Media Converter LAN-RS485

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 in TCP Client mode.
Once connected, data from the RS485 port of the first module is transmitted to the other and vice versa.
Only a single Client module can be connected to a Server module.
Connection can be established over the Internet or a local network.
In this mode, it does not matter which module will be connected to the MASTER and which to the SLAVE device.

Example configuration:

Client UDP → Server UDP

All data that is received by the RS485 port on the client module is sent to the server module and vice versa. By using UDP / IP (connectionless protocol), the user can achieve higher data throughput. Server module can only send data to one client module. Connection can be established over the Internet or a local network.
It is important that the Master device is connected to Media Converter which operates in UDP Client mode. This is due to the fact that the Client sets the network parameters by sending the first data packet to the server. Otherwise, the server (if it does not receive any package) will send data to the broadcast address.

Example configuration:

UDP Multicast connection

All incoming data to 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 a local network.
