Operation
characters are replaced by underscores (“____”). In kinematic surveying it is
common to change the site ID many times during the recording session. The
site ID used for naming the session files is the LAST site ID entered during
the session.
• The next character indicates the session identifier. This field automatically
increments from A to Z when a new recording session is started. This field
begins at A for the files associated with the first recording session within a
particular work day directory, and increments to Z as more sessions are
created in the same directory. After 26 files are created the session identifier
resets back to A, and the first character of the year will change to A.
• The next two characters are the last two digits of the year (e.g. 97).
• The file extension is the day of the year (e.g. Jan. 1 is day 001; Dec. 31 is day
365).

ATA MODES
There are three different modes that the receiver can record in. These modes are
referred as data modes or data types. Each mode records different types of data and
can only be changed using the serial port command $PASHS,RNG. Table 2.2
describes these modes. The default is 0.
Data Logging through Serial Port
An alternative way to record data is to record data directly onto your PC. This method
is useful if your data card does not have enough space or if you wish to bypass the
download process. To record data directly onto the PC, use the DATALOGR.EXE
program. DATALOGR will collect B and E-files in real time onto your computer.
Data logging through a serial port is also possible with Z-Sensor and Z-Eurocard.
