A multi-access automatic circle reading system for Chinese-Danish Meridian Telescope has been developed in CSAO. It consists of circle scanners and photon-electric counters. The method, in using TP-801B Single board computer as main controller for the system, is proved to be successful. It has advantages with low cost, high quality and easy operation. One CTC chip, three PIO chips and relational circuts are all of I/O interface. These programable chips are provided in the board or expanded by designer.
