4.4.2 Other Installations
For installations other than those with the SPM2 Mast, you must ensure adequate
grounding facilities. If you are mounting the weather station at a high level (on a
roof etc.) you must run a grounding wire to a good ground point. A full grounding
system, including clamps and ground spikes, can be provided if required. Please
contact Campbell Scientific for price and further details.
5. Installing a Communications Link
There are several ways to communicate with the datalogger in your Basic Weather
Station in order to retrieve data. The most common, and recommended, method is
to use a direct link to a computer, either a laptop on site, or connected to a desktop
PC at any convenient location using an appropriate interface package. As a further
option, communication can be carried out by using a remote communications
package with a modem to transmit data, either via the public telephone network or
by one of the cellular networks.
Please contact Campbell Scientific if you require assistance in selecting an
appropriate interface.
5.1 Communication Directly to the PC
For computer/weather station distances of up to 15 metres the simplest method is
direct connection from the PC Serial Port to the RS232 Port on the CR200X Series
datalogger.
Many customers have successfully used this type of set up for
distances of up to 75 metres, but success will depend on a number of
factors, including cable type and size. Campbell Scientific cannot,
therefore, guarantee effective communication quality at distances
more than 15 metres. A long connection is also more vulnerable to
lightning damage and so you would need to consider extra lightning
protection measures.
For distances over 15 metres consider using a communications link using either
MD485 Multidrop Interfaces or the CR216X radio datalogger. See following page.
5.2 Other Communication Options
If you have ordered your BWS200 with an alternative communications option then
please refer to the manual for that option for further information on setting up the
communication link. If you have bought the basic BWS200 then communication
