Contactless CAN j1939 reader
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.
Engine time monitoring according to CAN data
Fuel consumption monitoring from CAN bus data
Reading engine parameters from CAN bus
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.
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).
Compatible telematics and GPS tracking units
This table contains information on integration tests of CANCrocodile and various telematics units, carried out to confirm compatibility and accuracy of data. To get more detailed info on connection and set up – click on link or logo of corresponding telematics unit in the table.
