iButton Serial Number(ID) Writer/Programmer – Assigning New 64-bit IDs to RW1990 iButton

Description

The global unique serial number (ID) of an iButton is written into the chip by laser during manufacture. But now we have another way to assign new ID to the RW1990 programmable iButton by using this serial port ID writer and tm1990b software.

The serial port ibutton writer and RW1990 writable ibuttons are available from our website as well as the programming software. The difficulty is the 8-bit CRC code of item 4 and it is very difficult to understand the calculation of CRC code for common users. Luckily we have tools or formula to generate the CRC given a 48-bit string and the family code. It is really simple and the ID assigning process can be done in seconds.

Key Features

  • Assign any new ID as you want, such as ‘010000000000003d‘(01 is the family code + 3d is the CRC code);
  • You dont even need a ibutton for it but just get the ID nunber, you can write it(meaning that you can clone a ibutton after you see the ID number of it. Amazing! Think of what you can do!)
  • The RW1990 programming ibutton can be rewritable without limits of times;
  • Easy to operate and the ID can be written in seconds;
  • ID programming software supports Windows OS including Windows XP\Vista\7\8\8.1\10.
