KAD/CBM/103 4 Channel CCDL/MCDL Monitor
The KAD/CBM/103 extracts valid CCDL/MCDL messages from incoming serial streams. It coherently extracts certain words from these messages and saves them to specified locations in the telemetry frames (parser). The KAD/CBM/103 parses CCDL/MCDL bus traffic and tags each message for up to four CCDL/MCDL busses. It combines a coherent message parser and a message counter with error detection functions in a single module.
In the data sheet, traffic refers to bytes on the bus and tags refer to associated information such as microsecond time of the last byte in the message, message count, and errors.
The parser triple buffers up to 127 unique complete messages per bus and their associated tags. The INFO tag associated with each message has a STALE bit (message read before) a SKIPPED bit (buffer overwritten) and an EMPTY bit (message was never received). MsgCnt increments on receipt of a valid message. The REPORT word contains bits that indicate an error has occurred, and on which bus it has occurred.
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.
