|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.  Davis stations calculate Sea Level Pressure from Station Pressure using a formula based on several parameters such as temperature, humidity, etc, rather than just using altitude as most other stations. CWOP require 'Altimeter Pressure' to be uploaded, i.e. a value calculated simply using altitude.

The following note applies to Cumulus 1.x.x; for MX, use of the LOOP2 (see [[Cumulus.ini_(Beta)#Section:_Station| here]]) means s.l.p. can be obtained from the Davis station.  
'''Note for MX''', use of the LOOP2 (see [[Cumulus.ini_(Beta)#Section:_Station| here]]) means s.l.p. can be obtained from the Davis station.
The station does not provide this value directly, nor the station pressure, so Cumulus 1.x.x has to read some extra data once a minute in order to do the calculation. This can take several seconds, so it means that a 'normal' data reading may be missed.

If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0.
