This switch changes from 1 pulse t two pulse mode. In 1 pulse mode the
CW connecton becomes PULSE and te CCW connection become CW/CCW. So high
on CW/CCW is clockwise and low is CCW. The motor moves one step for
every state chane of on to off of the PULSE terminal.

2 pulse mode is simply motor moves the direction of the connection of
every state change from on to off.

According to my book it Oriental Motors book it says that the timing
signal goes hight at the begging of every sequence from power on as 0.
In full step mode that is 10 pulses and 20 pulses in half step mode.
