7.5.2 RS 232/RS 422 (HOST / BUS IN)
5-pin, M12 plug (B-coded) or terminal block for connecting to an RS 232/RS 422 interface.
Figure 7.2: RS 232/RS 422 connection
Table 7.2: RS 232/RS 422 pin assignment (HOST / BUS IN)
The two switching inputs/outputs, SWIO1 and SWIO2, are configured as follows by default:
Switching output SWIO1: Position value invalid
Switching input SWIO2: Teach Preset
NOTICE
SWIO1 and SWIO2 as switching output
 At the outputs of the BPS (SWIO1 and SWIO2), no switching outputs may be connected from external
sensors/devices.
The switching output of the BPS may otherwise malfunction.

(Housing)
Connection cable shield.
The shield of the connection cable is on the
thread of the M12 plug or on the screw fitting of
the cable bushing.
The thread or the screw fitting is part of the
metallic housing. The housing is at the potential
of the functional earth via pin 5.
NOTICE
Use ready-made connection cables!
 If possible, use the ready-made cables from Leuze electronic; see table 14.4.
 No ready-made cables are available for the connection to the RS 422 interface; see chapter "Connec-
tion cables for the RS 422 interface".
