#3 and #4. Homing using positive voltage level at Home Switch and index pulse message
When using method 3 or 4, the initial direction will depend on the current status of the
Home switch. The Home position depends on the index pulse to the left or right when the
Home switch status changes. If the initial position of the Homing is index pulse then it
must reverse direction of motion. Any further changes after the direction is reversed
depends on the current status of the Home switch.

#5 and #6. Homing using negative voltage level at Home Switch and index pulse message
When using method 5 or 6, the initial direction will depend on the current status of the
Home switch. The Home position depends on the index pulse to the left or right when the
Home switch status changes. If the initial position of the Homing is index pulse then it
must reverse direction of motion. Any further changes after the direction is reversed
depends on the current status of the Home switch.
