5.7.5 USER1_PIN and USER2_PIN

The PIN CODES used to authenticate NFC configuration updates by USER1 or USER2 can –

and should - be changed from their default settings.

To do so, follow these steps:

 Request an update of the PIN code by setting Bit 6 (USER1_PIN) or Bit 7 (USER2_PIN)

in the SECURITY configuration group of the CONFIGURATION_SELECTION register

 Specify the currently active NFC PIN in the REQUEST_AUTHENTICATION register to

authenticate the request

 Specify the new NFC PIN in the USER1_PIN register (if updating the PIN for USER1)

or the USER2_PIN register (if updating the PIN for USER2).

After that, click the connected ECO 200 harvester 5 times in each direction to provide the

required energy for the update.

Make sure that the new PIN code is properly noted especially when changing

USER1_PIN. For security reasons, it is not possible to reset USER1_PIN after it

has been changed.

Figure 50 below shows the structure and the byte order of the USER1_PIN and USER2_PIN

registers together with the default PIN codes for USER1 and USER2.
