Abstract

The measuring data acquisition methods from local sensor are many kinds of techniques. But, if sampling time is not important and we need data of many sensors it is more resonable to be applied economical system. In this paper, the data acquisition technique is used two RS232C communication signals simultaneously. The one come from computer serial port, and another is signal changed from parallel port. In this case the circuits would be simplification and that communication cable is connected by Parallel instead of Branch connection.
