[TenTec] Optical Encoder operation

[Mark Erbaugh]

I believe I understand the basic operation of an optical encoder, such =
as the 302. As you turn the knob, a series of holes on a plate connected =
to the shaft generate a series of pulses which the Pegasus software =
counts and convert into a value indicating movement.  My question is how =
does the Pegasus determine which way (CW or CCW) the knob is being =
turned?
