4.3 SOFTWARE COMMANDS
Software commands sent via serial communication may be
used to set operational parameters. The sensor must be
configured for serial communication and connected to a PC
or other compatible device using a program like HyperTerm.
New settings are stored in temporary memory and
must be burned to flash with command CMD420 to be
retained.
Note that the P 1 jumper must be configured for
SOFTWARE format to alter baud rate, sample average
count, and output rate parameters.
Although the sensor may receive commands at any
time, measurement output may be paused by sending
three ESC (ASCII 27) characters or CMD300 1. While
paused, COMMAND mode is indicated by a “>” prompt.
All commands must be terminated with a carriage return
CR (ASCII 13).
Use “?” to list available commands as shown below.

CMD100 n OUTPUT PERIOD (0-60 sec)
CMD105 n AVG SAMPLE COUNT (0-32)
CMD110 n OUTPUT FORMAT
(1=ASCII 2=POLLED 3=NMEA 4=RAW 5=DIAG)
CMD120 n MULTIPLIER (10000 = 1.0000)
CMD125 n OFFSET (hPA x 100)
CMD130 n SEA LEVEL CORRECTION (hPA x 100)
CMD140 n VOUT RANGE HI (500-1100)
CMD142 n VOUT RANGE LO (500-1100)
CMD144 n VOUT SCALE (2=2.5V 5=5V)
CMD150 c POLL ADDR CHAR
CMD160 n BAUD RATE (38400,9600,4800,2400,1200)
CMD300 n 1=STOP, 2=RUN
CMD310 n FORCE VOUT (0-5000 FULL SCALE)
CMD400 n 1=RPT TEXT, 2=RPT CODE ONLY

CMD100 n sets output period in seconds. When set to zero,
the output rate is about 1.8 per second.
CMD105 n sets the average sample count. Higher sample
count yields more stable readings but will lengthen
the startup delay.
CMD110 n sets output format. RAW and DIAG settings are
for factory use only.
CMD120 n sets the output multiplier. 10000 represents
1.0000
CMD125 n sets the output offset in hPa x 100
CMD130 n sets the sea level correction in hPa x 100
=[Punadjust *( Mult / 10000)] + [(Offset /100) + (Correction Sea Lvl / 100)]
CMD140 n sets the Vout Pressure Range HI
CMD142 n sets the Vout Pressure Range LO
Vout Pressure Range HI must be greater than Vout
Pressure Range LO
CMD144 n sets the Vout Scale. 2 = 0 to 2500 mV. 5 = 0
to 5000 mV. This parameter setting must agree with
the physical P3 jumper position to achieve calibrated
voltage output.
CMD150 c sets the poll address character. Any ASCII
character from ‘0’ (ASCII 48) to ‘z’ (ASCII 122) may
be used.
CMD160 n sets the baud rate. Acceptable values are
38400, 9600, 4800, 2400, and 1200. Note that the
baud rate change occurs immediately after the
command is received. Therefore, in order to continue
communicating, the serial communication program
that issued the command must also change to match.
CMD300 n causes the sensor to pause or resume
measurement. 1 = Stop, 2 = Run.
CMD400 n causes the sensor to issue a report
summarizing parameter settings.
1 = RPT text
2 = RPT code only
CMD410 retrieves the internal calibration table. This is for
factory use only.
CMD420 burns new parameter settings to flash memory.
This step must take place to retain changes otherwise
parameters will revert to the previous values at the
next powerup.
