ALL computer ports are 5Volts  NOT 9volt

So I was misinformed. That's strange. I used to trust that guy. He is pro.

most computer PSU's are 12VDC (yellow wires) or 5VDC .

That 5VDC is what lets most single lithium cells recharge. (3.5VDC).

The 12VDC is what runs the accessories, fans, hard disc's, DVD burners.....

That TTL converter was just an experiment because several persons insisted it was needed.
It is not.

mizlplix SUCCESS!   Tanks alot man, you saved me a lot of money! :mE>: :uy<:
Bought simple RS232 socket at radio market for 0,5 dollars and it works! :EL^:
Thanks again!

Hello everyone,

Is there any information on the AC50's motor parameters? I've been seraching them up but, so far, I've been unsuccesful. I need the stator and rotor resistances, as well as their inductances, or at least, a fair estimate of their values. Does anyone have measured paramaterers this already? Any help would be greatly appreciated!

Thanks,
Jorge

There is no rotor resistances  :Ah#: there is no winding in a ac motor, rotor.
The resistances in the stator winding is only 2-3 ohms, the lower the voltage
the lower the resistances. For instance, what is the resistance of 60 foot piece
of 18 gauge copper wire, that is roughly the length of one coil set, one phase.

Make sense ??
