DIP switch settings
If the bus address is set for
CerPass reader protocol
,
the reader addresses
1 . . . 16
can be used.
If the bus address is set for
UCI reader protocol
,
only the reader addresses
1 . . . 4
can be used.
The method of address counting and addressing (number of readers to be connected) depends on the
controller / reader interface used and must be taken into account.
7.2
Setting the address (Clock/Data)
There is no need to select a reader address when the Clock/Data interface is used.
The Clock/Data interface allows only one reader to connect with the interface.
7.3 Communication
interface and protocol selection
The communication interface has to be selected either to communicate with
intelligent controllers or via RS485 bus to connect to a reader interface or
Clock/Data interface.
Within the communication interface there are different protocols selectable.
