Ethernet topologies
The BCL 558
i
can be operated as a single device (stand-alone) 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 with star topology
The innovative further development of the BCL 558
i
with integrated switch functionality
offers the option of networking multiple bar code readers of type BCL 558
i
with one another.
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.
The maximum length of a segment (connection from the hub to the last participant) is limited
to 100m.

Ethernet with linear topology
Up to 254 bar code readers can be networked. For this purpose, each participating BCL 558
i
is assigned the respective network address via the display and the control panel or the
webConfig tool. This address must be specified by the network administrator. Alternatively,
the BCL 558
i
can also be configured as a DHCP client and then automatically receive its
address from a DHCP server.
Information on the necessary configuration steps can be found in chapter 10.
