KAD/EBM/104 ARINC 664 Part 7 Bus Monitor

The KAD/EBM/104 receives ARINC 664 Part 7 traffic on a dual redundant interface; redundant messages are removed before the stream is sent to a classifier which it then splits into two groups: parametric ARINC 664 Part 7 messages; and ARINC 429 over ARINC 664 Part 7. These are then parsed by type-specific parsers and made available across the Acra KAM-500 backplane. All parser slots are triple buffered; there are 256 parser slots for parametric ARINC 664 messages and 8192 slots for ARINC 429 messages.

The KAD/EBM/104 has two additional 100BASE-T ports that forward a mirror copy of all frames received after redundancy removal for transmission to packet recorders. Fragmentation of ARINC 664 Part 7 messages is not supported by the parser, but fragmented messages are forwarded by the relay output ports. It also supports redundancy removal and re-transmission for Ethernet fragmented frames.


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.
