That's what I wasent shure to use max 232 our the fdti chip that's ok that I need the 5v to power the max 232 I will get the 5v from the external rs232 I will be using thanks

I followed the diagram GND’TX’RX’3.3V and want it to come out as a rs232 format I would rather just buy the chip but need to know what chip thanks also note i do not want to hook up to pc the router will be connected to a external device that uses rs232 protacol

trying to get the onboard rs232 to work but i think i need a ftdi chip for this i have solderd the pin to the corect pinouts but do go do i have to get a chip to convert to rs232
