XDR - Transducer measurements
Measurement data from transducers that measure physical quantities such as temperature, force,
pressure, frequency, angular or linear displacement, etc. Data from a variable number of
transducers measuring the same of different quantities can be mixed in the same sentence. This
sentence is designed for use by integrated systems as well as transducers that may be
connected in a "chain" where each transducer receives the sentence as an input and adds its own
data fields on before retransmitting the sentence.
$--XDR, a, x.x, a, c--c, ........ a, x.x, a, c--c*hh<CR><LF>
Units of measure, transducer No. 1 (see note 2)
Measurement data, transducer No. 1
Transducer type, transducer No. 1 (see note 2)
NOTES
1 Sets of the four fields "type-data-units-ID" are allowed for an undefined number of transducers.
Up to "n" transducers may be included within the limits of allowed sentence length, null fields are
not required except where portions of the "type-data-units-ID" combination are not available.
