REXGEN Pro: pinouts, SIM, LEDs and installation

Updated

Find the pin for every signal on the REXGEN Pro JAE 34-pin connector and the INF4219 breakout. This guide also covers the antenna ports, the SIM, the LEDs and mounting.

Connectors at a glance

REXGEN Pro has one JAE compact automotive 34-pin connector, which suits fixed installation in production machines. The optional INF4219 breakout cable turns it into a female 25-way D-Sub connector and an RJ45 Ethernet socket. Signal names stay the same on both sides of the breakout.

INF4219 D-Sub 25 breakout

The INF4219 cable connects the JAE connector to a female 25-way D-Sub connector and an RJ45 socket. It is sold separately.

To split the 25-way D-Sub into 9-way D-Sub leads, use a multi-connect. Choose the 2-way INF4203, with two 9-way D-Sub connectors, or the 5-way INF4204.1. For the signal on each lead with REXGEN Pro, ask technical support.

RJ45 Ethernet

Ethernet is optional. On the breakout, it uses two pairs of a standard RJ45 socket.

Antenna ports

REXGEN Pro needs external antennas for LTE, GNSS and Wi-Fi. They are sold separately, like the breakout cable. Each port is a keyed, colour-coded FAKRA connector, so an antenna fits only its own port.

REXGEN Pro FAKRA antenna ports
Port Colour Antenna
FAKRA Z Water blue Wi-Fi
FAKRA C Blue GNSS, active antenna with a 3 V supply
FAKRA D Bordeaux violet LTE

The LTE and Wi-Fi ports also need active 3 V antennas.

SIM card

Loggers with a non-soldered SIM take a nano SIM in a tray beside the antenna ports.

  1. Eject the tray carefully. Rough handling can damage the logger and the SIM.
  2. Insert the SIM chip facing upwards.
    Close-up of the REXGEN Pro antenna end with the SIM tray removed and a nano SIM above it, chip facing up
    The tray slides out of the antenna end of the logger.
  3. Slide the tray back in. Check that it sits flush before you power the logger.

LEDs

Eight LEDs on the lid show the logging activity. They are numbered 1 to 8.

Wiring the digital inputs

The digital inputs read a voltage below 0.8 V as low and above 2.5 V as high. Drive them from a switch, a transistor, a relay contact or a logic buffer such as a Schmitt trigger. Fit a 1 kΩ pull-up resistor to the +4.5 V instrumentation supply on breakout pin 10.

Four ways to drive a digital input DIGITAL INPUT · WIRING Four ways to drive a digital input Switch Instrumentation supply Pull-up Input A closed switch pulls the input low. NPN transistor Instrumentation supply Pull-up Input Control The transistor turned on pulls the input low. Relay contact Instrumentation supply Pull-up Input Relay coil in a separate circuit closes the contact A closed contact pulls the input low. Schmitt-trigger buffer Instrumentation supply Pull-up Input Signal The buffer output drives the input directly. The input reads low below VIL and high above VIH. Take VIL, VIH, the pull-up value and the maximum input voltage from the product guide. Every circuit shares the module ground.

Keep the total draw on the instrumentation supply at 100 mA or less. The specification lists two digital inputs, and the connector has pins for four.

Wake-up input

REXGEN Pro wakes from sleep on CAN activity, on movement or on a digital input. To set the wake sources, see REXDESK: sleep and wake settings.

The breakout labels a Wake-up# pin. A wake-up pin is held high and wakes the logger when switched to ground for longer than 20 ms. On REXGEN Pro, this pin is not connected, and the JAE connector has no wake-up pin.

Installation

Mounting

Mount the logger where vibration is as low as possible and where IP65 protection is enough. REXGEN Pro comes with four mounting screws.

Screw diameter, body 2.88 mm
Screw diameter, head 5.33 mm
Screw length 33.05 mm

Supply voltage

Keep the supply voltage between 6.5 V and 27 V. The logger has internal protection against low-energy voltage events caused by noise on the supply wires.

Termination and grounding

ISO 11898 specifies a CAN bus with a nominal characteristic impedance of 120 Ω. Terminate each end of the bus with a 120 Ω resistor. Termination keeps signal reflections on the bus to a minimum.

CAN nodes do not need a common ground, so ground offsets can occur. Each node may then see different single-ended bus voltages while the differential voltage stays the same. Large ground offsets can increase electromagnetic emissions. If your system is sensitive to emissions, remove the offsets.

See CAN bus wiring: termination, cable length and grounding.
