The sequencer have 5 diferent states, current names are Gear Up, Step1, Step2, Step3 and Gear Down.

The time spent on each of intermediate states is defined in 0,1s increments.

On each of these states you define the output position of the 5 outputs. You can have, for example, one output closed in first step, opened in second step, closed in 3th step, opened in 4th step and closed in 5th step. All outputs are independent of the others and nothing is preset, it is not defined that the gear output should be open in gear down and closed on gear up, you decide. You can use diferent valves for the nose to the mains and have the nose extending at different time than mains.

The output commands for "open" and "closed" are programmable independently for each output, so you can use servos for the doors and adjust electronically the door endpoints.

Hope this explain how the sequencer works.
