In the communication chain of a system, the access controller is integrated between the host
system and the peripheral devices.
It is possible to connect a maximum of eight readers to the access modular controller.
The four reader interfaces are divided into two physical buses. Interface 1 and 2 are on one
bus, and interfaces 3 and 4 are on the other bus. This gives the advantage in cabling: longer
cable lengths can be used (1200 m maximum per bus). Internally the buses are processed as
one interface. With this arrangement, you can connect all readers to one interface.
