I have a customer with 8 Sharp Aquos model LC-C6554U. My job is to control them using a Creator control system via Infrared. The customer wants to switch back and forth between the local TV tuner and HDMI inputs. I found discrete commands for Sharp at remotecentral.com, however, they're labeled input 1, input 2, input 3, input 4 and input 5. My question is simply which one of these inputs is the local TV tuner and which is the HDMI?
