(IT 21_03_16 rev. 2 AM) Enhanced Data Acquisition System 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.

Batteries and Power supply additional devices 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.

When using batteries:  Recharge them exclusively with the charger supplied with the standard equipment. NEVER USE CHARGERS OF OTHER MAKES.  Do not heat or throw batteries into fire or put them close to heat sources.

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.

Page 15: Edas Networking
(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.
Page 16: Modem
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.
