Hardware Manual
Description
“eDAS”is a 16-bit, fully programmable data logger designed to offer a
comprehensive solution to structural and environmental monitoring
needs wherever signals to be recorded are expected to be slowly
changing.
The system core is represented by a 8-channel module that digitizes
and formats input signals in order to send them to and / or record them
in the internal memory of the system.
This module is enclosed in a robust, IP65-rated case, fitted with
connectors and cable glands, that hosts a user-replaceable main battery
and a backup battery as well.
“eDAS”logger, that basically comes as a standard 8-channel unit, can
be used as a remote acquisition system and, thanks to the internal
battery and low consumption features, is suitable for virtually any
installation place.
Similarly, it can operate as a distributed multi-channel system made up
of as many as 255 units, deployed in proximity with sensors, inter-
connected via a RS422 / RS485 serial BUS. The BUS will also work as a
means to feed all the networked units from an additional 12/24 Vdc
power supply consisting in a battery with relevant charger and, if any, a
photovoltaic panel (Powerbox).
Further, it is possible to increase the number of channels available by
implementing a number of multiplexers in order to get standard
versions of 16- or 32-channel data loggers.
On request, larger customized systems are assembled in special cases
according to the monitoring project needs.

In order to prevent power waste when not in use, EDAS loggers are
normally delivered with separate battery. Users have to fit the battery
(or any compatible power supply source) in place before starting any
operating procedure.
Main battery
Standard equipment includes a “D” size 3,6V - 13,5Ah Lithium battery
Type Li-SOCl2 (Lithium)
Brand SAFT
Model LSH 20
The average estimated operating life is 4 to 6 months, but always
consider that this estimation depends on:
how often the loggers is activated
how many and what kind of sensors are connected
how often / long the unit is connected to a PC
what environmental conditions the logger works in

WARNING!
The battery of EDAS logger IS NOT RECHARGEABLE. We recommend that
only original batteries of the type, model and brand stated before are used.
To fit the battery in its compartment proceed as follows:
Open the logger box by removing the 4 screws located under the
two black strips at the top and bottom of the box
Place the “D” battery in its compartment paying attention to the
correct polarity.
A green flashing LED will signal that now the unit is operative.
Note
If the unit is not connected to a PC, the green LED will stop flashing after some 10
minutes and the logger will enter a stand-by status.
WARNING!
Battery tension is continuously monitored via the Channel 8 of “eDAS”.
During logging operation, we advise to check this channel from time to
time, paying due attention to the tension values recorded.
Replace the battery if values lower than 3,45 Volt are noticed.
Additional “back-up” battery
A further battery is installed inside the unit. It is a 3V, 20mm diameter,
Lithium button cell “CR2032” to power the system clock.
Type Lithium cell
Brand PANASONIC
Model CR2032
The average expected operating life of such a cell is 4..5 years.
WARNING!
The CR2032 cell IS NOT RECHARGEABLE. We recommend that only original
batteries of the type, model and brand stated before are used.
Remove this cell only when it needs to be replaced so to prevent any risk of
losing recorded data.

Fig. 2 –eDAS PCB
Optional additional power supply systems
Sometimes - as in the case of a modem or a special-features type of
sensors being used - it may be requested to resort to some additional
power supply system. Of course, they need to be assessed and defined
each time according to the particular needs.
Typically, they will be made of a suitable box inside which a lead-acid
rechargeable battery, matched to a 220V charger (or, alternatively, a
photovoltaic panel) with necessary circuitry and wiring, are mounted.
In such a case the standard main battery will be automatically switched
off. Should the system detect any fault in the additional power system,
it will turn on again by itself.

eDAS logger fitted with Multiplexers
The implementation of one or more “multiplexers”offers the chance to
increase eDAS basic standard number of sensors that can be connected
(generally 8 or 16) and expand the logger possibilities at a low cost.
The following example shows how a 16-channel eDAS is expanded to
32 channels (in groups of 4) keeping it in the same standard box.
Adding a multiplexer to any eDAS logger entails that at least one of the
basic channels available has to be dedicated to the new device, by
configuring it according to the technical and electrical features of the
new sensors to be implemented into the system (see fig. 3).
This means that a multiplexer (or a group of
multiplexers) may be connected exclusively to
transducers of the same type (e.g. vibrating
wire gauges or current output transducers).
Consequently, for each different type of sensor
that you wish to add to your logger you will
need to get a further dedicated multiplexer (or a
group of multiplexers) that will relate to as
many input channels of eDAS logger (which will
be suitably configured).

eDAS Networking
Fig. 6 –eDAS networking
Figure 6 above illustrates a typical distribution of a number of eDAS
(NODES) networked on a 485 BUS connection. If needed, this BUS can
serve as well to carry the power supply from the additional Powerbox.
The maximum number of eDAS units in a network is 255 and the
distance from the first to the furthest node, provided that a suitable
supply source is available, can reach as far as 1 km.
In Fig. 6 you can also notice that it is possible to communicate with the
network either remotely via a GSM modem or locally via a
PC/Notebook

Modem
In order to connect remotely to eDAS you will need a GSM/GPRS
modem and a SIM card.
You will have to purchase and activate your SIM card (it is NOT
included in the standard equipment) ensuring to choose a M2M SIM
card for GSM/GPRS traffic.
Different options for SIM cards are available in the market and they
vary according to the various telephone operators in your country.
WARNING!
Before opting for one particular telephone company, we recommend
that you previously check that the GSM / GPRS signal in the area where
eDAS with modem has to be installed is sufficiently covered by the
operator of your choice.
Due to compatibility and efficiency matters, we suggest to include also
the modems in your order of a data logging system to BOVIAR s.r.l.
This way you can be sure that they are always correctly configured,
tested and ready to be connected to your new logger.
Boviar cannot guarantee that eDAS equipment works properly when
modem models of client’s choice are being used.

Modem connection
PC pole
Modem units are generally supplied with a charger and a RS232 cable
as standard equipment. If your PC has no serial port you will need to
get a USB-RS232 adaptor.
In this latter case the adaptor needs to be installed firstly (refer to the
product instructions).
GSM MODEM
1. Connect modem to your PC via cable
2. Insert aerial plug (standard accessory)
into modem socket
3. Insert your SIM card in its drive after
disabling its PIN code(*)
4. Connect the 220V mains adapter to the modem
(*) You can do this by inserting your SIM card in a portable phone and then proceed
to PIN code disabling. Now the card is ready to go into your modem.
The status LED will turn on to confirm it is now active:
1. Fast flashing (1/1s) = Searching for phone signal / No signal
2. Slow flashing (1/3s)= working OK
3. Steady light = phone connection on
eDAS pole
In this case, the modem unit is generally pre-mounted and pre-cabled
inside the Powerbox (or eDAS box) and it is already connected to power
supply.
Follow instruction as above or the ensuing operations.
