Abstract
The installation of remote touch-screen and control displays typically requires several cables, to connect the display with the graphics unit for supply, video and control data. The number of cables reduces the flexibility in installations and compact display design and increases the overall system costs. The APIX technology combines high speed digital video transfer with full-duplex data communication at 2 pairs of wires, even supporting the supply of remote displays over the same cable. Based on this technology, APIX industrial offers a standardized connection of remote displays over single twisted pair cables, keeping the flexibility of application specific requirements for the communication between graphics unit and display.
Introduction
Not only since the introduction of Apple’s iPhone, but also with availability of smaller displays with higher resolutions, the demand on intuitive user interfaces using touch screen displays gains high interest in the industrial market. Human-machine interfaces like buttons or control sticks, combined with small information panels, are replaced or extended with small displays, presenting high resolution images and acting as user interface. Especially applications in the embedded market, also driven from the success of Intel’s new ATOM processor, are facing new challenges in system design and user experience. Thinking of touch-screen applications, display and processing unit may not be located in one box, requiring a robust, high speed, full-duplex link, meeting the requirements of the industrial environment for EMI and distance. This white paper analyzes the different requirements of remote display and touch-screen applications and provides scenarios and standardization proposals, how to use the APIX technolgy to economically connect a display and its processing unit with a single twisted pair cable. |
