If the controller or PLC being used with the INT-462/IB462H has a voltage
output, this may also be used to power the opto-couplers.
If this mode of powering the logic inputs is used, the shunt on JP2 must be
placed between pins 1 and 2 (factory default placement).

The on-board +5 VDC can be used to power the logic circuitry by positioning
the shunt on jumper JP2 between pins 2 and 3 (See figure 2.1.5).
Note that if this method is used, optical isolation is defeated and any electrical
noise on the logic inputs will be coupled onto the driver output, i.e. noise on
the step clock input will cause the motor to run rough.
