Using IMDP23’s Internal 5VDC supply for optos:
If using the internal 5VDC supply,
simply connect PIN 6 to PIN 7.
Be sure to connect step pulse
ground to the Silverpak’s Ground,
PIN 2.
Changing direction and disabling
the drive is achieved by
connecting these two inputs to
PIN 2, ground.
This type of connection no longer
optically isolates the inputs.

Using more than 5VDC for external supply for the optos:
If using more than 5VDC, connect
resistors in series with each of the
3 inputs: step, direction, enable.
Use the table in the previous
section to determine what resistor
to use.
