Device construction of the BCL 8
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.

Description
3.2
Stand alone operation
The BCL 8 bar code reader is operated as a "stand-alone" device. It is equipped with a fivecore 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.

Attention, laser radiation!
Follow the safety notices in chapter 2.5 on page 7!
Accessories
A variety of mounting systems are available which you can order separately from Leuze
electronic (see chapter 5.1 and chapter 5.4).
Mounting the BCL 8
There are three basic mounting arrangements for the BCL 8 (see chapter 4.3):
• using the dovetail strips and the corresponding mounting accessories BT 8-0.
• using the mounting threads on the back- and underside of the devices.
• using the two ∅ 4.4mm through holes.
Mounting the MA 8.1 connector unit
You can mount the MA 8.1 connector unit according to your needs by using the two bore
holes. Subsequently, connect the BCL 8 with the connector unit via the respective cable
(see separate data sheet for MA 8.1).
6.2.1
Device arrangement
In order to select the right mounting location, several factors must be considered:
• size, orientation, and position tolerance of the bar codes on the objects to be scanned.
• the reading field of the BCL 8 in relation to the bar code module width.
• the resulting minimum and maximum read distance from the respective reading field
(For specific information, please refer to chapter 4.4).
• alignment of the bar code reader for avoiding reflections.
• distance between BCL 8 and host system with respect to the interface.
Notice!
The best reading results are obtained when
• the reading distance lies in the middle area of the reading field.
• there is no direct sunlight and extraneous light is avoided.
• the bar code labels are of good print quality and have good contrast ratios.
• you do not use high-gloss labels.
• the bar code is moved past the reading window with a rotational angle > approx. 15°.
• the laser beam is narrowed down for its respective reading task in order to avoid
reflections on shiny components.

Installation
Notice!
With front beam exit, the beam exit on the BCL 8 is nearly vertical to the reading window;
with lateral beam exit, the beam exit is at 15° from vertical. The bar code label must be rotated by > 10° to avoid a total reflection of the laser beam in the case of glossy labels.

 When selecting a mounting location, pay attention to
• maintaining the required environmental conditions (temperature, humidity).
• possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
• lowest possible chance of damage to the scanner by mechanical collision or jammed
parts.
• possible extraneous light influence (no direct sunlight).

Connection
Attention!
The BCL 8 bar code reader is completely sealed and cannot be opened.
Do not try to open the device under any circumstances, as this voids both protection class
IP 67 and the warranty.
Before connecting the device please ensure that the supply voltage matches the value printed on the nameplate.
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BCL 8 and the corresponding connector units must have a secure electrical insulation according to IEC 60742
(PELV). For UL applications: only for use in class 2 circuits according to NEC.
Take care to connect the protective conductor correctly to the housing screen. Error-free
operation is only guaranteed when the device is properly earthed.
If faults cannot be corrected, the device should be removed from operation and protected
against possible commissioning.

Measures to be performed prior to the initial commissioning
 Before commissioning, familiarize yourself with the operation and configuration of the
device(s).
 Before connecting the supply voltage, recheck all connections and ensure that they
have been properly made.
7.2
Function Test

After connecting the operating voltage, the BCL 8 performs an automatic "Power On" function test. Afterward, the green status LED on the top side of the BCL 8 lights up. Only then
are any saved customer-specific settings active.
Interface
Proper function of the interface can be tested easiest in service operation using the service
interface with the "BCLConfig" programming software and a notebook computer.
Using the "Online" commands, important device functions can be checked, e.g. proper functioning of the laser.
Problems
Should problems occur during device commissioning, refer first to chapter 8.2. Should a
problem persist after checking all electrical connections and settings on the devices and

Setting the Parameters
You have now commissioned the BCL 8. Usually, you will have to configure it before you
can use it. Using the parameter options made available by the BCL 8, you may configure
the bar code reader to suit your individual area of application. For instructions regarding the
various setting options, refer to chapter 9 or to the online help of the BCLConfig program.
To operate the BCL 8, it is normally sufficient to set code type and code length in accordance
with the bar codes that are to be read. However, depending on the application, you will additionally activate the autoReflAct function and configure the switching inputs and outputs
according to your requirements.
The setting of code type and code length is usually accomplished by using the BCLConfig
program, see "Installing the BCLConfig software" on page 44.
To understand what is happening during the parameter setting, the following chapter 7.3.1
briefly explains the various parameter sets.
The setting of the parameters then takes place in the "service" operating mode, which is
described in chapter 7.3.2.
7.3.1
Parameter sets
factory default parameter set
This parameter set contains the default settings made ex works for all BCL 8 parameters. It
is permanently stored in the ROM of the BCL 8. The parameter set with the factory settings
is loaded into the memory of the BCL 8,
• the first time the device is commissioned after delivery;
• following the command "Factory Default" in the configuration program
(online command ’PC20’)
• if the checksums of the current parameter set are invalid.
Current parameter set
In this parameter set, the current settings for all device parameters are stored. When the
BCL 8 is in operation, the parameter set is stored in the EEPROM of the BCL 8. The current
set can be stored:
• by copying a valid parameter set from the host computer to the BCL 8;
• by an off-line setup using the BCLConfig configuration software and then subsequently copying to the BCL 8
The current parameter set is loaded into the memory of the BCL 8:
• each time the supply voltage is connected;
• following a software reset (online command ’H’).
The current parameter set is overwritten by the parameter set with the factory settings:
• by a parameter reset, see page 66.

Service Operating Mode
Setting the required parameters is carried out easiest in the 'Service' operating mode. The
operating mode Service provides the following defined operating parameters on the RS 232
interface, no matter how the BCL 8 is configured for standard operation:
•
•
•
•

8 data bits
1 stop bit
prefix: STX
postfix: CR, LF
Activating the service interface
The service interface can be activated by holding a defined bar code label ("Service", see
figure 7.1) in front of the reading window during power-up (initialization phase).
Bar code label "Service"
While the laser switches on for approx. 1s after power-up, the "Service" label is to be held
up in front of the bar code reader at a suitable read distance. When the device is in service
mode, the status LED flashes orange.
Connection
You can connect a PC or a terminal to the BCL 8 via the serial interface and configure the
BCL 8 through this connection. The connection is made using an RS 232 connection cable
that establishes the RxD, TxD and GND connections between PC and BCL 8.
If the BCL 8 is connected to a connector unit, you can establish the connection in the same
way in front of the connector unit. For the respective pin assignments, please refer to the
data sheet of the connector unit.

Error Handling
Error, warning and status messages of the BCL 8 are transmitted via the RS 232 interface.
Types of errors
Errors are divided up into the following types:
• Warnings
• Serious errors
Warnings
Warnings indicate temporary operating faults which do not affect the proper functioning of
the device.
Serious errors
Serious errors impair the proper functioning of the device. The device must be reinitialized.
Troubleshooting
Isolated warnings can be ignored, since the BCL 8 will continue to function properly.
Following a serious error, you should reinitialize the BCL 8. It will then usually again function
properly. If a hardware problem is present, the BCL 8 will not reinitialize.
Warnings and errors which occur frequently can be corrected easiest using the BCLConfig
software.
If you cannot correct faults and errors with the software, please contact a Leuze electronic

Mode
• Normal – mode (1) with optional laser beam narrowing
This is the standard mode without the reflector polling function.
• Reflector polling with auto activation reading gate – mode (2)
In this mode, the decoding of the label is automatically started after the scanning
beam to the reflector has been interrupted. Following successful decoding or
renewed detection of the reflector, the reading gate is automatically closed. If the
reflector is covered, the reading gate is automatically opened for decoding.
• Reflector polling without auto activation reading gate,
send an 'AR' command – mode (3)
In this mode, the decoding does not start automatically. Starting must be activated via
a control or via a switching input. This mode is of interest if a programmable logic controller (PLC) wants to know whether or not the scanning beam to the reflector is currently interrupted. If this is the case, the PLC can start the decoding by sending the +
command. The BCL sends an 'AR=1' command (freely configurable) if a reflector was
detected or it sends an 'AR=0' command (freely configurable) if no reflector is present.
• Reflector polling without auto activation reading gate, set the switch – mode (4)
Same as mode (3), except that the detection of whether or not a reflector is present is
passed on via the switching output. As in mode 3, decoding is not activated automatically; this is the task of the control.
• Reflector polling without auto activation reading gate,
send an 'AR' command and set the switch – mode (5)

Important Parameters
Reflector polling
Reflector polling (autoReflAct) is an operating mode in which no external sensor is required
for triggering. The scanner is activated and deactivated with the aid of a reflector (see Accessories) which must be mounted in the scanning range of the BCL 8.
For simple alignment in autoReflAct mode, please select the AutoReflAct Wizard.
Once called up, the wizard attempts to establish a connection to the connected BCL 8. If this
is successfully, please select one of the four reflector polling modes under "Mode" from the
menu which then appears. A screen similar to the following appears:
Figure 10.10: AutoReflAct Wizard
Upon activation of the "Search" button, the BCL 8 scans its reading field and attempts to find
a reflector. To do this, the reflector must be positioned in the reading field of the scanner.
After a reflector has been detected, it passes on the start position of the reflector in its
reading field.
The scanner is now ready for the AutoReflAct operating mode.
Attention!
If other reflective objects are located in the reading window of the scanner besides the reflector, the application is to be checked carefully, because these reflective parts could possibly cause a mistrigger in the scanner!
Notice!
The reflector should be mounted at a distance of max. 300mm from the BCL 8.

• the decoding result.
These values can be used to determine the decoding quality.
In addition to the output of the status information, the laser beam is used
to display the reading quality. Depending on how many labels were able
be extracted, the duration of the laser's "off" time increases.
If the reading quality is high, the laser beam flashes in brief, regular intervals. The worse the decoder decodes, the longer the pauses become during which the laser is switched off.

11.1.3 ’Online’ commands for parameter set operations
Definitions
• <BCC type> Type of checksum calculation.
’0’: No checksum
’3’: XOR checksum (mode 3)
• <PS type> Parameter set type
’0’: Current parameter set (data stored non-volatilely in the EEPROM)
’1’: Reserved
’2’: Standard parameter set (not changeable)
’3’: Operating values (data in the RAM, will be lost after reset)
• <Status> Mode of parameter processing
'0': Does not perform a reset following the write operation; no other parameters follow.
'1': Does not perform a reset following the write operation; other parameters follow.
'2': Subsequently performs a reset, no other parameters follow.
• <Start address> Relative address of the parameter within the parameter set

• Para0H = 31h, Para0L = 32h, Para1H = 33h, Para1L = 34h
Taking into consideration the maximum message length and the remaining command
parameters, a maximum of 123 bytes of parameter data (246 bytes of message data)
can be transmitted in a single operation.
Valid values: '0' … '9', 'A' … 'F'
• <Acknowledgement>:

• <Para0L> <Para0H>… <Para122L> <Para122H>:
Parameter-set data of the message. The sequence of the data is arranged identically
to the BCL 8, i.e. when a word is transmitted, first the low byte is sent then the high
byte. The parameter-set data is converted for transmission from HEX format to a 2byte-ASCII format. During the conversion, two ASCII characters - representing the
lower and higher nibbles - are created for each HEX value.

Description
The command transmits parameter data beginning with the set address
and stores it there in an intermediate buffer. If the status indicates that further messages follow, these are also stored in the intermediate buffer
before they are then stored under the corresponding parameter set type in
the EEPROM. The transmission can optionally occur with a block check
test of the message data.
