(underlined)
"a" represents the single-
character address
XAR Set Analog
Output range
aXARzf!
where z is the pressure in mB or
hPa to be represented by
0.000 VDC
f is pressure in mB or hPa to be
represented by 5.000 VDC
All input values are standard SDI-
12 values with polarity sign.
a0012
indicating the command will be
complete in one (1) second and that
two (2) values can be collected.
NOTE:
A D0 command issued after
the XAR will return two (2) values
representing the pressure range that the
user has selected.
Note Version 2.0 and higher:
Current settings can be queried by
issuing the aXAR! Command followed
by the aD0! Command.
XAO Set Analog
Output to a fixed
voltage
aXAOv!
where v is the required output in
VDC
All input values are standard
SDI-12 values with polarity sign
a0011
indicating that the command will take
one (1) second to complete and that
one (1) value can be collected
NOTE:
A D0 command issued after
the XAO command will return the D/A
value corresponding to the requested
voltage.
The unit's output will not act as a
pressure sensor again until this same
command is given with a negative
voltage request.
XOM Set operating
mode
aXOMm!
where m is the desired operating
mode.
values for m
0 Background operation
disabled. (Low quiescent
power consumption for analog
units being used as a digital
only unit.)
16 Continuously update analog
output.
All input values are standard
SDI-12 values with polarity sign
attt1
Indicating that the command will take
ttt seconds to complete and that one (1)
value can be collected
NOTE:
A D0 command issued after
the XOM command will return the set
operating mode.
Note Version 2.0 and higher:
Current settings can be queried by
issuing the aXOM! Command followed
by the aD0! Command.
