1. Setup
The TOC is provided with various gears to fit almost any broadcast or cinema lens.
Select the proper gear pitch for the proper lens ring.
The gears can also be switched to
either side of the motor if needed.
Warning: If you are using the TOC with a servo powered lens, make absolutely sure
that the lens servo for the function you’re trying to control is always deactivated,
otherwise the lens servos can end up fighting the TOC motors resulting in severe
damage to either the lens or the TOC system. Please be aware that some “full auto”
modes may override the lens servo switches. Check with the lens or camera
manufacturer’s user manual to ensure that this won’t interfere.
POWERING THE RECEIVER: Only use a VariZoom-supplied cable to power the
TOC receiver. It is very important that you power the receiver with a maximum of
24VDC regulated (actual measured voltage – some nominal unregulated 24VDC
sources can actually go as high as 34VDC). The acceptable range for voltage is 12-
24 VDC – if you go higher, the unit will be damaged severely.
Before connecting power, mount the TOC motors onto 15mm or 19mm mattebox rods.
The motors can be mounted either vertically or horizontally.
