Troubleshooting Genie Monochrome Series-GigE Vision Camera
With a computer that is not behind a corporate firewall an alternative is to disable Windows firewall only for the
network adapter dedicated for the Genie camera. Such a computer would have two or more network adapters where
one NIC only connects to the Genie—never the Internet.
The following figures show an example of the Windows firewall On but disabled for the network adapter used by
Genie.
Windows Firewall Off for Genie Only
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
48 ).
