DB9 RS 232 Pinouts and how to make up a usb to DB9 serial cable

I have a factory machine with a digital motor on it.  In order to configure it I need to connect via the DB9 Serial interface  that is attached to the drive. The documentation that came with the drive displays the pin assignments in a manner that  I am not familiar with.  I am also not sure how to make up a male usb to male  DB9 cable.

Pin assignments

Pin 1 -        IN 1+
Pin 2-         IN 2+
Pin 3-         OUT 1-, OUT 2-
Pin 4-         OUT 1+
Pin 5-         OUT 2+
Pin 6-         IN 1-
Pin 7-         IN 2-
Pin 8-         OUT 1-, OUT 2-
Pin 9-         OUT 1-, OUT 2-

I would appreciate any advice that I can get.

Thanks

Making the USB plug manually is not normally done (very picky). Standard USB Male to DB9 Male are readily available in most any electronics store.

Check Staples, Best Buy, Tiger Direct, Amazon or like and purchase the cable you need. They are very inexpensive.

For serial to USB, you don't go soldering things yourself, you'll blow up the system. Just buy a proper Serial>USB converter. A bigger name is: https://www.startech.com/eu/Cards-Adapters/Serial-Cards-Adapters/USB-to-RS232-Serial-Adapter-Cable~ICUSB232V2

There are electronics involved, it's not a 1 on 1 pin layout.
