I'm having some weird problems with the SG9120 positioner. When first installed all worked as expected. After a short time I had an issue where it wouldn't move unless I had selected a Vertical channel. Well I had a lot of things going and never got to checking this out and finding out if maybe was a switch or the PCI card or cabling. Last week I was in need of using the 1 meter WSI dish on this motor and hooked it up by itself to the PC. I dialed up the sat I wanted and watched my show . Well I'm having issues again. This time it won't move at all,USALS or DiSEqC 1.2, but if you use a simple Move west or east command, off it goes like nothing was wrong. It responds to the Stop call just fne too. Now I also have a Winegard2076 on a SG9120b I bought at the same time and it operates with no problems on the same PC setup, same settings. Did my motor develop "selective hearing" and doesn't process all commands?
