Serial Communication

This board supports the asynchronous full-duplex serial communication between the camera and the frame grabber.

Serial Link Types

For cameras using the 26-pin Camera Link connectors, two differential line pairs of the camera cable are dedicated to the serial communication, one for each direction:

For cameras using the 14-pin Camera Link connectors, namely the PoCL-Lite cameras, the downstream serial communication link does not use a dedicated line pair but, instead, is embedded in the Channel Link.

This board supports both types of serial links. The default type specifies the "Standard" serial link: this setting is adequate for all the cameras but the PoCL-Lite.

For PoCL-Lite cameras, the alternate type must be selected by setting the value POCL_LITE to the SerialLinkA or SerialLinkB parameters.

Note. When connecting a PoCL-Lite camera, it is mandatory to assign the value LITE to the SerialLinkA or SerialLinkB parameter

The requirement remains valid even if the application doesn't intend to use the serial communication.

Serial Link Functionalities

The application software controls the serial communication channel through the standardized API defined by the Camera Link standard.

Alternatively, it can also be controlled using virtual COM ports. Therefore, the application must set the appropriate values to the parameters SerialControlA and SerialControlB respectively.
