Description

USR-GM3 UART to GSM/GPRS Module TTL to GPRS Bi-directional Transmission

Introduction:
USR-GM3 is highly-integrated UART to GSM/GPRS module, Users can easily make communication with it among serial device,cellphone and network device.USR-GM3 is an embedded GSM module. It is designed for embedded system, and it is so small and convenient that you can integrate it to your system easily.

Features
- Small and completed function GPRS DTU, transmission between serial and GPRS
- Support GSM850/900,DCS1800/1900
- Support GSM/GPRS/EDGE and 2G/3G/4G,2G traffic
- Support 2 sockets, Support TCP and UDP
- 4KB cache for each of sockets, user can choose to cache data or not
- Support register package and heart beat package
- Support setting parameters via SMS message
- Support 4 work modes: SMS message transmission mode, network transmission mode and HTTPD mode
- Support basic and extend AT command sets
- Support similar RFC2217
- Support flow control: RTS/CTS
- Support RS485

Functions
- Built-in Antenna Interface
- Httpd Client(Click to learn the function of Httpd Client);
- Two Network Links : GM3 can build TCP link with two target servers and send the same data;
- SMS Transmission : TTL can directly output SMS content;
- SMS Configuration : telephone sends SMS to configure GM3;
- Send SMS : apply to application of SMS alarm;
- Hardware Flow Control : RTS/CTS;
- Register Package Mechanism : convenient for server to identify device;
- Heartbeat Package Mechanism : guarantee normal network connection;
