If your dome has a shutter or flap controlled by a separate Caterpillar board, enable it in the Shutter section of Initial motor configuration and settings.
- Check Enabled?. The shutter controls will become active.
- Select the shutter motor preset from the Shutter preset dropdown.
- If your shutter has two elements—a main opening and flaps (AKA lower shutters)—check Has flaps?. Note that the flap motor must be DC (motor or linear actuator), and flaps require their own open and close limit switches. There is currently nothing to configure for flaps.
- Click Save configuration to the board.
On power on, both boards connect to each other over a private, internal Wi-Fi link—this is automatic and requires no configuration from you. The observatory computer must be connected to the rotation board, which can be done via USB or your own Wi-Fi network. The rotation board controls the shutter board; you do not need to address the shutter board separately from ASCOM. Similarly, the rotation board will automatically update the firmware of the shutter one when required.
