In today's A/V industry it's common to design, install and maintain a system that relies on other devices, either farther upstream or downstream in the system, for operating power. HDMI signal-sensing auto-switches, DisplayPort VGA adapter dongles and the embedded media converters in RapidRun Optical cables are just a few examples of common bus powered A/V solutions. Sometimes these devices rely on the power supplied through the signal connection, such as the bus found on pin 18 of the HDMI connector. Sometimes there is an auxiliary USB connection that is used solely to source power from a convenient display, source device or stand-alone power source.
It has never been more important to have a clear understanding of the limitations of various common bus powered devices. Interactive video panels rely on USB connectivity. Auto-switching solutions rely on power delivered by the video source. Digital-to-analog converters (DACs), media converters and signal extenders embedded in cables and termination boxes often depend solely on the power supplied by the video or audio source. Do you know that your system will perform, or are you just hoping it will? This course will help you avoid the most common pitfalls of bus powered A/V solutions and ensure that your system delivers quality, dependable performance.
