CAN
Controller Area Network (CAN or CAN-bus) is a computer network protocol and bus
standard designed to allow microcontrollers and devices to communicate with each other and
without a host computer. It was designed specifically for automotive applications but is now also
used in other areas.
SAE J1939 is the vehicle bus standard used for communication and diagnostics among
vehicle components. Based on the same architecture FMS protocol dedicated to telematics
systems is available. It has certain standardized parameters available, such as fuel consumption,
engine work-hours, etc. Please visit
http://www.fms-standard.com/ for more information and
message structure.
The FMS-interface is an optional interface of different truck manufacturers. Supported
information is dependent upon vehicle equipment. For the full information set, additional
Electronic Control Units (ECU) may be required. Please contact the manufacturer or your dealer
