The newly added reader has not been brought into "Online Mode"
From the hardware tree right-click on the reader and select "Online Mode". The reader should now show up as online, and the user should be able to control the door operation.
**Note - If unable to put the readers into online mode, it is necessary to first make the controller active, as shown below. After selecting this, a reboot of the controller is necessary for the changes to take effect.
