Appendix III: Command Summary
CATEGORY COMMAND DESCRIPTION
Status
DS
Display status and setup parameters.
Setup
Baud=x
x= baud rate (1200, 2400, 4800, 9600, 19200,
or 38400). Default 9600.
OutputFormat=x
x=0: output raw data in Hex.
x=1: output converted data in Hex.
x=2: output raw data in decimal.
x=3: output converted data in decimal. Default.
OutputSal=x
x=Y: Calculate and output salinity (psu). Only
applies if OutputFormat=3. Default.
x=N: Do not calculate and output salinity.
OutputSV=x
x=Y: Calculate and output sound velocity (m/sec).
Only applies if OutputFormat=3. Default.
x=N: Do not calculate and output sound velocity.
SetDefaults
Reset to default values: OutputFormat=3,
OutputSal=Y, OutputSV=Y, NAvg=1,
MinCondFreq=3000, PumpDelay=30,
ProcessRealTime=Y, TAdvance=0.0625, Alpha=0.03,
Tau=7.0, AutoRun=N.
Autonomous
Sampling
NAvg=x
x= number of samples to average. FastCAT samples
at 16 Hz and averages NAvg samples. Default =1.
MinCondFreq=x
x= minimum conductivity frequency (Hz) to enable
pump turn-on. Pump stops when frequency drops
below x. Default 3000 Hz; factory set to
(0 conductivity frequency + 500 Hz).
PumpDelay=x
x= time (seconds) to wait after minimum
conductivity frequency is reached before turning
pump on. Default 30 seconds.
ProcessRealTime=x
x=Y: Apply alignment, filtering, and conductivity
cell thermal mass corrections to data. Only applies if
OutputFormat=1 or 3. Default.
x=N: Do not apply corrections to data.
TAdvance=x
x= Time to advance temperature data relative
to conductivity and pressure data. Range 0 to
0.125 seconds; default 0.0625 seconds. Only applies
if ProcessRealTime=Y and OutputFormat=1 or 3.
Alpha=x
x= Conductivity cell thermal mass alpha correction.
Range 0.02 to 0.05; default 0.03. Only applies if
ProcessRealTime=Y and OutputFormat=1 or 3.
Tau=x
x= Conductivity cell thermal mass tau correction.
Range 5.0 to 10.0; default 7.0. Only applies if
ProcessRealTime=Y and OutputFormat=1 or 3.
AutoRun=x
x=N: Wait for command when power applied.
Default.
x=Y: Start autonomous sampling when
power applied.
Start
Start autonomous sampling now.
Stop
Stop autonomous sampling. Press Enter key to get S>
prompt before entering Stop.
Polled
Sampling
PumpOn
Turn pump on.
PumpOff
Turn pump off.
TS
Take 1 sample and output data.
Testing
Takes and
outputs
100 samples for
each test. Press
Esc key or Stop
on Toolbar to
stop test.
TT
Measure temperature, transmit converted data.
TC
Measure conductivity, transmit converted data.
TP
Measure pressure, transmit converted data.
TTR
Measure temperature, transmit raw data
TCR
Measure conductivity, transmit raw data.
TPR
Measure pressure, transmit raw data.
