■ USR-TCP232-304 module is used to realize two-way transparent transmission of data from serial port to Ethernet port. Users do not need to care about specific details, and the protocol conversion is completed inside the module. The serial port side is the RS485 level data, and the Ethernet port side is the network data packet. The work details can be specified through simple settings. The parameters can be set through the built-in web page or through the setting software, and the one-time setting is permanently saved.
