Raspberry-pi package does not work for HS01B-1 CB38M2A-1

[ckdarby]

Equipment

Control Panels: HS01B-1
Tested with control box: CB38M2A-1

Problem Summary

I tried using the raspberry-pi (Pi 4 Model B) for control panel: HS01B-1 with the control box CB38M2A-1. Unable to get any desk movement when issuing up or down. Height was not outputted; thus, it did not look like it was getting any bytes back on the serial either.

Additional Information

I was using a RJ45 to serial connector following the instructions. Here is the full Google doc I was using to keep track of everything.

README Issues

Pip serial package is missing in instructions
Pip RPi.GPIO package is missing in instructions

README has the wrong PIN 20 Raspberry BCM Pin documented?
Currently
12 (GPIO 18) PIN 20

I believe it should be
32 (GPIO 12) PIN 20

I believe this because the code references BCM and specifically says 12.
