Gps Test; Set Default Baudrate; Engineering Units - RBR 1050 Series User Manual

GPS test

Confirmation that a GPS unit is properly connected, configured and working can
be obtained by running a GPS test from the Logger Functions menu. If the
GPS unit has been connected and configured properly, a small dialog box will
display the current latitude and longitude. Please ensure that the COM port to
which the GPS unit is connected has been specified in COM settings (p.32).

Set default baudrate

Generally, loggers are shipped to operate at a
default baudrate of 19200 baud. This is the
communication rate that the logger uses when it
wakes or new batteries are inserted. Users
may wish to employ a different rate and this
window allows the user to select one of a set of
possible baud rates.

Engineering units

RBR loggers communicate readings to the outside world on the logger serial line
as a response to the command Fetch live readings and in the real-time mode.
The traditional and most compact mode is the binary mode where readings are
transmitted as their raw 24-bit values. However, this mode cannot be viewed on
a serial terminal device such as that provided by the Hyperterminal program
available in Windows. Hence, RBR loggers can be switched into a mode which
transmits the information in printable ASCII characters in an engineering units
format. In real-time operation, the readings from the logger in the engineering
units format will appear with a timestamp header followed by the channels in
order and terminated with the characters "FET". An example is shown below for
a temperature and pressure logger, the start time is 2004/9/11 21:45:00 with
samples being taken every 5 minutes. The data following the timestamps are
temperature and pressure.
Once set into the binary or engineering units modes, a logger will persist in this
mode. The Engineering units menu item is provided to allow a user to change
the mode. A visual cue is provided on the status bar of the RBR Windows
Software to confirm the current
setting of a logger. The "1.234"
logo indicates engineering units
and the "10101" logo, binary.
