Command format in ASCII and NMEA 0183:
aXU,A=x,M=x,C=x,I=x,B=x,D=x,P=x,S=x,L=x
Command format in SDI-12:
aXXU,A=x,M=x,C=x,I=x,B=x,D=x,P=x,S=x,L=x!
where
A, M, C, I,
B, D, P, S,L
= The communication setting fields, see Setting Fields

NOTE When changing the serial interface and communication protocol, note
the following:
Each serial interface requires its specific wiring and/or jumper settings
described in
Chapter 5, Wiring and Power Management, on page 35 .
Change first the serial interface field C and then the communication
protocol field M.
Changing the serial interface to SDI-12 (C=1) will automatically
change the baud settings to 1200, 7, E, 1 and the communication
protocol to SDI-12 (M=S).
NOTE Reset the transmitter to validate the changes of communication
parameters by disconnecting the service cable or using the Reset
(aXZ) command, see
