Output Type: The choice of 5 different output formats can be made using the this
parameter.
CSV: Selecting the CSV format option results in the unit sending ASCII data in the
following arrangement:
# CAST 1 Meters Records 3
09/16/99, 11:33:17, 1503.0,1.5,16.0
09/16/99, 11:33:17, 1503.4,2.0,15.0
09/16/99, 11:33:17, 1503.9,2.5,14.0
The CSV cast data begins with the header line showing the # of the Cast (#1 in
the example), followed by the measurement unit (meters in this example), and by
the number of records in the file (in this example only 3 individual samples were
stored). Once the header line is complete, each individual record is listed
beginning with the date, followed by time, velocity, depth, and probe temperature.
SVP16: In this configuration, the Digibar Pro emulates the output string of the SVP
16 sound velocity profiler.
"CALC, DBxxxx, 09/16/99, 1, Meters"
OHSI Sound Velocity Profiler S/N DBxxxx
Date: 99259 Time: 1133
Depth Offset (M): 0

NMEA: This output string complies with the sentence structure of the NMEA
standard for manufacturer's proprietary strings.
$PSSV, 1503.0, 1.5,M*54 (for Units = Meters)
$PSSV, 4860.0, 4.0,F*52 (for Units = feet)
The "$" character denotes start of sentence.
"P" Proprietary sentence ID
"SSV" Manufacturer's mnemonic code
"," The comma delimiter character starts each field except address and checksum
<ccc> Velocity, Depth, Measurement units data fields
"*" Checksum delimiter
<Checksum field> The absolute value calculated by exclusive-OR'ing the 8 data
bits of each character in the sentence between, but not including the "$" and "*".
<CR><LF> End of sentence
