Compliance, safety, and intended use
Ground loops
Unsuitable connections can lead to different potentials between the camera
system GND and the environmental shield/chassis GND caused by ground loops.
This can damage the camera and the connected devices or cause malfunctions.
• Avoid potential differences between the camera housing and GND.
• All wiring must be done by authorized personnel, according to the
corresponding technical standards.
• Read the Avoiding Ground Loops in Vision Systems application note.
USB connections
USB 3.0 and 3.1 Gen 1 host controllers and hubs
To avoid damage to USB 3.0 or 3.1 Gen 1 host controller cards or hubs, make sure
these components provide sufficient current supply for the connected cameras.
For suitable USB 3.0 accessories, see the Alvium Cameras Accessory Guide at
www.alliedvision.com/en/support/technical-documentation/
If suddenly your camera is not recognized anymore, check for a crashed USB hub.
Disconnect the USB and power supply cable from the hub. Reconnect both.
USB cables
Proper cable handling enables reliable performance:
• Use only shielded cables to avoid electromagnetic interferences.
• Please use cables recommended by Allied Vision.
• Avoid unnecessary bending to prevent damage to the cables.
