3 Fast commissioning / operating principle
Below you will find a short description for the initial commissioning of the BCL 308 i . Detailed explanations
for all listed points can be found throughout this technical description.
3.1 Mounting the BCL 308 i
The BCL 308 i bar code readers can be mounted in two different ways:
• Via four M4x6 screws on the device bottom.
• Via a BT 56 mounting device in the fastening groove on the housing bottom.
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 308
i 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 308
i and the host system depending on which inter-
face is used.
• The correct time for data output. The BCL 308
i 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.
• The display and control panel should be very visible and accessible.
• For configuring and commissioning with the webConfig tool, the USB interface should be easily
accessible.
For specific information, please refer to Chapter 6 and Chapter 7.
3.3 BCL 308 i electrical connection
For the electrical connection of the BCL 308 i , 2 connection variants are available.
The voltage supply (18 … 30 V DC) is connected acc. to the connection type selected.
2 freely programmable switching inputs/outputs for individual adaptation to the respective application are
also available here. Detailed information on this topic can be found in Chapter 7.
NOTE
The beam of the BCL 308
i exits:
•Parallel to the housing base in the case of the line scanner
•At 105 degrees from the housing base in the case of the deflecting mirror
•Perpendicular to the housing base in the case of the oscillating mirror
In each case, the housing base is the black area in Figure 6.2. The best read results are obtained
when:
• The BCL 308
i is mounted in such a way that the scanning beam is incident on the bar code
at an angle of inclination greater than ±10° … 15° to vertical.
• The reading distance lies in the middle area of the reading field.
• The bar code labels are of good print quality and have good contrast ratios.
• You do not use high-gloss labels.
• There is no direct sunlight.

Cable fabrication and shielding connection
Remove approx. 78 mm of the connection cable sheathing. 15 mm of sheath of the shielded line must be
freely accessible.
Figure 3.6: Cable fabrication for MK 308 terminal hood
The shield is automatically contacted when the cable is lead into the metal screw fitting and fastened when
the cord grip is closed. Then lead the individual wires into the terminals according to the diagram. Wire end
sleeves are not necessary.
3.4 Preparatory settings – Ethernet
Connect the +18 … 30 V DC supply voltage (typ. +24 V DC); the BCL 308 i starts up.
As a first step, you need to set the communication parameters of the BCL 308
i . You can make the neces-
sary settings via the webConfig tool. Further information can be found in Chapter 10.
3.4.1 Manual configuration of the IP address
If your system does not include a DHCP server or if the IP addresses of the devices are to be set perma-
nently, proceed as follows:
Have the network administrator specify the data for IP address, net mask and gateway address of the
BCL 308
i .
Set these values on the BCL 308
i :
NOTE
The integrated parameter memory for the simple replacement of the BCL 308
i is located in the
MK 308. In the integrated parameter memory, both the settings and the network address are
saved and transmitted to a new device.
NOTE
In the case of Ethernet linear topology, the network is interrupted when the BCL 308
i is removed
from the MK 308.

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 308
i .
Via webConfig:
Configuration > Communication > Ethernet interface
Activate the DHCP = ON setting there.
NOTE
If the setting is performed via the webConfig tool, the BCL 308
i must be restarted. The set IP
address is only accepted and active after this restart.

3.4.3 Setting the 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 308
i 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 308
i
In TCP client mode, the BCL 308 i actively establishes the connection to the superior host system (PC /
PLC as server). The BCL 308
i 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 308
i deter-
mines when and with whom a connection is established!
With a BCL 308
i 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 superior host system (PC / PLC) actively establishes the connection and the
connected BCL 308
i waits for the connection to be setup. The TCP/IP stack requires information from the
user regarding the local port of the BCL 308
i (port number) on which the connection requests of a client
application (host system) are to be accepted. If there is a connection request and a connection is estab-
lished by the superior host system (PC / PLC as client), the BCL 308
i (server mode) accepts the connec-
tion. Data can then be sent and received.
With a BCL 308
i as TCP server, also set the following values:
• Port number for the communication of the BCL 308
i with the TCP client
The corresponding adjustment options can be found:
• Via webConfig:
Configuration -> Communication -> Host communication
3.4.5 UDP
The BCL 308 i requires from the user the IP address and the port number on which the communication
partner receives data. In the same way, the host system (PC / PLC) now also requires the set IP address
of the BCL 308
i 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 address 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
