Basler Binary Protocol Library

Basler racer Camera Link cameras have blocks of mapped memory space known as registers. By
reading values from the registers, you can determine basic information about the camera and
information about the camera's current settings. By writing values to the registers, you can control
how the camera's features will operate.
If you use the Basler pylon software described in the previous section, the camera's register
structure is hidden. With pylon, a series of function calls allows you to change camera parameter
settings without the need to know anything about the register that underlies each parameter.
If you desire, you can also change the camera parameter settings and control the camera by directly
accessing the camera's register structure. The Basler Binary Protocol Library (BBPL) provides
functions that allow you to read data from or write data to the camera's registers. The BBPL is an
extension of the clALLSerial/clSerial API defined in Appendix B of the Camera Link Standard
version 1.1 or higher. The BBPL adds convenience functions to this API that allow you to read from
and write to the registers in Basler Camera Link cameras. The read and write requests are
transmitted to the camera via a serial link between the camera and the frame grabber; the serial link
is part of the standard Camera Link interface.
Sample code showing how to use the BBPL along with supporting documentation can be
downloaded from the Basler website:
When using the BBPL to change parameter values, you will need to know the details of the
camera's register structure. For details of the register structure, refer to the racer-specific document
Register Structure and Access Methods for Camera Link Cameras (AW001270). The document can
be downloaded from the Basler website.
Note that if you are using an earlier Baser Camera Link camera that was originally
designed to work with the Basler Binary Protocol II (e.g., the A400k, L400k, L800k,
and the sprint), you can now use either the BBPL or the Binary Protocol II to
access the camera's registers.
