Question about this:
"When in REV position, a rising edge on the REVERSE jack causes the
sequence to reverse direction and keep going even after the pulse is
removed. A second pulse reverses the direction again."
How does one specify the starting direction? Do you first select UP
or DOWN and then switch it to REV?

Yes. You start your module in a known state by setting the direction
explicitly with the switch. If I had more panel space, I'd probably
put a separate UP jack and DOWN jack.
