The Processors in our example need the addresses of Sampler and Sink. They receive these from DDS via properties (sent in the step above):

##### 10. (optional) Use example command UI to check state of the devices
This example includes a simple utility to send command to devices and receive replies from them. The code in `runDDSCommandUI.cxx` (compiled as ex3-dds-command-ui) uses the DDSCustomCmd library to send "check-state" string to all devices, to which they reply with their ID and state they are in. This can be used as an example of sending/receiving commands or other information to devices.
This example includes a simple utility to send command to devices and receive replies from them. The code in `runDDSCommandUI.cxx` (compiled as ex3-dds-command-ui) uses the DDS intercom library to send "check-state" string to all devices, to which they reply with their ID and state they are in. This can be used as an example of sending/receiving commands or other information to devices.
To see it in action, start the ex3-dds-command-ui while the topology is running.
