Device / Boot / FirmwareCrcCheck Value

Every firmware is protected by a CRC. By default the firmware does a self test by calculating the CRC and verifying that it is correct. If the readers program memory is defect or the firwmare was not loaded completely/correctly this test will fail and the BootStatus bit 1 (=0x00000002) will be set.



Name Type/Size Description
- Enumeration (8 bits) Values:
  • Enabled (0xFF)
    This is the default setting.
  • Disabled (0x00)

    Depending on the reader hardware the CRC check may last some ms up to a second. Use this setting to avoid the CRC check and speed up the readers powerup time.

    When using this option you cannot be sure that the reader is working correctly.
