Product Descriptions
E840-DTU (EC05-485)E is a small-sized 4G DTU developed by Chengdu Ebyte Electronic Technology Co., Ltd. using 4G CAT1 technology, available for Asia-Pacific region, Australia, New Zealand and other regions. It has small size, high speed and low
latency, low cost and easy to use. By simple configuration, it can realize the serial port device networking function ( two-way transparent transmission between the serial port device and the network server ). The product uses 2.54 spring crimp terminals
and supports installation on guide rails and positioning holes. It can also realize the serial port networking process, which is very convenient to integrate into Internet of Things projects.
The device with a small guide rail installation type is compact and easy to install. Through simple configuration, this device can be easily used to realize transparent two-way data transmission from the serial port to the network.
The device supports two links and MQTT protocol , making it easy to implement IoT applications.
