1.1 Brief Introduction
KB3200 GPRS RTU(Remote Terminal Unit) is the use of high-reliability processors and industrial grade GPRS wireless data transmission module, embedded microcontroller technology, GPRS wireless communication technology and engineering measurement and control technology, high reliability, high stability, functionality, wide range of applications, is one of the new generation of remote communication control terminal widely used for telemetry, remote control, wireless data transmission in
KB3200 GPRS RTU integrates analog, digital signal acquisition, optocoupler outputs and GPRS wireless data transmission in one, built-in Modbus-RTU protocol, direct access to a standard analog transmitter output signal (4 ~ 20mA), level signal, pulse signal (custom), connect and control a variety of Modbus-RTU protocol for industrial instrumentation.
KB3200 GPRS RTU is used in electric power automatic system, industry monitoring, traffic management, atmosphere, pro-environment, pipe network monitoring, finance, securities departments and so on. Consider the networking request from different application scope, achieve Virtual data private network in network structure. It is applicable to data remote acquisition and control of the Center to multi-points, multi-points scatter Center to multi-points, multi-points scatter.

1.3 Safe Use
KB3200 GPRS RTU Completely complied with national radio product safety technical regulations.
Warm Tip: You must not touch the antenna with your hands or body. During 15 seconds after KB3030-RO DTU started, Please keep away from the antenna. If the antenna is damaged, you must replace it in time, assorted and qualified cable and antenna.
1.4 EMI
Now most electric device all has electromagnetic pulse hardening, but some old device may have no, under RF power radiation, it may go wrong. When you use KB3030-RO GPRS DTU, please check the device nearby have electromagnetic pulse hardening or not.
