Each of these will be described in more detail below.
Motor Control Wiring
Motor Driver Board
The Left/Right wires go from the Dome Controller board to the Motor Driver
board. The wires may be connected in parallel with the manual switch at the
Motor Driver board.
A ground wire must also be connected between the boards. This provides a
return path for the control lines. This wire can be connected to any of the
terminals marked GND.
Note that, if for some reason the dome rotates in the wrong direction, the Left
and Right wires can be swapped.
Magnetic Home Sensor Wiring
The Home Position sensor is a simple magnetic reed switch, commonly used in
home burglar alarms. The switch is open when the magnet is not present, and
closed when it is present.
The magnet and sensor must be placed adjacent to each other, such that the
magnet rotates with the dome, and the sensor remains stationary. The switch will
close only when the dome is in a position where the magnet is directly adjacent
to the sensor. This allows the Dome Controller to reposition the dome to a known
position prior to operation, so that it knows the azimuth of the dome.
