ADC Control

The ADC control window (shown in Figure ) contains a display of the ADC prism angles and buttons to allow the ADC to be nulled, stopped or set to track a specified telescope position. In normal operation this window is not needed as the ADC can be controlled from the telescope control window.

User interaction is typically limited to using the 5 buttons on the bottom left. If the system has failed for some reason, these allow the user to recover ADC operations by slewing the ADC to the desire position. The options are:

Stop the ADC -- This should be done at the end of the night

Set tracking -- To start the ADC tracking with the telescope

Null ADC -- Null both elements, remove the ADCs corrective power

Slew to Tel Pos -- Rapid slew the ADC to match Telescope position

Update Position -- never used
