IR Code Analyser
Point any IR remote controller at this nifty device and its in-built microcontroller will quickly analyse the signal and reveal which of eight standard control protocols the controller is using.It’s a rare piece of entertainment equipment that does not come with its own remote controller. After a few years it’s easy to accumulate a drawer-full of (functional) controllers belonging to equipment long since consigned to showrooms at your local household amenity tip.Equipment manufacturers tend to use different controller protocols so it is rare to find by chance a controller from one manufacturer able to control equipment from another. All of the protocols used should however comply with one of the eight industry standards.
