Makarand,
RxD and TxD connect to the Rx and Tx pins of the ADuC831. When you want to program the ADuC831, ground the PSEN pin, disconnect the RS-485 cable, connect the RS-232 cable to the computer and then power down and then power up. Then you will be able to run the WSD program to program the ADuC831. Jacob |
