2.6.1 Point-to-Point
Using a Point-to-Point layout, the data is transmitted on the Main interface as well as on the
Auxiliary interface. The Main interface can be selected for RS232 or RS485 full-duplex
communications. Two different layouts are available according to the DS8100A reader model
used for the connection.
Standard Models
When On-Line operating mode is used, the reader is activated by an External Trigger
(photoelectric sensor) when the object enters its reading zone. In the following case, the
signal is passed to the DS8100A by the C-BOX 100, which also supplies the system.

Fieldbus Models
In this case no External Trigger is used and the C-BOX 100 only supplies the reader. The
DS8100A (Ethernet model) is connected to a fieldbus remote Host. It can be activated by a
signal generated by the remote Host or always be active if working in Automatic operating
mode.
