| Abstract: | This paper proposed a decoder and transformer based on RS485 transfer protocol, which is used in themonitoring device. The equipment is used to control the camera and rotational station. It is widely used in themonitoring system, which convert the controlling protocol to signal. RS485 protocol is adapted in transmitting ofinformation. The effective transmit distance is about lOOOmeters and the processing of information depends onmicrocontroller. |
