3.3.4：Super SN Tutorial

1：Entrance​

See the menu Tools->Super Serial Number, as shown below:

2：Supported Features​

  • Supports writing serial number to any Flash block, such as Flash Memory, EEPROM, OTP, etc.

  • Big number support 1~64 (not enough can continue to increase) bytes of sequence number writing, you can freely configure the length of the write.

  • Big number supports end-of-serial number setting to avoid duplicate serial numbers during the production process。

  • Support serial number file import (xlsx table parsing, support more than 1 million lines).

    • Serial number file import does not limit the length of the serial number.
    • Serial number file import supports big number writes.
    • Serial number file import supports writing of very long strings of serial numbers.
    • Serial number file import supports setting the offset address, and the number of single imports.

  • Supports writing real time (PWX1 only).

tip

When importing from a file, the default is to import using the small end mode, with the low address on the left.

caution

Real-time time function, PWX1 device only, before production, please make sure the time of PWX1 has been synchronized, if not, please use the client to connect to the PWX1 device, it will automatically synchronize the time, and synchronize the time before production, Super Serial Number will not check whether the address is overlapped with other or not, because the consideration of the possibility of intentional combination of actions, but it will verify that the range of addresses is within the valid range.

3：Big number​

Serial Number Write Address: Set the write address of the serial number, which can be freely configured.

Serial Number Length: supports 1~64 bytes length, freely configurable.

Serial Number Starting Value (Small End Mode): Sets the starting value of the serial number.

Step of sequence number (small end mode): Sets a single increment of the sequence number.

Sequence Number End Value (Little Endian Mode): Sets the end value of the sequence number.

tip

Big number is an enhancement to Power Writer's default 4-byte serial number to compensate for the following shortcomings of the default serial number:

  • Default Serial Number Function: the length is limited to four bytes.
  • Default sequence number function: no end value judgment.
  • Default Serial Number Function: No arbitrary region can be set.

4：External File Import​

External file import supports xlsx table, when importing table, you need to set the rows and columns for serial number reading, the default is to start reading from 0 rows and 0 columns.

5：Manufacturing time​

The PWX1 device supports writing real time, see as shown above.

6：Notes​

  • When importing from an external file, the cells must all be strings, if they are not strings, an error will be reported.
  • When importing serial numbers from external files, you need to ensure that the serial number length is uniform.
  • External serial number import defaults to the little endian.
