9 USB CAMERA OPTION
All cameras are shipped with a USB interface for control and readout of the camera. This allows
the camera to be operated with or without a Framegrabber, and helps diagnose system problems
when a framegrabber is being used. A camera control program comes with the camera, which
uses the serial port supported by the Framegrabber, if it supports the standard Camera Link DLL,
or may be used with the USB port in situations where the camera link serial port is not available,
or too slow. In order to use this option you must be using an operating system that supports
USB, and have the correct drivers installed. Currently this is supported under Windows and
Linux only.
The USB port may also be used to obtain image data from the camera, you may select full
images or an ROI to reduce the image rate. The camera supports USB 2.0, which provides up to
about 40 MBytes/sec transfer rates. You will probably get less, it depends on your computer;
typically the transfer rate is more than 30 Mbytes/sec.
