5. DSAB CONFIGURATION
This section introduces some concepts that are central to understanding and configuring a
network of DSAB-capable Dynon products. It then takes you through a series of simple steps to
configure your network, enabling data sharing and HS34 functionality. Do not proceed with
DSAB configuration until you perform all installation, calibration, and configuration steps for
each instrument with a display. Display-less instruments – such as the HS34 – cannot be fully
configured until DSAB is active, although their physical and electrical installation should be
complete.
Network Concepts
A few concepts must be
understood before
configuring a DSAB-
connected system. The
most important is that of
Dynon products as
providers of functions to
the network. These
various functions are
called roles. Some
products, such as the
HS34, only have one role
on the network; other
products can provide
multiple roles at a time.
When a device has been
assigned to provide a role
to the network, no other
device on the network can
provide that role at the
same time.

The table at right lists all available roles and the products which they can be assigned to. Again,
each role can be assigned to no more than one device on the network.
Another important concept is that of the Bus Master. A DSAB-connected network must have at
least one EFIS-based product (EFIS-D10A, EFIS-D100, or FlightDEK-D180), and only an EFIS-
based product can be assigned the Bus Master role. The Bus Master is the instrument which
manages communication on the network. Additionally, if Autopilot servos are installed, the Bus
Master is the Autopilot. While the Autopilot can be controlled from slave devices, if the Bus
Master is not present, the Autopilot will not function. If the Bus Master is turned off or fails, all
data sharing ceases, causing units to display internally-derived data only. When you first perform
DSAB network configuration on an EFIS-based instrument, that device is automatically assigned
the Bus Master role. Perform DSAB configuration on your primary EFIS-based instrument, as
the Bus Master is also the default provider for both the EFIS and Compass roles.
