NOTICE!
When the camera's RS-485 port is connected to a MIC-BP3 Biphase convertor, the camera's TRX+ should be connected to the convertor's RxB, and TRX- should be connected to RxA. The camera's baud rate should be set to 9600, and the protocol should be set to Bosch OSRD. Also make sure that the camera ID is configured correctly. For further details on setting up the MIC-BP3, please refer to the separate MIC-BP3 Bi-Phase Converter Card Installation and Operation Manual.
