Genie Color Series-GigE Vision Camera Troubleshooting • 117
Acquisition Error without Timeout Messages
Streaming video problems range from total loss of image data to occasional loss of random video data packets. The
following section describes conditions identified by DALSA engineering while working with Genie in various
computers and setups.
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
47).
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. See "
Internal Image Test Patterns"
on page 61 for information on using CamExpert to select internal patterns from Genie.
Grab has Random Bad Data or Noise
The problem is seen as random noise and missing sections of video data from the acquisition. All configuration
parameters seem correct and the Ethernet cable is secure. The following image shows an example of this type of bad
acquisition while testing a Genie installation with CamExpert (with the Genie set to generate its internal test
pattern).
