Page 88: Unexpected Events
Troubleshooting and performance Unexpected events How do I get the camera back to normal operation? Check if an error is displayed by the camera Status LED. The status LED signals 4 short flashes followed by another sequence. Then: Restart the camera. If the camera still does not respond. -
Page 89: Performance
Troubleshooting and performance Performance How can I improve camera performance? Check if the hardware sufficiently supports your USB camera. See the Alvium USB Cameras Accessory Guide at https://www.alliedvision.com/en/support/technical-documentation/ alvium-documentation.html. Check if the camera shares the bus with other devices reducing the available bandwidth. -
Page 90: Radio Signal Interference
Troubleshooting and performance Radio signal interference How can I avoid radio signal interference from wireless devices? Ensure camera installation complies with Electromagnetic Compatibility. Wireless devices and USB 3.0 / 3.1 Gen 1 commonly use 2.4 GHz frequency (WLAN uses 2.4, 3.6, and 4.9 GHz). Even USB 3.0 / 3.1 Gen 1 cables can interfere harmfully with other electromagnetic devices. -

Troubleshooting and performance Optimizing performance Operating systems and bandwidth Even if your hardware supports high bandwidths, you may encounter corrupted frames. This is some best practice advice. Windows and Linux For smooth data transfer of USB3 Vision cameras, the host computer must be equipped with a high-performance USB controller. - Page 92 Troubleshooting and performance Linux only Adapting the Vimba USB Transport Layer settings To ensure compatibility with older Linux versions, the default value of in the Vimba USBTL (USB Transport Layer) is not very high. MaxTransferSize To optimize the performance, adjust the value of the VimbaUSBTL.xml file: 1.

Page 95: Cascading Hubs Divide Bandwidth
Troubleshooting and performance Cascading hubs divide bandwidth The following example applies to standard behavior without individual settings. The graphics show bandwidth distribution on a common bus. Three cameras try to use full bandwidth at the same time. If one camera is inactive, the host will provide its share to the others until this camera sends data again. - Page 96 Index Index image data flow ..........83 intended use ........... 16 interfaces ............71 IR cut filter ............54 AcquisitionActive ..........79 Allied Vision contact ..........3 codes ............76 bandwidth error conditions ........76 cascading hubs ..........95 lens mounts ............. 53 division on a common bus ......94 lenses ..............
