Computer Interface C-3
Select firmware commands are divided into the categories described in
Table C-1 below.
Table C-1
Electrostatic Classifier Firmware Commands Description
Used to execute a specific function (such as start and stop a
scan).
Used to read parameters from the instrument (such as flow rate,
pressure, temperature, etc.).
Used to write information to the instrument (such as data, set
points, or settings).
Use prior to most commands to get more information about a
specific command.
Note: When the instrument does not understand a command, it replies
with the string "ERROR".
To use the firmware commands, a program capable of sending and
receiving ASCII text commands can be used. A terminal program such as
HyperTerm (supplied with Windows
®
operating system) is appropriate.
Table C-2 is a quick reference of select firmware commands. The
commands are case insensitive.
Table C-2
Electrostatic Classifier Firmware Commands List (select)
Starts a SMPS spectrometer scan.
Stops a SMPS spectrometer scan.
Shuts down the instrument.
Saves DMA parameters to EEPROM on bottom of DMA, if 3082-
compatible DMA is installed.
Reads the Electrostatic Classifier serial number.
Example: RDSN returns formatted text of 1-19 characters, such as
30821311001
Reads the Electrostatic Classifier model number.
Example: RDMN returns formatted text of 1-19 characters such as 3082
Reads the build string.
Example: RDBS returns a decimal string such as 1.4
Reads the current time.
Example: RDTIME returns formatted text (hh:mm:ss) such as 09:09:23
RDDATE returns the current date.
Example: RDDATE returns formatted text (mm/dd/yyyy) such as
06/01/2012
Read Ethernet
Mac address
RDMAC returns the Ethernet Macintosh address.
Example: RDMAC returns a hexadecimal string such as 10.1.12.221
Read High
Voltage Polarity
RSHVPOL returns the high-voltage polarity setpoint.
Example: RSHVPOL returns 0 or 1, where 0 = negative voltage and 1 =
positive voltage.
RSSHFLOW returns the sheath flow setpoint.
Example: RSSHFLOW returns values in the range 0.0 – 30.0 L/min.
