PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

5.6.10 ZGP_SEC_CONFIG

The ZGP_SEC_CONFIG register determines the security mode used by PTM 535BZ for the

transmission of ZGP telegrams.

The ZGP_SEC_MODE field defines how the security key is encrypted in the commissioning

telegram. By default, PTM 535BZ uses the ZA09 key to encrypt the security key. Optionally,

PTM 535BZ can use an Install Code (IC) to encrypt the security key. Refer to the Zigbee

Green Power specification [3] for a description of this feature.

The ZGP_KEY_SELECTION field determines which of the two security keys (SECURITY_KEY1

or SECURITY_KEY2) is used to authenticate ZGP data telegrams. SECURITY_KEY1 is used by

default.

The ZGP_BUTTON_COMMISSIONG determines if the LRN button can trigger the transmission

of a commissioning telegram. By default, this is possible. If transmission of commissioning

telegrams is disabled, then the ZGP radio channel has to be selected using ZGP_TX_CHAN-

NEL.

Figure 44 below shows the structure of the ZGP_SEC_CONFIG register.
