Data Formats
There are three specific data formats:
UltraLyte (UL) format
20/20 format
Criterion format
The 20/20 and Criterion formats are combined in
a single menu selection.
In UL format, the instrument downloads speed
measurements in a format specific to the
UltraLyte family of speed detection instruments,
and downloads survey measurements in a
format identical to that of the Laser Technology
Impulse family of instruments.
The 20/20 format is identical to that of the Laser
Technology Marksman 20/20 speed detection
instrument. The 20/20 format is applied only to
speed/range measurements, and is provided for
those who already possess data collection
software for a 20/20 instrument.
The Criterion format is identical to that of the
horizontal vector message from the Laser
Technology Criterion family of survey
instruments. The Criterion format is applied only
to survey measurements, and is provided for
those who already possess data collection
software for the Criterion instrument family.
