==== Get odometer from ====

  * **GPS (Km/h)**: uses the GPS of the phone or tablet, in kilometres.
  * **GPS (MPH)**: uses the GPS, in miles.
  * **RabbitBox**: the old Bluetooth Rabbit Box units.
  * **RabbitBox v2**: the Wi-Fi Rabbit Box units. Choose **S1**, **S2** or **Average** (the average of both sensors).
  * **Rabbit PRO**: choose **S1**, **S2**, **Average** or **GPS** (the Rabbit PRO's internal high-precision GPS).
  * **RabbitConnect**: connection to another device by IP address (S1, S2, Average or GPS).
  * **Steps (Mts/Min)**: for measuring on foot. Each press of the headset button counts one step.

Select the option and tap **Connect**. The connection status appears below. For a **RabbitBox v2**, the Designer asks for your Rabbit Box number.

**Which option should I choose?**

  * To measure the rally as precisely as possible, use the sensors of the Rabbit PRO or the Rabbit Box, and [[en:roadbook-designer-organizadores:empezando-a-dibujar:calibrar-con-rabbit-box|calibrate them]] before you start.
  * For the [[en:roadbook-designer-organizadores:empezando-a-dibujar:tramo-de-calibracion|Calibration stage]], use the Rabbit PRO **GPS** with R = 1.

<WRAP caution>
The Designer keeps two calibrations: one R for the **phone GPS** and another R for all the other connections (Rabbit Box, Rabbit PRO, RabbitConnect and Steps). After changing the connection, always check the R on the [[en:roadbook-designer-organizadores:empezando-a-dibujar:elementos-de-la-pantalla-de-calibracion|calibration]] screen.
