Testing Single-Value Digital Output
To verify that the module can output a single digital output value, do the following:
1. Connect a digital output to digital output line 0 of port B on a DT9816 Series module.
Refer to
page 39 for an example of how to connect a digital output.
2. In the Quick DataAcq application, select Digital Output from the Control menu.
3. Select the appropriate DT9816 Series module from the Board list box.
4. Select digital output port B by clicking Port B .
5. Click the appropriate bits to determine the value to write to the digital output lines. If the
bit is selected, a high-level signal is output from the digital output line; if the bit is not
selected, a low-level signal is output from the digital output line. Optionally, you can
enter an output value in the
Hex text box.
6. Click Send .
The application outputs and displays the value of each digital output line of digital port B on the
screen in both text and graphical form.
