Configuration Interface (CameraLink

®

)

A CameraLink

®

camera can be controlled by the user via a RS232 compatible asynchronous

serial interface. This interface is contained within the CameraLink

®

interface as shown in Fig.

5.30 and is physically not directly accessible. Instead, the serial communication is usually routed
through the frame grabber. For some frame grabbers it might be necessary to connect a serial
cable from the frame grabber to the serial interface of the PC.
