5.1 Controller
(Manual)
The SREL3 ADV system is connected to the network via Ethernet. The
Ethernet connection is PoE-capable, so an external power supply unit is
not essential.
It is possible to use the system as a gateway in the virtual network. The
controller establishes a connection to the VN host server to do so. The VN
host server forwards changed authorisations (programming requirement)
and data from the LSM database to the controller. This means that
complete, time-consuming loading of the database is no longer required;
instead, the controller collects the provided data when an identification
medium is detected (pull principle). The entire system is programmed via a
single interface – the controller.
The SREL3 ADV is also available in a ZK variant, which extends the
system's functions to include time zone control and event logging (access
lists).
Three available screw terminal inputs ensure that the controller is flexible
in its use.

The built-in screw terminal relay output can activate any system and open
an electric door, for example.
An IP address needs to be issued using USB when the controller is
programmed for the first time. Once the IP address is issued, a USB
connection is no longer needed. The controller's configuration can be
modified over the network instead.
The built-in backup battery ensures that the programmed settings are
maintained after a power failure and guarantees that the controller
continues to function without any limitations once power is restored.
