Overview

TechSAT ARINC 429 PMC Interface Card

The TechSAT A429-PMC  is a powerful, multichannel ARINC 429 interface implemented on a PMC (PCI Mezzanine Card) form factor module. It has been specially designed to comply with high-performance test and simulation requirements where the ARINC 429 bus is used.

The A429-PMC features a fully parallel hardware design with strictly independent Tx-/Rx-channel state machines. The dual global FIFO host interface allows for extremely simplified and accelerated board access. The fully autonomous hardware implemented Tx-scheduler and the Rx-FIFO handler relieve any host platform from realtime tasks. Receive time stamping and error detection are also implemented in hardware.

The A429-PMC is equipped with comprehensive test features such as error injection/detection. Galvanic isolation, bidirectional discrete I/O lines, IRIG-B input and conformal coating are available as an option.

A429-PMC is supported by TechSAT’s ADS2 (Avionics Development System - 2nd Generation) which is used as a software platform in numerous test and integration environments. In addition the A429-PMC is based on the unified TechSAT Software Environment Interface architecture that can be found on various other TechSAT interface products. The A429-PMC comes with driver and interface library for Microsoft Windows 2k/XP/Vista, Linux and VxWorks.
