The KAD/UAR/102 is used to parse (coherently extract specific bytes) and snarf (send all data to a FIFO) up to four RS-232/422/485 channels.
- Monitors up to four RS-422/485/232 busses
- Coherently parses traffic and tags for up to 125 messages from 4 to 512 bytes
- 2K words deep per channel (snarfer)
- Bit-rates from 300bps to 1,000,000 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
- Receiving data from GPS module or onboard computer
KAD/UAR/102 4 Channel Universal Asynchronous Parser
The KAD/UAR/102 is used to parse (coherently extract specific bytes) and snarf (send all data to a FIFO) up to four RS-232/422/485 channels. The module is able to parse and snarf 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. The bit rates must be binary multiples of each other.
In the parser, a total of up to 126 complete messages are triple buffered so that the stale indication is message-wide. Each message can be up to 512 characters (bytes) long (including start and stop characters). Each message is tagged to 0.1 ms resolution; a message is considered found when up to eight specific bytes are received.
The end of the message byte is determined by a user-defined stop character or a specific number of words. A message is not updated if any sequence is incorrect.
The snarfer stores all data from each bus in a separate FIFO 2K words deep.
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.
