# Getting Started ## CONNECTING THE DEVICE {% hint style="warning" %} **Attention:** * A qualified technician must install, connect, and commission the device. * Ensure the power supply is disconnected before connecting the device. * Only use components from the starter kits or the accessories supplied. * Do not use the logger's USB port for data logging, as this 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). {% endhint %} ## POWER A Molex connector provides power to the product. If the customer uses the multi-connect cables, DSub 9 or DSub 25 will be used for all other connections. {% hint style="warning" %} **Attention:** * The connector needs to be adequately tightened to ensure a proper connection and reliable operation. * Do not short-circuit any pins. * 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. * Do not use the logger's USB port for data logging, as this 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). {% endhint %} ## CAN/CAN FD ReXgen Air can be interfaced to the CAN/CAN FD bus, from which data will be logged via connector A or B. The CAN-high and CAN-low from the vehicle or machine terminals must match the CAN-high and CAN-low terminals of the ReXgen Air. ReXgen Air should be configured with the same baud rate as the device to which it is interfaced. {% hint style="warning" %} **Attention:** * The connector needs to be adequately tightened to ensure a proper connection and reliable operation. * Each end of the CAN/CAN FD bus must be terminated with a 120-ohm resistor across CAN H and CAN L. Do not short-circuit pins. * The maximum safe applied voltage is +28V. * CAN/CAN FD bus is not isolated by default; isolating devices can be purchased separately. * Do not use the logger's USB port for data logging, as this 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). {% endhint %} ## ANALOG AND DIGITAL INPUT ReXgen Air supports 2x analogue inputs in the range of ±10 V. The two analogue inputs are interfaced to the ReXgen Air via connector B (D-Sub 9). ReXgen Air also supports 2x digital inputs. The digital inputs are interfaced to the ReXgen Air via connector A on the D-Sub 9. {% hint style="warning" %} **Attention:** * The connector needs to be adequately tightened to ensure a proper connection and reliable operation. * Do not short-circuit any pins. * 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. * Do not use the logger's USB port for data logging, as this 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). {% endhint %} ## USB You can connect the device to a PC via the USB communication gateway for configuration and testing. The device is supplied with a standard Micro USB cable. Please note that the USB is not isolated; an isolator can be purchased separately. \*x1 micro USB cable to be supplied with any quantity of ReXgen Air purchased. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
