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
