| Abstract: | I/O card with RS-232 interface consists of D/A, A/D, I/O, high-speed light-coupled, electric level transition, RS-232 interface and micro-controller, and its testing functions are realized with LabWin/CVI. The communication of I/O card is programmed by calling RS-232 function library, the GUI is created and the frame of program is automatically produced by using LabWin/CVI Editor, after opening serial port and calling the I/O port configuration function, the card can be controlled. Through the communication between PC and RS-232 interface, a small testing system for industrial field can be directly formed controlled by computer. |
