Using a radio frequency channel (RF channel) between 11-26, the BaseStation synchronizes OptiTrack cameras with Active Tags and Pucks. Once the BaseStation has the signal from the active component, it then sends that data to the Motive computer along the camera network. This allows Motive to recognize Active Pucks and Tags even with significant occlusion of the LED markers compared to passive markers. If you use Active Tags or Pucks, at least one BaseStation is required per tracking system. For larger volumes, the approximate range from BaseStation to Tags/Pucks is 100’. For more information regarding the specifications of the BaseStation, please visit our [Support ](https://optitrack.com/support/accessories/active-basestation.html)section of the OptiTrack website. ![](https://2142239968-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FTSFWA3dBvgCMGQlNWsHE%2Fuploads%2FHZgLE5Y0pZQ31sbidnfm%2Fimage.png?alt=media\&token=ce9cb90e-bffa-449b-8d14-87ee6f7a2a60) ## **BaseStation LEDs** *Note: Behavior of the LEDs on the BaseStation is subject to be changed.* * **Communication Indicator LED:** When the BaseStation is successfully sending out the data and communicating with the Active Pucks, the LED closest to the antenna will blink in green. If this LED lights up in red, it indicates that the BaseStation has failed to establish a connection with Motive. * **Interference Indicator LED:** The middle LED is an indicator for determining whether there are other signal-traffics on the respective radio channel and PAN ID that might be interfering with the active components. This LED should stay dark in order for the active marker system to work properly. If it flashes in red, consider switching both the channel and PAN ID on all of the active components. * **Power Indicator LED:** The LED located at the corner indicates power for the BaseStation. This LED may be disabled on BaseStations with the latest firmware, but on older BaseStations, this LED may light up in red to indicate power. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.optitrack.com/v2.3/active-components/active-components-hardware/basestation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
