NI-IMAQ I/O Test Panel

Use the NI-IMAQ I/O Test Panel to monitor the current values of all NI-IMAQ I/O lines, the isolated port, quadrature encoder, and isolated power status. The digital outputs on your NI-IMAQ I/O device can also be controlled using the NI-IMAQ I/O Test Panel.

FAQs

Q: Why is my digital output line not responding when I change the value of the line using the NI-IMAQ I/O Test Panel?

The digital output line could not be responding if one of the following conditions is present:

• The output line is not enabled. Launch the NI-IMAQ I/O Test Panel (Tools»NI-IMAQ I/O Test Panel and Monitor) to verify that the output line is enabled.
• The output line is currently being used for pulse generation. Verify that the digital output line is not also being used by an Generate Pulse (NI-IMAQ I/O) step in the inspection.
• The output value for the digital output line is being overwritten by another step in the inspection. Verify that the digital output line is not being used by any other Read/Write I/O (NI-IMAQ I/O) or Generate Pulse (NI-IMAQ I/O) step in the inspection.
