Using the TR500 with the RS500
When the RS500 is turned on using
the TR500, the following screen will
appear.
The RS500 has the same main menu
panel as the SR5xx sensors except
that the first three menu options are
removed. It is also not possible to
perform the real-time configuration for
the RS500. This needs to be done
using remote control software. All
data management, job control and
sensor status operations required by
an RS500 user are possible using the
menu options shown above.
The RS500 also has reduced
CONFIG and STATUS options. Only
the options that are relevant to
operating an RS500 are available.
Full details on the CONFIG and
STATUS menu options available are
described in the main body of this
manual. TR500 configuration options
unique to the RS500 sensor are
described in the following sections. Ring Buffer Functionality
The RS500 is supplied as standard
with ring buffer functionality. The ring
buffer allows a second set of GPS
raw data to be recorded at a different
observation rate as is defined within
the standard/primary logging configu-
ration.
The user can define the time period
for storing data into the ring buffer.
For example, if the user chooses to
store 1 hour of data into a ring buffer
then the last one hour of stored data
will always be available. Data that is
older than 1 hour is automatically
over-written by the data currently
being logged. When the logging into
a ring buffer is activated a check will
be made that there is enough free
space on the PC Card or internal
memory to log the data with the
desired logging rate and duration.
