114 • Troubleshooting Genie Monochrome Series-GigE Vision Camera
Camera Exposure Issues
No camera exposure when expected.
• Verify by using the camera in free-running mode. Do not use external trigger mode when testing a camera
setup.
• If using free-running mode, verify that the exposure period is set to the maximum possible for the set frame
rate.
• Load factory default from the Power-up Configuration in CamExpert. This will reset the camera to its
nominal acquisition rate.
Camera is functional but frame rate is lower than expected.
• Verify Ethernet link speed. If the LAN connection is limited to 100 Mbps, the monochrome Genie frame
rate maximum will be around 30 fps for a 640x480 exposure. Higher resolution Genie models would have
even lower frame rates without a Gigabit Ethernet connection.
• If using an external trigger, verify the trigger source rate and Genie parameters such as trigger to exposure
delay.
• Verify the exposure mode type is Synchronous, not Reset mode. (See "
Synchronization Timing" on page
46).
Camera is functional, frame rate is as expected, but image is black.
• Verify that the lens iris is open.
• Aim the Genie at a bright light source.
• Check that the programmed exposure duration is not too short or set it to maximum. See "
Exposure
Controls" on page 43.
• Using CamExpert set the Genie to output its internal pattern generator. This step is typically done for any
camera installation to quickly verify the Genie and its software package.
