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.
