 SCADA_RTU System 		     SCADA system can be used in the unattended room for house keeping. The RTU is a unit for monitoring remote terminal. It collects the switch values and 4-20ma analog value into RTU, then sending to the remote central station.
  RTU signals can be transmitted by either E1 channel or fiber optic. Both SCADA and optical transmission are the business of Hengguang.
