The CX-4G is a compact and feature-rich GPRS transparent transmission module for mobile, China Unicom, Telecom 4G and mobile, China Unicom 3G and 2G network standards. With "transparent transmission" as the core of the function, it is highly easy to use, and users can easily and quickly integrate into their own systems. The software of this module is perfect, covering most common application scenarios. Users can realize transparent transmission of two-way data from serial port to network through simple setting. And support custom registration package, heartbeat package function, support 4 way Socket connection, and support transparent cloud access. With high speed and low latency.

CX-4G-L can be powered by lithium battery.

This module is compatible with our CM-GPRS module 2G products, users can directly replace them, thus achieving a significant increase in communication speed. On the hardware, we design a hardware watchdog to ensure the stability of the product for a long time.

Features:

■ 5 modulo 12 frequency: mobile, China Unicom, Telecom 4G high-speed access, while supporting mobile, China Unicom 3G and 2G access;

■ Based on embedded Linux system development, with high reliability;

■ Support RNDIS remote network driver interface, the computer can connect to the Internet via USB to access the device;
