Command Descriptions
This section describes commands and provides sample outputs. See
Appendix IV: RS-232 Command Summary for a summarized command list.
When entering commands:
• Input commands to the SBE 38 in upper or lower case letters and register
commands by pressing the Enter key.
• The SBE 38 sends ? CMD if an invalid command is entered.
• If the system does not return an S> prompt after executing a command,
press the Enter key to get the S> prompt.
Status Command
DS
Display status and setup parameters.
Equivalent to Status on Toolbar.
Description in example includes, where applicable,
command used to modify parameter.
Setup Commands
Interface=x x=232
: Set interface to RS-232.
x=485 : Set interface to RS-485. See Appendix III:
RS-485 Interface for all details.
Baud=x x=
baud rate (1200, 2400, 4800, 9600).
Default 9600.
Format=x x=C
: Output converted data (°C).
x=R
: Output raw data (counts).
Digits=x x= number of digits (0 – 6) to right of decimal point
for converted temperature (°C). Applicable only if
Format=C .
NAvg=x x= number of A/D cycles to average per sample
(1 – 127).
Time between samples (seconds)
= (0.133 * NAvg ) + 0.339
(Time between samples for continuous sampling;
minimum time required for each polled sample.)
AutoRun=x x=N : Wait for a command when power is applied.
x=Y : Start continuous sampling automatically when
power is applied.
Example: (user input in bold).
S>
DS
SBE 38 V 1.4 S/N = 0090 (firmware version, serial number)
NAVG=1
(number of A/D cycles to average for each sample [
NAvg=
])
Not sampling data (sampling status)
Automatically start sampling on power up (sampling start-up mode [ AutoRun= ])
Default interface is RS-232 (RS-232 or RS-485 interface [ Interface= ])
Note:
If the voltage is below 6.5 volts, the
following displays in response to DS :
WARNING: LOW BATTERY VOLTAGE!!
Note:
The SBE 38’s baud (set with Baud= )
must be the same as SEATERM’s
baud rate (set in Configure menu).
Note:
After you send AutoRun=Y , to start
sampling immediately:
• Turn power off and then on again, or
• Send Go .
Notes:
• The SBE 38 transmits data after it
has completed the previous sample
and before it starts the next sample.
• For continuous sampling with an
RS-485 interface, set NAvg > 30.
See Appendix III: RS-485 Interface .
