The composition of the basic data set depends on the variant (with / without pyrometer) of
the actual device (see below).
Due to the applied measurement processes the NIRS31-UMB will, different from other
sensors described in the SDI-12 document, always measure continuously. During certain
phases of the measurement process the availability of the device for communication is
limited. This causes some special properties:
The device
does not need a “Wakeup” and does not have a sleep mode. So the
reactions to “Break” signals and any related timings are inapplicable. “Break” will be
ignored by NIRS31-UMB.
M- and C- commands only differ in the number of values made available in the
buffers (in both cases up to the maximum permitted by the standards of 9 resp. 20).
R-Commands are not available.
