i got an 15" Touchsreeen




It works fine!!
But what i cant find out completely is: For what are (some of) the Keypad Buttons?
Ok i can select "Fixture" and then a number and "Enter" and the desired Fixture is selectet. Same with the "Groups" Button.
But how does the "Fix. Channel", the "+", the "@", the "thru" and other Buttons work? When i press for example "Fix.Channel" "1" "@" "200" i thing that the channel 1 of the selectet Fixture should be 200 but ist is not 200 it is set to a different level.
Can somebody explain these Buttons to me?
Excuse my bad english!
