Digital signal was transferred from the output terminal to the receiving end, which was consisted of continuous high or low level represent 0 and 1 as digital signal, and latch, test it through serial or parallel mode. Our experiment simulated the producing equipment of sequence signal, the signal conversion module, testing module of serial and parallel mode, latch output and control circuit. It implements a simple serial port data communication model. In the experiment, we use the combination of simple chips to realize the function that transport, transfer and test a sequence of the digital signal consisting of 0 and 1, and display it on LED Segment Displays. In addition, we realize the control of display. The LED Segment Displays works only in specific conditions. We also conduct simulations on QuartusⅡ.
