This port is designed to accept the built-in hall-encoder from the [NEO Brushless Motor](http://www.revrobotics.com/rev-21-1650/), but it can also connect to other external encoders when running in Brushed Mode. The connector details can be found below. {% hint style="info" %} The SPARK MAX can be configured to run in [Alternate Encoder Mode](/brushless/spark-max/encoders/alternate-encoder.md), which reconfigures the Data Port on the top of the controller to accept an alternative quadrature encoder in addition to the Encoder Port. {% endhint %} ![](https://cdn8.bigcommerce.com/s-t3eo8vwp22/product_images/uploaded_images/encoderportpinout.png) #### Encoder Port Connector Information | **Connector Pin** | **Pin Type** | **Pin Function** | | :---------------: | :----------: | :---------------: | | 1 | Power | Ground | | 2 | Digital | Encoder C / Index | | 3 | Digital | Encoder B | | 4 | Digital | Encoder A | | 5 | Analog | Motor Temperature | | 6 | Power | +5V |

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.revrobotics.com/brushless/spark-max/specs/encoder-port.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
