Cable-IMU




text1







Overview

The IMU Cable is a dedicated communication cable designed for use with the KonteX Commutator Pro and an optional IMU Sensor mounted on the animal's headstage. The IMU Sensor continuously measures the animal's rotational movement and orientation, while the IMU Cable transmits this motion data to the Commutator Pro in real time.
During freely moving experiments, animals may rotate continuously, causing tethered cables to twist and accumulate mechanical torque. Using the motion data received from the IMU Sensor, the Commutator Pro automatically rotates in the corresponding direction to compensate for the animal's movement. This active cable management minimizes cable twisting, reduces mechanical stress on implants and cables, and helps preserve natural behavior throughout long-term experiments.
The IMU Cable is dedicated exclusively to IMU communication and does not transmit neural recording, stimulation, or video signals.
To accommodate different laboratory layouts and experimental requirements, the IMU Cable is available in 1 m, 2.5 m, and 5 m lengths.

Key Features

  • Real-Time Motion Tracking
    • Provides continuous transmission of motion data from the optional IMU Sensor to the Commutator Pro for accurate real-time movement tracking.

  • Automatic Cable Twist Compensation
    • Enables the Commutator Pro to automatically rotate in response to the animal's head movement, reducing cable twisting and improving long-term experimental stability.

  • Dedicated IMU Communication
    • Designed exclusively for IMU sensor communication and power. Neural recording and stimulation signals are transmitted through the headstage cable independently.

  • Multiple Cable Length Options
    • Available in 1 m, 2.5 m, and 5 m cable lengths, allowing users to select the most suitable configuration for their experimental environment.

  • Lightweight and Flexible Construction
    • Manufactured using lightweight, high-flexibility materials to minimize cable drag and reduce interference with natural animal behavior.




    Compatible Systems

  • KonteX Commutator Pro
  • Optional IMU Sensor Module




    • Applications

    The IMU Cable is intended for freely moving behavioral and electrophysiological experiments where automatic cable management is required. When combined with the optional IMU Sensor and the Commutator Pro, the system continuously compensates for the animal's rotational movement, helping to prevent cable twisting without affecting neural signal acquisition.




    Connection Orientation

    The IMU Cable connects the optional IMU Sensor to the dedicated GYRO port on the KonteX Commutator Pro. Correct connector orientation is essential to ensure reliable communication and prevent damage to the connector.

    Before connecting the IMU Cable, identify the two sides of the connector as shown in the figure.
  • Wire Side – The side where the wires and crimped terminals are visible.
  • Contact Side – The side where the metal contacts are visible.
    • When inserting the connector:
  • Align the Contact Side toward the GYRO receptacle, where the electrical contacts mate with the connector inside the port.
  • The Wire Side should face away from the receptacle opening, as illustrated.
  • Gently insert the connector until it is fully seated. Do not apply excessive force.


    • Connector Installation

    text1

    1. Locate the IO Port GYRO connector on the Commutator Pro.
    2. Identify the Wire Side and Contact Side of the IMU Cable connector.
    3. Align the Contact Side with the GYRO receptacle as shown in the illustration.
    4. Carefully insert the connector until it is fully seated.
    5. Verify that the connector is securely connected before operating the system.




    ⚠ IMPORTANT :
    • Connector Orientation
    The GYRO interface uses a JST XSR 0.6 mm pitch connector with delicate miniature contacts. Always verify the connector orientation before insertion. Incorrect insertion may bend the connector pins or permanently damage the receptacle.

    • Do Not Force the Connector
    If resistance is encountered during insertion, stop immediately. Remove the connector, verify the orientation, and reinsert it gently.

    • Proper Handling
    Always hold the connector housing when connecting or disconnecting the IMU Cable. Do not pull directly on the cable.

    NOTE: Always secure any excess cable firmly into the integrated screw clips on the commutator as illustrated. To ensure maximum stability and prevent the tether from being accidentally pulled or strained during vigorous animal activity, it is highly recommended to pair your setup with the Fine-Cable Organizer Kit.
    Proper anchoring eliminates cable tension, maintains unhindered rotation, and ensures optimal tracking sensitivity.


    ⚠ IMPORTANT: Ensure that all tether cables are securely routed and fastened through the integrated screw clips. Failure to properly anchor the cables may result in accidental disconnection or tether dislodgement during experimental procedures.
