Serial Communication
This board supports the asynchronous full-duplex serial communication between the camera and the frame grabber.
It exists two implementations of the serial communication link:
- One for cameras using the Base, Medium, Full, or 80-bit configurations.
- One for cameras using the Lite configuration.
Serial Link for the Base, Medium, Full, or 80-bit configurations
For cameras using the Base, Medium, Full, or 80-bit configurations, two differential line pairs of the first camera cable are dedicated to the serial communication, one for each direction:
- SerTFG— Downstream (camera to frame grabber) serial communication link
- SerTC— Upstream (frame grabber to camera) serial communication link
Serial Link for the Lite Configuration
For cameras using the Lite configuration, the downstream serial communication link doesn't use a dedicated line pair but, instead, is embedded in the Channel Link.
Selection of the Serial Link Type
By default, the serial link is configured for the Base, Medium, Full, or 80-bit configuration.
When using Lite configuration cameras, it is mandatory to select the alternate type by setting the value POCL_LITE to the SerialLinkA or SerialLinkB parameters.
This action must be performed:
- Before the first use of the serial communication
- Before the initial configuration and activation of the corresponding MultiCam channel
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.
