Setting up a MasterBus network
All devices that are suitable for MasterBus are
marked by the MasterBus symbol.
MasterBus is a fully decentralized data network for
communication between the different Mastervolt system
devices. It is CAN-bus based which has proven itself as a
reliable bus-system in automotive applications. MasterBus
is used as power management system for all connected
devices, such as the inverter, battery charger, generator
and many more. This enables communication between the
connected devices, for instance to start the generator when
the batteries are low. MasterBus reduces complexity of
electrical systems by using UTP patch cables. All system
components are simply chained together. Therefore each
device is equipped with two MasterBus data ports. As only
a few MasterBus cables are needed, installation and
material costs are reduced importantly.
New devices can be added to the existing network easily.
Consequently the MasterBus network is highly flexible for
extended system configuration. Mastervolt also offers
several interfaces like the Modbus interface, making even
non-MasterBus devices suitable to operate in the
MasterBus network. For central monitoring and control of
the connected devices Mastervolt offers different panels,
like the full colour MasterView System panel. All monitoring
panels can be used for monitoring, control and
configuration of all connected MasterBus equipment.
CAUTION!
Never connect a non-MasterBus device to the
MasterBus network directly! This will void
warranty of all MasterBus devices connected.

How to set up a MasterBus network
Every MasterBus device is equipped with two data ports.
When two or more devices are connected via these ports,
a local data network called the MasterBus is formed. Keep
the following rules in mind:
Place a terminating device on both network ends.
OK
Connections between the devices are made by
standard straight UTP patch cables.
OK
At least one device in the network must be MasterBus
powering (see specifications). As all powering devices
are galvanic isolated, multiple powering devices are
allowed.
OK
Do not make ring networks.
Do not make T-connections in the network.
