Initial Settings
FS11P Present Weather Sensor is typically interfaced to a host computer
or a data logger in an automatic weather observation system. After the
physical connection has been made, the details of the communication can
be configured into the FS11P software. Suitable communication settings
depend on the implementation of the entire system.
By default the sensor transmits a new ASCII data message through the
data port in RS-232 mode every 15 seconds. The user can change the
interval and message type. The sensor can also be used in a polled mode,
in which a data message is only sent when the host computer requests
one with a special command. The default communication settings are
listed in Table 8 below.

In multipoint communication, where several sensors share the same
communication line (RS-485/Modem), the FS11P sensor should be used
in the polled mode and the individual sensors should have distinct
identifiers (ID).
