Paper Abstract

Instruments and telescopes being planned for the US community include a wide assortment of facilities. These will require a consistent interface. Existing controllers use a variety of interfaces that will make using multiple controller types difficult. A new architecture that takes maximum advantage of code and hardware re-use, maintainability and extensibility is being developed at NOAO. The MONSOON Image acquisition/Detector controller system makes maximum use of COTS hardware and Open-Source development and can support OUV and IR detectors, singly or in very large mosaics. A basic requirement of the project was the ability to seamlessly handle even massive focal planes like LSST and ODI. Software plays a vital role in the flexibility of the MONSOON system. The authors have built on their experience with previous systems (E.g. GNAAC, wildfire, ALICE, SDSU etc.), to develop a command interface, based on a dictionary of commands that can be applied to any detector controller project. The Generic Pixel Server, or GPX, concept consists of a dictionary that not only supports the needs of projects that use MONSOON controllers, but the set of commands can be used as the interface to any detector controller with only modest additional effort. This generic command set (the GPX dictionary) is defined here as introduction to the GPX concept.
