The National Instruments 784802-01 PXI ARINC 429 Interface Module, identified by the model number LV-222-441-000, is designed to facilitate the transfer of digital data between commercial avionics systems in accordance with the ARINC 429 standard. This module features eight channels, each configurable as both a transmitter and receiver. The receive channels are equipped with automatic speed detection, independent label, and Source Designator Identifier (SDI) filtering, while the transmit channels can accurately maintain label repetition rates. Each channel supports low or high-speed operation at 12.5 or 100 Kbps, respectively, and also allows for the configuration of non-standard frequencies via a bit-rate configuration function, enabling interoperability with non-compliant equipment.

The 784802-01 offers extensive data generation capabilities and advanced error detection features, making it an optimal tool for product development and testing. It can detect parity bit errors, bit count errors, and inter-message gap errors, while supporting the transmission of both periodic and asynchronous messages, alongside the ability to playback recorded data streams. The module can timestamp received messages and interfaces via a PCIe connection, supporting transfer rates of 2.5 Gbps. It draws power directly from the host PXIe slot, eliminating the need for an external power supply. Additionally, it includes integrated test circuitry to verify card functionality, ensuring the device operates as intended. While it does not support parametric waveform control or output state control, the 784802-01 presents a robust solution for ARINC 429 communication needs. The module conforms to a standard 3U size and weighs 3.5 lbs.
