In the Toolkit help file it says; Programming with level translation mode Using the level translation mode, there are four movement controls which allow the user to open and close devices, change device motor direction (toggle) and stop motor action. The light levels in level translation mode are restricted to 0%, 3% to 97%, and 100%. [B][I]The light levels of 1%, 2%, 98% and 99% are reserved values which correspond to the following internal commands: Close Shutter, Stop Shutter, Toggle Shutter, and Open Shutte[/I][/B]r in the Single channel shutter relay I get them as; Close = 0%, Close toggle = 1%, Stop=2%, Toggle=98%, Open toggle=99%, Open=100% is the help correct ???? dave
