REXGEN Air records up to four CAN FD networks on the vehicle, then streams every log to your cloud over LTE. No site visit.
A full CAN logger and an LTE telematics unit in one compact enclosure, built to stay on the vehicle from the first prototype to the production fleet.
Concept and development vehicles are well instrumented. Pre-production and production rarely are, so the field data that proves durability and warranty goes uncaptured. REXGEN Air is built for all four stages.
Every .RXD log uploaded to your own S3 bucket, NAS or server, at a sync rate you set, decoded on arrival.
Up to four CAN or CAN FD channels at 8 Mbit/s, plus a LIN bus.
u-Blox M8U with dead reckoning and geofencing.
16 or 32 GB, soldered in.
Config and firmware, COTA and FOTA, signed.
Motion and orientation at up to 1 kHz, fused with GNSS.
Logs land in the cloud as standard files, then a serverless function decodes them with your DBC. Watch the fleet, storage and last sync from one place.
The full stack, cloud storage, serverless compute and a database. RXD and snapshot data arrive decoded and ready for dashboards.
Upload straight to your own S3 bucket. With a DBC file, a serverless function you deploy from GitHub auto converts to MF4, BLF or CSV. We can also set this up and run it for you.
Secure eMMC protects critical data from corruption and unauthorised access. There is no card to vibrate loose, eject, or walk off.
D-Sub connectors reinsert happily for R&D, but they are not made for the field. REXGEN Air uses an automotive Molex push lock, rated for the vibration, heat and dust of highway and off road use.
Four onboard LEDs provide quick feedback for CAN 0 and CAN 1 logging, GPS satellite connection and AWS/SIM server connection status.
Micro USB for configuration with REXDESK and direct data retrieval.
Standard SIM for the LTE CAT1 modem, behind the front face.
Separate keyed connectors for the LTE and GNSS antennas.
Automotive push lock carrying power, the CAN and LIN buses and the inputs.
REXGEN Air carries the u-Blox M8U. When satellite view drops in a tunnel or a dense yard, inertial dead reckoning fuses the gyroscope and accelerometer with the last fix, so the track stays continuous. Geofencing is built in.
Tailor behaviour through an open XML configuration in REXDESK or by hand. Filter signals, embed GNSS onto the CAN bus, route between buses as a gateway, insert faults and support UDS service 0x22.
REXLIBRARY, our open source toolkit on GitHub, handles file conversion, so you can build your own applications and cloud functions. Worked examples for every configuration feature are in the REXGEN XML examples on our docs site.
<!-- embed GNSS speed onto CAN, filter one ID --> <Channel source="GNSS.Speed" tx="CAN1" id="0x350"/> <Filter bus="CAN2" pass="0x18FEF100"/> <Gateway from="CAN1" to="CAN2" uds="0x22"/>
Three typical applications.
Recording four CAN networks and an analogue temperature sensor on vehicles converted to electric power, uploading continuously to the customer central server. Rugged connectors and secure eMMC keep data intact in harsh, remote conditions worldwide.
Real time tracking of vehicle performance, driver behaviour and fleet status, with remote reconfiguration as needs change. Custom applications built on REXLIBRARY log directly to the customer AWS S3 buckets.
Uninterrupted data collection across an EV battery lifespan for warranty, where data loss is unacceptable. The device also acts as a gateway, adjusting time and date through custom CAN commands. Secure eMMC is the deciding advantage.
From the verified specification matrix and the REXGEN Air documentation.
CAN to cloud data logger with up to 4 CAN and CAN FD channels, LTE, GNSS and 6-axis IMU. Configure over the air, data lands in your own AWS stack.
In the box:
External antenna sold separately.
Yes. A standard SIM fits behind the front face and feeds the LTE Cat1 modem. Once it is in, logs upload over the network with no further handling.
Every .RXD log uploads over LTE to the managed web app or straight to your own AWS S3 bucket, at a sync rate you set, and is decoded on arrival.
Yes. Recording is always local to the soldered eMMC first, then streamed when a link is available. Nothing is lost out of coverage, and FIFO and partitioning protect the most recent data until it uploads.
Yes. A serverless function decodes each log with your DBC on arrival. In S3 only mode a function you deploy from GitHub auto converts to MF4, BLF or CSV.
Yes. Configuration and firmware update over the air, COTA and FOTA, and both are signed.
REXGEN 2 is the local CAN logger. REXGEN Air adds the LTE modem, GNSS with dead reckoning, a 6 axis IMU and cloud upload, so data leaves the vehicle without a site visit.
In stock now in 16 GB and 32 GB, shipping from Bedford, with REXDESK and a 12 month warranty in the box.
