Patent Number: 8,817,006

Title: Adapter

Abstract: A display adapter includes first and second conversion circuits, a switch unit, and a video graphics array (VGA) interface. The first conversion circuit includes a digital to analog (D/A) converter and a coupler. The second conversion circuit includes an analog to digital (A/D) converter and a decoupler. When the switch unit connects the first conversion circuit to the VGA interface, the D/A converter converts a digital signals representing VGA data into a first analog form data for coupling with a first alternating current (AC) voltage. When the switch unit connects the second conversion circuit to the VGA interface, the decoupler decouples and separates a second analog form data into the second analog form data. The A/D converter converts the second analog form data into digital signals representing VGA data, and outputs the digital signals representing VGA data to the VGA interface for use by another VGA display device.
