Virtual Instrument Operation
RS-232 Virtual Instrument
Open the Model 18X via Serial Port.vi. Before running the VI, the user
must select an initialization option and provide any necessary settings. In
order to initialize the VI, scroll to the area above the virtual front panel.
Several controls are visible for setup by the user. The figure below
illustrates the available controls. The Initialize State from Instrument?
switch allows the user to select whether the instrument is initialized from
the current settings of the actual instrument or from the controls available
from the VI. If the Yes option is selected, the VI will initialize all settings
from the actual instrument. If the No option is selected, the user should
enter all data in the control fields (Sensor Length, Hi Setpoint, etc.) in the
indicated units. The user should also select the correct RS-232 port and
baud rate, according to the port to which the Model 185/186 is connected
and the baud rate to which the instrument is set (see page 36 for
instructions on setting the Model 185/186 baud rate). The user may then
start the VI. Please refer to your LabVIEW documentation for instructions
on how to start and control the execution of VI’s.
Set 186 Fill via Serial Port.vi Configures the fill interval setting.
Set 18X HI via Serial Port.vi Configures the HI setpoint.
Set 18X Length via Serial
Port.vi
Configures the active sensor length.
Set 18X LO via Serial Port.vi Configures the LO setpoint.
