Abstract
We have built a control system for a mini survey facility dedicated to photometric monitoring of nearby bright (K<5) stars in the near-infrared region. The facility comprises a 4-m-diameter rotating dome and a small (30-mm aperture) wide-field (5 × 5 sq. deg. field of view) infrared (1.0–2.5 microns) camera on an equatorial fork mount, as well as power sources and other associated equipment. All the components other than the camera are controlled by microcomputerbased I/O boards that were developed in-house and are in many of the open-use instruments in our observatory. We present the specifications and configuration of the facility hardware, as well as the structure of its control software.
