accessed through registers implemented inside the FPGA.

Discrete outputs can be used to switch +27V/GND/OPEN type loads. AT-XMC/PMC-DIO provides a total of 40 nos of discrete I/O interface to the PCI/PCIe bus. Twelve nos are +27V/OPEN type or casing break type inputs, eight nos are of Open/GND type inputs and an equal number of respective outputs. The card provides I/O interface through front panel mounted 68-pin PCB mount right-angled VHDCI receptacle connector or though rear XMC user I/O connector J16 or PMC I/O connector JN4 for accessing the I/O through back plane. On-chip timers are used for scheduled status reading of discrete inputs or drive of discrete outputs.

Software

The AT-XMC/PMC-DIO software includes Drivers & APIs. The product comes with a powerful set of library functions to access the entire DIO functionality. The drivers are designed in a modular fashion consisting of component functions and application functions. The user’s test program can be developed with few calls to the driver by using the set of application functions provided. Driver and high-level API libraries for Windows XP, Windows 7 and Linux are available. LabVIEW drivers available optionally.
