#### 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).
* ReXgen Air is an IP50 device (please ensure it is covered when mounting it in locations that may have water ingress).
* Signal inputs (CAN, analogue or digital) should not exceed ±28 V.
* For stable operation, ensure all sensors and inputs share the same ground as the unit's power supply.
