The Shutter Closed sensors are simple magnetic reed switches, 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 so that they are adjacent when the
shutter is closed. This provides a positive confirmation that the shutter is in the
closed position. A sensor is provided for both the upper and lower shutters.
One sensor should be connected between the REED 1 and GND terminals. The
other sensor should be connected between REED 2 and GND. It does not matter
which sensor goes to which REED terminal; both must be closed for the Dome
Controller to report back "closed" to the PC.

Power Supply Wiring
The controller card requires +12VDC for operation. Please be sure to observe
the correct polarity when connecting the power. The board draws 75 mA at 12V.
It can operate down to about +9VDC.
The standard 12V DC battery will provide sufficient power for the motor and the
controller board. If you use an alternative power source, make sure it can handle
the current surge when the motor starts working; if the voltage drops too much it
may cause the controller board to reset.
It is recommended that a switch be added to the battery leads to preserve battery
life when the unit is not operating. This switch can be mounted onto the side of
the fiberglass motor enclosure.

DIP Switch
Switch 4 switches between Channel A and Channel B. Both the Rotation
Controller board and the Shutter Controller board must be selected to the same
channel.
Switches 1 through 3 are currently not used.
