2-2-4 Configure Daisy Chain (If Required by Application)
The creation and deletion of Daisy Chains occurs via UDP messages that are sent from the DDU user
interface to the readers. If a parent device recognizes that it has been configured in a Daisy Chain, it
creates the firmware connection, and then broadcasts UDP messages that contain all the information
needed by the user interface to produce a functional Daisy Chain configuration. The user interface will
only create a new Daisy Chain if it receives a broadcast from the Parent device with the Daisy Chain
information. The core communication between the user interface and the devices(s) is via the Parent
device. The firmware is responsible for connecting the Parent device to the Children devices and then
reporting the status.
A Daisy Chain consists of one Parent and one or more Children devices. The Children devices report
their data to the Parent, which then reports the data to the network, effectively allowing all readers to act
as one.
Error Handling
If the Parent reader in a Daisy Chain is turned off for more than one minute, a Disconnected notice will
appear in the dialog. This notice will disappear once the Parent reader is turned back on.
