{% hint style="danger" %}
**Warning:**&#x20;

* The connector needs to be tightened properly to make a proper connection, ensuring reliable operation.
* Each end of the CAN bus must be terminated with a 120Ω resistor across CAN H & CAN L.
* Do not short-circuit any pins.
* Do not use the logger's USB port for data logging, as it may damage the USB port, which won't be covered under warranty.
