After the motor has been mounted on the rod, secure the gear against the proper lens ring 
and tighten the dovetail clamp. Mount your TOC receiver and attach the antenna.   
First plug the lens motor into TOC receiver (yellow to yellow) 
Then plug power from camera into TOC receiver (red to red). Do not plug lens motor 
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 3.

 

To execute auto calibration from the hand 

unit, select “Calibrate” from the home menu, then select “Automatic”.  The motor will 
start moving automatically, and will also automatically stop once resistance is met.  Do 
not touch the lens motor 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)
