Feature; Product Overview; Introduction; Parameter - Ebyte E840-TTL-NB03 User Manual

Chengdu Ebyte Electronic Technology Co., Ltd.
E840-TTL-NB03 is developed for serial port devices and network servers to transmit data
through the network. It supports B8 frequency band. It can be easily set up with simple AT
commands. It can be used to realize serial-to-network two-way data transparency transmission. This
chapter is a quick introduction to the E840-TTL-NB03 product. It is the easiest hardware
environment to test the E840-TTL-NB03 network transmission function, that is, realize the two-way
transparent transmission of data from the serial device (the computer) to the network server.

Feature

It meets almost all M2M application needs；

Support data transparent transmission, support TCP/UDP network protocol, and heartbeat packet and

registration package function can be customized；
Serial port caching is supported. The serial port data can be cached locally before the server is connected；

The maximum downlink rate of NB data is 85.6 kbps, and the maximum uplink rate is 85.6 kbps；

Supports protocols such as TCP/UDP, encoding formats CS-1, CS-2, CS-3, and CS-4

1. Product overview

1.1 Introduction

E840-TTL-NB03 is a NB data transmission module developed by Ebyte. The software is fully functional and covers
most common application scenarios. Users can realize two-way data transparency from serial port to network server
through simple setup transmission.
The module uses 2.0mm pin headers to facilitate customer device integration, using 5V ~ 20V voltage supply.
Support mobile NB card, communication and LED indication with compatible level, default 3.3V can be applied to 5V
level, with anti-interference ability, can be used in some environments with strong electromagnetic interference, such as
some power industry.
