Hi
I am trying to multiplex 4 RXD (RS232 level) signals from 4 different devices using IC C4066 to 8051 via MAX232.
Ch.1 --------
Ch 2 -------- IC 4066 ----- MAX 232 ---- 8051
Ch 3 --------
Ch 4 ---------
All 4 outputs of CD4066 are shorted.
Only ONE Channel is ENABLED at a TIME.
However, it appears that there is some channel crosstalk that is probably causing some problem.
Can anyone suggest how to eliminate this ?
