G03 Ethernet 10/100MB 2xRS232/RS485 MODBUS TCP/RTU/ASCII Gateway

Modbus Gateway G03 description

The Modbus Gateway G03 enables data transmission between LAN hosts and serial devices by converting Modbus protocols (Modbus TCP, Modbus RTU/ASCII). It is intended to be used in networks but not only. Apart from extending the capabilities of industrial devices, they can be also adapted to the user’s requirements and needs. The G03 offers two transmission modes: Gateway and Router. In Gateway mode, the port is used for communication with Slave devices, while in Router mode, it communicates with Master devices. Different modes can be set independently on each port. The G03 device features two RS232/RS485 ports (user should use only RS232 or only RS485 interface of one port as they occupy the same internal bus of the device), RJ45 Ethernet socket, and supports data transmission speeds up to 115200 bps. It is based on an ESP32 microcontroller, operates on a 12–30 VDC power supply, and stands out for its low power consumption of less than 1W.
