KAD/UAR/102 RS-232/RS-422/RS-485 universal asynchronous parser and snarfer - 4 channels
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 message byte is determined by a user-defined stop character or 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.
