Design of Universal I/O Control Board Based on Parallel Port

We discussed the implementation of the computer Industrial control and micro-computer interface experiments based on the parallel port. A kind of general control panel was designed through universal languages, such as 86 serial compiling language, VB, VC++ and so on. Therefore, the computer-controlled interface experiments can be done conveniently. It can be practicable for higher colleges and secondary professional schools to do experiments in such fields as computer interface, PC computer control and automatic control of industrial device.
