2.5 Laser safety notices
1) Use as safety-related component within the safety function is possible, if the component combination is designed corre-
spondingly by the machine manufacturer.
NOTE
Do not modify or otherwise interfere with the device!
Do not carry out modifications or otherwise interfere with the device.
The device must not be tampered with and must not be changed in any way.
The device must not be opened. There are no user-serviceable parts inside.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.

3.1 The BCL 8 bar code reader
The BCL 8 bar code reader is a laser scanner with integrated decoder for all commonly used bar codes,
e.g. 2/5 Interleaved, Code 39, Code 128, EAN etc., with an extremely small housing.
The many possible configurations of the device allow it to be adapted to a multitude of reading tasks. Due
to the small dimensions of the unit and its large reading field, the BCL 8 may also be used in highly
constrained spaces.
For information on technical data and characteristics, refer to Chapter 4.
3.2 Stand-alone operation
The BCL 8 bar code reader is operated as a "stand-alone" device. It is equipped with a 5-wire cable with
open ends or a 5-pin M12 connector for the electrical connection of the supply voltage, the interface and
the switching input.
With MA 8.1 connection unit
The MA 8.1 connection unit simplifies the electrical installation of the bar code reader in stand-alone oper-
ation with an RS 232 interface.
For details on the connection units, see Chapter 5.
With MA 8-01 connection unit
The MA 8-01 connection unit simplifies the electrical installation of the bar code reader in stand-alone
operation with an RS 485 interface.
For details on the connection units, see Chapter 5.
3.3 Daisy chain network
A daisy chain is a network based on the RS 232 interface. All devices, which consist of a transmitter and
a receiver, are connected to one another to form a ring. The transmitter of one device is directly connected
to the receiver of the next device until all devices are connected together to form a ring. One device
performs the task of the host system.

Description
Leuze electronic GmbH + Co. KG BCL 8 11
Ideally, all BCL 8 devices are to be connected to one another with MA 8.1 connection units so that:
• the voltage supply of the BCL 8/MA 8.1 is ensured.
• TxD to RxD of the RS 232 is established from one BCL 8 to the next (host).
• the switching outputs and inputs are connected (optional).
A maximum of seven BCL 8 devices may be operated in the daisy chain together with one host. Further
information is available from your Leuze sales office.
