Crocodile

Contactless reader CANCrocodile

CANCrocodile is designed for safe data reading from vehicle CAN bus. Contactless reader is used within vehicle telematics and GPS tracking systems for receiving various parameters of vehicle operation from CANbus: speed, RPM, oil pressure & temperature, fuel volume & consumption, etc.

Data reading occurs without electrical connection and without damaging CAN wires. CANCrocodile works in “listen” mode only, i.e. it does not change original J1939 messages and does not send any signals to CANbus.

CANCrocodile application

Advantages of CANCrocodile

Safe connection to CAN bus

CANCrocodile does no damage to insulation of wires and has no direct electrical contact with CANbus. Data reading occurc in a contactless way – CANCrocodile detects magnetic field around CAN-High and CAN-Low wires.

Strong fixation of CAN bus wires

The design of the body provides perpendicular fixing of the wires to reading surface. This way of fixing will not allow the CAN bus wires to slip from the CANCrocodile reading surface.

A soft pressure pad in the upper part of the housing tightly presses the wires to reading surface.

LED indication of operation modes

Red indicator – power is on, blinking green indicator – messages receipt from CAN bus. Indicaters allow to test the operability of the reader without dismantling and connecting to monitoring terminal.

 

CANCrocodile installation

CANCrocodile installation

Open CANCrocodile housing.

Place  CAN-High and  CAN-Low wires in the grooves of CANCrocodile housing according to the marks on reading surface.

Close CANCrocodile housing in a way to engage the latch. Put sealing rope through special holes and seal housing, if necessary (recommended).
