ReXgen Air uses:
FAKRA C connector (Blue) for the GNSS
FAKRA D connector (Bordeaux) for the LTE antenna.
Warning:
The device is not intended for use without the enclosure.
Do not use the logger's USB port for stand-alone data logging, as it may damage the USB port, which won't be covered under warranty.

The contents below specify the conditions to be ensured for the operation of ReXgen Air.
When inserting the SIM card in a ReXgen Air device, open the lid on the SIM slot correctly and carefully. Mishandling the SIM slot lid can damage the device and the SIM card inside.
Also, ensure the SIM is inserted, as shown in the images above (Chip facing down).
Since it is not required to provide a common ground between nodes, it is possible to have ground offsets. Each node may observe different single-ended bus voltages (common mode bus voltages) while maintaining the same differential voltage. Operating a CAN system with large ground offsets can increase electromagnetic emissions. If the system is sensitive to emissions, steps must be taken to eliminate ground offsets.
ISO-11898 requires that the CAN bus have a nominal characteristic line impedance of 120Ω. Therefore, the typical terminating resistor value for each bus end is 120Ω. Bus termination is used to minimise signal reflection on the bus.
It is always recommended to keep the nominal voltage within the specified rate. The device also has internal protection against low energy voltage events due to supply wire noise.
CAN Bus Isolators and USB Isolators can be purchased separately
Do not use the logger's USB port for stand-alone data logging, as it may damage the USB port, which won't be covered under warranty.
Always mount the device in a way that minimises vibration exposure and accounts for the IP rating of damage. Air is supplied with four screws to assist you with mounting.
An external active FAKRA C or FAKRA D antenna with a supply voltage of 3V is required for GNSS and LTE data logging. It is to be ensured that the antenna is connected correctly (at all times) and that it is not loose when the ReXgen Air is powered on. Operation with a loose antenna or without the antenna entirely can lead to GNSS/LTE data loss.
4 LEDs are installed on ReXgen Air for indicating the CAN/CAN FD logging activity.

The ReXgen Air has an automotive-style 24-pin Molex Connector. (This enables the device to be easily and robustly installed in production machines). Molex 24 PIN to D Sub 25 connector can be purchased separately.
*ReXgen Air requires an external antenna to be purchased in addition to the extension cable. The unit's price does not include the external antenna, which can be purchased off the shelf.
Male 25-pin Standard D Type connector (Mini 50 to D Sub 25 cable Sold separately).
The connector needs to be tightened properly to make a proper connection, ensuring reliable operation.
Each CAN/CAN FD bus end 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.
Do not use the logger's USB port for stand-alone data logging, as it may damage the USB port, which won't be covered under warranty.
