SONTEK Output Data Format<br />
Standard (Single Averaged-Cell) Data: To request and retrieve a standard (i.e., single averagedcell)<br />
sample in SDI-12 SONTEK mode, issue these commands:<br />
Command Response Description _<br />
“aM!” or “aM0!” Initiate measurement request<br />
“aD0!” a±T.TT±P.PPP±L.LLL±CC.C Retrieve 1 st and 2 nd buffers of standard (single<br />
“aD1!” a±X.XX±Y.YY±Z.ZZ±S. averaged-cell) data<br />

Where: (See below for data format description legend.)<br />
Profiling Cell Data: To request and retrieve profiling cell sample data in SDI-12 SONTEK mode,<br />
issue the following commands. Profiling cell data are only available in systems that have the<br />
optional Profiling Mode feature installed.<br />
Command Response Description _<br />
“aM!” or “aM0!” Initiate measurement request<br />
“aD0!” a±T.TT±P.PPP±L.LLL±CC.C Retrieve 1 st and 2 nd buffers of standard (single<br />
“aD1!” a±X.XX±Y.YY±Z.ZZ±S. averaged-cell) data<br />
“aMn!” Request profiling cell (n = cell number 1-5) ††<br />
“aD0!” a±x.xx±y.yy±z.zz±s. Retrieve data for profiling cell n<br />
††<br />
Note: When issuing the “aMn!” command, the data that is sent will be the data that was stored<br />
in the buffer when the “aM!” command was issued. That is, subsequently issuing the same<br />
“aMn!” command will not display new data unless another “aM!” command is issued before<br />
issuing the “aMn!” command.<br />
Where:<br />
Data Format<br />
Standard (Single-Averaged) Cell:<br />
Metric English<br />
T.TT = Mean Temperature °C °F<br />
P.PPP = Mean Pressure decibar psi<br />
L.LLL = Level cm ft<br />
CC.C = Cell End m ft<br />
X.XX = Velocity component 1* (beam 1/X/East) cm/s ft/s<br />
Y.YY = Velocity component 2* (beam 2/Y/North) cm/s ft/s<br />
Z.ZZ = Velocity component 3* (beam 3/Z/Up) [<strong>XR</strong> only] cm/s ft/s<br />
or Velocity Magnitude [SL only] cm/s ft/s<br />
S. = Mean Signal Strength counts counts<br />
Individual Profiling Cell (must have Profiling Mode option installed):<br />
x.xx = Velocity component 1 † (beam 1/X/East) cm/s ft/s<br />
y.yy = Velocity component 2 † (beam 2/Y/North) cm/s ft/s<br />
z.zz = Velocity component 3 † (beam 3/Z/Up) [<strong>XR</strong> only] cm/s ft/s<br />
or Velocity Magnitude † [SL only] cm/s ft/s<br />
s. = Mean Signal Strength † counts counts<br />
Notes: * Cell parameters determined by CellBegin (CB) and CellEnd (CE).<br />
†<br />
Cell parameters determined by CellSize (CS), BlankDistance (BD), and the cell<br />
number (1 through 5) selected in the “aMn!” command.<br />
