Overview
The code reader is provided with the following connections:
• PWR / SWIO: A-coded, 12-pin, M12 connection for operating voltage, switching inputs/outputs,
RS 232/RS 422 interface
• HOST: D-coded, 4-pin, M12 connection for the Ethernet/PROFINET connection

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 electronic of-
fers 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.
