WHAT IS MASTERBUS?
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. This CAN-bus based
communication network 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
gives the possibility for communication between the
connected devices, for instance to start the
generator automatically 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. When
two or more devices are connected to each other
through these data ports, they form a local data
network, called the MasterBus. The results are a
reduction of material costs as only a few electrical
cables are needed and less installation time.
For central monitoring and control of the connected
devices Mastervolt offers a wide range of panels
which show full status information of your electrical
system at a glance and a push of a button. Three
different panels are available, from the MasterView
Easy up to the full colour MasterView System panel.
All monitoring panels can be used for monitoring,
control and configuration of all connected MasterBus
equipment.
New devices can be added to the existing network in
a very easy way by just extending the network. This
gives the MasterBus network a high degree of
flexibility for extended system configuration, not only
today, but in the future as well!
Mastervolt also offers several interfaces, making
even non-MasterBus devices suitable to operate in
the MasterBus network. For direct communication
between the MasterBus network and a product
which is not from Mastervolt, the Modbus interface is
recommended.
CAUTION: Never connect a non-
MasterBus device to the MasterBus
network directly! This will void warranty of
all MasterBus devices connected.

EVENT BASED COMMANDS
With MasterBus each device can be configured to
initiate an action at another connected device. This
is done by means of event based commands, see
chapter 5 for explanation.
An event is a
condition
to be met at which you want
another device
to perform a
task
. In chapter 5 the
Events are explained.
