6.3 RS422/RS485 interface
With RS422 data are sent immediately after applying power to the station.
With RS485 the station can receive data after applying power but does not send any data. The
output is tri state. Data only will be sent on request with the correct address.
Initalization and memory check with RS485 are performed as well but without sending any data
for the output is disabled (tri state).
While initializing after power up the weather station doesn't respond to any commands for app.
10 seconds.
For controlling the weather station with RS485 the address of the weather station must be added
after the ! or ? command, otherwise the unit won't respond to any command.
The default address with RS485 is 1.
The command for reading the current data set therefore is ?1U for example contrary to ?U with
all the other interface versions.
