1 Product Overview
1.1. Introduction
E840-TTL-4G02 is developed for serial port devices and network servers
to transmit data to each other through a network.It is a
LTE-FDD/LTE-TDD/WCDMA/TD-SCDMA/CDMA/GSM wireless
communication data transmission modem with diversity receiving function,
supporting LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+, HSDPA, HSUPA,
WCDMA, TD-SCDMA, CDMA, EDGE and GPRS network data connections,
through simple AT commands Settings, you can easily use this product to
achieve two-way data transparent transmission from serial to network.
The module with 2.0 mm pin header is good for embedded development
by a wide voltage of 5.0V to 20.0V. Support 4G card, RS485 and RS232.
With circuits electrical isolation scheme for anti-interference ability, it can be used in environments with strong
electromagnetic interference, such as power industry. This manual is a quick introduction to the modem E840-TTL-4G02.
It is the easiest hardware environment to test the E840-TTL-4G02 network transmission function, that is, to realize data
being transmitted in both directions between the serial device (here, the computer) and the network server.
1.2. Features
◼Almost meet all M2M application demands;
◼Support data transparent transmission, support TCP, UDP network protocol, support heartbeat package,
registration package function；
◼Support two-way serial transmission from device to network server for 230400 serial port baud rate and
below,;
◼Support serial port large cache function, the serial port data can be cached locally before the server is
established.；
◼Support SMS sending and receiving, SMS remote query / configuration device parameters；
◼Support multiple Socket links to send and receive at the same time；
◼Support Modbus RTU and Modbus TCP to automatically convert each other；
◼LTE-FDD：Max downstream rate of 150Mbps， Max upstream rate of 50Mbps，LTE-TDD：Max downstream
rate of 130Mbps，Max upstream rate of 35Mbps；
◼With software/hardware double watchdog design, the system is stable, will never crash.
