Subsystems and Analog I/O
The following sections describe how DriverLINX implements Digital
Input Subsystem features and Analog Output Subsystem features for the
DDA-08/16. Refer to
DriverLINX Installation and Configuration Guide
and
Using DriverLINX with Your Hardware, Keithley DDA-08/16
manuals for more information.
Digital Input Subsystem
Digital Input Operations
The DDA-08/16 supports two types of operation:
●
Initialize
—
Aborts any active interrupt data-acquisition tasks and
stops the clock. However, DriverLINX prevents one application from
interfering with another application’s data-acquisition tasks.
●
Message
—
DriverLINX displays a pop-up dialog box for the user
containing the text for the current DriverLINX error message.
Digital Input Timing Events
Timing Events specify how the hardware paces or clocks the reading of
Digital Input samples. Because the DDA-08/16 does not have any digital
input data channels, DriverLINX does not allow an application to create
any independent tasks with the Digital Input Subsystem. Refer to
DriverLINX Installation and Configuration Guide
and
Using DriverLINX
with Your Hardware, Keithley DDA-08/16
manuals for more information.
