Suggested update to Building an RS-485 Adapter Help Page

Fabulous project, and VERY much needed. Thanks so much for the work on this!

I am building my system, and after reading the help page on making up an RS-485 adapter, I have a suggested edit.

I think that the easiest way to build a suitable adapter is to buy two parts from e.g. Amazon.

1. Male RJ11 to 4 PIN AV screw terminal Adapter such as: https://a.co/coa2gwv

2. RS485 to USB Adapter, cable terminated such as: https://a.co/7T4iNq3

Then I think one can just connect the red and green wires from the cable end to the middle two screws on the RJ11 adapter, and you are done. Easy and cheap.

Looks like a great idea.

As it turns out, you need to connect the green and white wires to the outside two screws of the adapter, and make sure that the black and red wires do not short to each other. If you do that, works perfectly.
