I have got UART output from FT232 IC(USB to UART converter) from which further I want to use these signals for RS232 or RS485 or RS422 output which require different signals & have different circuits for each conversion.
So how can I switch UART signals to any one of the conversion circuit:
USB --------FT232-----s/w------ -a) RS23 / -b) RS485 / -c) RS422
i.e. if I have suppose 6 UART signals s/w should select these 6 at a time to either a), b) or c). Are such jumpers or dip switches available? Also is there any circuit using MAX485 or SN75176B which can interchangeably used as TTL to RS485 and RS422 converter?
