options which you can add to your BWS200 are outlined below. Note that all will
require additional software running in both the logger and the PC.
5.2.1 Short Haul Modem
Campbell Scientific is able to provide a Short Haul point to point communications
package with modems for either end of a fixed line cable to be supplied by the
customer. Distances up to 25km are possible via this method. This popular option
can be bought as a complete package and installed by the user.
5.2.2 Multidrop Communications
As the name implies Multidrop communications allows a number of weather
stations to sit on the same data bus. For example a number of weather stations
located around a farm might all be connected together in a ring, star or line
formation onto the same cable. Campbell Scientific’s MD485 interfaces will direct
the communications to the appropriate station.
5.2.3 Radio Communications
Short range radio communications are also possible but would require and
alternative logger and so must be specified before ordering or will require your
unit to be returned for upgrade.
Note that all of the above options will require additional software either in the
logger and/or in the PC. The cordless methods in particular will also have a major
impact on the power budget of the unit and steps will need to be taken to minimise
power loss. Please contact Campbell Scientific for more details and advice.
The following communications connections require either PC400 or LoggerNet software:
5.2.4 PSTN Telephone Connection
Where your weather station has access to a fixed line telephone connection you
can add a COM200E telephone modem and dial the logger up from your PC.
5.2.5 GSM/GPRS Modem
To connect via the GSM mobile network you will need a CS-GSM/GPRS kit
including a GSM modem, antenna and connection leads. A Data SIM card should
be obtained from your local authorised reseller. Refer to the manual.
5.2.6 Internet Access
To access your data via an Ethernet connection kit you will need a configured
NL201 network module.
