I need help from anyone willing.I was an integrator about ten years ago. I became a manufacturers trainer (Niles and Colorado vNet) and have not programmed any RTI stuff. I had reprogrammed her Colorado vNet system and she asked if I could change some codes on her RTI . She changed Directv STD to an HD box. I think by what I can recall it looked like one of the TC-2 models. Is there a manual available can it be manually programmed or do I need the Integration Designer software with cable. I don't have either.I have friends who work at many manufacturers but not RTI. The original programmer on this job is nowhere to be found. Can someone help me help her?
