Introduction
This chapter describes the data structure and
organization of the Leica GSI (Geo Serial Interface).
The GSI data structure is used for all data transferred
between the Leica electronic survey instruments, and
also defines the data stored internally. The following
information describes the data structure of the TPS1000
instruments and contains some specific features only
applicable to these instruments.
Data transferred between a Leica instrument and a
computer will conform to the GSI data structure (also
called GSI data format).
GSI storage format with
8 or 16 characters
From Version 2.20 onwards, there is a choice of two
GSI formats, with word lengths of 8 and 16 characters
respectively. When 16 characters are stored and
supported the following special conditions apply:
A measurement block is tagged with * at the first
position.
A data word includes the data at positions 7 to 23
instead of at 7 to 15.
