# Interface RS485 

If multiple BMS systems are used within the same network, every unit must be assigned a **unique ID** to ensure proper communication and avoid addressing conflicts.
The ID is defined in the source code. The ID starts with `1`and for a second BMS you have to type `2`. To change it, you must edit the following header file: 
`Firmware\EET_BMS\CM4\Core\Inc\RS485_Communication.h` 

| Settings            | parameter  |
| ------------------- | ---------- |
| the ID for each BMS | `RS485_ID` |
