DFAPP: Ethernet Gateway for Domino
bus
DFAPP module is a gateway between the Ethernet network
and the Domino bus; through BDTools and BDWizard sup-
port programs it is possible to perform all usual operations
such as the assignment of module addresses the program-
ming of the system functions reading and editing of operat-
ing programs updating firmware of modules and more yet
through the Ethernet network both locally and remotely.
The same operations can be also performed in wireless
mode connecting directly to DFAPP module through WiFi
or through an acces point properly configured.
DFAPP module also allows to control the home automation
system through applications iCasaMia and ACasaMia avail-
able for free on the related stores; thanks to this last possi-
bility DFAPP module is a user-friendly solution for the con-
trol and management both locally and remotely of lighting
automation air conditioning scheduled operations loads
control energy consumption and more again.
DFAPP module allows to manage most of the variables of
the Domino bus specifically:
digital inputs status
status and command of real outputs
value of analog inputs (eg. temperature)
setting of analogue outputs (eg. dimmer)
status and command of virtual points
management of scheduled times
DFAPP module features a rel time clock with backup bat-
tery capable of retaining the time in case of main power
supply failure.
As said above through DFAPP module it is possible to pro-
gram Domino modules both locally and remotely as well
as update their firmware. DFAPP module is open to future
developments being itself completely upgradable.
Some LEDs visible from the panel provides an indication of
the operating status of the module as described in the fol-
lowing table:
LED Color Function
POLL Green It flashes one time per second to indicate that
the module is active
VAR Green It flashes in case of change of state of a
Domino digital input module
BUS F. Red Fixed On when Domino bus failure occurs (if
DFAPP is separately powered)
MOD F. Red On for 5s when a module does not answer to
a message
TX Yellow It flashes when the communication is active
RX Red It flashes when the communication is active
DFAPP module features a terminal block for the connection
to the Domino bus.
This DFAPP version is based on Raspberry PI4 (RPI4B) a
high performance single board computer; due to the high
current consumption of RPI4B it is strongly recommended
to avoid powering the module through the power supply ter-
minals on the module (12-24V). Instead it is recommended
to use the provided wall mount power supply and connect-
ed to the USB-C to the socket on the left side of DFAPP.
Unlike previous versions the power supply cannot be de-
rived from the bus.

The following schematic diagram shows the connections
required by DFAPP module.
