Contactless reader 1708Crocodile


Contactless J1708 reader

1708Crocodile is designed for safe data reading from J1708 bus (SAE J1587) of vehicles. Contactless reader is used within vehicle telematics and GPS tracking systems for receiving various parameters of vehicle operation from the bus: speed, RPM, oil pressure & temperature, fuel volume & consumption, etc.

Data reading occurs without electrical connection and without damaging wires. 1708Crocodile works in “listen” mode only, i.e. it does not change original J1708 messages and does not send any signals to CANbus.

Advantages of 1708Crocodile

Power supply from vehicle

All Crocodile contactless readers have built-in voltage regulator, which allows to power supple the reader from on-board electrical network of vehicle, without using any power adapters. Also, power supply can be done from voltage output of telematics unit (special model of Crocodile).

Sealed housing

Housing of Crocodile reader has two special holes for sealing after installation. Delivery set of Crocodile includes sealing rope and a seal with unique ID. After Crocodile is installed, housing is sealed to ensure the reader will not be opened and uninstalled from the wires without a trace.

1708Crocodile can be connected either directly to the tracking device, or through a vehicle data interface.

1708Crocodile provides safe reading of J1708 bus data, transmitting vehicle operation parameters to the tracking device. Among such parameters are fuel consumption, engine operation mode, indicators status, diagnostics codes.

1708Crocodile can receive J1708 bus data in the following vehicles:

    • US manufactured trucks;
    • Volvo vehicles;
    • John Deere tractors;
    • other vehicles with J1708 bus.
