Long distances and a choice out of three paralell image channels with high frequency color streams, have bben the requirements on NetLink PLUS.
Three different interfaces have been implemented for this application: images of color cameras with high framerates were acquired over CameraLink interface and converted from Bayern pattern to RGB color space in realtime. The multi-port GigabitEthernet interface enables transfer distances of app. 100 meters from port to port, as well as a flexible system of a video network. Finally the color images were output over USB2 interface to a connected PC with display.
The solution is a small, easy to implement OEM product, which is highly flexible and adaptable to new and changed requirements.
