Hello everybody,

I try to download a programm from my laptop to HMI OP-320A but i can not . I have already check my cable and it is ok .The connection is the below
OP (9-pin port) PC (9-pin port)
RXD  2                  3   RXD
TXD  3                  2     TXD
GND 5                   5    gnd
7                            7

The problem is that i dont have 9-pin serial port  in my latop  and i use converter . 

I read that some   converter doesn't connect pin7 . What can i do about that?

Thank you
