Additional commands for Quadrature output units
Command
Description
Command Syntax
(command underlined)
ACCUBUBBLE response
(underlined)
"a" represents the single-
character address
XOM Set operating
mode
aXOMm!
Where m is the desired operating
mode. Values for m:
0
Bubbler Operation disabled
.
Quadrature output disabled.
(Low power consumption for
Accububbles being used as a
pressure sensor.)
64 Bubbler operation enabled.
72 Bubbler
with
quadrature
output. Quadrature output will
only be updated when an SDI-
12 measurement is requested.
Default mode for a quadrature
unit.
88
Bubbler with quadrature
output. SDI-12 measurements
not required for the quadrature
output to be updated.
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.
XQC Set Quadrature
Output’s Current
Value
aXQCv!
where v is the value currently
indicated by the quadrature input
device
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 XQC command will return the
specified value.
XQS Set
Quadrature
Scale factors
aXQSstr!
where s is the number of steps to
be output per a full unit of
pressure change as set by the units
of pressure (XUP command)
t is error threshold which must be
exceeded before the unit will start
stepping.
r is the step rate expressed in steps
per second. (optional)
All input values are standard
SDI-12 values with polarity sign.
a0013
indicating the command will be
complete in one (1) second and that
three (3) values can be collected.
NOTE:
A D0 command issued after
the XQS will return three (3) values
representing the quadrature scale
parameters the user has selected. The
rate will be expressed as number of
2
µ
S time ticks between each step. Use
the M5 command to see the value in
terms of a rate.
