The GSM GPRS DTU ( Data Terminal unit or data-transfer unit) is special for wireless transparent data transmission by GSM GPRS Network.
More and more applications emerged with the rapid development of wireless Data Transmission services, such as Vending Machine management, PLC data logger, am meter, water meter, data collector, data sensor, etc. Thus, more and more devices need to be able to do wireless Data Transmission. With this background, King Pigeon Hi-Tech.Co., Ltd. develops its GSM GPRS DTU DTU-01.

GPRS DTU is integrated high performance ARM processor, embedded with TCP/ IP protocol stack, supports static IP address and dynamic domain name. Embedded with TCP/ UDP protocol, industrial design with standard RS232 port, it converts the data into GPRS network and transmits the data into the monitoring center. With the professional designing, GPRS DTU provides the plug and play, easy to use and maintenance features.

The GSM GPRS DTU with small size, which fits both embedded application and external peripheral equipment. The RS232 interface will offer easy data connection without any extra circuit control.

Also, a user friendly PC programmer is very useful for setup it by users.
