Overview
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.
