Gprs remote controller is a wireless date transmission terminal based on GPRS network, provides transparent date channel, can facilitate the realization of the remote, wireless and network communication. Make it easy for your device with Internet to connect by wireless. GT81 has a wide range of network coverage (it can be used anywhere you can use mobile phones), flexible and fast networking (installation can be used), low operation cost (billing according to the flow) etc.
Large buffer design(serial port to send and receive, built-in 8 KB of data cache),using dynamic partitioning technology to improve system operation speed;
The length of single packet data can be set up, the biggest support for 1024Bytes, suitable for continuous transmission of data;
Uses Quectel industrial GPRS module, embedded TCP/IP protocol stack;
Wide voltage power supply: 7~36V;
Has the function of the power off, convenient user to control;
Transparent data transmission, users don’t need to understand the complex TCP/IP, PPP protocol;
Supports dynamic domain, fixed IP and fixed domain communication mode;
Supports backup data center;
Supports virtual private network(APN);
Remote wake-up: supports SMS and telephone;
Supports auto-connection while disconnect;
Support local, remote graphical interface parameter configuration and maintenance;
Supports SMS parameter configuration and maintenance;
With three kinds of interface: RS232, RS485 and TTL;
Supports 7bit, 8bit, 9bit data transmission;
Support parity, Mark, space check;
Multiple hardware and software reliability design, compound watchdog technology, make the equipment safe operation
