BCL 608i
34
The BCL 608i is designed as an Ethernet device (acc. to IEEE 802.3) with a standard baud rate of 10/
100 Mbit. A fixed MAC ID is assigned to each device by the manufacturer; this ID cannot be changed. The
device automatically supports the transmission rates of 10 Mbit/s (10Base T) and 100 Mbit/s (10Base TX),
as well as auto-negotiation and auto-crossover.
The device features multiple M12 plugs / sockets for the electrical connection of the supply voltage, the
interface and the switching inputs and outputs.
The device supports the following protocols and services:
• TCP / IP (Client / Server)
• UDP
• DHCP
• ARP
• PING
For communication with the superior host system, the corresponding TCP/IP protocol (client/server mode)
or UDP must be selected.
Ethernet – star topology
The device can be operated as a single device (standalone) in an Ethernet star topology with individual IP
address.
The IP address can either be set permanently via the display or webConfig tool or assigned dynamically
via a DHCP server.

Ethernet – linear topology
The innovative further development of the device with integrated switch functionality offers the option of
connecting multiple bar code readers of this type to one another without direct connection to a switch. In
addition to the classic star topology, a linear topology is thus also possible.
This makes wiring the network easy and inexpensive as slaves are looped through to one another in
parallel.
Each participant in this network requires its own unique IP address which must be assigned via the display
or webConfig tool; alternatively, the DHCP method can also be used.
The maximum length of a segment (connection from the hub to the last participant) is limited to 100 m.
