I've took the +5V of the 7805 and hooked it to the tx of the ttl (don't know if this was correct, no worries got myself 20 max232n ic's to practice <= already distroyed 2 :p)
The result isn't good, nothing changes: -8.46V on the tx and 0v on the rx for both the serial outputs. Is it possible that my setup is not correct for the max232n ic's, or am I missing something.
I've used this setup: http://www.dd-wrt.com/wiki/images/2/29/Max232_serial_mod_-_schematic.gif
Thnx for the reply
