Data Recording; Setting The Data Recording Interval; Data Modes - Thales Z-Max Operation And Application Manual

Data Recording

All data recording in the receiver is done on a removable SD memory card that is
installed in the receiver. The amount of data that can be stored depends upon the size
of the card. The Z-Max standard memory card size is 64 Mb. Larger cards are
optional.
Data recording to the SD memory card is automatic if the card is correctly inserted in
the SD card slot, correctly formatted, and the receiver is tracking satellites. Optionally,
the user can change a variety of data collection parameters including the recording
interval, the data-recording mode, the site name, the elevation mask, and the
minimum number of satellites tracked before recording data. While data is recording
on the SD memory card, the Data Log LED will flash green for each epoch recorded,
indicating that the SD memory card is actively in use. If the receiver memory fills up
and is not able to log any more data to the SD memory card, the LED will go to
constant red. If the SD memory card is full, you can either delete old files from the
card using the SESSIONS menu of the front panel user interface, or else put in a new
card.
It is important to power off the receiver using the Power key on the Front Panel before
removing the SD card. Also, reformatting the SD card every two weeks during
constant use is recommended. See "Reset the Unit" on page

Setting the Data Recording Interval

The default recording interval is 20.0 seconds. The data recording interval can be
changed from the front panel LED display (in the SURVCONF submenu) to any value
between 0.1 and 999 seconds. Recording interval can also be controlled by entering
text based commands through the serial port of the Z-Max. Refer to Appendix B for
the formats of many common serial commands.

Data Modes

The Z-Max receiver can record data in 5 different modes, called Data Recording
Modes. The modes available are Data Modes 0, 2, 4, 5, and 6. The Z-Max
automatically sets the receiver to record data in the data mode which best fits the type
of surveying being done. The Z-Max can be explicitly set to record in any data mode
by entering text commands through the serial port (see Appendix B).
