1. General description MDB-W is a bidirectional converter between a WiFi network and RS232 / RS485 serial channels . It therefore allows all devices equipped with a serial port to communicate with software or cards based on TCP/IP communication of a Wireless LAN. MDB-W also acts as an RS232 / RS485 converter. The integrated WiFi module allows the device to be configured easily and directly via the integrated web server. Galvanic isolation of the serial ports guarantees protection ensures isolation from the rest of the system. MDB-W is available in the following versions. Single product:...

2. Technical features GENERAL Access point or client mode ModBus TCP/ModBus RTU to RS232 conversion Bi-directional protocol conversions on all channels Serial communication speed up to Quick and easy configuration via integrated web ModBus TCP/ModBus RTU to RS485 conversion Default parameters: IP: 192.168.1.101 DHCP disabled 9600 bps IP41 plastic case for DIN rail Relative humidity: from 0 to 80% without condensation Storage temperature: -40°C ÷ 60°C POWER SUPPLY AND CONSUMPTION Power supply 10-30 VDC Average consumption 30mA SAFETY INFORMATION - The use of radio devices may be...

3. Quick Start 3.1 Power supply Connect MDB-W to a 10-30 VDC power supply unit (Fig.1). N.B. MDB-W is reverse polarity protected, but polarity must be observed for correct operation. Fig. 1 Power supply connection 3.2 RS232 & RS485 serials MDB-W can bridge both an RS485 and an RS232 serial port. Terminals for connecting the serial ports are as in Fig.2. Fig. 2 RS232 and RS485 serial 3.3 Ethernet MDB-W has an Ethernet RJ-45 connector, but at the moment it is not used. Fig. 3 Ethernet connector 3.4 Access and configuration MDB-W has an integrated WEB server, therefore you can configure it...

These the steps to follow: 1. Connect from your PC to MDB-W Wi-Fi. Each MDB-W provides its own network with the name MDBW, e.g. if the serial number is 002100100 the available network will be MDBW002100100 To connect to the network, enter the password, which by default is: 123456789. Once connected, open your web browser and type in 192.168.4.1 The first screen (Fig. 4) is the authentication page using username and password. Default values are: Username: After logging in, you have access to the configuration web pages described in detail in chapter 4. WiFi – RS232 connection scheme

WiFi – RS485 connection scheme By reading the QR code below you will access the MDB-W WEB page: 4. Programming Main menu 4.1 Communications The communications menu allows you to set all communication parameters for all channels. In detail, there are the following sections: • RS485: for RS485 serial channel parameters (Communication speed, number of bits, stop bits and parity) • RS232: for RS232 serial channel parameters (Communication speed, number of bits, stop bits and parity) • ModBus Server: the port used by the ModBus server (MDB-W) which, together with the IP address, forms the socket...

Fig.4.1 Communications mode selection screen 4.2 Network This allows parameters of the LAN network to which MDB-W is connected to be entered, in order to make it communicate with servers for sending data. In detail, these are the parameters to be configured: - DHCP: allows you to determine whether the network DHCP server should be used to assign the IP address or not - IP address: the static IP address assigned to MDB-W IP network mask: the subnet mask or netmask is used to determine the range of IP addresses within a subnet - IP gateway: IP address of the reference gateway HTTP server...

4.3 WiFi This screen defines the Wi-Fi network to which MDB-W will connect as a client. The exact name of the network must be entered in the "SSID Name" field. A button is available to scan and choose the exact network from a list. "Password" is the password for accessing the network. Always remember to press the Save button before exiting the screen.

4.4 Password Set the password to access to the MDB-W configuration page. Fig. 4.4 Changing access password screen 4.5 Info The info menu displays hardware and software information about the device. Fig. 4.5 General information screen The Update firmware button allows you to update the firmware on your device. We recommend that you always check at https://www.4next.eu/prodotto/convertitore-wifiseriale/ to see if the firmware is up to date.

5. Return and repair Return for repair or replacement must be authorised in advance by requesting an RMA number. Then send by e-mail to support@4next.eu or to your dealer/reseller a form containing the following information: • Company name and customer data (address, telephone, fax, e-mail) Contact person Product data P/N and S/N located on the back of each product or on the original box 4neXt will send the RMA number with which the customer can send the material for repair.
