1.1 Introduction KB3072 ZTU (Zigbee data Terminal Unit) is the use of high-reliability 8051 CPU cores and IEEE 802.15.4-compliant radio transceiver enhanced Zigbee module, he has a transmission distance, anti-interference ability, flexible networking, and other advantages. Zigbee-based data transmission network with a wide range of communication, transmission is stable, reliable, data relay and other characteristics, KB3072 ZTU and our existing product portfolio (KB3030) in unattended remote equipment monitoring, remote data acquisition, remote meter reading and remote scheduling and other areas has been widely used. Since this product is designed for industrial integration design, in terms of the temperature range, vibration, electromagnetic compatibility and interface diversity are uniquely designed to ensure job stability in harsh environments, data communications equipment to provide you high quality assurance. This product is suitable for one-to-multipoint, point-to-multi-point, multipoint, multipoint data transparent small data transfers. Widely used in industrial automation, remote meter reading, industrial monitoring, traffic management, meteorology, environmental protection, pipe network monitoring, financial, securities and other industries. 1.2 Features 1, standard industrial grade product, EMC anti-jamming design, ability to adapt to the environment; 2, independent research and development, the use of the 8051 classic, mature, stable; 3, the product comes with Watchdog, offers a variety of reset mechanism to software control, to achieve the perfect industrial security mechanism; 4, the operating frequency of the use of 2.4GHz, transmission is stable and reliable; 5, advanced and strict data communication protocol, comes with error correction and encryption. Data transfer is never loss; 6, powerful, supports three node types: the central node, relay route and terminal; 7, supports three transmission modes: broadcast, master-slave, point to point; 8, support a variety of ways to automatically group Network: one-to-multipoint, point-to-multi-point, multipoint, multipoint, and combined with our existing nine, there are other products can be set up huge system network transregional; 10, plug and play functionality : After configuring the parameters, the power to carry out ad hoc network, users only need a good butt serial device to achieve control center and two-way communication; 11, remotely modify ZTU parameters: This product supports remotely modify the parameters, the product is installed after If the need to adjust the parameters, simply use the software in the control terminal for remote configuration parameters can be; 12, support serial port baud rate: 2400bps ~ 115200bps, supports 7,8 data bits, one stop bit, odd parity , even parity, no parity; 13, the working temperature range: -40 ℃ ~ 85 ℃ -40 ℃ when the traffic is not affected
