Ring Buffer

Overview

A ring buffer
• is a second set of raw data recorded in addition to the logging defined in CONFIGURE
Logging of Raw Obs.
• can use a different observation rate.
• has a defined duration for how long raw data is recorded.
• consists of several files.
• can be configured and used from an external software using special commands from
Outside World Interface or Leica Binary 2 format. Documentation for OWI and LB2 is
available on request from the Leica Geosystems representative.
• can be configured on the RX1210.
• has a number.
Ring buffers are used for monitoring an event.
Example: Data is collected for earthquake monitoring. The standard data is logged every
10 s and is continuously stored. The raw data for the ring buffer is logged at 1 s. After an
hours worth of raw data, for example, the ring buffer file is ovewritten by a new ring buffer
file. If an earthquake occurs the ring buffer file provides the detailed data needed to study the
event.
A ring buffer is active when logging of raw observations for it has started.
One ring buffer can be active at one time. Before starting another ring buffer the active ring
buffer must be stopped.
