GIGABOX FlexRay Active Star

The FlexRay Active Star is an active star coupler for the FlexRay bus system and is used for the decoupling of communication networks as well as for increasing the maximum wiring length.

The higher transmission rates make the FlexRay bus more prone to errors than CAN bus systems. FlexRay networks are typically carefully balanced in terms of wire lengths, termination, parameters etc.

Whenever another FlexRay device is introduced into such a system, e.g. measurement equipment placed in a car boot, this can lead to additional faults in the FlexRay system. GIGABOX FlexRay Active Star reduces the potential impact on the existing network substantially.
