The KAD/UBM/105 is a 12-channel serial 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.
- Monitors up to 12 RS-422/485/232 busses
- Coherently parses traffic and tags for up to 511 messages from 4 to 1024 bytes
- Aperiodic transmission of packetized serial messages including tags as iNET-X parser-aligned payload structure
- Bit-rates from 300 bps to 5,000,000 bps
- 7/8 bits per word with odd, even or no parity
- Programmable start sequence (1 to 8 bytes), stop sequence (1 byte or by fixed length) and idle time
- Interfacing with serial data links
KAD/UBM/105 12 Channel Serial Bus Monitor Parser
The KAD/UBM/105 is used to monitor up to 12 RS-232/422/485 channels. The module can parse (coherently extract specific bytes) and/or packetize (insert messages in packets for Ethernet transmission) each channel at the same time.
The signal type (RS-232/422/485), bits per word, and parity are programmable on a channel-by-channel basis.
In the parser, a total of up to 511 complete messages are triple buffered so that the stale indication is message-wide. Each message can be up to 1,024 characters (bytes) long (including start and stop characters). Each message is tagged to 0.1ms resolution; a message is considered found when a start sequence of up to eight specific bytes is received. The end-of-message delimiter is determined by a user-defined stop character or after a specific number of words are received. A message is not updated if any sequence is incorrect.
Independently of the parser, an iNET-X packet stream is generated for each channel. All received bytes are encapsulated in an iNET-X parser-aligned payload structure. A programmable gap time allows the module to split the incoming bytes into shorter timestamped sequences. A block header attached to each sequence stores the channel index, length, and the time of reception of each message. These parser-aligned packets may be transmitted aperiodically to optimize network bandwidth utilization and memory usage when recording serial traffic.
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.
