Page 3: Chapter 1 Overview
Chapter 1 Overview 1.1 Introduction E95-DTU (400F20-485) is a cost-effective wireless data transmission radio station with multiple transmission methods. It works in the (410～510MHz) frequency band (default 433MHz). The radio provides a transparent RS485 interface, adopts a plastic shell, and is mounted on a guide rail. - Page 4 Use USB to RS-232 or other methods to connect the computer to the digital DTU. Start two serial port debugging assistants, select the serial port baud rate to be 9600bps (default), and the check method to be 8N1 to make serial port transparent transmission; Copyright ©2012–2018，Chengdu Ebyte Electronic Technology Co., Ltd...
