Electrical connection
The standard devices are connected with 6- or 10-pin connector piece to X31 or X32,
respectively. For hand-held scanners, BCL 8 and BPS 8 with 5 V DC supply (from the MA)
on pin 9, the 12-pin X30 PCB connection is available as well.
By using an additional cable (cf. "Type overview and accessories" on page 61), the system
connection can be established on M 12 or 9-pin Sub-D, e.g., for hand-held scanners.

Service interface (internal)
Figure 7.6:
Following activation, this interface enables access via the RS 232 to the connected Leuze
device and the MA for configuration using the 9-pin Sub-D. The connection between the
fieldbus interface and the device interface is switched off during access. The fieldbus itself
is, however, not interrupted as a result.
The service interface can be accessed once the MA
and features a 9-pin Sub-D connector (male). A crossed RS 232 connection cable is required
to make the RxD, TxD and GND connections. A hardware handshake via RTS, CTS is not
supported at the service interface.

Attention!
For the service PC to function, the RS 232 parameters must be the same as those of the
MA. The Leuze standard setting of the interface is 9600Bd, 8N1 and STX, data, CR, LF.
Notice!
To configure the devices connected to the external interface, e.g., BCL 8 (JST plug connec-
tor "X30"), a cable specially configured for this purpose is necessary. The service switch must
be in the "DEV" or "MA" position (Service Leuze device/MA).
