Hello

I am not sure about your first question. But the second question with the (2) high speed outputs, they can be used for either Pulse Width Modulation (PWM) or Pulse Train Output (PTO). The PWM is similar to an analog signal to where you could very the output from zero to full scale. An example would be controling the speed of a motor through a drive, a common signal could be 0 to 10vdc.
The PTO instruction sends out pulses commonly used for motion control to where a number of pulses would move a servo or stepper motor a number of pulses.
When using these instructions use the dc not relay outputs if you have relay outputs they sell a signal board 0-5vdc or 0-24vdc. The link below will explain in more detail the where and whys and walk you through the setup.
