The KAD/ABM/101 is an ARINC-429 bus monitor, which combines a coherent message parser with an all-pass/selected-pass snarfer FIFO.
- Monitors up to eight ARINC-429 busses
- Coherently parses traffic and tags for up to 4,095 words
- 64K deep selective First In First Out (FIFO) for traffic and tags (snarfer)
- Word counter for each bus
- Detects six types of errors
- ARINC-429 monitoring
- Translation from one bus to another
KAD/ABM/101 ARINC-429 Bus Monitor Parser/Snarfer
The KAD/ABM/101 is an ARINC-429 bus monitor, which combines the capabilities of a coherent message parser with the flexibility of an all-pass/selected-pass snarfer FIFO and an error-detection function, on a single module.
The parser parses up to 4,095 words and their associated time and status tags. Each message has a stale bit (word read before) and a skipped bit (buffer overwritten). Messages can be parsed based on their bus number, label, SDI, and/or SSM fields.
The snarfer stores selected traffic and tags in a FIFO, 64K words deep. Each word has 16 bits for traffic tag information and 7 bits for FIFO content identification. Data selection and content identification is based on the Bus (0 to 7), ARINC traffic, tag type (time high/low/micro and message count), and how full the FIFO is.
The word count increments on receipt of a valid word. The report word has bits indicating the type of error caught and the bus it occurred on.
Aerospace Instrumentation Brochure
Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
