Part Number 784804-01 is the National Instruments LV-222-442-442 PXI ARINC 429 Interface Module, designed to facilitate data transfer between commercial avionics systems based on the ARINC 429 standard. This module features 32 channels that can be configured as both transmitters and receivers, with automatic speed detection and detailed filtering capabilities for receive channels. Each channel can independently operate at low or high speeds of 12.5 or 100 Kbps, with the added flexibility to support non-standard speeds through software configuration. The 784804-01 is equipped with advanced generation capabilities and error detection functionalities, making it suitable for rigorous product development and testing environments. It can identify inter-message gap errors, bit count mistakes, and parity errors, while also enabling playback of stored data transmissions and the transmission of both asynchronous and periodic messages. Additionally, the module can monitor data streams and apply timestamps to received messages, ensuring precise data management. The unit interfaces through a PCIe connection, supporting transfer rates up to 2.5 Gbps in either direction, and is powered directly from the host PXIe slot, negating the need for an external power source. Integrated test circuitry allows for verification of module functionality and performance. Weighing 3.5 lbs and conforming to a standard 3U size, the 784804-01 is a versatile solution for ARINC 429 communications in aviation applications.
