USB 2.0 cabling and connection

uEye Camera Manual Version 4.00

USB 2.0 cabling and connection

In order to comply with the specifications, the maximum length of USB 2.0 cables is limited to 5 m. Longer cables may be connected if you use high-quality material. For cameras of the USB uEye RE series, IDS Imaging Development Systems GmbH offers cables with a length of up to 10 m (see also USB uEye RE accessories).

The USB bus provides power supply with 5 V and 500 mA max. Many USB devices use the bus power and do not need external power supply (bus-powered devices).

Cable design

The following illustration shows the basic design of a shielded USB cable:

•D+/D-: data transfer

•+5 V/GND: power supply

Connector types

On the PC side, USB 2.0 cables are equipped with a standard A type plug (four pins) and on the device side either with a standard B plug (four pins) or a mini-B plug (five pins). In addition, some USB uEye camera models feature non-standard connectors which are lockable or splash water proof.

Achtung

Attention: The two USB ports may not be connected simultaneously. Even a not with a PC connected, additional USB 2.0 cable to the camera interferes by its antenna effect the operation of the camera, so that the camera does not boot (LED stays red), and in operation transfers no more data.
