The converter allows you to connect devices with RS485 interface to a PC via LAN TCP / IP. Management and configuration is done via the built in website. The device has firmware can be updated via TFTP. Ideal to use with the MODBUS protocol.

Connection modes

Client TCP → Server TCP

The module which operates in TCP Server mode waits for a connection from the module operating as a TCP Client mode.

Once connected, data from the RS485 port of the first module are transmitted to the other and vice versa.

To the Server module can be connected  only one Client module.

Connection can be established over internet or local network.

In this mode, it does not matter which module will be connected to the MASTER and which to the SLAVE device

Example confituration

Client UDP → Server UDP

All data that is received on the RS485 port on the client module is sent to the server module and vice versa. By using UDP / IP (connectionless protocol) user can achieve higher data throughput. Server module can only send data to one client module. Connection can be established over internet or local network.

It is important that the Master device is connected to Media Converter which operates in UDP Client mode (as in the picture below). This is due to the fact that the Client by sending the first data packet to the server sets the network parameters to send data through the server. Otherwise, the server (when it did not receive any package) will send data to the broadcast address.

Example confituration

The UDP Multicast connection

All incoming data on the RS485 port is sent to the multicast address on the network and gets to all the modules operating in multicast mode. Such connection may be carried out only in the local network.

The connection UDP / Multicast mode:
