11.6 METAR Codes produced by the CS125
The following METAR codes from WMO table 4678 can be output by the CS125.
UP Unidentified precipitation
HZ Haze
BR Mist
FG Fog
DZ Drizzle
RA Rain
SN Snow
SG Snow grains
PL Ice pellets
Notes:
HZ will only be reported if a CS215 is connected to allow relative humidity
information to be available.
FZ (freezing) may be added as a descriptor in front of BR, FG, DZ and RZ
Intensity qualifiers, ‘-‘ for light, ‘+’ for heavy, may be added in front of DZ, RA,
SN, SG and PL
Combinations, for example RASN for rain and snow can be reported.
12. Interface methods
– Device Configuration
Utility/Command line/Menu
The CS125 can be setup and controlled in one of three ways.
The first method is by using Campbell Scientific’s Device Configuration Utility
Software (DevConfig) which is included with each delivery on the manuals/
resource disk. This software allows an easy menu driven interface for configuring
the CS125 on any Microsoft™ based personal computer. All settings can be
accessed using this program.
The program includes online help instructions that describe its general use with
the CS125 and also how to load an operating system.
The Device Configurator can also be used as a terminal emulator to use the built-
in menu system of the CS125 and to access its calibration menu.
The second method is by using the command line interface where discrete
commands are sent without response from the sensor. This would be the preferred
method of setting up a CS125 if it was connected to a logger for instance. The
configuration setting commands can be sent via a logger to the CS125 removing
the need for a local PC to set up the unit.
The third method is by using the simple menu interface built into the CS125
communicating via RS232 or RS485, using a terminal emulator program. This
menu system gives access to the more common settings.
All three of these methods use the CS125s serial port A to communicate with the
sensor. Configuration cable part number 010817, described in section 8.1 can be
used.
