1. Descrizione Generale
It therefore allows all devices equipped with a serial
port to communicate with software or cards on
Ethernet communication.
MDB-E also acts as an RS232 / RS485 converter.
Thanks to the NFC (Near Field Communication)
interface, the configuration is very simple and
practical. A dedicated APP allows you to read,
modify and set all device parameters.
The galvanic isolation of the serial ports guarantees
protection for all connected devices and it
guarantees isolation from the rest of the system.
MDB-E works independently from the protocol by
connecting all the protocols based on TCP / IP with the serial ones in a
completely transparent way. This simplifies the configuration and installation of
the bridge.
This Ethernet - Serial converter has been specially designed for industrial
environments, equipped with 10-30Vdc extended range power supply.
It does not need any additional software for configuration.
MDB-E is a bidirectional converter between the Ethernet communication channel
and the RS232 and RS485 serial channels.

•The use of radio devices may be inappropriate near electronic equipment.
•Do not install the MDB-E near medical devices such as pacemakers or hearing aids. MDB-E can
interfere with the proper functioning of these devices.
•MDB-E must not be used on board aircraft.
•Do not install MDB-E near oil stations, fuel depots, chemical plants, explosion sites as MDB-E can
disturb the operation of technical equipment.
•MDB-E can generate interference if used near television, radio or personal computers.
•In order to avoid possible damage, we recommend the use of accessories tested and specified as
compatible with MDB-E.

3. Quick Start
3.1 Power supply
Connect MDB-E to a 10-30 VDC power supply (Fig.1).
N.B. MDB-E is protected with polarity inversion but for correct operation the
polarity must be respected.
3.2 RS232 & RS485 serials
MDB-E allows you to bridge both an RS485 and an RS232
serial. The terminals for the connections of the serial ports
are as in Fig. 2.
3.3 Ethernet
For connection to the Ethernet network, the MDB-E is equipped with the RJ45 connector
on the front panel (Fig. 3). When connected to an Ethernet network, the status LED
turns green. When there is communication, the green LED flashes.
3.4 Access and configuration
MDB-E is equipped with an integrated WEB server, therefore it can be configured using
a standard browser. To access the configuration pages, type the IP address of MDB-E
from the browser of your PC, tablet or smart phone.
The device from which you connect must be within the same network as MDB-E (Par.
2.1).

3.5 Network IP address
The default IP address of MDB-E is
192.168.1.101.
If you network is of the same IP class: 192.168.1
..., go to paragraph 2.3, otherwise follow the
instructions from point 2.2 to set the correct IP
address.
If your network To identify the IP class of your network, run the IPCONFIG command
from the command prompt. In Fig.4 on the side, the IP address of the PC is 192.168.1.5.
It belongs to the same class / network as MDB-E, as the first 3 numbers (192, 168 and
1) are the same.
It is therefore possible to reach MDB-E from the PC browser.
If the network is NOT of the 192.168.1 class, you can proceed in 2 ways:
1. Set MDB-E to work in DHCP (see paragraph 2.2);
2. Set a valid IP on the MDB-E
3.6 Configuration and settings
MDB-E is equipped with an NFC interface that allows the configuration of all system
parameters via the iBridge APP.
3.7 Login and authentication
Once the IP address has been defined, type it on the
browser. It will then be possible to access the MDB-E
configuration and consultation pages.
The first screen (Fig. 5) is the username and password
authentication page.
The default values are:
Username: admin
Password: admin

Main menu
5.1 Bridge
After logging in, you access the configuration menu. The first screen, the
one shown in the figure below, allows you to choose the working mode
of the Bridge.
The options are:
•Ethernet –serial: MDB-E acts as a converter between the Ethernet
channel and both serial channels simultaneously. This means that devices
on RS485 or a device on RS232 can be connected indiscriminately. Not
at the same time.
•Radio - Ethernet, serial: In this configuration, the radio communication
module is activated if present. It is necessary to have a pair of devices
to ensure that they transmit the received packets to each other. The
device equipped with the radio module is identified as NetLink.
•Serial-Serial: In this mode the protocol conversion is performed
between the RS232 communication channel and the RS485 channel.

11
5.2 Communications
The communications menu allows you to set all the communication parameters
for the various channels. In detail there are the following sections:
•RS485: for the parameters of the RS485 serial channel (communication
speed, number of bits, stop bits and parity).
•RS232: for the parameters of the RS232 serial channel (communication
speed, number of bits, stop bits and parity).
•ModBus Serve: the port used by the ModBus server (MDB-E) which,
combined with the IP address, forms the socket on which MDB-E listens
to receive ModBus TCP packets.
•ModBus Client: an additional ModBus TCP client that can be updated
with the transferred data.
•Radio: this section allows you to set the parameters of the two NetLinks
that exchange information via radio.
o The transmission frequency must be the same.
o Local address: it is the address of the NetLink that is being
configured.
o Remote address: it is the address of the NetLink that will receive
commands via radio.

5.3 Network
It allows you to enter the parameters of the Ethernet network to which MDB-E is
connected in order to communicate with the servers for sending data. These are in detail
the parameters to be configured:
•DHCP: it allows you to determine whether you should use the network DHCP server
to assign the IP address or not;
•IP address: the static IP address assigned to MDB-E. If DHCP is enabled or Dip-
Switch 2 is set to ON, the IP is not the one displayed;
•IP network mask: the subnet mask or netmask allows you to determine the range
of IP addresses within a subnet;
•IP gateway: IP address of the reference gateway;
•HTTP server port: http server port when different from standard 80 or 8080.
