REXGEN 2 and REXGEN 2 IMU GNSS: overview and specifications
This series covers REXGEN 2 and REXGEN 2 IMU GNSS in five guides: this overview, the quick start guide, pinouts, recording, then motion and position. This guide covers what the two versions share, how they differ, the full specifications and the safety rules.
Two versions, one logger
REXGEN 2 and REXGEN 2 IMU GNSS share the same enclosure, two connectors, CAN FD, LIN and input hardware, supply and software. REXGEN 2 IMU GNSS adds a 6-axis inertial sensor (accelerometer and gyroscope), a GNSS receiver with an external antenna and wake on movement. Both are configured and read with REXDESK, which is free.
- Two CAN or CAN FD channels up to 8 Mbit/s, and one LIN channel.
- Two analogue and two digital inputs, sampled at up to 1 kHz.
- Soldered eMMC storage with FIFO logic once full. There is no SD card.
- Works as a J2534 pass-thru interface over micro USB 2.0.
- Live trace of raw CAN frames and SAE J1939.
- Sleep modes with wake-up on CAN. REXGEN 2 IMU GNSS also wakes on movement.
- Advanced trigger and filter conditions, and CAN error logging.
- Internal temperature sensor.
- IP65, stackable, pocket-sized.

Safety and liability
Read these rules before you install or handle the logger. They apply to every guide in this series.
- Have the logger installed, connected and commissioned by a qualified professional, following all applicable safety rules.
- Disconnect the logger completely before you handle it. Disconnect any separately supplied output load circuits too.
- Do not connect the housing to ground externally. This disables the reverse voltage protection of the supply. A reverse voltage then destroys the supply circuits.
- Fit every connector with its plug and any protection caps it needs to keep IP65 protection.
- Never immerse the logger in water or any other liquid.
- Do not use the logger without its enclosure.
- Use only components from the starter kits or the accessories supplied.
- Only the manufacturer may repair the logger.
- Keep substances that contain solvents away from the label.
Influx Technology accepts no liability for damage caused by normal wear, installation errors or faults in operation or maintenance. The same applies when the logger, its accessories or the software are modified without Influx Technology's prior approval.
