Hi Geeks,
I want to know the RIGHT way to join (parallel) four seperate serial data lines to the single USART RX pin on a PIC.
Only one serial line will be enabled at a time (coming from RS422 line receiver chips).
The easiest solution is to just S/C the four signal lines but is this correct?
Can I use schottky diodes on each serial line or should I just use a 4 input OR gate instead?
Is there a better method that I haven't thought of?
Thanks.
