{% hint style="info" %}

#### Note:

* Pins not mentioned in the description table(s) are NC.
  {% 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).
  {% endhint %}

{% hint style="danger" %}

#### Warning:

* The connector must be tightened securely to ensure proper connection and reliable operation.
* Each end of the CAN bus must be terminated with a 120 Ohm resistor across CAN H & CAN L.
* Do not short-circuit any pins.
* The maximum safe applied voltage for analog and digital I/P is ±28 V
* Please do not use the logger's USB port for data logging, as it may damage the port and will not be covered under warranty.
* ReXgen Air is an IP50 device (please ensure it is covered when mounting it in locations that may have water ingress).
