• Pin #24 Sequence In receives a close contact input to advance the sequence one step. This input does not start a
sequence but forwards the presently running sequence by one step.
• Pin #25 Sequence Out supplies a negative pulse when the sequence running on the multiscreen monitor advances one
step.
