**Magnetic Encoder Servo** PC Software Installation Package path:  [Appendix/ServoStudio_0.1.1_x64-setup.exe](https://drive.google.com/drive/folders/1G2VSZiqwqcjcrp59oCFjL_C3VDzehWqo)

The wiring diagram for the servo control board is shown below. Power the board with a 12V power supply and connect the servo control board to the computer using a Type-C cable. Connect the magnetic encoder servo to the board.

Follow the steps:  
Change the **Port** number to the one found (in this case, change to **COM10**\)   
-> Set the baud rate for **HX-30HM** to 1000000 

> [!NOTE]
>
> **The baud rate may vary for different magnetic encoder servos. Refer to the corresponding model's user manual for specifics.** 

-> Click **Connect**
-> Click **Scan**
