NI 17xx Smart Camera User Manual

IMG ACQ LED

The IMG ACQ LED briefly lights green when an image is captured and ready for analysis. Fast
frame rates can give this LED the appearance of being continuously lit.

If the IMG ACQ LED and the FAIL LED both flash red, it indicates that the NI Smart Camera
has shut down because the maximum internal temperature was exceeded. Refer to the

Considerations

section of Chapter 8,

Thermal Considerations and Mounting

, for information

about measuring the temperature of the smart camera. Refer to Appendix A,

Specifications

, for

complete specifications.

PASS LED

The PASS LED is a green LED that is user-configurable through the IMAQ property node in
LabVIEW or the

Read/Write I/O

step in Vision Builder AI.

3 Flashes

Green

The smart camera is in safe mode because the SAFE MODE
DIP switch is in the ON position. Refer to the

Configuring DIP

section for information about the SAFE MODE DIP

switch.

4 Flashes

Green

The smart camera has experienced two consecutive software
exceptions. The smart camera automatically restarts after an
exception. After the second exception, the smart camera
remains in the exception state, alerting you to resolve the
problem. Reinstall software on the smart camera or contact
National Instruments for assistance. Refer to

Getting Started

with the NI 17xx Smart Camera

for information about

installing software on the smart camera.

5 Flashes

Green

The smart camera detects a critical error. Reinstall software on
the smart camera or contact National Instruments for
assistance. Refer to

Getting Started with the NI 17xx Smart

Camera

for information about installing software on the smart

camera.

Flashing

Red

The smart camera detects a software crash or hang.
Contact National Instruments for assistance.

Solid

Red

The smart camera detects a critical firmware error. Contact
National Instruments for assistance.
