Look guys,
My schematic use 2 transistor and 3 Rs per tx line. You dont need any other ic as converter or similar.
I am mounting 4 PIC forming a network, 1 master and 13 slaves. Tx from master...

Mr Demon,


I definitely solve this.
You will need a couple of transistor per each Tx output and 3 resistor.


As you said, if you disable the usart, also Rx line will be disable.
If you...

Hi,
I am assembling this circuit. 1 Week ago i am suffering of the same situation that you have.
I am conecting 5 PIC 16F690, 1 as master (Tx conected to 4 Rx) and 4 slaves (all tx in parallel...
