I found nothing in the product manual on IR code format. A search of the internet using Google indicates Onkyo uses NEC codes which would be compatible with the EZUIRT. HOWEVER, i suggest confirming that with the manufacturer or sales location. Not all information on the internet is accurate when not from the manufacturer which these hits were not.
