After the motors have been mounted on the rods, secure the gears against the proper lens
rings and tighten the dovetail clamps. Mount your TOC receiver and attach the antenna.
First plug the lens motors into TOC receiver according to their function (yellow to
yellow, focus to focus, etc)
Then plug power from camera into TOC receiver (red to red). Do not plug lens motors
into receiver while it is already powered up – this is called ‘hot swapping’ and it can lead
to minor malfunctions – always plug power into receiver LAST.
Now put the battery in the hand unit, attach the antenna and turn on the power by holding
down the power button for at least two seconds. All five LED lights on both the receiver
and the hand unit should now be solid orange.
Assuming your lens has mechanical end stops (like most broadcast or cine lenses), the
TOC motors will calibrate most accurately in “Auto” mode. Note: If using a lens that
doesn’t have end stops (e.g., DSLR lenses), you must manually calibrate the lens
motors. This will be addressed in chapter 5.
To execute auto calibration from the hand
unit, select “Calibrate” from the home menu, then select “All Motors”. (This will be
described in more detail in chapter 5) The motors will start moving automatically, and
will also automatically stop once resistance is met. Do not touch the lens motors
during calibration. Also note that the power required to move the lens rings properly
may vary depending on the lens used. The system defaults to 50% power and can be
adjusted. (see page 8 for more details). 50% may be too much for most lenses, and can
cause the lens motor to slip off the lens ring or skip gear teeth. Adjust power down if this
happens.
