In this second paper on IRMA (Infrared Michelson Array) the control and data acquisition system for the instrument are described. This paper will concentrate on a description of the computer-siderostat control system. Three personal computer based systems perform the high level control such as star catalog maintenance, current coordinate computations and siderostat/delay line position and rate computations, control of the analog to digital conversion, data storage and quick look data reduction. Low level control, such as generating the pulses that are sent to various drive micro-steppers are performed by seperate Motorola 68000 based microprocessor boards. Command words are passed between the control computers and the various microprocessor boards through a multichannel parallel-to-serial interface. These hardware systems and the software responsible for pointing and tracking with the siderostats, will be described in the text of this paper.
