• Mesh Point Mode
• Mesh End Mode
Mesh Point Mode: it is the default mode for the FM unit. Each unit in the field that is not connected
to the wired LAN backbone must be set in Mesh Point Mode.
Mesh End Mode: in the Fluidmesh network, an FM unit that is connected to the main wired LAN
must be set in Mesh End Mode. The Mesh End unit is the junction point between the wireless network
and any IP-based wired network.
Regardless of its configuration, any FM unit comes from the factory with a unique unit ID with the
following format:
5.a.b.c
where the triplet (a,b,c) unambiguously identifies the unit and cannot be changed. The unit ID is
used to identify the units throughout the Web-based Graphical User Interface (GUI).

5.2.1 Network Addressing
The Fluidmesh layer 2 addressing allows configuring each FM unit and each device connected to
the FM units according to the IP address class used within the private LAN to which the Mesh End
unit is connected. A sample network configuration is shown in Fig. 5.2.
The Fluidmesh network logically becomes part of the private LAN where (usually) the control room
resides. Therefore, both the FM units and any other edge device should be provided with a private
LAN IP address and will be accessed through that specified IP address.
Consider the example depicted in Fig. 5.2 where the private LAN IP ad- dress class is 192.168.150.0
with netmask 255.255.255.0. Each device is configured with an IP address belonging to this class.
Please note that each IP address must be univocal within the entire network to avoid ad- dress
conflicts. The default IP address of each FM unit is 192.168.0.10 with netmask 255.255.255.0.
Finally, please note that the default factory- set 5.a.b.c unit IDs are still valid and used to
unambiguously identify each FM unit.
