Device construction of the BCL 8
Figure 3.1: Device construction of the BCL 8
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 wide reading field, the BCL 8
may also be used in highly constrained spaces.
Information on technical data and characteristics can be found in 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 five-
core 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 connector unit
The MA 8.1 connector unit simplifies the electrical installation of the bar code reader in
stand-alone operation with an RS 232 interface.
For details on the connector units, see chapter 5.
With MA 8-01 connector unit
The MA 8-01 connector unit simplifies the electrical installation of the bar code reader in
stand-alone operation with an RS 485 interface.
For details on the connector 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.
Ideally, all BCL 8 devices are to be connected to one another with MA 8.1 connector 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.

Notice!
Please note that the size of the bar code module influences the maximum reading distance
and the width of the reading field. Therefore, when selecting a mounting location and/or the
bar code label, take into account the different reading characteristics of the scanner with var-
ious bar code modules.
For different reading task and connection requirements, the BCL 8 is available in various

4.4.2 Reading fields
Notice!
Please note that the actual reading fields are also influenced by factors such as labelling ma-
terial, printing quality, scanning angle, printing contrast etc., and may thus deviate from the
reading fields specified here. The origin of the read distance always refers to the front edge
of the housing of the beam exit.
