Hello
I have faced with the problem of communication my 1400 m98 bw3.2 robot via rs232 port
So, I need to connect the robot to my PC with USB port
I bought rs232 - USB adapter but as I understand robot rs232 using 10v for the signal and PC's USB using 5v
So my question
How did you connect usb pc with rs232 (10v - 5v adapter?)
Or just using rs422 port?
Thank you!

What do you want to achieve ?
I would have to double check my history books, but we did use 422 <> 232 media converters back in the day, but I could have sworn we used normal 232 without converters too, but that could have been S4's (M94)
The console should be normal 232 though

All the USB-to-RS-232 converters I've used step up the voltage to the proper value.
