Example 3 : Double reader and double interface configuration
In case of more interfaces connected to an Access Control Panel, it is necessary to assign each a different address , which will
be sent on the bus wiegand ( see par.25). This is done by setting the parameter "Code" on the menu Settings to each device. The
factory wiegand address is 1.
(*) : Despite having a different wiegand address, it is advisable to use different input ports on the access control to avoid overlaps
caused by simultaneous activations.
