Commands
When using SeaCast, the full command set is not usually necessary. However, text commands are available.
Below is a listing of commonly used commands. Note that some commands are only available on instruments
equipped with the appropriate
Xchange™
sensors.
Communications Commands
Command
Description
Requires
SET FORCE 232
Sets com mode to RS-232. Power must be cycled for
changes to take effect.
SET FORCE 485
Sets com mode to RS-485. Power must be cycled for
changes to take effect.
SET FORCE AUTO
Sets for auto-detection of RS-232 or RS-485 comms. Note
that if instrument is not connected to a com port on power
up, it assumes RS-485 operation and will remain in that
mode until powered down.
DISPLAY FORCE
Displays current com mode (ie RS232, RS485, AUTO)
DISPLAY DETECT
Displays the baud rate detection settings.
SET DETECT a b
Sets the baud rate detection. “a” sets the number of
autobaud detection attempts before the instrument reverts to
the default baud rate set by “b.” Setting ‘a’=0 forces the
instrument to a fixed baud rate determined by “b.”
”b”=
1 = 600
baud
4 = 4800
baud
7 = 38400
baud
2 = 1200
baud
5 = 9600
baud
8 = 57600

3 = 2400
baud
6 = 19200
baud
9 = 115200
baud
Sampling Rate Commands
Command
Description
Requires
DISPLAY SAMPLE
RATE
Displays the time-based sampling rate.
SET SAMPLE n t
Sets the desired sampling rate. “n” is a number and “t” is the
time units. Using the slash ( / ) character should be read as
"per". For instance, 5 s means sampling happens every 5
seconds. 5/s means 5 samples per second. Examples are:
SET S C
sets the sampling to continuous (25 Hz)
SET S 5 /s
5 samples per sec
SET S 1 s
Sample 1 time every 1 second
SET S 2 /m
2 samples per minute
SET S 5 m
Sample 1 time every 5 minutes
SET S 2 /h
2 samples per hour
SET S 24 h
Sample 1 time every 24 hours
DISPLAY INCREMENT
Displays logging increment for pressure in dbar.
P

SET PRESSURE
INCREMENT n
Sets logging by increment of pressure specified by n =
increment value in dBar (resolution of 2 decimal places).
P
•X
SET SOUND
INCREMENT n
Sets logging by increment of SV specified by n = increment
value in m/s (resolution of 1 decimal place).
SV

DISPLAY SOUND
INCREMENT
Displays the logging increment for sound velocity in m/s.
