The Ballard Technology LP429-3 is a flexible, powerful, ARINC 429 avionics databus interface board for the development and maintenance of commercial avionics. Installed in a PCI computer, users can transmit and receive messages on up to eight databuses. Several mixes of transmit and receive channels are available and units can be upgraded at any time to meet changing requirements. The advanced features, ease-of-use, and upgrade paths make the LP429-3 an ideal solution for ARINC 429 hardware and system development, testing, and simulation.

The LP429-3 can be easily configured to automatically transmit and receive labels (ARINC 429 words) while saving a sequential record of messages. The host computer can read or write data, alter transmit labels, or read receive labels at any time without interfering with the operation of the LP429-3. Transmissions are automatically maintained at the specified transmit intervals and may include concurrent aperiodic labels for file data transfer protocols. Received data is filtered by label and SDI (source/destination identifier) and saved according to user specifications.

The sequential record is a time-tagged history of databus activity that can be saved for later analysis. The user specifies which labels go in the sequential record and what other performance information is to be recorded.


Once configured, the LP429-3 hardware can transmit, receive, and build the sequential record without requiring any processing by the host computer. The onboard, high-speed DSP, large memory, and custom gate arrays provide power and flexibility for the multitude of LP429-3 features and user options.
