Overview

The Tilta RS-03-AM is a dedicated run/stop cable for the Nucleus-M Wireless Lens Control System, enabling camera operators and focus pullers to start and stop recording remotely. By connecting one end to a Nucleus-M motor and the other to a camera's 3-pin Fischer run/stop port, the cable routes the record trigger command through the existing wireless hand unit. This eliminates the need to physically access the camera during a take, which is particularly valuable when the camera is mounted on a gimbal, jib, crane, or other hard-to-reach position.

As a single-purpose accessory, the RS-03-AM is designed for professional workflows where the Nucleus-M system is already deployed for wireless focus, iris, or zoom control. The 3-pin Fischer connector is a standard found on select cinema cameras and professional video equipment, providing a secure locking fit that resists accidental disconnection during production. Users should confirm their camera uses this specific connector type before purchasing, as Tilta offers different cable variants for other port standards.
