The [[http:// | + | The Isolated RS-232 port is implemented using the ADM3252E Signal and Power isolated RS-232 transceiver. The [[adi>adm3252e|ADM3252E]] connects to UART3 of the ADSP-BF548 and is capable of functioning at data rates of up to 460kbit/s. Figure 1 below shows a circuit diagram of the implementation of the [[adi>adm3252e|ADM3252E]] on the //ez//LINX hardware. |
