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.
