Termination of the RS 485 interface (BCL 601i)
The device operates as slave in the Leuze multiNet plus network. On the last physical participant, the
Leuze multiNet plus network (RS 485 interface) must be terminated with a terminating resistor (see
chapter 16 "Ordering information and accessories"). This prevents reflections on the Leuze multiNet plus
and improves the immunity to interference.

Leuze multiNet plus
The Leuze multiNet plus is optimized for fast transmission of scanner data to a primary host computer. The
multiNet plus consists physically of a two-wire RS 485 interface through which the multiNet plus software
protocol is controlled.
This makes wiring the network easy and inexpensive as slaves are looped through to one another in
parallel.
The BCL 600i can only participate as a slave in the Leuze multiNet plus on the BUS OUT socket
and via an external M 12 T-connector (see chapter 7.8.3 and see figure ).
