5.2 Fixed 64-bit Address
In the event setting the Network Identifier is not possible, but the 64-bit address is known, you can enter that fixed
address along with non-zero Rx Timeout. The name becomes a local reference only. The 64-bit address will be
automatically used by the BB2-7040 any time this device is referenced.
5.3 Search String
A method used by some ZigBee devices for identification is including an ASCII string, such as device serial number, in
every data stream sent by that device. When this method is used, enter the string to search for and the byte offset
indicating the location in the packet where the search should begin. It is expected that the search string will always begin
in a fixed location within the packet. A non-zero Rx Timeout must also be entered to signal that this device entry is now
valid.
The Rx Timeout is the amount of time that must elapse with no packet received from the device after which the mapped
BACnet object will be flagged with a Fault status, and the object’s reliability code set to indicate device timeout.
