Murata Electronics North America XDM2140 ユーザーズマニュアル
9.3.3.1 Configuration Change Flag (CCF)
The Configuration Change Flag (CCF) bit is set high when the network ID is changed. Note that when
the network ID is changed over the air (using the XML-API), the entire network synchronously changes
over to the new network ID. There is no delay between when the XML-API command is received and
when XDM2140 changes over to the new network ID. The CCF bit is set high when the new network ID
becomes active. The CCF bit is cleared when the XDM2140 receives a XDM2140 Information Get
request (Command 0x07), a getParameter Time command, a getParameter XDM2140 State command,
or the XDM2140 is reset.

9.3.5 Parameter Type 0x04 - Join Key
The join key is needed to allow a XDM2140 on the network. The join key is specific for the network and
used for data encryption. This parameter is only valid for a Set Parameter command. Upon receiving this
request, the XDM2140 stores the new join key in its persistent storage. The XDM2140 must be reset in
order to begin using the new join key.
