For the Voyager™ Infotainment system PT Tronix has developed a high quality of service (high Hi-QoS) data communication networking infrastructure. This is eminently suitable for the streaming of digital audio and video data in a public transport vehicle environm­ent. The CX Bus (CXB) is the technology of choice for Voyager™ Infotainment systems because it is:

 

  • Fast – offers a number of different versions starting from 12Mb/s.
  • Flexible – the network infrastructure can be easily tailored to any coach layout.
  • Future Proof – the system can easily be upgraded throughout the life span of a coach.

 

Voyager™ networking is based on mature technology. It is straightforward to install during the vehicle manufacturing process and easy to repair during the lifetime of the vehicle. This results in a very low total cost of ownership.

 

CXB is an Interface standard which specifies interconnections between Voyager™ devices to aid a robust system operation. It handles all the electrical and physical specifications dealing with the interaction between Voyager™ devices and the Unshielded Twisted Pair cable (UTP) e.g. automatic establishment and termination of a connection to the network, digital data flow control, signal encoding etc.

 

CXB provides the functional means to transfer data between Voyager™ devices free of transmission errors. It provides addressing and channel access control mechanisms that make it possible for Voyager™ devices to communicate within a multipoint network. Most importantly it offers a robust method for the transfer of bit streams over the network.
 

         

 

Voyager™ data communication networking offers:

  • Significant reduction in cost compared to analog systems
    currently in use in public transport vehicles.
  • Reduction in complexity and weight of the Voyager
    wiring harness by eliminating multi core shielded cables (VGA) and multiple audio cables.
  • Ability to deliver premium features such as individually controlled audio and Hi-Quality streaming of digital A/V programs.
  • Keeps Infotainment system future proof by simplifying
    Ûreplacement or addition of extra modules.
  • Ability to individually locate each module in the optimum position within the vehicle
  • Compatible with mass production manufacturing methods, needing no special skills/tools for assembly, service and repair, hence reducing warranty and maintenance cost.
  • Meets automotive EMC requirements using unshielded twisted pair (UTP) cables.
