Abstract
RTS2, or Remote Telescope System 2nd Version, is a modular observatory control system. Development of RTS2 began in 2003 and since then it has been used at more than 20 observatories world-wide. Its main users are small, fully autonomous observatories, performing target of opportunity observations. Since June 2007 RTS2 has been used at Brookhaven National Laboratory (BNL) to control the acquisition of images for the Large Synoptic Survey Telescope (LSST) CCD characterisation. The CCD test laboratory includes multiple devices which need to be controlled in order to perform the electro-optical testing of the CCD. The configuration of the devices must be recorded in order for that information to be used later during data analysis. The main factors leading to use of RTS2 were its availability, open - source code, and modular design which allows its fast customisation to fit changing needs of a R&D project. This article focuses on the description of changes to the system which allow for the integration of LSST's multiple output CCD imagers. The text provides details of the multiple channel implementation, which parts of the system were affected, and how these changes influenced overall system design. It also describes how easy and fast it was to run the multiple channel instrument on night and twilight sky during prototype CCD testing, and demonstrates how the complex routines, such as twilight skyflats acquisitions, worked out of the box.
