（2）Incremental encoder PG card with Frequency division
The input signal of the IR610-PG-INC2 crossover PG card can be differential or open collector type,
selected by the DIP switch; there are two sets of output signals, open collector type and
differential output type; The card's port definition is shown in the table below.
