1 INTRODUCTION
1.1 Introduction
DADO is a series of internet / MODBUS gateways, which communicate with the CloudEvolution internet portal via
Ethernet using the existing network infrastructure (on EVD2ETHB30), Ethernet or GP S (on EVD2ETHG30).
It has been designed to be as much firewall-friendly as possible and to require a low data traffic. Static IP address not
requested.
1.2 Basic knowledge needed to install a DADO
1.2.1 IP / Ethernet / Internet
A basic IP, Ethernet and Internet comprehension is required. You are supposed to know the meaning of IP network,
MAC address, DHCP, static address, router, hub, PAT/NAT, firewall and to be familiar with the network configuration of
your Windows PC.
1.2.2 Serial communication with devices and Modbus protocol
A basic S485 serial communication knowledge is required, functioning and wiring, Modbus protocol addressing and
communication parameters like baud rate, parity and stop bits, termination resistance, line polarization, daisy chain.
1.3 DADO identification
Each DADO has a serial number and a MAC address. These alphanumeric codes identify a DADO in the world,
regardless in which network it is located.
The serial number depends on the MAC address.
These codes can be found on the DADO side label.

3 DIMENSIONS AND INSTALLATION
3.1 DADO dimensions
The DADO dimensions, expressed in mm, are indicated in the following drawing.
3.2 DADO installation
DADO is made for DIN rail installation.
3.2.1 Inserting SD-Card
SD-Card must be inserted in the following way.

page 9 of 34
3.2.2 Inserting Sim Card (only for GPRS version)
Insert the SIM card in the device rear before the installation on the DIN rail, The device must be switched off (only on
EVD2ETHG30). It is recommended to remove the SIM card PIN before use in the device, to do this, insert the SIM card
inside a mobile phone and follow the documentation of the mobile phone to perform this operation.
3.2.3 Antenna mounting
Never use the device in areas where the operation of wireless equipment is prohibited. The location for the antenna
must guarantee the recommended radio electromagnetic limits (be at least 20 cm from persons and other antennas).
When the antenna is installed outdoors the lightning protection standard VDE V0185 must be complied with. The EMC
lightning protection zone concept must be observed. The device must be switched off during work on the antenna. It
can not be guaranteed that there will not be any harmful interference for other devices. In case of interferences install
the device or the antenna in another location (only for EVD2ETHG30).
3.3 ELECTRIC CONNECTION
The following drawing illustrates the DADO electric connection.

4 HOW IT WORKS
The following scheme illustrate the full system working.
(*) : An external Wi-Fi adapter can be used for wireless connection to a Wi-Fi Hot Spot.
4.1 Preliminary configuration
When configuring DADO for the first time, you need first to establish a TCP/IP connection via ETHE NET port.
Note: Download the DADO_CFG software from http://www.evco.it/assets/doc/DADO_IPCFG_setup.zip . To run the
software, a Windows PC is required.
