…
Note: Once the node is locked with BAD CBKE Data Token, it cannot work as Smart Energy node
and its CBKE Data Token cannot be changed and erased. There is no way to change or erase
CBKE Data Token. Even Factory Reset does not erase its CBKE Data Token. Please be sure to
lock the CBKE Data Token with valid certificate.
3.3 Configuring Install Code
User can set the ‘Install Code’ for joining a ZE20S device to the SE network. Install Code is used to
generate Pre-configured Link Key. The Pre-configured Link Key is derived from the Install Code using the
MMO hash function. Install code is optional. While the Trust Center (coordinator) can communicate with
any node other than the Trust Center, non-Trust Center nodes with common Install Code in a Smart
Energy Network can communicate with each other. In ZE20S node, user can set Install Code by
AT+INSTALLCODE. Install Code must be 6/8/12/16 byte hexadecimal.
Example)
AT+INSTALLCODE=AABBCCDDEEFF<CR> # Install Code must be 6/8/12/16 byte
# hexadecimal
OK<CR> # Response
AT+INSTALLCODE<CR>
INSTALL CODE: AABBCCDDEEFF<CR> # Install Code locked
OK<CR> # Response
Note: Once the Install Code is set, it cannot be changed and erased. There is no way to change or
erase Install Code. Even Factory Reset does not erase Install Code. Please be sure to input the
Install Code with care.
3.4 Setting up ZE20S as a Coordinator
A coordinator relays messages and can act as a parent to other nodes. Every personal area network
(PAN) must be started by a node acting as the coordinator. In general, this device is always powered on.
To set up the ZE20S to work as the coordinator, please follow the steps as below
 Configure the CBKE Data Token
 Configure the ZE20S node type as the coordinator
 Optionally, select the channel mask. Otherwise, the ZE20S will use the default channel mask.
