Hi
I am trying to program propeller chip with the help of a RS 232 port. I have made the connect accoring tho the sche,matic given in[1]
but the also my PC is not detecting any Chip connected.
Do i have to connect MAX232 IC(level converter) or is the circuit given[1] is only required?

Also i have a USB to Serial converter cable can i just use this cable rather than using a prop plug? I have to give my project in 14 days and shipping of prop plug is not possible in the mean time.

The circuit in the PDF is all you need (nothing else.)
Re-check your wiring and then check it again, and make sure your serial (COM) port is good.
