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.

Getting the most from the
KAD/UBM/105
Each of the 12 bus connections can be independently
selected as RS-232, RS-422 or RS-485. For RS-232 (single
ended), use a DATA(x)+ pin and leave the corresponding
DATA(x)- pin unconnected. Both data pins are required when
a differential mode is selected (RS-422 or RS-485).
The following figure shows how to optionally terminate the
RS-422 and RS-485 receivers by using the internal
termination resistor provided on the module (TERM[x] pin). It
is important to ground each source of RS-232, RS-422 or
RS-485. Star grounding provides optimal noise rejection. For
details on grounding, see TEC/NOT/063 - Grounding and shielding of
the Axon and Acra KAM-500.
Figure 2: Optional RS-422/RS-485 third pin termination
Maximum message length
The maximum message length is 1,024 bytes. This length
includes the bytes used for the start pattern and the end byte
(if an end byte is used).
Parser Data Endianness example
With ABCD characters being transmitted, setting Parser Data
Endianness to:
First byte at low end of word - module outputs DW0 = AB and
DW1 = CD
First byte at high end of word - module outputs DW0 = BA
and DW1 = DC
Error codes
Parser slot count
If any channel is configured with a rate higher than 1 MHz, the
total number of parser slots that can be set up is reduced as
shown in the following table.
Packetizer format
The KAD/UBM/105 recognizes bytes as having a start bit,
data bits (seven or eight, programmable), a parity bit
(optional), and a stop bit. The KAD/UBM/105 gathers groups
of bytes into standard iNET-X parser-aligned blocks. Each
output packet can contain multiple blocks. If configured to
receive 7-bit bytes, each byte is padded to 8 bits using a zero
at the most significant bit before saving. The generalized
iNET-X payload structure for parser-aligned packets is shown
in Figure 3 on page 8 and examples of parser block formats
are shown in Figure 4 on page 9.
A parser block is created for each logical message, based on
the gaps between sequences of bytes. A new parser block is
created at the start of each iNET-X packet and also when the
time gap between successive bytes exceeds a programmable
threshold.
The gap time threshold is programmed in characters. By
setting the threshold value to just under the minimum gap
time allowable between messages (under the protocol being
used), it is possible to correctly split the bytes of the incoming
stream into individual messages, as required. If multiple
messages are received back-to-back, in a burst with no such
gap, they are packetized as a single message. Conversely, if a
single message continues past the end of one packet with no

gap, the succeeding bytes are packetized in a new parser block in the next packet. A bit in the header of the first parser block, in
the following packet, is set to indicate that this block is a continuation of the message in the final block of the previous packet.
The location of this continuation bit is marked Cn in the example parser blocks in Figure 4 on page 9.
If a 0 μs threshold is set, gaps are not detected, and in the absence of errors, each iNET-X packet contains a single parser block
whose length is controlled by the packet timeout and size settings selected.
The Error Code field for the parser block indicates whether any error was detected.
If parity error detection is enabled, the parity bit for each byte is checked but not recorded. If error reporting is enabled, the error
code is reported in the parser block header, and optionally, an extra quadbyte can be suffixed to the parser block indicating the
byte offset of the first error. There may be additional errors at locations past this offset.
NOTE: Additional packetized messages that contain one zero value byte can occur when there is noise on the incoming signal
lines. These may be marked as errors, depending on the parity and error detection settings.
