What is ?

M=BUS is a single wire BUS system which is available for inDummy and Onboard use. Both applications are controlled by a Gateway, which is the interface between the M=BUS system, the trigger, the power supply and the PC.



Daisy chain wiring

A coax cable of 2.5mm connects the M=BUS participants in a daisy chain. This cable is also used for supplying power, the trigger signal and the communication within the system.

Independent units

The M=BUS participants are independent (data acquisition) units with complete data conditioning, data storage and a build in battery for stand alone operation. Please visit our M=BUS pages for detailed information.
