Title
Description
WSCONTROL
Write Control of
Classifier
WSCONTROL sets who has control with AIM, OPEN, or GUI.
Example: WSCONTROL OPEN sets to classifier control
WSGPIODIGOUT0
Write GPIO
Digital Output 0
WSGPIODIGOUT0 sets the GPIO output to 0 or 1.
Example: WSGPIODIGOUT0 1 turns the output on, 0 turns the output
off.
WSGPIODIGOUT1
Write GPIO
Digital Output 1
WSGPIODIGOUT1 sets the GPIO output to 0 or 1.
Example: WSGPIODIGOUT1 1 turns the output on, 0 turns the output
off.
WSSCANPARAM
Write SMPS
Scan Parameters
WSSCANPARAM sets the following scan parameters:
tres, time resolution in milliseconds, fixed at 20 ms.
tlow, time DMA voltage held at vmin in milliseconds, 0 to 10000 ms
tup, time DMA voltage is ramped up in milliseconds, 0 to 300000 ms
thigh, time DMA voltage held at vmax in milliseconds, 0 to 10000 ms
tdown, time DMA voltage ramped down in milliseconds, 0 to 300000 ms
vmin, starting DMA voltage, 1.0 to 100000.0 v
vmax, ending DMA voltage, 1.0 to 10000.0 v
pol, polarity of DMA voltage, where -1 = negative voltage, 0 = detectors
with no voltage, 1 = DMA voltage
Example: RSSCANPARAM 20,500,10000,500,1000,13.1,9456.0,-1 will
have a voltage of 13.1 to 9456 over the tup time of 10 seconds
WSPARTICLEDIAM
Write Classifier
Particle Diameter
WSPARTICLEDIAM sets the particle diameter setpoint.
Example: WSPARTICLEDIAM 100 sets the particle diameter to 100.
WSDMAMN
Write DMA
Model Number
WSDMAMN sets DMA model number. Saves to EEPROM on bottom of
3082-compatible DMA. Should be followed by a
DOSAVEDMAEEPROM.
Note that the suffix “A” is not used.
Example: WSDMAMN 3085 sets model number to 3085.
WSDMASN
Write DMA Serial
Number
WSDMASN sets DMA serial number. Saves to EEPROM on bottom of
3082-compatible DMA. Should be followed by a
DOSAVEDMAEEPROM.
Example: WSDMASN 3085114501 sets DMA s/n to 3085114501.
WSDMALENGTH
Write DMA
Length
WSDMALENGTH sets DMA length, in meters. Used by inversion
algorithm. Saves to EEPROM on bottom of 3082-compatible DMA.
Should be followed by a DOSAVEDMAEEPROM.
Example: WSDMALENGTH 0.44369 sets DMA length to 44.369 cm.
WSDMAID
Write DMA Inner
Diameter
WSDMAID sets DMA inner diameter, in meters. Used by inversion
algorithm. Saves to EEPROM on bottom of 3082-compatible DMA.
Should be followed by a DOSAVEDMAEEPROM.
Example: WSDMAID 0.01874 sets DMA inner diameter to 1.874 cm.
WSDMAOD
Write DMA Outer
Diameter
WSDMAOD sets DMA outer diameter, in meters. Used by inversion
algorithm. Saves to EEPROM on bottom of 3082-compatible DMA.
Should be followed by a DOSAVEDMAEEPROM.
Example: WSDMAOD 0.03922 sets DMA outer diameter to 3.922 cm.
WSDMATYPE
Write DMA Type
WSDMATYPE sets the DMA type to 1 (cylindrical) or 2 (radial). Used by
inversion algorithm. Saves to EEPROM on bottom of 3082-compatible
DMA. Should be followed by a DOSAVEDMAEEPROM.
Example: WSDMATYPE 1 sets DMA type to cylindrical.
WSCUSTOMDMALENGTH
Write Custom
DMA Length
WSCUSTOMDMALENGTH sets length of custom DMA, in meters. Used
by inversion algorithm. Should be followed by a DOREGSAVE.
Example: WSCUSTOMDMALENGTH 0.44369 sets custom DMA length
to 44.369 cm.
