Hi All,
Directly i want to ask my doubts :
1. Is schematic attached is correct ? - this board to communication over 3 meter distance so there is two transceiver is used at both board . One board connection i attached. could any body confirm if it is correct ?
MCU1-> TX1 -> DIN1 -> DOUT1 -> RIN1 -> ROUT1 -> RX2 -> MCU2
MCU1 <-RX1 <- ROUT1 <- RIN1 <- DOUT1<- DIN1 <- TX2 <- MCU2
2. Can i add 100ohm series resistor at MCU end in both lines ?
3. Can i add RC filter after max3232 transceiver i.e. 100 ohm with 100nf for filtering purpose ?
4. Can i put ESD diode after at RS232 end as shown and if yes what is the value.
5. How to interperate voltage level of RS 232 for driver and receiver ?
Thanks
