Would you happen to have information on setting up a A7 selector on short (dummy) floors? It's a 4 stop front and rear, short run is from 2R to 3F. Existing Selector has 8 tapes (4 Lanes) with the lane closest to the rail is doors, 2nd lane from the rails is leveling, stop, 3rd lane is a duplicate double stepper setup of lane 2, and lane 4 is positioning. Everyone I have spoken to has never heard or seen this configuration. All documents I have seen so far only show 3 lanes or 6 tapes for the A7 selector.
