12vDC you must then adhere to the connection scheme above. If you are unsure
of the connec
tions it is UNLIKELY that you will cause any damage by taking a ‘try
and see’ approach. If your motor is connected correctly you will be able to slew
the focus motor in a very smooth fashion using either the MHP hand controller or
the software focus functionality. A jumpy motor is a symptom of incorrect wiring.
DO not connect the focus output to any other motor other than a
unipolar (5 or 6 wire) stepper motor.

If you wish to reverse the direction of the DC motor rotation you can
safely swap around DC+ and DC-. Alternatively, you can achieve the
same result via the PC software.
The voltage output on the DC motor port is very close to the input
voltage from your power supply. Ensure that the DC motor you use is
rated for this voltage. Most times this is very close to 12V. Plugging a
motor which is not rated to handle this voltage will damage your motor.
