Rs-644 Serial Communication - Basler A102K User Manual

2.6 RS-644 Serial Communication

The A102 is equipped for RS-644 serial communication via the frame grabber as specified in the
k
Camera Link standard. The RS-644 serial connection in the Camera Link interface is used to issue
commands to the camera for changing modes and parameters. The serial link can also be used
to query the camera about its current setup.
The Basler Camera Configuration Tool (Basler CCT+ for short) is a convenient, graphical interface
that can be used to change camera modes and parameters via the serial connection. The
configuration tool is installed as part of the camera installation procedure shown in the booklet that
is shipped with the camera. Section 4.1 provides some basic information about the configuration
tool. Further instructions for using the tool are included in the on-line help file that is installed with
the tool.
Basler has also developed a binary command protocol that can be used to change camera modes
and parameters directly from your application via the serial connection. See Section 4.2 for details
on the binary command format.
2.6.1 Making the Serial Connection
Frame grabbers compliant with the Camera Link specification are equipped with a serial port
integrated into the Camera Link interface that can be used for RS-644 serial communication. The
characteristics of the serial port can vary from manufacturer.
The port must have the following settings: 8 data bits, no parity, 1 stop bit, baud rate = 9600 bps
If you are using the Basler CCT+ to configure the camera, the tool will detect the characteristics
of the serial port on the frame grabber and will determine the appropriate settings so that the tool
can open and use the port.
In order for the Basler CCT+ to detect and use the port, the characteristics of the port
must comply with the Camera Link standard and the DLL called for in the standard
must be present.
If you are configuring the camera using binary commands from within your application software,
your software must be able to access the frame grabber serial port and to determine the
appropriate settings so that it can open and use the port. Please consult your frame grabber's
documentation to determine the port access method and the port characteristics.
