Three-Channel Motor Driver for Cinema Lenses

The Teradek RT MK 3.1 drives up to three motors for focus, iris and zoom control on industry-standard cameras. It receives wireless commands from compatible Teradek controllers at distances up to 5000 ft. The unit mounts directly to the camera for integrated lens management.

Capacity and Headroom

Three motor channels cover full FI+Z operation on a single receiver. Range extends to 1.5 km line-of-sight, giving reliable control across large sets. Auxiliary ports add two analog inputs plus trigger and serial links for extra accessories. The system stops at three motors; productions needing more axes must add another receiver.

Calibration and Protection Features

Automatic and manual soft-stop calibration adjust end-points without user intervention. A proprietary torque algorithm limits motor force to protect delicate lens mechanics during fast moves. Run/stop control triggers recording on supported cameras directly from the handset. No bundled software or accessories are included beyond the receiver itself.

Questions about this item

Will the RT MK 3.1 drive my existing Teradek motors for focus, iris and zoom?

Yes, it supports up to three motors for Focus, Iris and Zoom control, so your current motors can be connected directly.

How can I verify the receiver is linked to my controller at distance?

The unit receives commands from a Teradek 4-Axis or 6-Axis Controller up to 5000 ft (1.5 km) away; a solid link indicator on the controller confirms operation.

Does the box include the three motors and cabling, or must I buy them separately?

The receiver is supplied alone; motors, cables and a compatible Teradek controller are purchased separately.
