X33
RS 232 service interface
9-pin Sub-D connector
RS 232 interface for service/setup operation. Enables the connection of a PC
via serial null modem cable for configuring the Leuze device and the MA 238
i
.
S4
Rotary switch
Rotary switch (0 … F) for device selection
Standard setting = 0
S10
DIP switch
Service switch
Switch between service Leuze device (DEV), service fieldbus gateway (MA)
and operation (RUN).
Standard setting = operation.
J1, J2
Jumper

(interruption of connection between the two PWR M12 connectors of the
SWIO 1 or SWIO 2)
ATTENTION!
Several Leuze devices may not be connected to the MA 238
i
simultaneously, as only one
RS 232 interface can be operated.
