300 • Troubleshooting Nano Series GigE Vision Camera
•
In multiple NIC systems where the NIC for the Nano is using LLA mode, ensure that no
other NIC is in or switches to LLA mode. It is preferable that the Teledyne DALSA DHCP
server is enabled on the NIC used with the Nano instead of using LLA mode, which prevents
errors associated with multiple NIC ports.
•
Verify that your NIC is running the latest driver available from the manufacturer.
Device IP Error
The GigE server tray icon shows a warning with IP errors. Review the following topics on network
IP problems to identify and correct the condition.
Please refer to the Teledyne DALSA Network Imaging Package manual for information on the
Teledyne DALSA Network Configuration tool and network optimization foe GigE Vision cameras and
devices.
Multiple Camera Issues
• When using multiple cameras with a computer with multiple NIC ports, confirm each Nano
has been assigned an IP address by checking the GigE server.
•
To reduce network traffic in configured problem free systems, use the Network
Configuration tool to stop camera discovery broadcasts. Refer to the Teledyne DALSA
Network Imaging manual.
• When using multiple cameras connected to an VLAN Ethernet switch, confirm that all
cameras are on the same subnet setup on that switch. See the Teledyne DALSA Network
Imaging package manual for more information. .
•
If a Nano camera installed with other GigE Vision cameras cannot connect properly with the
NIC or has acquisition timeout errors, there may be a conflict with the third party camera’s
filter driver. In some cases third party filter drivers modify the NIC properties such that the
Teledyne DALSA Sapera Network Imaging Driver does not install. Verify such a case by
uninstalling the third party driver and installing the Nano package again.
• Verify that your NIC is running the latest driver available from the manufacturer.
Device Available but with Operational Issues
A properly installed Nano with no network issues may still not perform optimally. Operational
issues concerning cabling, Ethernet switches, multiple cameras and camera exposure are discussed
in the following sections:
Always Important
• Why should Nano firmware be updated? See Firmware Updates.
•
Power Failure during a Firmware Update–Now What?
•
Cabling and Communication Issues
•
See Preventing Operational Faults due to ESD to avoid random packet loss, random camera
resets, and random loss of Ethernet connections.
No Timeout messages
•
I can use CamExpert to grab but the image is corrupted with bad data. See Grab has
Random Bad Data or Noise.
•
I can use CamExpert to grab (with no error message) but there is no image (display window
stays black). See Acquisition Error without Timeout Messages.
•
I can use CamExpert to grab (with no error message) but the frame rate is lower than
expected. See Camera acquisition is good but frame rate is lower than expected.
