    16 bit data can be processed more effectively on little endian hard- ® ware such as Intel processor based PCs.) When the camera is set for 16 bit output, 16 bits of data will be transmitted for each pixel but only 10 bits are effective (see Section 3.8). BASLER A620...

    Normally, the data values for a 16 bit component would range from 0x0000 to 0xFFFF. However, when an A600f camera is set for 16 bit output, only 10 bits are effective. Therefore, the highest data value you will see is 0x03FF indicating a signal level of 1023. BASLER A620...

  • Page 103: Smart Features And The Smart Features Framework

    Features Framework 6.1 What are Smart Features Smart features are features unique to Basler cameras. Test Images, the Cycle Time Stamp, and the CRC (Cyclic Redundancy Check) Checksum are examples of Basler smart features. In some cases, enabling a smart feature will simply change the behavior of the camera. The Test Image feature is a good example of this type of smart feature.

    • A method of accessing the camera’s DCAM register structure. We strongly recommend that you use the Basler BCAM 1394 Driver (V1.7 or higher) along with the Basler Smart Features Framework software to access the registers. (See Section for more information about the SFF Software.)

    Note that instead of performing two single quadlet write operations, a block write can be performed. * The last three zeros in this quadlet represent a timeout value. When the time out value is “000” as it is on the A620f, it means that advanced features are always available. BASLER A620...
