2 Parameters
2.2 List of parameters
Note: KHP: Know-How Protection
Even if know-how protection is set, parameters in this list can be read and written to.
Description: OEM exception list (p7764[0...n] for setting parameters that should be excluded from know-how protection.
p7764[0...n], with n = p7763 - 1
Dependency: The number of indices depends on p7763.
Refer to: p7763
Note: KHP: Know-How Protection
Even if know-how protection is set, parameters in this list can be read and written to.
Description: Sets the action to be executed for NVRAM data.
At the end of the action the value is automatically set to 0.
Value: 0: Inactive
1: Load NVRAM data to parameters
2: Load parameters to NVRAM
3: Reset
Notice: After action p7770 = 1 no more pulses may be enabled.
After action p7770 = 2, it is essential that parameters are backed up (p0977 = 1) and that a warm restart is then
performed (p0009 = 30, p0976 = 2, 3). This will apply the values written.
Note: If value = 1:
This action loads the NVRAM data to the parameters.
If value = 2:
This action loads the parameters to the NVRAM.
If value = 3:
This action sets parameters p7771 ... p7774 to the factory setting.
It is recommended to avoid placing unnecessary load on the subsequent upload/download operation.
Description: Displays the actual serial number of the memory card.
The individual characters of the serial number are displayed in the ASCII code in the indices.
Notice: An ASCII table (excerpt) can be found, for example, in the appendix to the List Manual.
Note: Example: displaying the serial number for a memory card:
r7843[0] = 49 dec --> ASCII characters = "1" --> serial number, character 1
r7843[1] = 49 dec --> ASCII characters = "1" --> serial number, character 2
r7843[2] = 49 dec --> ASCII characters = "1" --> serial number, character 3
r7843[3] = 57 dec --> ASCII characters = "9" --> serial number, character 4
r7843[4] = 50 dec --> ASCII characters = "2" --> serial number, character 5
r7843[5] = 51 dec --> ASCII characters = "3" --> serial number, character 6
r7843[6] = 69 dec --> ASCII characters = "E" --> serial number, character 7
r7843[7] = 0 dec --> ASCII characters = " " --> serial number, character 8
