The following is an overview of the Link tab of captureOEM.
Bandwidth Limit (Mbps)
When enabled, this feature will place an upper bound on the amount of aggregate bandwidth the camera may use for image data. Of course, each individual packet associated with image data must (by definition) be sent at the full link speed but over a longer period of time, the amount of overall bandwidth consumed by the camera, will not exceed this limit. This feature may be particularly useful, if you plan on using multiple cameras on a single bus, or connecting the camera onto a bus that has another high throughput device.
