I've had a Vantage Q-Link system installed in our home when we first built it in 2000. Several modules with roughly 40 switches. The installer initially showed me how to change scenes with my PC via the RS232 input, however it's been many years since then. The installer is no longer in the industry (no clue what happened to him), and support is difficult to come by. I don't have the latest software which I believe is 4.8. Unfortunately, this is software only available to dealers, and I no longer have a dealer nearby. So it's quite costly calling someone from the nearest city and paying for travel time along with programming for a simple scene change, that will take me less than 5 minutes.

Does anyone here have the software and the supporting manual/documentation?

Thanks!
