Vehicle Data Reader for Buses

The FMSCrocodile is a vehicle data reader for buses. It is a tool for Telematics / GPS Systems used for data reading from one or more buses into CAN/S6 Telematics Interface.

It obtains a large range of vehicle operating parameters via one CAN-port of telematics unit.

The Wagencontrol FMSCrocodile is a vehicle data reader for buses.

Firstly, the FMS Crocodile safely reads CAN bus data without electrical contact with CAN wires. It automatically generates and sends FMS and Telematics messages to it output CAN 2.0B interface which is J1939 protocol.

Secondly, the telematics unit configuration is simplified. This because unnecessary data from the bus is filtered and only useful information for vehicle telematics purposes is sent.
