QUICK REVIEW
The Digital DC 10x10A is a MasterBus based input
and output module. It controls maximum 10 fused
DC channels with currents up to 10A or maximum
100A when the 10 channels are linked.
It provides the MasterBus network (see chapter 4)
with information about the state of the fuses and
devices. A MasterBus display enables you to view
this information, see section 3.3.

consistent with the intended purpose. Mastervolt
is not liable for any damage resulting from the
above.
2.3 ORGANIZATIONAL MEASURES
The user must always:
•have access to the user's manual;
•be familiar with the contents of this manual. This
applies in particular to this chapter, Safety
Guidelines and Measures.
2.4 MAINTENANCE AND REPAIR
1 If the electrical installation is switched off during
maintenance and/or repair activities, it should be
secured against unexpected and unintentional
switching on:
•switch off all charging systems;
•switch off the connection with the batteries;
•be sure that third parties cannot reverse the
measures taken.
2 If maintenance and repairs are required, only
use original spare parts.
2.5 GENERAL SAFETY AND INSTALLATION
PRECAUTIONS
•Connection and protection must be done in
accordance with local standards.
•Do not work on the Digital DC 10x10A or system
if it is still connected to a current source. Only
allow changes in your electrical system to be
carried out by qualified electricians.
•Check the wiring at least once a year. Defects
such as loose connections, burned cables etc.
must be corrected immediately.

OPERATION
6October 2010 / Digital DC 10x10A / EN
3 OPERATION
3.1 CONTROL
Control of the Digital DC 10x10A is largely
MasterBus based. This means you need a display
like shown in section 3.3 for controlling this switching
device.
3.2 HARDWARE OVERRIDE
For security reasons the channels are equipped with
a 15A conventional hardware fuse. The 15A fuses
have two positions each. These enable choosing
three different configurations manually. The table
shows the fuse positions with according meaning.
Position Mode
Normal (MasterBus) position:
MasterBus controls up to 10A of the
output
Manual override:
Always On,
Hardware fused
Manual override:
Always Off
WARNING
Manual Override overrides light voltage
settings, refer to sections 5.2.2 and 5.2.4.
With Manual Override Always On the DC
input is connected to the output directly
(fused). 12V devices in a 24V system are
then supplied with 24 V and can get
damaged!
3.3 MASTERBUS DISPLAYS
Mastervolt offers several ways of displaying your
MasterBus data. Shown is the MasterView System
Figure 2: MasterView System panel
Another way of displaying and configuring your
MasterBus devices is the MasterView System
software, shown for Digital DC application. See
figure 3.

MASTERBUS
EN / Digital DC 10x10A / October 2010 7
4 MASTERBUS
4.1 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.
4.2 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.

MASTERBUS
8October 2010 / Digital DC 10x10A / EN
4.3 HOW TO SET UP A MASTERBUS NETWORK
Every device that is suitable for the MasterBus
network is equipped with two data ports. When two
or more devices are connected to each other
through these ports, they form a local data network,
called the MasterBus.
Keep the following rules in mind:
Figure 4: UTP patch cable
Figure 5: Two Terminators
Figure 6: Power supply
Figure 7: No ring networks
Figure 8: No T-connections
Do not make T-connections in the network.
Do not make ring networks.
The electric power for the network is supplied by
the connected MasterBus devices.
At least one device in the network should have
powering capabilities (see specifications).
One powering device can power up to three non-
powering devices.
As all powering devices are galvanic isolated,
multiple powering devices are allowed.
OK
As with all high speed data networks, MasterBus
needs a terminating device on both ends of the
network.
Terminating

Connections between the devices are made by
standard straight UTP patch cables. Mastervolt
can supply these cables. These cables are also

5.2 CHANNEL MODES
Eight channel modes are selectable for easy
configuration, omitting unwanted options.
WARNING
In a 24V system, modes Light 12V and
Switched Light 12V will change to 24V in
Manual Override Always On (section 3.2).
5.2.1 Conventional
The conventional mode is used only for switching
the channel On/Off. See section 5.3 for channel
mode options. In Conventional mode the output
voltage equals the input voltage, there is no PWM on
this channel.
Application: navigation Electronics, refrigerator.
5.2.2 Light 12V
The Light 12V is convenient for 12V lighting without
built in switch. A correction for short voltage dips has
been built in. At a voltage supply of 24V, the Light
12V mode is still possible. The light intensity can be
adjusted by MasterBus configuration. Fade modes:
•dimming,
•fading out,
•fading in and out.
Manual Override overrides the Light 12 V setting,
see section 3.2.
Application: navigation lights and ceiling lights.
5.2.3 Light 24V
See light 12V, now for 24V lighting. At a voltage
supply of 12V, the Light 24V mode is not convenient.
5.2.4 Switched light 12V
The Switched light 12V is convenient for 12V lighting
with a built in switch. The option Minimum Current is
omitted to prevent an unwanted alarm at switch off.
With a voltage supply of 24V, the Switch light 12V
mode is still possible.
Application: reading light with built in switch.
5.2.5 Switched light 24V
See Switched light 12V, now for 24V lighting. At a
voltage supply of 12V, the Switched light 24V mode
is not convenient.
5.2.6 Motor
This function features an optional 1 second ramping
up setting. Application: cooling fan or toilet pump.
5.2.7 Bilge pump float
Function for bilge pump with floating switch. The
bilge pump includes a float switch enabling the pump
when soaked, with option Always On.
