PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

5.1.1 Users

The NFC interface architecture of PTM 535BZ supports two different users with different levels

of access rights. The user with the higher level access rights is called USER1; the user with

the lower level access rights is called USER2.

USER1 has the right to change all available configuration options. The available configuration

options for USER1 are defined by the register USER1_CONFIGURATION_OPTIONS.

USER2 can only change a subset of all available configuration options. The available config-

uration options for USER2 are defined by the register USER1_CONFIGURATION_OPTIONS.

USER1 can change (restrict) the available configuration options of USER2 so that USER2

cannot change certain configuration options or execute certain functional requests. This re-

striction is done by clearing the corresponding bits in the USER2_CONFIGURATION_OPTIONS

5.1.2 PIN codes

USER1 authenticates requests by means of the 4 byte USER1_PIN while USER2 will authen-

ticate requests by means of the 4 byte USER2_PIN.

USER1_PIN can only be changed by USER1 after providing the currently active USER1_PIN.

The default value of USER1 PIN is 02:00:35:E5.

USER2_PIN can be changed by USER1 after providing the currently active USER1_PIN or by

USER2 after providing the currently active USER2_PIN.

The default value of USER2 PIN is 03:00:35:E5.

USER1_PIN and USER2_PIN should be changed from their factory default values to prevent

unauthorized access to the NFC configuration as described in Chapter 5.7.5.

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.

Table 9 below summarizes the USER PIN codes.

Table 9 – NFC USER PIN codes

PTM 535BZ provides a 16 bit hash of the 32 bit USER1_PIN (USER1_PIN_HASH) and the 32

bit USER2_PIN (USER2_PIN_HASH). This hash can be used by a configuration tool to check

if it possesses the correct USER1_PIN or USER2_PIN as described in Chapter 5.7.5.1.
