1、 What is DTU?
DTU (data transfer unit), the full name of data transmission unit, is a wireless terminal device specially used to convert serial port data into IP data or convert IP data into serial port data for transmission through wireless communication network.
DTU is simply an industrial level wireless transmission equipment, which is mainly used for wireless data in various industries. The device transmits the terminal data to the server through the serial port or network port through the wireless network.
DTU wireless transmission: mainly through the operator network, that is, mobile, telecom and China Unicom. That is to insert a SIM card (mobile phone card) to realize wireless transmission That is, mobile wireless internet access is almost the same.
2、 Are DTU features significant?
1) Internal integration of TCP / IP protocol stack;
2) Provide bidirectional conversion function of serial port data;
3) Support automatic heartbeat and stay online forever;
4) Support parameter configuration and permanent saving;
5) Support user serial port parameter setting.
3、 DTU price?
DTU is generally not publicly priced and is fake. You can talk to me about it Therefore, you can't find it on the Internet. GPRS DTU must also have some understanding I can't give a clear explanation on this price.
