Bus Out For The Bcl 500 I; Table 7.5; Pin Assignment Bus Out - Leuze electronic BCL500i Technical Description

7.2.5 BUS OUT for the BCL 500
To set up the Leuze multiNet plus network with additional participants, the BCL 500
available another interface in the form of an RS 485.

Table 7.5:

Notice!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. The
signal lines must be stranded in pairs.
Termination of the RS 485 interface at the master
The RS 485 interface must always be externally terminated at the master with the use of a
T-connector and a terminating resistor (see chapter 13 "Type overview and accessories").
Termination of the RS 485 interface on the slave
On the last network device, the Leuze multiNet plus network (RS 485 interface) should be
terminated with a terminating resistor (see chapter 13 "Type overview and accessories") on
the BUS OUT socket.
Attention!
The BCL 500i
socket and via an external M12 T-connector! For further information, see chapter 7.4.3 and
