MOTR.S Quick Start Guide

Updated on

Completely redesigned from the ground up, MOTR.S Lens Motors set a new standard in lens control technology. MOTR.S Motors are ultra-lightweight, compact, and blazing fast at up to 297 teeth per second. MOTR.S delivers 0.3Nm peak torque and boasts durable, all-aluminum construction and reinforced sockets, and a revolutionary quick-release gear system for intuitive setup and quick transitions. They are compatible with all previous RT handsets, receivers, and daisy-chainable motors.



  • FIRMWARE UPGRADE: Click here to update your product to the latest firmware before use.
  • PRODUCT REGISTRATION: Click here to register your eligible products and gain access to premium technical support.
  • TERADEK RT APP: Click here (only available on iOS) to download the Teradek RT App. 
  • RT MANAGER DESKTOP APP: Click here (Windows/Mac OSX) to download the RT Manager Desktop App.



  • MOTR.S is a powerful device that is capable of causing injury or damage. Use caution when touching the drive gear if the device is powered on. 
  • MOTR.S is not to be used on extremely stiff or damaged lenses.
  • MOTR.S requires no user maintenance. Opening the motor can affect its internal calibration and void the warranty.
  • The motor body is used as a heatsink for the brushless windings. It may get warmer than a brush-type motor.
  • Power input must not exceed 32V. Ensure that the power source’s voltage is between 7-32V. Exceeding 32V can damage the motor and void the warranty.


MOTR.S powers up once it is connected to a Teradek RT device.

  1. Attach the motor to the camera support rod.
  2. Rotate the lens ring so that it’s not too close to either end stop, then mesh the motor's drive gear with the lens ring gear.
  3. Tighten the rod clamp knob (E).
  4. Connect power from the receiver to either motor input (D) using a 4-pin connector. The motor(s) will then begin calibrating. NOTE: Power input must not exceed 17V. If connecting multiple motors, use a separate 4-pin connector to “daisy-chain” the other units together.
  5. If you see evidence of backlash affecting accuracy, ensure that your mount, rails, and camera are extremely rigid, as mounting flex is the main cause of inaccuracy.

Pin-Out Connection and Descriptions


To manually assign an axis (Focus, Iris, Zoom) to the motor(s), press and hold the Axis Button (C) for one second, then release it once the correct class indicator is illuminated. 


  1. Disconnect the power from the motor.
  2. Remove the MOTR.S from the support rod.
  3. Use a flat-head screwdriver to remove the gear screw that secures the motor drive gear.
  4. Carefully remove the gear and affix it to the opposite wheel. Ensure that the pins on the wheel are aligned with the holes in the gear.
  5. Insert and secure the gear screw.
  6. Attach the motor to the rod support by realigning and positioning the gear to reach the lens gear, then tighten the rod clamp knob.
  7. Connect power from the receiver to either motor input (D) using a 4-pin connector. The motor(s) will then begin calibrating.


Other performance parameters (performance mode, the direction of rotation, etc.) can also be modified from any controller or receiver MOTORS menu. Below is a list of available motor-specific menu items.

Navigate to the MOTORS menu on the controller or the receiver to adjust the following menu options:

  • RECALIB - Calibrate end stops for the motors
  • RESPONSE - Press SET to adjust the motor’s response time (Normal, Slow, or Fast)
  • SET SERIAL - Press OK to change the motor(s) serial number
  • ACCURACY - Press OK to alter the motor’s backlash compensation, then SET to make your selection
  • TORQUE - Adjust the motor torque settings (Low, Medium, or High)


The Teradek RT App for iOS devices allows users to configure all of the major functions via Bluetooth such as motor axis selection, creating lens maps, start/stop, and includes virtual sliders for calibrating FIZ controls on the MDR.X and MDR.S. 


  1. Download the Bolt App.
  2. Navigate to ADV>BLUETOOTH on the MDR.S, then select YES to enable.
  3. Enable Bluetooth on your cellular device, then open the Teradek RT app. Your device will automatically detect your MDR.S if it is within range.
  4. Select the RT device(s) you want to configure (Receivers, Controllers, or ACI).
