An encoder adapter is required
if the CT002 is used with an
open-collector encoder.
This example system counts, for a specific interval, pulses from an incremen-
tal encoder that is directly connected to a rotating shaft. The PC then con-
verts the pulse count into a shaft speed (rpm). Here, the speed in rpm would
