Casella CEL Nomad portable weather station - Manual (Page 26)

A GSM system with a suitably short call-up interval can be used, but
may incur high call charges. Such systems are best used to download date once
or twice each day. Note also that if the GSM is set to read data once each hour,
the display will update only once each hour.
A set of eight standard pre-configured real-time display screen pages
are included for Nomad systems and these will be installed by the configuration
file loaded into Online Pro the first time it is started. Figure 8 shows some of the
standard pages.
When required, the standard screen pages can be edited or completely
new page layouts prepared by the user. The data from several measuring
stations can be presented on the same screen page, where the only limitation is
the user’s ingenuity in positioning the required items on the page. Figure 9
shows some of the possibilities. Sections 5.3.2 and 5.3.3 describe how to edit or
add to the screen settings.
The application can switch between real-time pages automatically to
allow the data from all stations to be monitored constantly in a specified
sequence.
