- Coherently parses traffic and tags for up to 4095 messages
- Aperiodic transmission of packetized ARINC-429 messages including tags as iNET-X parser-aligned payload structures
- Detects five types of errors
- Word counter for each bus
- ARINC-429 monitoring and recording
KAD/ABM/102 ARINC-429 Bus Monitor Parser/Packetizer/Accumulator
The KAD/ABM/102 is an ARINC-429 bus monitor which combines the capabilities of a coherent message parser with the flexibility of an iNET-X packetizer 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.
Every ARINC-429 message received from each of the eight busses is captured and packetized, along with time tags and a bus tag, with other received messages in a packetizer buffer. The packetizer contents can be assembled into Ethernet frames by an iNET-X controller or transmitter, for example a KAD/BCU/140, for transmission over Ethernet. The module can generate a single packet per input bus or packetize messages from all the active busses into a single packet stream.
To ensure efficient use of bandwidth, packets are only generated once a threshold amount has been stored (a maximum of 84 received messages are stored in each packet). Additionally, a programmable timeout ensures that smaller packets are generated even during periods of low activity on the bus, thereby allowing real-time analysis and processing of acquired messages. When there is no traffic, no packets are generated.
The KAD/ABM/102/EM1 extends the functionality of the KAD/ABM/102 by adding a 48-bit accumulation, which accumulates binary data from a user-defined ARINC-429 label.
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.
