Fleet black boxA recorder in every vehicle
Fit one to each vehicle on the J1939 backbone and let FIFO loop recording keep the recent history without anyone touching it.
A vehicle black box for one CAN bus
One CAN channel recorded straight to 8 GB of soldered eMMC, loop recording like a black box once it is full, and a deep sleep that draws under 2 mA. Fit it, forget it, read it when it matters.
1× CAN
ISO 11898-1 up to 1 Mbit/s, raw CAN and SAE J1939, 20000 mps.
8 GB eMMC
Soldered storage with FIFO loop recording once it is full.
<2 mA sleep
Deep sleep on the vehicle battery with WakeOnCAN.
J2534

Free UK delivery over £499, excluding bulk orders
12 month warranty
Soldered eMMC, no SD card to lose
What makes it a black box
Asleep until the bus speaks
Deep sleep at under 2 mA on the vehicle battery, WakeOnCAN when traffic appears, then straight back down.
Full is never the end of the recording
Logs write straight to 8 GB of soldered eMMC. Once it is full, FIFO logic overwrites the oldest file first, so the most recent data always survives.
Record everything, or just the event
Trigger on a CAN ID, a parameter value or a DM1 counter, with advanced message filtering and cyclic logging.
A live interface when you need one
J2534 pass-thru over micro USB 2.0 streams CAN in real time to diagnostic tools and applications like SavvyCAN.
Open from the file format up
Free REXDESK exports to MDF4, CSV, MATLAB, ASC, BLF and TRC, with REXLIBRARY open libraries for your own tooling.
Built for the harsh end of the vehicle
IP65 in PC+ABS, -40 C to +85 C, 164 g with four mounting holes. Transceiver protected to ±58 V bus faults.
Full specifications, including power figures, protection and dimensions, in the spec sheet below.
Applications
Where REXGEN 1 goes to work
Single bus black box logging, event capture and live diagnostics.
Fleet black box
Intermittent faultsCatch the fault that never happens in the workshop
Leave it on the bus for weeks at under 2 mA. Trigger on the DM1 counter or a parameter value and the event is on the eMMC when the vehicle comes back.
Bench interfaceLogger in the field, interface on the bench
The same device streams CAN live over USB as a J2534 pass-thru, into SavvyCAN or your own application via REXLIBRARY.

Frequently asked questions
Common questions
Is REXGEN 1 a vehicle black box?
It works exactly like one. It records the CAN bus continuously to soldered eMMC with nothing to eject or lose, FIFO logic keeps the most recent history once the 8 GB is full, and deep sleep at under 2 mA means it can stay fitted for the life of the vehicle.
Does REXGEN 1 support CAN FD?
No. REXGEN 1 records classic CAN (2.0 A and B) up to 1 Mbit/s. If you need CAN FD, a second channel or a LIN bus, REXGEN 2 is the right device.
What happens when the 8 GB eMMC is full?
FIFO logic overwrites the oldest file first, so logging never stops and the most recent data is always preserved. Cyclic logging mode is also supported.
Can it work as a live CAN interface?
Yes. REXGEN 1 functions as a J2534 pass-thru device over its micro USB 2.0 port, streaming CAN in real time to diagnostic tools and applications such as SavvyCAN.
Will it drain the vehicle battery?
No. Deep sleep draws under 2 mA and normal sleep under 17 mA, with WakeOnCAN bringing it back the moment the bus becomes active. In normal logging it draws 87 mA at 12 V.
What is the difference between REXGEN 1 and REXGEN 2?
REXGEN 1 has a single classic CAN channel and 8 GB of storage. REXGEN 2 adds a second channel, CAN FD up to 8 Mbit/s, a LIN bus, two digital and two analogue inputs and up to 16 GB of storage.
