8.1.3.2 Setting Fields
Parameter Description
[R]
Parameter selection: This field consists of 16 bits defining the precipitation parameters
included in the data messages. The bit value 0 disables and the bit value 1 enables the
parameter.
Bits 1-8 determine the parameters included in the messages obtained with the following
commands:
•
ASCII: aR3 and ar3
• NMEA 0183: $--WIQ,XDR*hh
• SDI-12: aM3, aMC3, aC3, aCC3
• SDI-12 continuous: aR3 and ar3

& delimiter
Bits 9-16 determine the precipitation parameters included in the composite data messages
obtained with the follo
wing commands:
• ASCII:
• NMEA 0183: aR0, ar0
• SDI-12: aM, aMC, aC, aCC
• SDI-12 continuous: aR and aRC
