4.1 Topology 
The Compact Reader communicates with the parent control unit via the RS-485 interface. Under 
this arrangement, the control unit is responsible for badge authorization checking and triggering 
access points. 
If this communication is interrupted, the Compact Reader automatically takes over the tasks of the 
control unit on a reduced basis; i.e., a simplified authorization check procedure and door functions 
are retained depending on the offline parameter settings.
