5.2 To Define the Data Sample(s) to be Recorded
The SpaceLogger.S10 is capable of being used with any sensors that output their information in
ASCII sentences. The format of the data must be 8 bits and no parity. It is also a requirement that
each data record has identifying start and end characters to define the data sequence to be sampled.
Up to two different data samples may be defined. By default just one sample is recorded, defined
by STX (start) and ETX (end) identifiers.
The start and end identifiers may be defined in one of two ways; either a single ASCII character
specified by its decimal value (0-255) or by a string of up to 31 characters contained by quote
marks.
The SpaceLogger.S10’s default start character is <STX> (2) and end character is <LF> (10).
The SpaceLogger.S10 may be set to recognise any other start and end characters using the
following SETUP.TXT command lines:
STX=x or
STX=“cc…”
ETX=x or ETX=“cc…”
Where:
o
x is the decimal value (0-255) of the ASCII character that indicates the start (STX)
or end (ETX) of the data string that is to be stored. Default value for STX is 2.
Default value for ETX is 10. *
o
cc… is a string of up to 31 ASCII characters
Note:

The string is case sensitive.

Question marks (?) may be used to denote any character i.e. as wildcards.

The following escape codes may be included in the STX and ETX strings:
\n = 0x0A LF
\r = 0x0D CR
\" = 0x22 "
\' = 0x27 '
\\ = 0x5C \
\1 = 0x01 SOH
\2 = 0x02 STX
\3 = 0x03 ETX
\4 = 0x04 EOT
\5 = 0x05 ENQ
\6 = 0x06 ACK
\7 = 0x07 BEL
\a = 0x07 BEL
\b = 0x08 BS
\f = 0x0C FF
\t = 0x09 HT
\v = 0x0B VT
