Below you will find a short description for the initial commissioning of the BCL 308i. Detailed
explanations for all listed points can be found throughout this technical description.
3.1 Mounting the BCL 308i
The BCL 308i bar code readers can be mounted in two different ways:
•Via four M4x6 screws on the bottom of the device.
•Via a BT 56 mounting device in the fastening groove on the bottom of the housing.
3.2 Device arrangement and selection of the mounting location
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 308i in relation to the bar code module width.
• The resulting minimum and maximum reading distance from the respective reading
field.
• The permissible cable lengths between the BCL 308i and the hos
on which interface is used.
• The correct time for data output. The BCL 308i should be positioned in such a way
that, taking into consideration the time required for data processing and the conveyor
belt speed, there is sufficient time to e.g. initiate sorting operations on the basis of the
read data.

3.4 Preparatory Ethernet settings
Connect the +18 … 30VDC supply voltage (typ. +24VDC); the BCL 308i starts up.
As a first step, you need to set the communication parameters of the BCL 308i. You can
make the necessary settings via the webConfig tool. Detailed information on this topic can
be found in chapter 10.
3.4.1 Manually setting the IP address
If your system does not include a DHCP server or if the IP addresses of the devices are to
be set permanently, proceed as follows:
Have the network administrator specify the data for IP address, net mask and gateway
address of the BCL 308i.
Set these values on the BCL 308i:
Via webConfig:
Configuration -> Communication -> Ethernet interface
Notice!
If the setting is performed via the webConfig tool, the BCL 308i must be restarted. Only
after this restart is the set IP address accepted and does it become active.
3.4.2 Automatically setting the IP address
If your system includes a DHCP server that is to be used to assign the IP addresses,
proceed as follows:
Activate the DHCP Client mode in the BCL 308i.
Via webConfig:
Configuration -> Communication -> Ethernet interface
Activate the DHCP = ON setting there.

Fast commissioning / operating principle
3.4.3 Defining Ethernet host communication
The Ethernet host communication enables the configuration of connections to an external
host system. Both UDP as well as TCP/IP (in either client or server mode) can be used. The
connection-free UDP protocol is used primarily to transfer process data to the host (monitor
operation). The connection-oriented TCP/IP protocol can also be used to transfer
commands from the host to the device. With this connection, the data is backed up by the
TCP/IP protocol itself.
If you would like to use the TCP/IP protocol, you must also define whether the BCL 308i is
to operate as a TCP client or as a TCP server.
Both protocols can be activated simultaneously and used in parallel.
Contact your network administrator to determine which communication protocol is used.
3.4.4 TCP/IP
Activate the TCP/IP protocol
Set the TCP/IP mode of the BCL 308i
In TCP client mode, the BCL 308i actively establishes the connection to the primary host
system (PC / PLC as server). The BCL 308i requires from the user the IP address of the
server (host system) and the port number on which the server (host system) accepts a
connection. In this case, the BCL 308i determines when and with whom a connection is
established!
With a BCL 308i as TCP client, also set the following values:
•IP address of the TCP server (normally the PLC/host computer)
•Port number of the TCP server
•Timeout for the wait time for an answer from the server
• Repetition time for renewed communication attempt following a timeout
In TCP server mode, the primary host system (PC / PLC) actively establishes the connection and the connected BCL 308i waits for the connection to be setup. The TCP/IP stack
requires information from the us
which the connection requests of a client application (host system) are to be accepted. If
there is a connection request and a connection is established by the primary host system
(PC / PLC as client), the BCL 308i (server mode) accepts the connection. Data can then be
sent and received.
With a BCL 308i as TCP server, also set the following values:
•Port n
umber for the communication of the BCL 308i with the TCP client
The corresponding adjustment options can be found:
•Via webConfig:

Leuze electronic BCL 308i 17
Fast commissioning / operating principle
3.4.5 UDP
The BCL 308i requires from the user the IP address and the port number at which the
communication partner receives data. Correspondingly, the host system (PC / PLC) now
also requires the set IP address of the BCL 308i and the selected port number. This assignment notifies both communication partners of which port the data is received on.
Activate the UDP protocol
Also set the following values:
•IP a
ddress of the communication partner
•Port number of the communication partner
The corresponding adjustment options can be found:
•Via webConfig:
Configuration -> Communication -> Host communication
3.5 Further settings
After the basic configuration of the operating mode and the communication parameters, you
need to carry out further settings:
• Decoding and processing the read data
Define at least one code type with the desired settings.
•Via webConfig:
Configuration -> Decoder
• Control of the decoding
Configure the connected switching inputs according to your requirements. To do
this, first set the I/O mode to Input and then configure the switching behavior:
•Via webConfig:
Configuration -> Device -> Switching inputs/outputs
• Control of the switching outputs
Configure the connected switching outputs according to your requirements. To do
this, first set the I/O mode to Output and then configure the switching behavior:

Operation of BCL 308i
After voltage (18 … 30 V DC) has been connected to the switching input, a read process is
activated. In the standard setting, all common code types for decoding are released; only
the 2/5 interleaved code type is limited to 10 digits of code content.
If a code is moved through the reading field, the code content is decoded and forwarded to
the superior system (PLC/PC) via the Ethernet.

The BCL 308i can be operated and configured using the integrated webConfig tool via the
USB service interface; alternatively, the bar code rea
tion commands via the host/service interface.
The BCL 308i needs a suitable activation to start a read process as soon as an object is in
the reading field. This opens a time window ("reading gate") in the BCL 308i for the read
process during which the bar code reader has time to detect
Alternative activation options include online commands via the host interface and the In the
basic setting, triggering takes place through an external reading cycle signal. Alternative
activation options include online commands via the host interface and the autoReflAct func-
tion.
Through the read operation, the BCL 308i collects additional useful pieces
nosis which can also be transmitted to the host. The quality of the read operation can be
inspected using the alignment mode which is integrated in the webConfig tool.
An optional display in English with buttons is used to operate the BCL 308i as well as for
visualization purposes. Two LEDs provide additional optical information on the cu
ating state of the device.
The two freely configurable switching inputs/outputs SWIO1 and SWIO2 can be assigned
various functions and control e.g. activation of the BCL 308i or external devices, such as a

4.4 Reading techniques
4.4.1 Line scanner (single line)
A line (scan line) scans the label. Due to the opt. opening angle, the reading field width is
dependent on the read distance. Through the movement of the object, the entire bar code
is automatically transported through the scan line.
The integrated code fragment technology permits twisting of the bar code (tilt angle) within
certain limits. These are dependent on the transport speed, the scanning rate of the scanner
and the bar code properties.
Areas of application of the line scanner
The line scanner is used:
• when the bars of the bar code are printed in the conveying direction ('ladder
arrangement').
•with bar codes having very short bar lengths.
• when the ladder code is turned out of the vertical position (tilt angle).
• when the reading distance is large.
