8 DEVA at a glance
DEVA is capable to perform tasks and react
to certain events on the basis of a scheduled
program and an event list. The interaction with the
environment triggers a set of actions spanning from
playing a audio le to streaming video. In systems
with more than one DEVA, scheduled actions – such
as playing audio les – can be synchronized to the
Global Positioning System clock.
The DEVA System Manager provides full
management of DEVA: it is a web-app installed into
the Powersoft DEVA Director – PDD.
The DEVA System Manager allows you to
perform on-y actions, such as:
fLight – switch the light on or off.
fStream live announcements – from the

Getting Started |13
Getting Started
Before proceeding to the placement of the
DEVA on site (ref. Chapter “26 Mounting kits”), we
recommend to setup the device “on the desk”.
The initialization phase can involve the manual
setup of the device; once properly initialized and
congured, DEVA has been designed to be self-
operating and remotely managed.
The initialization workow includes:
1. Battery assembly on the DEVA;
2. SIM assembly (optional);
3. DEVA start-up;
4. Initialization of the connections (networking);
We suggest to follow the instruction on this
manual in order to properly setup the DEVA.
10 Battery assembly
DEVA comes with a battery pack already installed
into its battery compartment (ref. FIGURE 3). The
battery pack shall be properly connected before
operating.
1. Open the battery compartment.
2. Verify that the battery presents no
failures by probing with a multimeter. If
the portrayed value is <10.8 Vdc, please
contact Powersoft’s customer service.
Sulfation occurs when a lead acid battery is
deprived of a full charge.
3. Plug the battery:
fconnect the red + (positive) faston to the
battery positive plug (beware the 4 A fuse);
fconnect the black – (negative) faston to the
battery negative plug.
4. Place the battery temperature probe far from
the electric plugs, wherever into the battery
compartment.
5. Reposition the compartment cover and tightly
screw the six hex screws.
In order to ensure full operability,
Powersoft recommends to fully charge the battery
before starting the initialization procedure.
The battery charge can be achieved by means of
either:
fan external power supply capable to deliver
20 VDC and up to 3 Amax (e.g. solar panel, DC
power supply unit, etc.) connected to the
Phoenix MC 1,5/ 2-ST-3,81 (ref. FIGURE 1 #16);
fa 18 VDC, 1 Amax power supply plugged to the
5.5 mm coaxial plug (ref. FIGURE 1 #8);
fa 48 VDC PoE+ IEEE 802.3at Type2 via the
Ethernet connection (ref. FIGURE 1 #11).

14 |DEVA |User Guide
12 Start-up
Once the battery has been properly assembled
(ref. Chapter “10 Battery assembly”), DEVA can be
switched on. By default, DEVA starts-up when any
external power supply (i.e. solar panel, DC power
supply unit, PoE+ IEEE 802.3at Type 2) is plugged in.
When the DEVA is connected to an external
power supply, the system starts charging the internal
battery: when the power supply delivers more than
12 VDC the DEVA power up automatically.
In approximately 90 seconds the operating
system completes the bootstrap procedure and
makes the device ready to work. During the
bootstrap you can hear a long beep coming from
the DEVA: the presence of this signal means that the
system is booting.
When the front LED starts blinking (DEVA
looking for a Wi-Fi connection), the start-up
procedure is complete.
12.1 DEVA start-up without external power supply
In case no power supply is available and DEVA
is off, you can switch on the DEVA by means of the
ON/OFF button (ref. FIGURE 5).
1. Push on the ON/OFF button and keep it
pressed:
2. the green LED switches solid on;
3. still keep the ON/OFF button pressed until the
green LED starts blinking (3 s approximately);
4. release the ON/OFF push button: the
bootstrap procedure takes place and a long
beep is emitted.
Be aware that the start-up procedure without
power supply will not take place if the battery
charge is below 12 VDC.
11 SIM card assembly (optional)
DEVA supports GSM and GPRS communication
protocols via a standard SIM – Subscriber Identity
Module – card*.
DEVA works properly even without a SIM board,
but sms notication and data connectivity via GPRS
are disabled.
Follows these instructions in order to install the
SIM card.
1. Unlock the SIM by disabling the PIN request
during power up: this can be made easily by
inserting the SIM into a mobile phone and
disabling the PIN request.
2. Access the dashboard compartment and gently
slide and tilt the SIM card tray (ref. FIGURE 4).
3. Insert the SIM card into the slot and reposition
the tray.
* Not included in the package. Ask to your local IT providers.
The GPRS communication features shall be
activated and managed through the DEVA System
Manager (refer to the DSM user guide).

13 Shut down
Usually you don’t need to shut down the DEVA
for maintenance: the management can be performed
by means of the DEVA System Manager.
1. Access the DEVA on site and remove the
dashboard cover on the back of the DEVA (ref.
FIGURE 3).
2. In order to completely shut down the DEVA
we suggest to unplug any external power
supply (e.g. solar panel).
3. On the DEVA dashboard, identify the On/Off
push-button (ref. FIGURE 5): keep pressed the
button until the three rear LEDs start blinking.
4. Release the On/Off push-button and wait until
all the LEDs switch off (approximately one
minute). The system will emit 2 short beep
followed by a long beep to warn you about the
shut down in progress.
14 Networking
DEVA can be set as a stand alone device or
integrated into any existing wired, wireless or mixed
network. A proper network setup includes:
fPowersoft DEVA Director – PDD. The PDD
is a personal computer implementing a custom
GNU/Linux based operating system: the PDD
provides a client-server environment that
allows the user to easily manage the network
of DEVA.
Both the DEVA and the PDD must be
connected to the same network; this means
that all devices have to be either hosted by the
same Wi-Fi access point, or wired to the same
Ethernet switch and sharing the same subnet
and IP range.
fDHCP server (often already implemented into
routers and access point). Both the DEVA and
the PDD are set to dynamic IP addressing.
fEthernet switching (often already implemented
into routers and access point) with a proper
number of ports for wired connectivity;
fWi-Fi access point for wireless connectivity;
fOne or more DEVA.
In the following pictures we suggest some network
topologies oriented to a domestic environment,
where the router/AP implements both the DHCP
server and the Ethernet switch.
14.1 DEVA in a wireless LAN
The DEVA are connected wireless to the access
point; the PDD must use a wired connection to
the access point. Any further client on the wireless
network can manage the network of DEVA: in order
for the client to manage a DEVA it must connect to
the PDD.

16 |DEVA |User Guide
14.2 DEVA in a wired LAN
Both the DEVA and the PDD must be connected
to the switch. The DHCP on board of the router
assigns a unique IP address to each DEVA and PDD
so they belong to the same subnet.
Through the DSM implemented in the PDD it
is possible to manage the network of DEVA, set
schedules and events, monitor the performance and
launch an announcement on specied DEVA.
Refer to the DSM documentation for more
information on how to congure the DEVA network
parameters and the PDD in order to match your
network environment.

15 Initialization
The initialization is performed by means of the
PDD – Powersoft DEVA Director –, by connecting
the DEVA to the local network through a wired or
wireless connection.
You may need the following equipment:
fPowersoft DEVA Director – PDD;
fDHCP ser ver or a router with DHCP capability;
fEthernet switch with a proper number of ports
for wired connectivity;
fAccess point – AP – for wireless operating.
15.1 Initialization in a wireless LAN
By default DEVA tries to connect to a Wi-Fi
network whose SSID is set to POWERSOFT.
In order to perform the initialization procedure
we recommend to set your AP as follow.
1. Connect the PDD and the AP to the same
LAN: ensure that they share the same IP range.
2. Log-in the PDD and launch the browser.
3. Point your browser to the IP address of the
access point and enter its control panel.
4. Modify the SSID of the Access Point to
“POWERSOFT” and password “powersoft”.
Save and reboot the Access Point. While
rebooting you will loose the connection: after
some second, refresh the page on the browser
and reconnect to the AP.
5. By default DEVA looks for the POWERSOFT
Wi-Fi network. Through the AP control panel
you should monitor all connected devices.
6. In the PDD, open the DEVA System
Manager: on the browser address-bar write
http://localhost:8080
7. Log in the DEVA System Manager: the
administrator account has the following default
credentials:
username: admin
password: admin
Once logged in, the DEVA System Manager
shows the latest saved network conguration:
since you are going to initialize your network, no
one DEVA is listed.
8. Click the button Discovery on the Toolbar: the
DEVA System Manager will start seeking and
connecting new devices on the network.
Now you can start using DEVA.
15.2 Initialization in a wired LAN
In order to perform the initialization procedure
in a wired network environment, all devices have to
be connected to a DHCP server (possibly through
an Ethernet switch) in order to receive unique IP
addresses within the same subnet.
1. Connect the PDD and the DHCP server to
the same network: ensure that they share
the same IP range, i.e. the PDD receives its IP
address from the local DHCP server.
2. Connect each DEVA to the same network of
your PDD and switch them on (ref. Chapter
“12 Start-up”).
3. Now follow the same procedure described in
Chapter “15.1 Initialization in a wireless LAN”
starting from point 6.

22 Actions and Players
22.1 Actions
Depending on the version, DEVA performs a set
of dened actions:
fPlay audio
fSwitch the light on/off
fTake photo
fStream video
fRecord audio
fPlay the radio (FM/web)
fReproduce live streaming
fNotify with a message (sms/email)
22.2 Players
DEVA provides four audio players that manage
respectively:
1. live stream of audio
2. playback of single audio le
3. playback FM radio
4. playlist of audio les
The four players can be active at the same time,
but only two of them will play simultaneously,
according to their priority:
live stream > single le > FM radio > playlist
hiGh priority > low priority
The four audio players are layered on the basis of
the playback priority:
fthe playback of a live streaming (either an audio
le or from the microphone) has the priority on
the playback of an audio le from the library;
fthe playback of a single audio le has the priority
on the playback of the FM radio;
fthe playback of an FM radio has the priority on
the playback of a playlist.
The player with the lower priority plays in
background (i.e. lower in volume) when a high
priority player starts playing.
NOTE: The default behavior can be overridden
by changing the volume level during the playback.
Each player provides independent volume control.
The playback volume of each player is a fraction
(expressed in percentage) of the master volume.
