Using the R325P with more than 5V
You can choose to supply the optos with the R325P’s internal 5V supply by jumping pins 1 to 4.
But if you choose to use more than 5V, for example, a 24V supply and the step pulse train is also
a 0 to 24V low-high signal, please use the following recommended resistor to limit the current to
10 mAmps. Note: no resistor will be needed on the actual opto supply line, pin 1.
