For communication with the superior host system, the corresponding TCP/IP protocol
(client/server mode) or UDP must be selected.
Further information on commissioning can be found in chapter 12.
Ethernet – star topology
The MA 208
i
can be operated as a single device (standalone) in an Ethernet star topology
with individual IP address.
The IP address is either set permanently via the RS 232 interface or assigned dynamically
via a DHCP server.

Ethernet – linear topology
The innovative further development of the MA 208
i
with integrated switch functionality offers
the option of connecting multiple gateways of type MA 208
i
to one another without direct
connection to a switch. In addition to the classic "star topology", a "linear topology" is thus
also possible.

Each participant in this network requires its own unique IP address, which must be assigned
to it via the RS 232 interface. Alternatively, the DHCP procedure can be used.
The maximum length of a segment (connection from the hub to the last participant) is limited
to 100 m.
