This is a self-powered USB to Modbus RTU converter. It connects to a computer USB port via a USB-A cable with male connector at both sides. The Modbus RTU communication is connected via the RJ45 connector. We advise to use this converter in combination with Sentera 3SModbus configuration software. This combination facilitates monitoring and configuration of Sentera products. The Modbus RTU serial information is automatically converted to serial information on a USB virtual COM port in both transmitted and received communication.
