Appendix B: Data Output Format
Serial Data
Output Format The values transmitted via the serial connection are shown below.
Output occurs every 1 second. Values are tab delimited and each line
is terminated with a <CR><LF>. Data saved by LISST-Tau software
will be a TXT file in this format.
The LISST-Tau supports other special-purpose data formats, which are
not described here. Contact Sequoia Scientific for details.

1 ID
Identifies instrument
“LTAU<SN>”. SN is a 4-digit
number (1234 in example) followed by one character
indicating a model variant, G for 532 nm or R for 650
nm).
