The configuration of the physical serial port 3 mode is done by a set of 4 dip switches that are located on the bottom face from the unit. The settings of the switches are shown in the table below (note: when you look the bottom face from the eWON® with its front face at your right hand, then switch 1 is the leftmost switch on the dip switch panel that matches serial port 3: this dip switch panel stands at the right part from the eWON®’s bottom face, below the serial port 3 connector, which stands at the bottom right from the eWON®’s front face, just below serial port 2).
