{% hint style="info" %}

#### Notes:

* 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 120 Ohm resistor across CAN H & CAN L.&#x20;
* Do not short-circuit any pins.&#x20;
* The maximum safe applied voltage for analogue and digital I/P is ±28 V.
  {% endhint %}

{% hint style="warning" %}

#### Attention:

* To set up a USB via the Molex connector, please specify this requirement when ordering, or the device must be sent back to Influx (as this requires some hardware modification).
