Well heres the best I can do. We have a Faroudja LD200 we need some discrete codes for. Input 1,2, and 3. Apparently, they exist in RS232 form and we need to get them onto a Niles IntleControl. I am not to familiar with any of this equipment. I am trying to get this info for my boss. He programs the Niles and I do the MX remotes. I was also told this is an old unit and the IR codes don't exist. I hope this is enough details.
