Product Descriptions

E840-DTU (EA01) is an NB-IOT radio product, which has complete software functions and covers the vast majority of conventional application scenarios. Users can achieve bidirectional data transparent transmission from serial port to network server through simple settings.

E840-DTU (EA01) is a product developed for the mutual transmission of data between serial devices and network servers through NB networks. With simple AT commands, this product can be easily used to achieve bidirectional transparent data transmission from serial ports to networks.

The radio is powered by a DC power socket or RS485 terminal in the power supply section, using a wide voltage range of 5V to 36V and supporting 5.0V power supply. RS485 and RS232 circuits use an electrical isolation scheme, which has anti-interference capability and can adapt to use in environments with strong electromagnetic interference, such as some power industries.

Product Features

• Support transparent data transmission and TCP/UDP transparent transmission; Support heartbeat package and registration package functions;

• Supports protocols such as TCP, UDP, MQTT, COAP, LwM2M, etc;

• Supports Telecom Cloud CTWING, Huawei Cloud OceanConnect, China Unicom Cloud, China Mobile onenet Cloud Platform, Alibaba Cloud, Baidu Cloud;

• Support simultaneous transmission and reception of two Socket links;

• Supports Modbus RTU/TCP conversion

• Supports a wide voltage supply of 5-36V, using two power supply methods: DC power socket and terminal;

• The RS485 circuit uses electrical isolation, lightning protection, and surge protection schemes, and has anti-interference capabilities;
