EMI-10L
Introduction
EMI-10L converter lets you convert a serial RS485 communications port on a bus Ethernet with TCP / IP.
The concepts and terms commonly used in the TCP / IP incorporated in this manual are:
Transmission Control Protocol (TCP)
 TCP is a connection-oriented protocol, it can transmit data to establish communication, negotiating a
connection between sender and recipient, and finally concludes with the closing of the connection. It
therefore has the capability to create, maintain and close a connection.
 TCP guarantees that data transmitted, if they reach their destination, they do so in order and only once: the
protocol into practice trying to simulate a direct physical connection of a stream of bytes through various
mechanisms, acknowledgment and retransmission on timeout.
 Each connection is associated with an active TCP socket opened by a process. TCP is responsible for
changing data between the active connections and related processes. For this, each connection between
two hosts is associated with a port number on each of the two hosts, which is an unsigned 16-bit
(1-65535), contained in the appropriate field header.
A TCP connection will be identified by IP addresses of two hosts and ports used on the two hosts.
EMI-10L Features
 The EMI-10L This is a bridge between MODBUS/TCPIP and Modbus /RTU. The serial port is connected to
a MODBUS/RTU device or a network of devices, while the Ethernet port is connected to the server/PC or
PLC systems. Commands are sent from the server via Ethernet, and the slave device gets these after
they've been converted.
 Serial-Over-IP: RS232 ports may have disappeared from your PC but serial interfaces continue to be
widespread in many industries such as security, automation and IT.
EMI-10L's serial-over-IP solutions marry the simplicity of serial communications with TCP/IP networking of
the Internet age. We supply external device, embedded Ethernet modules, and PC software that allow you
to quickly network-enable practically any serial device.

Common tasks
In any configuration window is the “Save” button that has the function to save the modified
parameters in the configuration of device. Always press this button otherwise the changes will be
lost.
The device has a default IP-address, if the device must be plugged into an existing network,
configure at first the IP address from the menu section NETWORK SETUP.
Configuration access
To access the configuration you must change the IP address of the PC. Follow the instructions at the bottom
of the following manual Troubleshooting section.
Open your browser (Internet Explorer, Firefox, etc. ..) and go at http://10.0.0.100/index.html
Please enter the correct Username and Password for administrator access and press Login button. It’s
possible to modify the Username and Password in the configuration of the device.
The menu, to access all the configuration pages, is available on the left side of the interface and has the
following structure:
Status:
Page summary of the status of the device.
Network Setup:
Serial COM Setup:
Modbus Setup:
User Management:
LAN settings.
RS485 (COM1) settings (baudrate, databits, parity, timeout).
Modbus protocol used for communication.
User settings (Device Name, Username, Password)..
Restore Default:
Reboot:
Log out:
Restart the device with the factory settings.
Restart the device with the current configuration.
To exit properly at the end of each session.
