E840-DTU(NB-02) can realize the communication between serial port device and network server via NB network. With simple AT

command, users can easily use this product to achieve bidirectional transparent data transmission from the serial port to the network.

This manual focuses on the brief introduction of E840-DTU(NB-02). It explains how to make the simplest hardware environment and

test the transparent transmission of E840-DTU(NB-02). The transparent transmission is between UART devices（referring to PC） and net

sever (replaced by TCP testing tools).

Features

Based on NB-IOT communication standard, it can realize more 20dbi gain than GSM.

Support Single Tone, Sub-carrier 15kHz and 3.75kHz：21.25kbps (Downward)

Support multiple network protocol, such as CoAP，UDP，IPv4 ,LwM2M etc.

Support 3GPP TS 27.007 V14.3.0 (2017-03) and Quectel intensified AT command.

Support 8-28V wide voltage power supply, and adopt DC and terminal as the two power supply methods.

RS485 circuit use the electrical isolation, lightning protection and surge protection scheme, it has anti-interference ability.

1. Introduction

1.1 Brief Introduction

E840-DTU(NB-02) is a NB-IoT DTU produced by Ebyte. It features a certain scope of applications which cover most common

application scenarios. The user can realize bidirectional transparent data transmission from the serial port to the network server by simple

setting.

E840-DTU (NB-02) supports DC and RS485 terminal power supply. Its voltage ranges from 8.0 to 28.0V. 5.0V works too. RS232 and

RS485 apply electric isolation which enables anti-interference. It is applicable in some environment with strong electromagnetic

interference like power sector.

2.1 Device Preparation

E840-DTU(NB-02)

12V Power adaptor

NB-IoT DTU E840-DTU（NB-02）User Manual

USB to RS485 adaptor or USB to RS232 adaptor

NB-IoT sucker antenna

Please get UART, SIM card, sucker antenna and etc. ready according to the recommended circuit before test.

2.2 Data Transmitting Test

Software is needed for data transmitting test:

Xcom is applied here for the test and you can download it at our website. Users can also apply other test tools that are available.

2.2.1 Test Steps:

1. Insert the SIM card into E840-DTU(NB-02) and connect it to the computer according to the above mentioned methods. Open

the Xcom, set the parameters of corresponding UART NO. and baud rate(only 9600 is available)and turn on the UART.

2. When powered on with the power adaptor provided by us, POWER indicator on and NET indicator blinking shows that the

transceiver is ready.

3. Wait for 3s-5s to use the serial AT command to access the module.

4. Normal network process

Neul // Waiting 3s after module is powered on

AT+CFUN=1 // configure cfun，“1” means open all the function of module

AT+CIMI //Inquire IMSI——Delay 3s to inquire to ensure the module can recognize the card.

460012345678966

AT+NBAND?

+NBAND:5 // Read the current frequency, “5” means 850MHz;

AT+NCDP=139.199.157.166,2017//configure CDP server

AT+NCDP? //read the current CDP server

NB-IoT DTU E840-DTU（NB-02）User Manual

+NCDP:139.199.157.166,2017

AT+CGATT=1 //register network

AT+CSQ //read the current signal intensity +CSQ:21,99 ；

AT+CGATT? // Inquire the network status-it takes times for module to join network. Query within 30s until it is 1, “1”

means connection already.

+CGATT:1

AT+CEREG? //Inquire network registration status, “1” means success;

+CEREG:0,1

Note: Before the module joining the network, the IMSI of sim must be registered in the core network, or it cannot register the

network.
