NOTICE
Ready-made cables are available for all connections (see chapter 16.4 "Cables accessories").
Voltage supply, RS 232/RS 422 and switching inputs/outputs
The voltage supply (18 V … 30 V DC) is connected at the PWR / SWIO M12 plug.
The RS 232/RS 422 interface on the PWR / SWIO M12 plug is directly connected to the host.
To connect to other fieldbus systems, e.g., PROFIBUS, PROFINET, EtherCAT, etc., Leuze offers various
connection units (see chapter 7.6 "Connecting code reader to fieldbus").
Four freely programmable switching inputs/outputs for individual adaptation to the respective application
are also available on the PWR / SWIO M12 plug.
Standalone operation in Ethernet network
The code reader is operated as a "stand-alone" single device in an Ethernet star topology with individual IP
address. The host interface of the superior system is connected to the HOST M12 socket.
