DUAL VIDEO GRAPHICS ARRAY CONNECTORS TESTING SYSTEM

摘要

A dual VGA connectors testing system includes an exchanging module and a controlling module connected to the exchanging module. The exchanging module includes a number inputting terminals and a number of outputting terminals. First group of RGB signal inputting terminals are connected to RGB signal outputting terminals, first group of scanning and controlling signal inputting terminals are connected to scanning and controlling signal outputting terminals, and first group of address signal inputting terminals are connected to address signal outputting terminals when the controlling module outputs a first signal; second group of RGB signal inputting terminals are connected to the RGB signal outputting terminals, second group of scanning and controlling signal inputting terminals are connected to the scanning and controlling signal outputting terminals, and second group of address signal inputting terminals are connected to the address signal outputting terminals when the controlling module outputs a second signal.
