The system has a RJ45 input for connection to remote emergency microphone workstations (VAE series DBE01 // DBEVF) and monitored
according to Standard EN54-16.
Connect the microphone workstation to socket rJ45 through a UTP CAT5 cable. The connection between the two RJ45 pins to the cable end
must be 1-to-1.

RJ45 Connector for connection to external emergency microphone workstation (DBExx
series). This connector carries both the audio signals and data link from and to the
external microphone workstation. Connection is monitored and the system reports a fault
in case the communication with the microphone workstation is lost due to short-circuit or
cable cutting.
Proprietary connection for connection to the dedicated microphone workstations only
Use 8-pole UTP CAT5 cable, 4 pairs. Head the RJ45 connectors 1-to-1
4.l RS485 Serial connection
The system implements an RS485 communication port for connection to remote devices with dialogue through protocol, described in the
specific manual. The following figure describes the connection between the AE300 and an external device, through RS485 port. The jumper to
terminate the line is located behind the terminal. With the jumper inserted, the line is terminated. With the jumper not inserted, the line is not
terminated.
