Product Detail

GPRS-DTU is also called GPRS wireless data transmission terminal, which is a kind of embedded device which can realize RS232/485 and TCP/UDP/IP protocol conversion. It can meet the needs of users to carry out the wireless transmission service. It can provide the wireless interface for remote data communication. It can connect the embedded system to Internet. Data real-time transmission, industrial meter reading and remote measurement and control system for industrial control.

Q-7000 GPRS intelligent wireless data transmission terminal includes a complete PPP/TCP/UDP/IP/DNS protocol stack, the use of transparent transmission mode, users do not know the complexity of the TCP/IP network protocol, without changing the program to achieve the original serial wireless network connection, save your valuable time and existing investment. Its very low cost can improve the core competitiveness of your products; simple and flexible configuration and high reliability to meet the user any demanding application, is your ideal choice.

1.1 characteristics
(1) three line serial port (TXD/A+, RXD/B-, GND), support RS232 and RS485
(2) 1200bps~115200bps interface baud rate is adjusted by a user
(3) the exception handling capability of the full TCP/IP protocol stack is supported by a heartbeat, a chain check.
(4) boot automatically dial, automatic redial dropped
(5) support for the full TCP/UDP/IP/PPP protocol, support DNS dynamic domain name resolution
(6) support for the server model, but also support the client mode
(7) supporting a multi center mode, the data packets are available to three clients or servers at the same time
(8) industrial grade design, suitable for long-term continuous work, strong anti-interference ability
